What Medicare
Doesn't Cover — and
How to Fill the Gaps
Medicare covers a lot — but it was never designed to cover everything. A serious illness, a hospital stay, or a cancer diagnosis can leave significant costs even with Medicare Advantage's out-of-pocket maximum in place — and Original Medicare or Medigap have their own gaps too. Here's what those gaps look like, and what options exist to address them.

You on Your Own
A few costs consistently catch people off guard — usually during the worst possible moment. Here are the ones that matter most.
Your Out-of-Pocket Max Is Real Money
$4K–$9K+If you're on Medicare Advantage, your plan does cap what you owe — but that cap only applies to services your plan actually covers, and it can still be thousands of dollars before you get there. If you're on Original Medicare without Medigap, Part B coinsurance has no cap at all.
Part A Hospital Deductible
$1,736 per stay$1,736 in 2026, applying per benefit period — not per year. This applies if you're on Original Medicare alone, or on Medicare Advantage up to your plan's out-of-pocket max. Most Medigap plans (including Plan G) cover this in full, so it's typically not a gap if you have one.
Skilled Nursing Facility Days 21–100
$217/day (2026)$217/day in 2026 through day 100. Real exposure on Original Medicare alone or Medicare Advantage — but most Medigap plans (including Plan G) cover this in full, so it's generally not a gap if you have Medigap.
Long-Term Custodial Care
Not coveredMedicare does not cover assisted living, most nursing home stays beyond skilled care, or in-home custodial care.
What a Cancer Diagnosis Could Mean — Even With Medicare Advantage
Your MOOP caps what you owe for covered, in-network care — but hitting it is still real money, and several other costs fall outside it entirely. Here's a simplified illustration of what can accumulate during a cancer treatment year:

What Medicare Leaves Behind
These products are not Medicare plans — they're separate supplemental health insurance policies designed to work alongside Medicare. They're governed by state insurance law, not CMS Medicare marketing rules, and can be discussed and presented alongside your Medicare coverage options.
Most of these products ask a few health questions as part of applying, and acceptance isn't guaranteed for every applicant — some conditions may be excluded or limit which products are available to you. Your advisor will let you know what applies to your specific situation before you apply for anything.
Cancer Insurance
Cancer insurance pays benefits directly to you — not to your doctor or hospital — upon a cancer diagnosis or during cancer treatment. Benefits can be used for anything: medical bills, mortgage payments, transportation to treatment, household expenses, or simply to replace income lost during recovery.
Sample rate shown for a 65-year-old, non-smoker, lump-sum benefit — premiums vary by age. Also varies by health, state, and carrier.
- Lump-sum payment upon first diagnosis (often $10,000–$25,000)
- Per-treatment benefits for chemotherapy, radiation, surgery
- Hospital confinement daily benefits during cancer treatment
- Pays regardless of other insurance — stacks on top of Medicare
- No network restrictions — use any doctor, any facility
- Benefits paid directly to you, not the provider
Part B chemotherapy coinsurance, non-covered drugs, lost income, transportation, and any non-medical costs associated with treatment and recovery.
Worth knowing: most cancer policies exclude or pay a much smaller benefit for non-melanoma skin cancers (basal cell and squamous cell carcinoma) — the full lump-sum benefit typically applies to melanoma and other invasive cancers. Exact terms vary by carrier and policy; your advisor will confirm what a specific policy covers.
Heart Attack & Stroke Insurance
Heart disease and stroke are the leading causes of death and disability in the United States — and among the most expensive health events a Medicare beneficiary can face. Heart and stroke policies pay lump-sum cash benefits upon diagnosis of a qualifying cardiac or cerebrovascular event.
Sample rate shown for a 65-year-old, non-smoker, combined heart/stroke benefit — premiums vary by age. Often bundled with cancer coverage.
- Lump-sum benefit upon heart attack diagnosis (typically $10,000–$20,000)
- Separate benefit for stroke diagnosis
- May include additional benefits for angioplasty, bypass surgery, or cardiac stenting
- Benefits for rehabilitation and recovery care
- Pays regardless of Medicare — no coordination of benefits required
- Cash in hand — use it for any expenses, medical or otherwise
Hospital deductibles per admission, Part B coinsurance on outpatient cardiac care, skilled nursing facility coinsurance, and the significant non-medical costs of cardiac recovery (home modifications, transportation, lost income).
Hospital Indemnity Insurance
Hospital indemnity plans pay a fixed daily, weekly, or per-admission benefit for each day you're hospitalized — regardless of what your actual bills are. They're one of the most versatile supplemental products for Medicare beneficiaries because they address the broadest range of hospital scenarios, not just specific conditions.
Sample rate shown for a 65-year-old — premiums vary by age. Higher daily benefits or SNF coverage increases premium. Many plans are guaranteed issue.
- Fixed daily benefit for each inpatient hospital day (often $100–$400/day)
- Additional benefits for ICU confinement
- Skilled nursing facility daily benefits (days 21–100 coverage)
- ER visit benefits even if not admitted
- Often guaranteed issue or simplified underwriting for ages 60–79
- Pairs especially well with High-Deductible Plan G Medigap
The Part A hospital deductible that applies per benefit period, skilled nursing facility coinsurance for days 21–100, and the general financial stress of an unexpected inpatient stay.
Home Health & Recovery
Medicare's home health benefit is real but narrow — skilled, intermittent nursing or therapy, only if you're certified "homebound" under a doctor's plan of care. It does not cover 24-hour care, custodial or personal care alone (help with bathing, dressing, daily living when that's the only need), homemaker services, or companion care. A home health and recovery policy bridges exactly that gap — the weeks or months of step-down care, in-home assistance, or daily-living help that Medicare either doesn't cover or only partially covers.
Sample rate shown for a 65-year-old — premiums vary by age. Daily benefit amount is selectable at the time you apply. More affordable than standalone long-term care insurance, with easier underwriting — worth knowing, though: some carriers pay this as true cash (the full daily amount regardless of actual cost, no receipts needed), while others reimburse actual expenses against submitted bills up to that daily cap. Only the cash-indemnity structure can pay an informal family caregiver rather than a licensed provider. Your advisor will confirm which structure applies to any specific policy.
- Daily benefits for in-home care after hospitalization
- Adult day care and assisted living facility benefits
- Coverage for custodial care Medicare won't pay for
- Typically covers 1–3 years (distinct from long-term care insurance)
- More affordable and easier to qualify for than long-term care policies
- Can be triggered by hospitalization, cognitive impairment, or ADL limitations
Custodial care Medicare doesn't cover, the period after Medicare's skilled nursing benefit ends, and the significant cost of in-home assistance during recovery from surgery, stroke, or a major health event. Being able to afford care at home also means staying in familiar surroundings during recovery, and giving family caregivers real options instead of shouldering everything alone by default.
Works Alongside Medicare
These products don't replace Medicare — they layer on top of it. Here's how a claim typically works when you have both Medicare and a supplemental policy.
Medicare Pays First
Medicare processes the claim and pays its approved share of covered outpatient services, or the inpatient benefit structure for hospital stays.
You File a Supplemental Claim
For indemnity-style policies, you submit a claim to your supplemental carrier. For lump-sum policies (cancer, heart/stroke), the benefit triggers at diagnosis — no itemized claim needed.
Cash Benefit Paid to You
The supplemental carrier pays the benefit directly to you — not to Medicare, not to the hospital. You use the cash however you need: medical bills, living expenses, or anything else.
The key difference from Medigap: Medigap coordinates directly with Medicare and pays specific cost-sharing amounts on your behalf. Supplemental products like cancer and hospital indemnity pay you a fixed benefit or lump sum — they don't coordinate with Medicare at all. This means they can stack with Medigap or Medicare Advantage, and the benefit is yours to use without any network or provider restrictions.
With vs. Without Supplemental Coverage
These are illustrative scenarios, not guarantees — but they show the financial difference supplemental coverage can make during major health events.
A note on the "without" figures below: the deductible and coinsurance amounts shown apply if you're on Original Medicare alone or Medicare Advantage. If you have Medigap (especially Plan G), most of that specific deductible and coinsurance is already covered — for you, these cash benefits are more about covering what Medigap doesn't reach: lost income, non-medical costs, transportation, or a specialized treatment your plan doesn't cover at all.
Stage II Breast Cancer Diagnosis — Chemotherapy + Surgery
A multi-month course of chemotherapy generates ongoing Part B coinsurance, on top of a Part A deductible for any related surgery, and potentially skilled nursing or home health costs. A cancer policy paying a lump-sum benefit at diagnosis is designed to help offset exposure like this — plus any income lost during treatment.
Heart Attack — Emergency Hospitalization + Cardiac Rehab
A heart attack resulting in a multi-day hospitalization, followed by weeks of outpatient cardiac rehabilitation. The Part A deductible applies to the hospital stay, and cardiac rehab under Part B generates its own coinsurance. A heart attack policy paying a lump sum at diagnosis is designed to offset the deductible, the rehab coinsurance, and a portion of any lost income during recovery.
Hip Fracture from a Fall — Surgery + Skilled Nursing Facility
Falls are the leading cause of injury-related hospitalization for Medicare beneficiaries. A hip fracture typically requires surgery (Part A deductible applies), followed by an extended stay in a skilled nursing facility, which carries its own daily coinsurance beyond the initial covered period. Hospital indemnity and accident coverage are designed to help offset costs like these.
All scenarios are illustrative concepts only, not cost estimates. Actual costs and benefits depend on individual plan terms, treatment details, provider charges, and geographic location. A PharmSurance advisor can walk through what applies to your specific situation. Not a guarantee of coverage amounts or out-of-pocket costs.
A Note on How These Products Are Presented
These are separate health insurance products regulated by state insurance law — not Medicare Advantage, Medigap, or Part D plans. Availability and underwriting vary by state and carrier; your advisor will confirm what's available to you. They're never presented as replacements for Medicare coverage — only as part of a complete picture of your protection. See the FAQ below for how Scope of Appointment rules apply to these products.
