Four axes from current statute and agency guidance. Teal bar = substitution/assistance/access in place; amber = permissive or absent.

Tennessee permits but does not mandate generic substitution. Under Tenn. Code Ann. § 53-10-204, a pharmacist may substitute a generically equivalent drug product unless the prescriber has indicated "dispense as written" or has signed in the appropriate non-substitution location. The substitute must be FDA AB-rated. The patient must be notified.
Tennessee Medicaid is operated as TennCare, an entirely managed-care Medicaid program. TennCare contracts with Managed Care Organizations (BlueCare, UnitedHealthcare Community Plan, Amerigroup, Wellpoint, TennCare Select) which administer pharmacy benefits using a unified TennCare PDL. Non-preferred drugs require prior authorization initiated by the prescriber.

Tennessee does not operate a Medicare-recognized SPAP. The state offers CoverRx, a discount-only program for uninsured Tennesseans not eligible for TennCare. Low-income Tennesseans use Medicare Part D Extra Help (LIS), TennCare Medicaid (if eligible), manufacturer Patient Assistance Programs, and SHIP (State Health Insurance Assistance Program) for Medicare enrollment counseling.
Eligibility: CoverRx is a discount card (not Medicare-creditable). No active broad SPAP.
Tennessee permits 90-day fills of non-controlled chronic medications at retail and mail-order pharmacies. Out-of-state pharmacies must hold a TN Nonresident Pharmacy license from the Board of Pharmacy. Tennessee requires e-prescribing for Schedule II-V controlled substances under Public Chapter 1039 (2018). Federal CSA refill limits apply.
Tennessee operates the Controlled Substance Monitoring Database (CSMD). Under Tenn. Code Ann. § 53-10-310, prescribers must check the CSMD before issuing the first prescription of a Schedule II-IV controlled substance and at least every six months during continued therapy. Dispensers must report Schedule II-V dispensing within seven days.
