Enrolling in and Appealing Medicare: A Practical Guide

Summary. This guide runs Medicare in order: the enrollment decision six months before 65, the employer coverage verification, the Medigap window, the Advantage comparison, the annual review, hospital admission, the notices that carry appeals, the five levels, and the cost programs.

For the law — eligibility, the parts, exclusions, the skilled nursing benefit, and the appeal structure — see Medicare. This guide is what to do, when.

The organizing fact: almost every serious Medicare problem is a timing problem, and most are irreversible.

Stage 1: Six months before turning 65

Start here, not at 65.

Question one: will you have coverage through current employment at 65 — yours or a spouse's?

• No → enroll in Parts A and B during your Initial Enrollment Period: the three months before your birthday month, the birthday month, and the three months after. Enroll before the birthday month so coverage begins on time.
• Yes → go to question two.

Question two: how many employees does that employer have?

• 20 or more → the group plan pays first, Medicare second. You may delay Part B without penalty and use a Special Enrollment Period later.
• Fewer than 20 → Medicare generally pays first. Delaying Part B can leave you with almost no coverage, because the group plan pays only as secondary. Enroll in Part B.

Get the answer in writing from HR, and keep it. This single question determines whether delaying Part B is safe or catastrophic.

Two things that are not current-employment coverage: COBRA and retiree coverage. Neither supports a Special Enrollment Period, and relying on either accrues a lifetime penalty.

If you are contributing to a health savings account, stop contributions six months before enrolling in Medicare — Part A enrollment is retroactive up to six months, and contributions in that window become excess contributions with a tax penalty.

Take Part A even if you delay Part B, unless you are contributing to an HSA, in which case delay both.

Stage 2: Enrolling

If you are already receiving Social Security at 65, enrollment in Parts A and B is automatic and the card arrives about three months before your birthday. Part B may be declined — and should be, if you have qualifying current-employment coverage at a large employer.

Otherwise, enroll through Social Security — online, by phone, or in person. Online takes about fifteen minutes.

For a Special Enrollment Period after employment ends, you will need two forms: the enrollment application and an employer-completed statement verifying the group coverage dates. Get that form completed before you leave the job, because tracking down a former employer's benefits department months later is the most common cause of delay.

Calendar the eight-month window — it begins when the employment or the coverage ends, whichever is first, not when COBRA ends.

Stage 3: The Medigap window — six months, once

The month you are 65 and enrolled in Part B, a six-month window opens during which any insurer must sell you any policy it offers, at its best rate, without medical underwriting.

After it closes, in most states, insurers may refuse or surcharge based on health.

What to do in that window:

1. Decide between original Medicare with a supplement and Medicare Advantage — see Stage 4.
2. If choosing original Medicare, compare Medigap plans by letter, because the benefits within a letter are standardized by law and the only differences are price, the insurer's rate-increase history, and the rating method (attained age, issue age, or community rated — which determines how fast the premium rises).
3. Buy it during the window. Waiting even a few months can mean underwriting.

The guaranteed issue rights that exist outside the window: losing employer coverage; an Advantage plan leaving your area or you moving out of it; an insurer's misconduct; and — the important one — the 12-month trial right for a person who joined Advantage at 65 and disenrolls within a year.

Check whether your state requires continuous or annual guaranteed issue. A handful do, which makes the decision fully reversible and changes everything in Stage 4.

Stage 4: Choosing your path

Run this comparison with your actual situation, not in the abstract:

The asymmetry that should drive it. Choosing original Medicare with a supplement at 65 preserves the option to move to Advantage at any later annual enrollment. Choosing Advantage may foreclose the reverse move, because after the six-month window a Medigap insurer may underwrite — except during the 12-month trial right.

So if you are uncertain, the reversible choice is original Medicare with a supplement, and the trial right is your safety net if you start with Advantage.

Stage 5: The annual review — one hour, every autumn

Open enrollment runs 15 October to 7 December. Do this every year, without exception.

1. Read the Annual Notice of Change your plan mailed in September. It states every change: premium, deductible, copays, network, formulary.
2. Check the formulary against the drugs you actually take. For each: still covered? which tier? prior authorization or step therapy added? A drug moved from tier 2 to tier 4 can change annual cost by thousands.
3. Check the network against the providers you actually see, by name — and then call each office to confirm, because directories are frequently wrong.
4. Compare total expected cost, not premium: premium + deductible + expected copays + the out-of-pocket maximum in a bad year.
5. Run the plan finder with your specific drug list. The cheapest Part D plan differs entirely by person and by year.
6. Check star ratings and complaint data, which are published.

Two other windows: the Medicare Advantage Open Enrollment Period, 1 January to 31 March, to switch Advantage plans or return to original Medicare; and Special Enrollment Periods triggered by a move, loss of other coverage, a plan leaving the area, or newly qualifying for Extra Help or a Medicare Savings Program.

Stage 6: On hospital admission — ask on day one

"Am I an inpatient, or am I under observation?"

Why it matters. Observation is outpatient status, billed under Part B. Observation days do not count toward the three-day inpatient stay required for the Part A skilled nursing facility benefit. A patient can occupy a hospital bed for four nights and have no skilled nursing coverage at all.

What to do:

• Ask on day one, and again each day. Get the answer in writing.
• Read the observation notice the hospital must give when observation extends beyond a stated number of hours.
• Ask the attending physician to reconsider the status if the clinical picture supports admission. This must be done while you are still in the hospital; it cannot be fixed at discharge.
• If discharge to a skilled nursing facility is contemplated, confirm the qualifying stay before the transfer.

Stage 7: When services are ending — the two-day appeal

Before a hospital discharges you, or a skilled nursing facility, home health agency, or hospice ends services, you receive a written notice — an Important Message from Medicare or a Notice of Medicare Non-Coverage.

That notice carries a right to an immediate, free review by a Quality Improvement Organization, decided in about two days, with services continuing during the review.

The phone number is on the notice. Call it. This is the single highest-value action available to a Medicare beneficiary and it costs nothing.

Do not accept "you have plateaued." Coverage does not require improvement; skilled care to maintain a condition or prevent deterioration can qualify.

Also ask for the "demand bill" where a provider says Medicare will not pay: the provider can be required to submit the claim so that Medicare, not the provider, makes the coverage decision — creating an appealable determination where otherwise none exists.

Stage 8: Appealing a denied claim

Read the Medicare Summary Notice (original Medicare) or the plan's denial, and find the deadline.

Original Medicare — five levels:

1. Redetermination by the contractor — 120 days to file; 60 days to decide.
2. Reconsideration by a Qualified Independent Contractor — 180 days.
3. Administrative Law Judge hearing — 60 days, subject to an amount-in-controversy threshold. This is where a meaningful share of denials are reversed, and where representation starts to matter.
4. Medicare Appeals Council — 60 days.
5. Federal district court — 60 days, higher amount in controversy.

Medicare Advantage and Part D run a parallel structure — plan reconsideration, an independent review entity (to which an adverse reconsideration must be forwarded automatically), then an ALJ — with 72-hour expedited timeframes, and 24 hours for an expedited Part D coverage determination.

What makes an appeal work, at any level: a letter from the treating physician tying the service to the applicable coverage criteria; the records; a citation to the Medicare coverage rule or national or local coverage determination; and — for an Advantage denial — the point that a plan may not apply criteria more restrictive than original Medicare's.

Stage 9: Prescription problems

Four requests solve most of them, and all are decided quickly:

• Formulary exception, for a non-formulary drug, with a prescriber's supporting statement.
• Tiering exception, for a lower cost-sharing tier.
• Prior authorization, submitted by the prescriber.
• Step therapy exception — already tried and failed, contraindicated, or expected to be ineffective.

Timeframes: 72 hours standard, 24 hours expedited. Ask for expedited review whenever delay could harm health.

Ask for the transition fill by name — a temporary supply for a new enrollee or when a drug is removed from the formulary mid-year. Pharmacies frequently do not offer it.

And know the out-of-pocket cap and the option to spread costs across monthly payments; both are new and both are under-used.

Stage 10: Reducing what you pay

IRMAA redetermination. If your income dropped because of a life-changing event — work stoppage or reduction, marriage, divorce, death of a spouse, loss of income-producing property, or loss of a pension — request a redetermination rather than paying a surcharge based on a tax return from two years ago. Routinely granted, rarely requested.

Medicare Savings Programs. State-administered, they pay the Part B premium and, at lower income levels, deductibles and coinsurance. QMB status prohibits providers from billing you for Medicare cost sharing at all — a protection routinely violated; if you are billed, say so in writing and complain.

Extra Help (Part D low-income subsidy), applied for through Social Security — substantially reduces or eliminates Part D costs.

State Pharmaceutical Assistance Programs, in many states.

Medicaid, for those who qualify.

Your SHIP will screen you for all of these in one appointment, at no cost.

Stage 11: If there is a settlement or a work injury

Workers' compensation, liability, and no-fault coverage are primary to Medicare. Two consequences follow, and both must be handled during a settlement rather than after:

• Conditional payments. Medicare may pay and then seek reimbursement from the settlement. The resolution process is slow; start it early.
• Set-asides. A settlement resolving future medical expenses may require a Medicare set-aside to protect the program's interest.

Any personal injury or workers' compensation settlement involving a Medicare beneficiary must account for this. See Personal Injury Claim Toolkit.

Writing an appeal that actually works

Most Medicare appeals fail for the same reason: they argue that the denial is unfair rather than that it is wrong under the rule the decision-maker is applying. The reviewer at every level has a standard in front of them. Your job is to meet it, on the page, in their language.

The four-part structure that works at every level:

1. Identify the decision precisely. Claim number, date of service, provider, the exact denial code and denial language, and the level you are appealing to. Reviewers process volume; a filing they cannot immediately match to a record gets returned, and the clock does not stop while it travels.

2. State the coverage rule. Do not paraphrase — quote it. Medicare's coverage rules live in the statute, in the regulations, in national coverage determinations, in local coverage determinations issued by the contractor for your region, and in the Medicare benefit policy manuals. All of them are published and searchable. A denial that conflicts with a local coverage determination in your own contractor's jurisdiction is the easiest kind of appeal to win, and it is won by attaching the determination.

3. Apply the facts to the rule, element by element. If the rule requires that the service be reasonable and necessary for the diagnosis or treatment of illness or injury, walk through each word. If the skilled nursing rule requires daily skilled services, show the daily skilled services in the chart. Write it as a numbered list keyed to the rule's own elements. Reviewers are checking boxes; hand them the boxes checked.

4. Attach the evidence, indexed. Records, orders, therapy notes, imaging, and — above all — a letter from the treating physician. The physician letter is the highest-leverage document in the entire process, and it is the one most often missing.

What a useful physician letter contains. Not "this patient needs this service." Instead: the diagnosis and its severity; what has already been tried and what happened; why the denied service is medically necessary for this patient specifically; the clinical consequence of not providing it; and — the sentence that decides cases — an explicit statement tying the service to the coverage criterion. Something like: "Skilled nursing services are required daily to manage her wound and prevent deterioration; without skilled intervention the wound will progress and result in rehospitalization." Physicians will usually sign a letter you draft for them. Draft it.

One more argument, specific to Medicare Advantage. A plan may not apply coverage criteria more restrictive than original Medicare's. If the plan denied something that original Medicare would cover, say exactly that, cite the original Medicare rule, and note that the plan's internal criteria cannot narrow the benefit. This argument wins cases and is almost never made by unrepresented beneficiaries.

Send it so you can prove you sent it. Certified mail, fax with a confirmation, or the plan's portal with a screenshot. Then follow up by phone and get the reviewer's name.

What the levels actually feel like

Level 1, redetermination. A paper review by the same contractor that denied the claim, often by a different reviewer. Reversal rates are modest. It costs a stamp and 120 days of patience, and it is a prerequisite, so file it — but do not be discouraged by losing it. Many meritorious claims lose at level 1 and win later.

Level 2, reconsideration. A Qualified Independent Contractor — a different organization — reviews on the record. This is the last purely paper stage. Everything you want considered later should be in the file by the end of level 2, because introducing new evidence at the ALJ level can require an explanation for why it was not submitted earlier.

Level 3, the ALJ hearing. This is the level that matters. A hearing before an administrative law judge, usually by telephone or video, where you or your representative can speak, the treating physician can testify, and the judge asks questions. Reversal rates here are dramatically higher than at levels 1 and 2 — high enough that the difference is the central strategic fact of Medicare appeals. There is an amount-in-controversy threshold, adjusted annually, and claims may be aggregated to meet it, which matters for recurring services.

Prepare for it the way you would prepare for any hearing: a one-page outline of the elements; the physician available by phone; the record tabbed; and an opening that says in thirty seconds what the service was, what rule covers it, and why the record satisfies it.

Level 4, the Medicare Appeals Council. Paper review, deferential, slow.

Level 5, federal district court. A civil action with a higher amount in controversy. Rare, and by this point you are litigating an administrative record under an arbitrary-and-capricious style of review rather than trying the merits fresh.

The practical lesson: get to level 3, and be ready when you arrive.

Timing the whole thing: a life calendar

Age 64 and 6 months. Answer the employer question. Get the letter. Stop HSA contributions if you plan to enroll at 65.

Age 64 and 9 months. If enrolling, apply — the three months before the birthday month give you coverage that begins on time.

Age 65, month of enrollment in Part B. The six-month Medigap window opens. Decide and buy.

Age 65 through 66. If you chose Advantage, the 12-month trial right is alive. If it is not working, use it.

Every September. Read the Annual Notice of Change.

Every 15 October to 7 December. Run the one-hour review.

Every January. Confirm the new plan took effect, the new card arrived, and the pharmacy has the new plan on file. January pharmacy problems are extremely common and are almost always a data-entry issue at the counter rather than a coverage denial.

Whenever income drops. File the IRMAA life-changing-event request.

Whenever a move is planned. Check the plan's service area before signing a lease.

Whenever a hospital admission happens. Ask about observation status on day one.

Whenever a notice arrives ending services. Call the QIO number on the notice, that day.

Four people, four decisions

Abstract rules are hard to apply. Here are four situations that cover most of what actually walks through a counselor's door.

Diane, 64 and 8 months, still working at a hospital with 4,000 employees

Diane's employer has far more than 20 employees, so the group plan is primary and Medicare would pay second. She may safely delay Part B. But three things still need doing:

1. She should enroll in Part A — it is premium-free for her, it costs nothing, and it can pick up some inpatient cost sharing the group plan leaves behind. Unless she is contributing to a health savings account, in which case Part A enrollment ends HSA eligibility and, because Part A entitlement can be backdated six months, she must stop contributions six months before she eventually enrolls.
2. She should get the employer's coverage confirmed in writing now, while she still works there and the benefits office knows her. That letter, plus the employer-completed verification form, is what unlocks her Special Enrollment Period later. People who retire and then try to reach a benefits department six months later routinely wait weeks.
3. She should calendar the eight-month clock — not from when COBRA runs out, from when the job or the coverage ends.

Diane's actual risk is not the enrollment rule. It is being told, at retirement, "you can just take COBRA and sign up for Medicare when it ends." That advice, given constantly and always in good faith, produces a lifetime Part B penalty and a coverage gap that can run most of a year.

Ray, 65, retiring from a 12-person engineering firm

Ray's employer has fewer than 20 employees. Medicare is primary. If he delays Part B, the group plan pays only what it would pay as secondary — which, with no primary payer actually paying, often means it pays very little, and Ray is functionally uninsured for physician and outpatient services while believing he is covered.

Ray must enroll in Part B during his Initial Enrollment Period. He should also use his six-month Medigap window, because at a small firm the group plan is often expensive and thin, and he is unlikely to get a better shot at guaranteed issue.

The small-employer trap is the most expensive misunderstanding in Medicare, and it is invisible: nothing about having employer coverage feels different at 12 employees than at 200.

Anita, 66, moving from Ohio to Arizona to be near her daughter

Anita has a Medicare Advantage HMO. Her plan's network does not extend to Arizona.

Moving out of the plan's service area triggers a Special Enrollment Period — she is not stuck waiting for autumn. It also triggers a guaranteed issue right to buy certain Medigap policies without underwriting.

The sequence matters. Anita should:

1. Notify the plan of the move before or immediately after it, which starts her window.
2. Decide during the window, not after — guaranteed issue rights expire, usually 63 days from the qualifying event.
3. If she chooses original Medicare, buy the supplement and a standalone Part D plan. Dropping Advantage without picking up Part D leaves her with a Part D late-enrollment penalty and no drug coverage.

The mistake to avoid: assuming a national brand name means national coverage. Advantage networks are county-level. A plan with the same insurer's name in Arizona is a different plan with a different network, formulary, and premium.

Tom, 71, four days in a hospital bed, then a nursing home bill

Tom fell, spent four nights in the hospital, and was discharged to a skilled nursing facility. Three weeks later a bill arrives for the entire nursing home stay. Medicare paid nothing.

Why: Tom was under observation, not admitted. Observation is outpatient. Observation days do not count toward the three-day inpatient stay that the skilled nursing benefit requires.

What could have been done, and when:

• Day one: ask the status. Ask again daily.
• While still in the hospital: ask the attending physician to reconsider — the clinical picture after a fall in a 71-year-old often supports admission. Status can sometimes be changed while the patient is in the bed; it essentially never can be after discharge.
• Before the transfer: confirm with the hospital's case manager that the qualifying stay exists. A single question at the right moment is worth more than any appeal afterward.
• After the fact: ask for a demand bill so Medicare, not the facility, makes the determination — which at least creates something appealable — and pursue the appeal. Recovery is possible but far harder.

Tom's family did everything a reasonable family does. They just did not know there was a question to ask.

The documents to keep, and where

A folder — paper or digital — with six things in it solves most problems before they start:

1. The Medicare card, and a photo of it. Guard the number the way you guard a Social Security number; almost every Medicare scam begins with a request for it.
2. The employer coverage letter and the completed verification form, if Part B was delayed.
3. Current plan documents: the Evidence of Coverage, the formulary, and the summary of benefits — and the September Annual Notice of Change.
4. The current medication list, with dosages, used at every annual review.
5. Provider list, by name, used at every annual review.
6. Appeal correspondence, in date order, with the deadline for the next level written on the front.

Keep a one-page contact sheet: the plan's member services number, the SHIP number, 1-800-MEDICARE, the QIO number for the state, and the Social Security office. In a hospital at 9 p.m. on a Friday, the person who has the QIO number can appeal a discharge and the person who does not cannot.

Deadlines, in one place

Print this. The two-day appeals and the 63-day windows are the ones that get lost, and they are the ones that cannot be recovered.

Ten mistakes, and what to do instead

1. Treating COBRA as current-employment coverage. It is not. Enroll in Part B when the job ends.
2. Waiting until the birthday month to enroll. Coverage starts late. Enroll in the three months before.
3. Skipping the Medigap window. It closes once, and in most states it does not reopen.
4. Comparing plans by premium. Compare total expected cost including the bad-year maximum.
5. Trusting the provider directory. Call each office.
6. Not reading the Annual Notice of Change. Plans change materially every year, and the default is to roll into the changed plan.
7. Accepting "you've plateaued." Maintenance care can qualify. Appeal.
8. Not asking about observation status. Ask on day one, in the room.
9. Missing the two-day QIO appeal. It is free, fast, and services continue. Call the number on the notice.
10. Paying an IRMAA surcharge after a retirement. Request a redetermination for a life-changing event.

Where the free help is

• State Health Insurance Assistance Program (SHIP). Trained volunteer and staff counselors in every state and territory. Not paid by insurers, not selling anything. They will run a plan comparison with your drug list, screen you for every cost-assistance program at once, and help with an appeal. This is the single best resource and it is free.
• 1-800-MEDICARE, 24 hours. Ask for a written confirmation number for any answer you rely on.
• The Quality Improvement Organization for your state — the number is on the discharge notice — for the two-day appeals.
• Area Agency on Aging, for benefits screening, care coordination, and referrals.
• Legal aid and senior legal helplines, which handle Medicare appeals in most states.
• Social Security, for enrollment, IRMAA redetermination, and Extra Help.
• Your state Medicaid agency, for Medicare Savings Programs and dual eligibility.
• Your state insurance department, for Medigap rate comparisons and complaints about an insurer.

A caution about "free" help that is not. Brokers and agents are paid commissions by the plans they sell, which vary by plan, and television advertising for Advantage plans is a marketing channel, not a public service. A broker can be genuinely useful — many are — but ask which plans they are appointed to sell, because they cannot offer what they do not carry. A SHIP counselor has no such constraint.

Special situations that do not fit the standard path

Under 65 and disabled. Medicare entitlement begins after 24 months of Social Security disability benefits — with no waiting period for ALS, and a separate track for end-stage renal disease. The Medigap problem is severe: federal law does not guarantee a Medigap policy to a beneficiary under 65, and only some states require insurers to offer one. In states that do not, an under-65 beneficiary may find original Medicare with a supplement effectively unavailable and Advantage the only workable option. Check the state rule before assuming a path exists. Note also that turning 65 while already on Medicare opens a fresh six-month Medigap window — a genuinely valuable second chance that is almost universally missed.

Still working past 65 at a small employer. Covered above under Ray, but worth repeating in a different form: at fewer than 20 employees, the group plan's own terms often say it pays as though the employee had Medicare, whether or not the employee actually enrolled. Read the plan document.

Two spouses, two employers, different sizes. Coverage through a spouse's current employment counts, and the employer-size rule looks to the employer of the person whose work generates the coverage. A 66-year-old covered through a 62-year-old spouse's job at a 5,000-person company may delay Part B; the same person covered through a spouse's 8-person company generally may not.

Living abroad. Medicare does not pay for care outside the United States except in narrow circumstances. Someone retiring abroad still faces the Part B penalty question, because living overseas is not a basis to delay without penalty unless there is qualifying employment coverage. Many expatriates conclude they should enroll in Part B anyway and pay the premium as insurance against returning; others accept the penalty. It is a real decision with real numbers on both sides, and it should be made deliberately rather than by default.

Incarceration. Medicare generally will not pay for care while incarcerated, but Part B premiums keep accruing if the person is enrolled — and dropping Part B creates a penalty on re-enrollment. Release triggers a Special Enrollment Period in current practice. This is an area where a SHIP counselor or a reentry legal services program is worth consulting early; see Clearing Your Criminal Record.

Dual eligibility with Medicaid. A person eligible for both programs has extra protections and extra complexity: Medicare pays first, Medicaid fills gaps, QMB status bars balance billing entirely, and special-needs Advantage plans exist for dual eligibles. It also means a change in Medicaid eligibility can silently disrupt Medicare cost sharing. Any change in income or assets should trigger a call.

Hospice. Electing the Medicare hospice benefit changes the architecture: hospice covers care related to the terminal illness, original Medicare continues for unrelated conditions, and an Advantage plan continues for unrelated care. Families are frequently told hospice means "giving up Medicare," which is wrong. Hospice can also be revoked, and a beneficiary can return to standard coverage.

A death in the family. A surviving spouse or executor may need to appeal a claim for the decedent. The right survives, and the estate's representative may pursue it — one more reason the appeal folder matters. See Administering an Estate.

Scams, and how to recognize them

Medicare fraud costs the program billions and costs individual beneficiaries their identity, their money, and sometimes their coverage. The patterns are consistent enough to be listed.

Nobody from Medicare will call you to ask for your Medicare number, to offer a free brace, to send genetic testing kits, or to say your card has expired and a new one is coming. Medicare does not issue new cards on request from a caller and does not sell anything.

Red flags: unsolicited calls or door-knocks; "free" equipment, testing, or supplies in exchange for the Medicare number; pressure to decide immediately; a caller who already has some of your information and wants you to "confirm" the rest; offers of a plan enrollment over the phone from a caller you did not contact; and anyone asking you to sign a blank form.

What to do: hang up. Do not confirm anything, including information they appear to already have. Report it to 1-800-MEDICARE and to the Senior Medicare Patrol in your state, which exists for exactly this.

Read your statements. The Medicare Summary Notice, or the Advantage plan's explanation of benefits, lists every service billed in your name. Scan it for services you did not receive, dates you were not seen, and providers you do not recognize. This is how organized billing fraud is caught, and beneficiaries are the only people positioned to catch it. A phantom claim also matters to you directly: fraudulent billing for equipment or services can exhaust a benefit you later need, and it is far easier to clear when reported within weeks.

A note on the phone calls

Nearly everything in this guide runs through a phone call to a plan, to Social Security, or to 1-800-MEDICARE. Four habits make those calls dramatically more productive:

1. Write down the date, the time, the representative's name or ID, and a reference or call number. Ask for the call number explicitly; every system has one.
2. Ask the representative to state the rule they are relying on, and where it is written. "Can you tell me which plan document or Medicare rule says that?" is a polite question that produces either a citation or an admission.
3. Ask for it in writing. A plan must provide a written denial. A verbal "that's not covered" is not a denial and cannot be appealed — so convert it into one.
4. If the answer sounds wrong, call back. Frontline answers vary. Two different answers to the same question is information: it means the question is genuinely contested and should be escalated to a supervisor or put in writing.

None of this is adversarial. It is simply the difference between a conversation that leaves a record and one that does not — and in a system where every right runs on a deadline measured from a written notice, the record is the whole game.

Frequently asked questions

Do I have to sign up at 65? Only if you lack current-employment coverage at an employer with 20 or more employees. COBRA and retiree coverage do not count.

What if I missed my window? General Enrollment Period, 1 January to 31 March, with a permanent premium penalty. Ask about equitable relief if you were misinformed by a federal employee.

Can I switch from Advantage to original Medicare? Yes, at annual enrollment — but buying a Medigap policy may require underwriting unless a guaranteed issue right applies.

Does Medicare cover a nursing home? Skilled care only, up to 100 days per benefit period, after a three-day inpatient stay. Never custodial long-term care.

What is a demand bill? A request that the provider submit the claim so Medicare decides coverage, creating an appealable determination.

Who helps for free? Your SHIP — trained, unbiased counselors in every state, not paid by insurers.
