Improving Access to Mental Health Act of 2023

This bill increases Medicare reimbursement for clinical social workers from 75% to 85% of the payment rate for psychologists under Part B. It also removes an exclusion that previously prevented skilled nursing facilities from billing Medicare for social worker services provided to residents. The bill expands covered services to include specific mental health assessments and interventions identified by HCPCS codes (like 96156, 96158-96161, etc.) for Medicare beneficiaries. These changes take effect for services provided on or after January 1, 2024, directly affecting Medicare patients and clinical social workers.
