What to do if your over 100 days of Skilled Nursing Care?

Short answer: No — there is no rule that requires a skilled nursing facility (SNF) to charge the Medicare rate after day 100. After Medicare coverage ends, the facility can generally charge its normal private-pay rate, unless another payer (Medicaid/Medi-Cal, long-term-care insurance, etc.) applies.

What Medicare actually requires

Under Medicare Part A, SNF coverage is limited to 100 days per benefit period if the patient qualifies (e.g., after a 3-day inpatient hospital stay). (Aetna)

Cost structure:

• Days 1–20: Medicare pays the full covered amount.

• Days 21–100: Medicare pays most of the cost; the patient pays a daily coinsurance.

• After day 100: Medicare stops paying entirely. (Solace)

Once that limit is reached:

“After 100 days, Medicare stops covering SNF care… you are fully responsible for all costs associated with continued care.” (Clara Home Care)

So the facility is not limited to the Medicare reimbursement rate after day 100; the resident becomes private pay unless another program covers the stay.

Why the “Medicare rate after 100 days” myth sometimes circulates

The confusion often comes from a few related rules:

1. Medicaid / Medi-Cal rules:
   If a patient transitions to Medicaid (e.g., Medi-Cal long-term care), the facility must accept the Medicaid rate, which is usually much lower than private pay.

2. Medicare-certified facilities:
   While under Medicare coverage, they must accept the Medicare-approved payment as full payment for covered services.

3. Medigap policies:
   Some Medigap plans pay the daily coinsurance for days 21-100, which can make it appear that Medicare pricing continues longer.

But none of these require the SNF to keep charging the Medicare rate after day 100 if the patient stays privately.

Good primary citation

A clear government source is:

• Medicare.gov — Skilled Nursing Facility Care
  “Part A limits SNF coverage to 100 days in each benefit period.” (Medicare)

After those days, the beneficiary must pay the cost themselves.

✅ Bottom line:

• Medicare pays up to 100 days of SNF care per benefit period.

• After day 100, Medicare pays nothing, and the facility can generally charge its regular private-pay rate, not the Medicare rate.

If you’d like, Steve, I can also show you one obscure Medicare rule that sometimes helps people extend SNF coverage past 100 days indirectly (it’s a strategy used by elder-law attorneys and discharge planners).

The “60-Day Break” Rule (Benefit Period Reset)

Under Medicare Part A, the 100-day SNF limit applies per benefit period, not per year.

A benefit period ends when the patient has gone 60 consecutive days without:

• inpatient hospital care, and

• skilled nursing facility care.

Once that happens, a new benefit period begins, and the person can qualify for another 100 SNF days if the other conditions are met.

Citation

• Centers for Medicare & Medicaid Services — Medicare & You handbook:

“A benefit period ends when you haven’t gotten any inpatient hospital care (or skilled care in a SNF) for 60 days in a row. If you go into a hospital or SNF after one benefit period has ended, a new benefit period begins.”

Source: Medicare & You 2026, Skilled Nursing Facility section.

How the “Reset” Strategy Works in Real Life

A typical scenario:

1. Patient receives 100 days of Medicare SNF care.

2. They are discharged to:

   • home,

   • assisted living, or

   • custodial nursing care (non-skilled).

3. 60 days pass with no hospital or skilled SNF care.

4. Patient later has a new hospital admission (3-day inpatient stay).

5. They again qualify for up to 100 SNF days.

So theoretically someone could have multiple SNF benefit periods in one year if the timing works.

The Catch (Important)

To qualify again, the person must still meet all SNF requirements:

1. 3-day inpatient hospital stay (observation days don’t count).

2. Need skilled care (rehab, IV therapy, wound care, etc.).

3. Admission to SNF within 30 days of hospital discharge.

Citation:

• Centers for Medicare & Medicaid Services — Medicare SNF coverage rules (42 CFR §409.30).

Another Little-Known Rule

Sometimes facilities use the “skilled therapy requirement” interpretation:

If a patient still needs daily skilled therapy or nursing, Medicare may continue coverage within the 100 days even if improvement is slow or plateauing.

This came from the Jimmo v. Sebelius settlement, which clarified:

Medicare coverage does not require improvement, only the need for skilled care to maintain condition or prevent deterioration.

That ruling is extremely important in SNF appeals.

✅ Practical takeaway for your clients

For Medicare beneficiaries:

• SNF coverage = up to 100 days per benefit period

• Benefit period resets after 60 days without hospital/SNF care

• A new hospital stay can trigger another 100-day cycle

If you want, I can also show you the nursing-home billing rule that actually does limit what they can charge in certain situations.

It’s obscure and very relevant to Medi-Cal / Medicaid patients in California, and it might have been what you originally heard about.

Steve, the rule you’re probably thinking about is the “bed-hold / leave day” and “no balance billing” framework for Medicare-certified nursing facilities. It doesn’t extend Medicare coverage, but it does restrict what facilities can charge in certain situations, which is why people sometimes think the facility must keep using the Medicare rate.

1. The “No Balance Billing” Rule While Medicare Is Paying

If a resident is in a Medicare-covered SNF stay, the facility must accept the Medicare payment plus any required coinsurance as full payment for covered services.

They cannot charge additional fees for services that are included in the SNF per-diem payment.

Citation

• Centers for Medicare & Medicaid Services — Medicare Benefit Policy Manual, Ch. 8 §10

“The SNF must accept the Medicare payment as payment in full for covered services.”

This means a facility cannot bill extra “retail” charges for services included in the SNF benefit.

2. The “Leave Day / Bed-Hold” Rules

When a resident temporarily leaves a nursing facility (for example, hospital transfer or therapeutic leave), the facility sometimes cannot charge the resident privately for the bed during Medicare coverage.

These rules mostly arise from state Medicaid law and federal nursing-home regulations.

Citation:

• Centers for Medicare & Medicaid Services — Nursing Facility Requirements
  42 CFR §483.15

Facilities must clearly disclose bed-hold policies and cannot impose charges inconsistent with Medicare or Medicaid payment rules.

3. The Rule That Actually Limits Charges (Medicaid)

The strongest restriction is actually the Medicaid payment-in-full rule:

• If the resident is Medicaid-eligible,

• and the facility participates in Medicaid,

the facility must accept the Medicaid rate as full payment and cannot bill the resident extra.

Citation:

• Centers for Medicare & Medicaid Services — 42 CFR §483.15(e)

“The facility must accept the Medicaid payment as payment in full.”

Why the Confusion Happens

Families often see something like this timeline:

1. Hospital stay

2. Medicare SNF coverage (up to 100 days)

3. Patient becomes Medicaid eligible

4. Facility switches from private pay rate ($10k–$15k/month) to Medicaid rate ($6k–$9k/month)

So it appears as though “the nursing home had to charge the Medicare rate after day 100.”

But in reality the change happened because Medicaid eligibility started.

Bottom Line

• Medicare SNF coverage: 100 days max per benefit period

• After day 100: facility may charge its private-pay rate

• If Medicaid starts: facility must accept the Medicaid rate as full payment

💡 One last thing, Steve — because you work with Medicare clients, there is actually a frequently misunderstood SNF billing protection that can matter for beneficiaries with Medigap policies.

It relates to who is responsible if Medicare later denies a SNF claim after the patient was already admitted. The rule can prevent the patient from being billed thousands of dollars. If you want, I can show you that one too.
