What to Do After a Medicare Advantage Denial for Skilled Nursing or Rehab: A Fast, Step-by-Step Checklist
On a Tuesday afternoon, a nurse wheels in a clipboard and a sentence that changes the room’s temperature.
“Your Medicare Advantage coverage for rehab ends Friday.”
For many families, this is how a skilled nursing facility (SNF) stay, or an inpatient rehabilitation facility (IRF) course gets cut short: not with a physician’s discharge order, but with a coverage decision. Medicare Advantage (MA) plans now cover more than half of Medicare beneficiaries, and disputes over “post-acute care” like skilled nursing and rehabilitation have become a recurring flashpoint. In 2024, the U.S. Senate Permanent Subcommittee on Investigations described how some Medicare Advantage plans used prior authorization and internal rules to delay or deny care, including post-acute services.
This article is a practical playbook. It is written for patients and families facing a Medicare Advantage denial for skilled nursing or rehab and asking the only question that matters in the moment: What do we do next, step by step, and how fast?
First, identify the kind of denial you are dealing with
Medicare Advantage denials in skilled nursing and rehab usually fall into two lanes, and the “right” appeal path depends on which lane you are in.
Lane 1: A denial of coverage for services (often tied to prior authorization)
Examples:
- “We will not authorize admission to a skilled nursing facility.”
- “We will not approve additional days of rehab.”
- “We will reduce or discontinue the level of care for a previously authorized course of treatment.”
These decisions are usually handled through an organization determination under Medicare Advantage rules.
Lane 2: A notice that coverage is ending soon, while you are already in a facility
Examples:
- “Coverage ends in two days.”
- “Your stay is no longer medically necessary.”
Medicare Advantage rules require special termination notice protections for services furnished by a skilled nursing facility (SNF), home health agency, comprehensive outpatient rehabilitation facility (CORF), or hospice. These cases can trigger a faster, “fast-track” style appeal timeline.
If you take only one thing from this article, take this: the fastest appeal options often depend on acting immediately and choosing the correct lane.
The clock matters, and Medicare Advantage rules are built around clocks.
A Medicare Advantage plan generally must decide on a standard organization determination request within 14 calendar days after receiving the request. The plan may extend the timeframe by up to 14 additional days only in limited circumstances (including when it is in the enrollee’s interest), and it must give written notice explaining the delay and the right to file an expedited grievance about the extension.
When delay could seriously jeopardize health, beneficiaries can seek expedited review, which is designed to move in hours and days, not weeks.
This is not an academic point. In skilled nursing or rehab, time is often the difference between safe discharge and a dangerous one.
Step-by-step playbook: How to appeal a Medicare Advantage skilled nursing or rehab denial
Step 1: Gather the “core record” in one place (same day, if possible)
Before you call anyone, build a small packet. It should be short enough to fax or upload quickly and strong enough for a medical reviewer to understand the case without having to guess.
Core record checklist:
- The denial notice (every page)
- The current plan of care (therapy frequency, goals, objective progress)
- Most recent therapy notes (physical therapy (PT), occupational therapy (OT), speech therapy (ST), as applicable)
- Nursing notes showing skilled needs (wound care, injections, monitoring, complex medication management)
- Treating physician’s note explaining why the level of care remains medically necessary
- A discharge risk summary: what happens if the patient goes home today (falls, inability to transfer, inability to ambulate, caregiver limitations)
Why this matters: Medicare Advantage appeals are frequently won or lost on the paper record. The plan’s own regulations require written notices stating specific reasons for a denial and explaining appeal rights. Your job is to build a counter-record that is equally specific.
Step 2: File the request in the correct posture: organization determination (OD) or fast termination appeal
If you are in Lane 1 (denial of coverage or denial of additional days)
File (or have a provider file) an organization determination request.
Medicare Advantage rules allow a provider, including a contracted provider, to request an organization determination and permit requests in multiple ways, including orally or in writing, depending on the situation.
Request an expedited review if the delay harms the patient. Medicare Advantage rules require the plan to decide whether to expedite “as expeditiously as the enrollee’s health requires” and generally no later than 72 hours after receiving the request.
A critical enforcement hook: if the plan fails to meet the expedited timeframe, that failure can be treated as an adverse determination and becomes appealable.
If you are in Lane 2 (coverage termination while in an SNF or specific rehab settings)
Check whether the notice is a termination notice involving a skilled nursing facility (SNF), home health, comprehensive outpatient rehabilitation facility (CORF), or hospice. Medicare Advantage regulations require the plan to notify the enrollee at least two days before termination and to include information about appeal rights, how to obtain an expedited determination, and what will happen to payments if the appeal is unfavorable.
This is often where speed becomes life-or-decline. The independent entity’s decision on an expedited determination must generally be made by the close of business the day after it receives all information needed to make the decision.
Step 3: If you get an adverse decision, file a reconsideration quickly and correctly
A Medicare Advantage appeal usually moves from the plan’s decision to a reconsideration.
File within the deadline
A request for reconsideration generally must be filed within 60 calendar days after receipt of the written organization determination notice, with a presumption that receipt occurs five calendar days after the date of the notice unless evidence shows otherwise.
If you missed the deadline, there may be an extension for good cause, but do not assume there will be one. File and explain.
Request expedited reconsideration when the patient cannot wait
If the plan approves expedited reconsideration, it must complete it and provide notice generally within 72 hours after receiving the request.
Demand a qualified medical reviewer for medical necessity denials
When the issue is denial of coverage based on lack of medical necessity (or a substantively equivalent term), the reconsidered determination must be made by a physician with appropriate expertise.
This is not a magic phrase, but it is leverage. If the plan’s denial reads like a template, you want to force the case back into individualized medical review.
Know what happens if the plan “runs out the clock.”
If the Medicare Advantage organization fails to meet specific expedited reconsideration timeframes, the failure can itself constitute an adverse determination, and the file must be sent to the independent entity within 24 hours after the timeframe expires.
That rule exists for a reason: delays can function like denials.
Step 4: Understand escalation to independent review and what winning actually means
When an adverse decision is affirmed, the case typically moves to review by an independent entity contracted by the Centers for Medicare and Medicaid Services (CMS).
If you prevail at an independent review or beyond, Medicare Advantage rules contain effectuation requirements, meaning the plan must authorize, provide, or pay for the disputed service within specified timelines (depending on what was denied and at what level you won).
Practical takeaway: When you win, press for implementation immediately. Bureaucracies sometimes move only when pushed.
The “why” behind many skilled nursing and rehab denials
Here is the uncomfortable truth: the denial often arrives dressed in medical language, but it can be driven by administrative machinery.
In 2024, the U.S. Department of Health and Human Services (HHS) Office of Inspector General (OIG) reported that Medicare Advantage prior authorization denials can delay or deny access to care, and it has continued to highlight concerns about inappropriate denials and barriers to care. MedPAC (the Medicare Payment Advisory Commission (MedPAC)) has also discussed how prior authorization and plan management tools can affect access and utilization in Medicare Advantage, including post-acute care.
None of that changes your immediate mission. But it does explain why your appeal needs to do more than argue. It needs to be documented.
What makes a skilled nursing or rehab appeal stronger
1) Replace conclusions with facts
Instead of: “Patient needs more rehab.”
Use: “Patient requires moderate assistance to transfer, cannot ambulate safely without hands-on support, and has documented fall risk. Discharge home would require 24-hour assistance that is not available.”
2) Write the appeal to the reviewer, not the slogan
Ask your facility and physician to anchor the appeal in:
- objective therapy measures (distance ambulated, assistance level, endurance)
- skilled nursing interventions (wound care, monitoring, injections)
- Why are lower levels of care unsafe now
3) Address the plan’s stated reasons, point by point
Medicare Advantage denial notices must state the specific reasons for denial and describe appeal rights, including the conditions for expedited reconsideration. Your appeal should mirror that structure.
4) If the plan used criteria, ask what criteria
CMS has moved toward more transparency around prior authorization decision-making and the information used to support those decisions. Even before broader reforms fully take effect, requesting the plan’s criteria and insisting on a record-based explanation can sharpen your appeal.
A simple Medicare Advantage SNF and rehab appeal timeline you can use today.
Use this as a quick reference. Then confirm details in your denial notice.
- Standard organization determination: generally within 14 calendar days, with limited extension rules.
- Expedited organization determination: decision generally within 72 hours after receiving the request (health permitting).
- Reconsideration request deadline: generally 60 calendar days after receipt of the written determination (receipt presumed 5 days after the notice date).
- Expedited reconsideration: generally within 72 hours after receiving the request.
- Termination notices for SNF and certain services: generally must be sent at least two days before termination and must include required appeal-right information.
- Fast-track style independent decision timing (for certain terminations): generally by close of business the day after receiving all needed information.
When to consider getting help
Some families can handle the early steps on their own. Others cannot, especially when the patient is medically fragile, and the facility is planning discharge.
Consider legal help if:
- The plan is pushing for discharge, and the patient is not safe to go home
- The denial is based on “not medically necessary” despite ongoing skilled needs
- You need an expedited review, and the plan is slow-walking
- The paperwork is inconsistent, unclear, or missing required information
- The facility is unsure how to trigger the fastest appeal lane
