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.

HB 2457 requires TennCare-managed care organizations (MCOs) and pharmacy benefits managers (PBMs) to reimburse claims for long-acting injectable HIV drugs used for both treatment and prevention. These drugs must be administered in settings like pharmacies, clinics, or hospitals, directly affecting TennCare enrollees with HIV. The bill mandates that MCOs/PBMs cover these drugs under either pharmacy or medical benefits but prohibits double reimbursement - providers can only be paid once per service. The law takes effect July 1, 2026, ensuring consistent coverage for this specific HIV care option.
