CMS Finalizes Changes to Increasing Organ Transplant Access Model

Why It Matters

The changes tighten performance standards for transplant centers while expanding Medicare Advantage’s role in value‑based payments, reshaping financial risk and quality reporting across the kidney‑transplant ecosystem.

Key Takeaways

• Low-volume threshold raised from 11 to 15 kidney transplants annually
• Medicare Advantage patients now count toward IOTA upside/downside risk calculations
• Maximum upside‑risk payment stays at $15,000 per transplant
• Updated risk‑adjustment aligns with SRTR methodology for quality measure
• Patient notification rules added, but declined‑offer alerts not finalized

Pulse Analysis

The Centers for Medicare & Medicaid Services (CMS) finalized revisions to the Increasing Organ Transplant Access (IOTA) Model, a mandatory, six‑year program that began in July 2025 for kidney‑transplant hospitals. By raising the low‑volume benchmark to 15 transplants annually, CMS aims to concentrate resources on higher‑volume centers that can more consistently meet quality standards. The rule also integrates Medicare Advantage (MA) enrollees into the model’s financial risk calculations, reflecting the growing share of MA beneficiaries—projected to reach roughly 45 million by 2028—and ensuring that payment incentives align with the broader Medicare landscape.

For transplant hospitals, the adjustments carry tangible fiscal implications. Keeping the upside‑risk cap at $15,000 per transplant preserves a key revenue buffer that many facilities relied on when the original proposal suggested a $10,000 limit. Meanwhile, the adoption of a risk‑adjustment methodology consistent with the Scientific Registry of Transplant Recipients (SRTR) provides a more transparent and widely accepted metric for evaluating quality performance. Hospitals must now navigate stricter volume thresholds, incorporate MA patient data into their reporting, and meet new patient‑notification obligations, all of which could reshape operational workflows and budgeting strategies.

The broader industry sees these moves as a signal that CMS is balancing cost containment with quality assurance in a rapidly evolving Medicare market. Stakeholder feedback, notably from the American Hospital Association, influenced the decision to retain the higher upside‑risk payment and to pause the rollout of declined‑offer notifications. As MA enrollment expands, its inclusion in IOTA underscores a shift toward unified payment models that span traditional Medicare and private Medicare Advantage plans, potentially setting a precedent for other value‑based initiatives in specialty care.
