Extends and expands a federal rule that requires Medicaid to pay certain primary care services at least as much as Medicare Part B (or a higher 2009‑based floor where specified). It broadens which clinicians qualify for that payment floor, clarifies which services count as primary care (excluding emergency department care), and obligates Medicaid managed‑care contracts to ensure and document these higher payments. The law also directs HHS to run a state‑by‑state study comparing Medicaid enrollment, provider counts, and primary‑care payment rates (with $200,000 authorized for FY2026) and expresses congressional support for following the American Academy of Pediatrics’ Bright Futures guidelines for pediatric preventive care.

The changes include retroactive and forward‑looking timing: some payment provisions reference services from 2013–2014, while other requirements start the first month after enactment or on the enactment date for newly executed managed‑care contracts. The measure affects Medicaid beneficiaries, primary‑care clinicians, state Medicaid programs, and managed‑care plans by raising minimum payment levels and requiring documentation and oversight of compliance, while HHS will produce a funded study to track enrollment, providers, and payments by state.
