How long does Medicare cover rehab?

Every family arriving in a skilled nursing facility hears the number one hundred. It sets an expectation that almost never matches what happens, and the gap between the two is where most of the distress lives.

What the hundred days actually means

Traditional Medicare covers up to 100 days of skilled nursing care per benefit period — the first twenty at no coinsurance, then a daily amount through day 100. The mechanics of that cost structure are worth reading once.

But the hundred is a maximum, not an entitlement. Coverage continues only while the patient still needs skilled care — nursing or therapy that legally requires a licensed professional. When that need resolves, coverage ends, whether it is day 14 or day 92.

Which is why the honest answer to how long will Medicare cover this? is that nobody can tell you on day one. It depends on progress, on medical stability, and on clinical judgment that has not been made yet.

Why does coverage end before day 100?

Three things end a stay, and only one of them is the calendar.

• The skilled need resolves. The wound closes, the medication regimen stabilises, the patient reaches their therapy goals. This is the good version, and it is the most common one.
• Progress stalls and the facility concludes skilled care is no longer required. This is the contested version, and it is where appeals belong.
• The hundred days run out. Genuinely uncommon.

The second is the one worth understanding in advance, because it is a judgment call — and judgment calls can be reviewed.

What is a NOMNC?

Before Medicare-covered services end, the facility must give written notice. It is a standard federal form called the Notice of Medicare Non-Coverage, and CMS requires that it be delivered at least two calendar days before covered services end.

It states the last day Medicare will pay, and it explains how to request an expedited review from an independent organisation — a Beneficiary and Family Centered Care Quality Improvement Organization, the BFCC-QIO. The contact details and the exact deadline are printed on the form.

That is the sheet to find and read carefully rather than sign and file. It is the difference between a decision that happened to you and a decision you can contest.

How do you appeal when coverage ends?

1. Call the number on the notice

   The BFCC-QIO for your state is printed on the NOMNC, along with the exact date and time by which you must call. That deadline is the one that governs — read it off the form rather than working from a general rule, because published summaries of it disagree. Call as early in the window as you can.

2. Ask the facility for the detailed explanation

   Once you request the review, the facility must issue a Detailed Explanation of Non-Coverage. This is where their specific clinical reasoning appears — and it is only produced because you appealed.

3. Get the clinical record moving

   Therapy notes, nursing notes, and physician documentation are what the reviewer weighs. The treating physician can submit support, and their input carries weight.

4. Make the maintenance argument if it applies

   If the reason given is that the patient has plateaued, that is not the legal standard. Skilled care may be covered to maintain a condition or slow decline, not only to improve it.

5. Keep every date and case number

   If the expedited review goes against you, further levels of appeal exist. A clean record of what was filed and when makes the next step far easier.

What if the appeal is denied?

Expedited reviews are decided quickly — that is the point of them — so an answer usually arrives within a day or two rather than weeks.

If the reviewer agrees with the facility, Medicare coverage ends on the date stated in the notice. Ask the reviewing organisation and the facility directly about liability for the days that elapsed during the review — that depends on the outcome and on when the appeal was filed, and it should be spelled out rather than assumed.

A denial at this stage is not the end of the road. The expedited review is the first level, and further levels of appeal exist beyond it. They move more slowly, which is exactly why the clean record from step five matters.

Practically, the situation usually resolves in one of four directions: staying at the facility as a private payer, applying for Medicaid if the person is likely to qualify, going home with home health services, or going home with family support. Which is realistic depends on finances, on the home, and on who is available — and it is a conversation to start with the facility's social worker before the decision arrives, not after.

One thing worth saying plainly: a denial does not mean the care was unnecessary or that anyone did anything wrong. It means a reviewer read the same record and reached a different conclusion about whether skilled care is still required. Those are genuinely close calls, which is why the review exists at all.

What to do the day the notice arrives

1. Read the last covered date and the appeal deadline. Both are on the form.
2. Decide quickly — the window is measured in hours, not days.
3. If in any doubt, call the QIO. The review is free and filing does not obligate you to anything.
4. Ask the facility what specifically changed in the clinical picture.
5. Contact your State Health Insurance Assistance Program. Free, unbiased, and they do this daily.

An appeal is not an accusation. Facilities issue these notices as a matter of routine, and a reviewer disagreeing is a normal outcome rather than a scandal. The only thing that guarantees the decision stands is not contesting it.
