TennCare - As introduced, requires a managed care organization or pharmacy benefits manager that is contracted with the bureau to reimburse a claim for a long-acting injectable drug intended for treatment and prevention of human immunodeficiency virus and administered in a pharmacy, physician's office, clinic, ambulatory surgical treatment center, or hospital. - Amends TCA Title 4; Title 56 and Title 71.

SB 2499 requires TennCare-managed care organizations (MCOs) and pharmacy benefits managers (PBMs) to reimburse claims for long-acting injectable HIV treatment and prevention drugs administered in pharmacies, clinics, or medical facilities. This directly affects TennCare enrollees needing these drugs, MCOs/PBMs contracted with TennCare, and healthcare providers administering the treatments. The bill mandates single reimbursement for each treatment - either as a pharmacy benefit or medical service, but not both - to prevent duplicate payments. It applies specifically to covered HIV drugs administered in approved settings, ensuring consistent coverage under TennCare.
