What New Federal Reports Reveal About Medicare Advantage Denials — And Why It Matters for Seniors

If you or a loved one has ever needed skilled nursing care after a hospital stay, you know how stressful the approval process can be. Two new federal watchdog reports, released in June 2026, put hard numbers behind a concern that nursing home providers have raised for years: large Medicare Advantage insurers are denying care at unusually high rates — and reversing many of those denials only after enrollees fight back.

Here's a plain-language breakdown of what the reports found, why it matters, and where to go if you want to dig into the details yourself.

1. Two reports, one troubling pattern

The Department of Health and Human Services' Office of Inspector General (OIG) — an independent government watchdog — published two separate reports last week. One focused on skilled nursing facility (SNF) admissions. The other looked at long-term acute care and inpatient rehabilitation. Both reports reached a similar conclusion: the largest Medicare Advantage Organizations (MAOs) are denying post-acute care requests at rates far above what's typical for other types of care.

What this means: This isn't a single insurer's isolated policy or a one-off news story — it's a pattern confirmed by two independent federal analyses, which makes the findings harder to dismiss as a fluke.

2. The denial gap: 40% vs. 11%

The headline number is stark: MAOs denied 40 percent of requests for skilled nursing-level care, compared to just 11 percent for all other types of care requests.

What this means: Patients seeking nursing home or rehab care after a hospital stay are nearly four times more likely to be turned down than patients requesting other kinds of care. That's a significant, targeted gap — not just general strictness across the board.

3. When people appeal, they usually win — but few appeal at all

Only 18 percent of denied SNF requests were ever appealed. Of those that were, 95 percent were overturned in the enrollee's favor.

What this means: The vast majority of people who push back on a denial get the care they originally asked for — strongly suggesting many initial denials weren't medically justified in the first place. But the low appeal rate (under 1 in 5) also raises a quieter concern: how many people simply didn't have the time, knowledge, or support to fight a denial they should have won?

4. Winning an appeal still costs precious time

Even when enrollees appealed and won, they waited an average of six days for a decision, and 17 percent waited 10 days or more.

What this means: For a senior recovering from surgery or a serious illness, a six-to-ten-day delay isn't just paperwork — it can mean staying in a hospital bed longer than necessary or missing the critical early window for rehabilitation, both of which can affect long-term recovery.

5. One contractor stood out: naviHealth

The report singled out naviHealth (a subsidiary of UnitedHealth Group) as processing about half of all SNF admission requests industry-wide. Its denial rate was notably higher than both internal MAO reviews and other contractors, and when its denials were appealed, they were overturned 97 percent of the time.

What this means: A huge share of these decisions run through a small number of companies. When one contractor handles that much volume and its denials are reversed almost every time they're challenged, it points to a systemic process issue rather than a scattering of individual case-by-case judgment calls.

6. Not every Medicare Advantage plan works this way

The reports and AHCA/NCAL's response are careful to note that smaller, provider-led plans — called Institutional Special Needs Plans (I-SNPs) — tend to make care decisions collaboratively with the patient, their doctors, and their family. These plans have been associated with better care coordination and outcomes.

What this means: The problem isn't "Medicare Advantage" as a concept — it's specifically tied to how the largest, insurer-run plans structure their approval processes. Plan size and structure seem to matter a lot here.

7. What's being proposed to fix it

The American Health Care Association and National Center for Assisted Living (AHCA/NCAL) — the industry group representing nursing homes and assisted living providers — is using these findings to support the Medicare Advantage Improvement Act of 2026, legislation aimed at addressing prior authorization rules, prompt payment requirements, payment clawbacks, and transparency.

What this means: This isn't just a research finding sitting on a shelf — it's actively being used to push for policy change in Congress. Worth watching if you care about how this issue develops.

Why this matters, even if you're not dealing with it right now

Medicare Advantage now covers more than half of all Medicare beneficiaries, and skilled nursing needs become more common as people age. Understanding how these plans handle (or mishandle) post-acute care approvals is useful before a crisis hits — whether you're planning for your own future care, helping a parent navigate a hospital discharge, or working in the senior care field.

Take action: review the bill and make your voice heard

These reports are already shaping policy — the Medicare Advantage Improvement Act of 2026 (H.R. 8375 / S. 4384) is a bipartisan bill currently in Congress that would require faster prior authorization decisions (72 hours standard, 24 hours expedited), require medical necessity decisions to be made by qualified clinicians, and speed up claims payments to providers.

Here's how to get involved:

1. Review the bill yourself. Read a plain-language summary of what it does in AHCA/NCAL's overview of the bill's key provisions, or read the full bill text on Congress.gov.

2. If you think something's missing or should be changed, reach out directly to the bill's authors: Rep. John Joyce (R-PA), Sen. Roger Marshall (R-KS), or Rep. Jimmy Panetta (D-CA). They're the ones actively shaping the bill's language right now, and constituent and stakeholder feedback can influence amendments before it moves further.

3. If you think the bill covers the right ground as written, contact your own senators and representative and ask them to support it. You can find and message your legislators through house.gov's "Find Your Representative" tool and the U.S. Senate's contact directory.

Whether you want to push for changes or push for passage, the bill is still early in the legislative process — this is the window when input carries the most weight.
