Notice 2025-12, page 813.

This notice provides the indexing factors to be used by group health plans and health insurance issuers to calculate the qualifying payment amount (QPA) for items or services provided on or after January 1, 2025, and before January 1, 2026. The QPA is the basis for determining individual cost sharing for items and services covered by the balance-billing protections in the NSA, under certain circumstances. The QPA for a given calendar year is based on information regarding median rates for certain items and services from prior years and is indexed based on changes in the consumer price index. In addition to providing the indexing factor for adjusting 2024 amounts for 2025, the notice also provides cumulative adjustments for prior years.
