Your mother’s discharge nurse tells you at 4 p.m. that she is leaving the hospital at 11 a.m. tomorrow, and the earliest anyone in your family can get a home health aide through the door is Friday. The discharge planner is polite but firm: the bed is needed, the doctor signed off this morning, and there is a folder of paperwork waiting for a signature. Nobody has mentioned that a form sitting in your mother’s chart since the day she was admitted gives her a way to pause that clock tonight, for free, before she leaves the building.

The moment the clock starts

Every hospital that admits a Medicare patient has to hand over a form called the Important Message from Medicare (IMM) within 2 calendar days of admission, under the federal rule that governs hospital discharge appeals, 42 CFR 405.1205. It explains, in plain language, that your mother has the right to appeal a discharge she is not ready for, and it prints the phone number for her region’s Quality Improvement Organization (QIO), the outside medical reviewer Medicare pays to referee exactly this kind of disagreement. The hospital also has to hand her a second, follow-up copy of that same form no more than 2 calendar days before the actual discharge date, which is usually within a day or so of whatever date the discharge planner just gave you.

That follow-up copy is the one that matters right now. If nobody can find it, ask the nurse’s station directly. It should already be in the room, signed near admission, with the QIO’s name and phone number printed on the front.

What has to happen before she leaves the building

1. Find the signed IMM in the discharge folder, or ask the nurse’s station for a copy if it is not in the room.
2. Call the Quality Improvement Organization number printed on that form. You can do this by phone, any day of the week, and the appeal starts the moment someone answers or you leave a message.
3. Do this before your mother is discharged. Federal rule sets the deadline as the planned discharge date itself, not the day after, so tonight, not tomorrow after she is already home, is what protects the bed.
4. Tell the discharge planner directly that you are appealing. A hospital cannot discharge around an active, timely appeal.
5. Expect a callback with a detailed written explanation of why the hospital believes she is ready. You are entitled to it once the reviewer notifies the hospital that an appeal has been filed.

The programs that activate the moment you call

Two mechanisms do the actual work here, and both trace back to the same federal appeal process: the Important Message from Medicare gives your mother notice of the right, and the fast appeal to the Quality Improvement Organization is how she uses it. Both are set up by the Centers for Medicare & Medicaid Services (CMS), the federal agency that runs Medicare and writes these appeal rules. The table below lays out every deadline in order, each tied to the exact regulation or form that sets it.

Event	Deadline	Source
Hospital delivers the Important Message from Medicare	Within 2 calendar days of admission	42 CFR 405.1205(b)(1)
Hospital delivers the follow-up copy	No more than 2 calendar days before discharge	42 CFR 405.1205(c)(1)
Family calls the QIO to request a fast appeal	No later than the planned discharge date, before leaving the hospital	42 CFR 405.1206(b)(1)
QIO issues its decision	Within 1 calendar day of receiving all requested records	42 CFR 405.1206(d)(6)(i)
Medicare coverage if the QIO sides with the hospital	Continues through noon the day after the QIO’s decision	42 CFR 405.1206(f)(2); CMS Important Message form

Notice what is not on that table: a deadline the day after discharge. The rule that actually controls the family’s decision is the planned discharge date itself. The “noon the next day” language people sometimes hear applies to how long Medicare keeps paying once the reviewer has already ruled, not to when you have to make the call.

The mistakes that close this window

Signing the discharge instructions does not waive the right to appeal, but treating that stack of paperwork as the actual moment of discharge is what makes families miss the window. The deadline is the calendar date on the discharge order, not the walk out the door, so a folder full of signatures the night before changes nothing if the call to the reviewer never happens.

Waiting to “see how tomorrow morning goes” before calling is the second version of the same mistake. The reviewer’s phone line takes calls every day of the week, including tonight, and the appeal begins the moment someone picks up.

If your mother has a Medicare Advantage plan instead of Original Medicare, the same fast-appeal right exists, but the number to call is different. Check her insurance card first: Medicare Advantage members call their own plan, not the regional Quality Improvement Organization, and the plan is held to the same fast timeline.

Some families also assume the hospital will retaliate, that the appeal has a cost, or that a caseworker or attorney has to file it. None of that is true. The form exists precisely so a family member can make the call directly.

What happens after the QIO decides

If the reviewer agrees your mother is not ready, Medicare keeps covering the stay and no new bill shows up for the extra days. If the reviewer sides with the hospital instead, coverage still runs through noon the day after that decision arrives, which is normally enough time to arrange transportation, get a nursing home’s paperwork signed, or have a home health order faxed over. A first-level loss is not the end, either: a written request to Medicare’s next reviewer, called reconsideration, is due by noon the following calendar day, so new medical information can still change the outcome.

What happens next depends on where she is actually headed. If the plan is a skilled nursing facility, the days this appeal buys you are worth spending on confirming the hospital stay itself qualifies her for that coverage in the first place, which is its own separate clock covered in what the 3-day hospital stay rule actually requires before Medicare pays for a nursing home bed. If she is headed to inpatient rehab instead and the holdup becomes an insurance company that has not signed off yet, that is a different appeal entirely, one this family may be facing within days, walked through in what to do when a rehab discharge outruns your insurer’s approval.

Frequently asked questions

What if we miss the same-day deadline to call? You still have options. A beneficiary who misses the same-day window but is still in the hospital can request review at any time during the stay, and one who has already gone home can request it within 30 calendar days of discharge. The financial protection that pauses billing while you wait no longer applies in either case.

Does the fast appeal cost anything? No. If you call by the deadline, your mother owes only her normal Medicare copays and deductibles while the reviewer decides, not a self-pay day rate for the extra time in the hospital. The appeal itself carries no fee and requires no attorney.

What if she has a Medicare Advantage plan instead of Original Medicare? The right to a fast appeal is the same, but the phone number is different. Call the Medicare Advantage plan listed on her insurance card instead of the regional Quality Improvement Organization, and the plan must follow the same one-day decision clock.

What does the hospital owe us once we call? A detailed written notice explaining exactly why the hospital believes she is ready for discharge, including the specific medical reasoning. It has to reach your family quickly once the reviewer tells the hospital an appeal is underway, so everyone is arguing from the same facts.

Can the hospital bill us while the appeal is pending? Not if the call was made by the deadline. Medicare, or her Medicare Advantage plan, keeps paying through the reviewer’s decision, and coverage continues through noon the following day even if that decision favors the hospital.
