Does Medigap Cover Long-Term Care?

If your parent has a Medigap (Medicare Supplement) policy, you might assume the long-term care bills are handled. They're not — Medigap does not cover long-term custodial care, assisted living, memory care, or extended nursing home stays. But writing the policy off entirely would be a mistake: Medigap covers the most expensive gap in Medicare's short-term coverage, and in 2026 that gap is worth up to $17,360 per benefit period.

What Medigap is — and isn't

Medigap policies are private insurance standardized into lettered plans (G, N, and others) that pay the deductibles and coinsurance Original Medicare leaves behind. They supplement Medicare; they don't extend it. The governing rule: Medigap pays only when Medicare pays. When Medicare coverage ends — because the 100 days ran out or because care became custodial — Medigap ends with it.

Long-term care, in the sense families mean it — months or years of help with bathing, dressing, eating, and supervision — is custodial care. Medicare never covers it, so Medigap never covers it either. No lettered plan changes this; it's structural, not a matter of picking a better plan.

What Medigap does cover: the SNF coinsurance

The valuable coverage is in the skilled nursing facility benefit. After a qualifying three-midnight inpatient hospital stay, Medicare covers up to 100 days of SNF rehab per benefit period, but with cost-sharing:

• Days 1–20: $0 (Medicare covers fully)
• Days 21–100: $217/day coinsurance in 2026 — the beneficiary's responsibility
• A full 100-day stay: 80 days × $217 = $17,360 out of pocket

Most standardized Medigap plans — including the popular Plan G and Plan N — cover that SNF coinsurance in full. On Original Medicare alone, a parent who needs 80 days of rehab generates a five-figure bill; with Medigap, the family cost for the covered stay is effectively $0. Medigap plans also cover the Part A hospital deductible ($1,736 per benefit period in 2026) and add 365 extra lifetime hospital days beyond Medicare's limits.

That's the honest summary: Medigap is excellent insurance for the rehab phase of a care crisis and worthless for the custodial phase that follows.

The day-101 reality

Medicare — with or without Medigap — pays nothing after day 100 in a benefit period, and nothing at any point once care is classified as custodial. A parent who transitions from rehab to long-term nursing home residency faces the full private rate: $7,500 to $16,000+ per month depending on region and room type (national private-room median around $10,800). Medigap makes no contribution to any of it.

The funding sources for that phase are entirely different:

• Medicaid — the primary payer of long-term nursing home care, once strict asset (~$2,000 in most states) and clinical criteria are met
• Long-term care insurance — a separate product sold precisely for this; pays a daily benefit after an elimination period, usually 90 days
• VA Aid and Attendance — for wartime veterans and surviving spouses; up to $2,424/month (single veteran, 2026)
• Private funds — income, savings, home equity

Should your parent keep paying the Medigap premium?

A real question families ask when money gets tight: if Medigap doesn't cover long-term care, why keep it? The answer depends on where your parent is in the care trajectory.

• Still living independently or in early decline: keep it. One hospitalization plus 60 days of rehab would cost more than years of premiums. Dropping Medigap also generally means losing guaranteed-issue status — getting back in later requires medical underwriting and can be denied.
• Already in long-term custodial care on Medicaid: the calculation changes. Medicaid becomes the effective supplemental coverage — it picks up Medicare cost-sharing for dual-eligibles — and the Medigap premium may be money better redirected to care costs. But cancel deliberately, not by letting the policy lapse, and check whether the state requires keeping it (some Medicaid programs actually pay the premium when it's cost-effective).
• In rehab now, heading toward Medicaid: keep it through the covered stay. The coinsurance it's paying right now is the point of the policy.

The bottom line

Does Medigap cover long-term care? No — and no supplemental plan does, because Medigap only fills gaps inside Medicare's coverage, and Medicare's coverage ends where custodial care begins. What Medigap does is eliminate the expensive middle: the $1,736 hospital deductible and the $217-a-day rehab coinsurance that would otherwise hit during the weeks when a family is making its biggest decisions.
