Changes Medicare rules to improve access to mental health services by treating clinical social worker services differently under the Skilled Nursing Facility (SNF) prospective payment system and by clarifying which mental‑health and health‑and‑behavior services furnished by clinical social workers are included. The bill adds an explicit exclusion for clinical social worker services from certain SNF payment calculations and expands the statutory definition to name specific HCPCS codes for mental‑health and health‑and‑behavior services. The changes take effect for services furnished on or after January 1, 2026.
