26 CFR 1.401(l)-1: Permitted disparity in employer-provided contributions or benefits

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, 2024, and before January 1, 2025. The No Surprises Act (NSA) added parallel provisions at Code sections 9816 and 9817, ERISA sections 716 and 717, and PHS Act sections 2799A-1 and 2799A-2. These provisions provide protections against balance-billing for certain out-of-network items or services provided to patients. 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 2023 amounts for 2024, the notice also provides cumulative adjustments for prior years and examples of how to apply the percentage increases.
