The last time a plan denied or downgraded a post-acute discharge, the conversation probably stayed on the patient's clinical facts and the plan's criteria. That is where the appeal should stay. But MedPAC has now added national context that may help frame a more informed discussion.

At its September 4, 2026 public meeting, MedPAC presented initial findings from an analysis of acute-care-hospital and post-acute-care use among beneficiaries in fee-for-service Medicare and Medicare Advantage. The Commission said the work is intended to improve understanding of how beneficiaries in the two programs receive post-acute care and how differing program incentives may affect the amount and location of care.

In the home-health analysis, MedPAC reported that MA enrollees averaged 12 annual home-health visit-days, compared with 15 for FFS beneficiaries — a 20% difference. That result documents a utilization difference. It does not establish that MA plans are denying medically necessary care, that FFS utilization is excessive, or that a specific patient's requested level of care is appropriate. The clinical facts of the individual case remain decisive.

Why This Matters in a Peer-to-Peer

Case management and UR teams know the utilization gap anecdotally. Every advisor has seen the discharge that should have gone to IRF land in SNF, or the home health order that came back shorter than ordered. But anecdote does not move a peer-to-peer the way Commission data does.

MedPAC is not a regulatory body. Its analyses do not bind CMS, plans, or anyone else. But in a peer-to-peer conversation with a plan's medical director, "MedPAC's September 2026 preliminary analysis found lower average home-health utilization in MA than FFS and is examining what drives that difference" is a different sentence than "we see denials here more often than in traditional Medicare." The second statement describes your experience. The first places the conversation in a national analytical context — while remaining accurate about what the analysis does and does not prove.

The appropriate use in a peer-to-peer is therefore restrained: "MedPAC is actively examining lower observed MA post-acute-care use relative to FFS. In this patient's case, please explain how the proposed alternative meets the patient's documented functional, clinical, caregiver, and safety needs." That uses the Commission's analysis to ask for a patient-specific rationale rather than treating a population statistic as a substitute for one.

What the Commission Actually Debated

The presentation did not draw a single conclusion. Commissioners discussed competing interpretations of the observed utilization differences, including whether lower MA use reflects more efficient care management, restricted access, differences in enrolled populations, payment incentives, or some combination of these factors. The September session did not resolve those questions.

That is an important distinction. MedPAC is examining utilization patterns, not announcing that MA denials are unlawful, clinically inappropriate, or the sole cause of lower use. The strongest version of the argument for a peer-to-peer is: the data provide context for asking whether a plan's criteria, authorization processes, network design, or discharge-management practices systematically produce lower use than FFS — not proof that an individual denial lacks clinical justification.

Three Ways to Use This in Practice

In peer-to-peer reviews: Cite the MedPAC presentation (September 4, 2026, "Examining use of post-acute care services by beneficiaries in fee-for-service Medicare and Medicare Advantage") when asking the plan to explain how the proposed alternative meets the patient's specific documented needs. You are not claiming the plan acted illegally; you are placing the denial in a national analytical context the Commission is actively examining.

In network and contract conversations: If your organization is negotiating with a plan on PAC criteria or coverage arrangements, the MedPAC data provides a documented basis for the claim that MA and FFS populations show different utilization patterns — not as an accusation, but as a starting point for alignment on criteria that account for patient-specific clinical needs.

In documentation practices: Home health, SNF, and IRF are common post-acute settings in which utilization-management, service-authorization, discharge-planning, and coverage disputes can arise, although the applicable process varies by service, payer, and plan. Strong contemporaneous documentation now protects patients regardless of how the policy conversation evolves.

Watch Item

MedPAC's September session was early-cycle work. The Commission did not adopt a recommendation or resolve whether the observed utilization differences reflect care management, access barriers, selection, payment incentives, variation in provider practice, or a combination of those factors. MedPAC may continue the analysis and could consider a range of policy questions relating to PAC payment, access, care management, data collection, and MA oversight. No recommendation or policy direction was adopted at the September meeting.

The September 2026 meeting transcript is available at medpac.gov and is worth reading for the commissioner discussion rather than the staff presentation alone.
