Four axes from current statute and agency guidance. Teal bar = substitution/assistance/access in place; amber = permissive or absent.
| Generic substitution mandate | Permissive |
| State Pharmaceutical Assistance Program | No broad SPAP |
| 90-day fills permitted | Allowed |
| PMP mandatory prescriber query | Required by statute |
Kentucky permits but does not mandate generic substitution. Under KRS § 217.822, a pharmacist may substitute a less expensive therapeutically equivalent drug product unless the prescriber has written "do not substitute" or "dispense as written." The substitute must be FDA AB-rated.
The Kentucky Cabinet for Health and Family Services maintains the Kentucky Medicaid Preferred Drug List. Most members are enrolled in Kentucky Medicaid managed-care plans (Anthem, Aetna, Humana, Passport, Wellcare, United), which follow the unified PDL. Non-preferred drugs require prior authorization.

Kentucky does not operate a Medicare-recognized SPAP. Low-income Kentuckians use Medicare Part D Extra Help (LIS), Kentucky Medicaid (if eligible), manufacturer Patient Assistance Programs, and SHIP (State Health Insurance Assistance Program) for Medicare enrollment counseling.
Eligibility: No active SPAP. Use Federal Extra Help and Medicaid.
Kentucky permits 90-day fills of non-controlled chronic medications. Out-of-state pharmacies must hold a Kentucky Nonresident Pharmacy permit. Federal CSA refill limits apply to controlled substances.
Kentucky operates KASPER, the Kentucky All Schedule Prescription Electronic Reporting system. Under KRS § 218A.172, prescribers must query KASPER before initially prescribing a Schedule II-III controlled substance and every three months during continued therapy. Dispensers must report Schedule II-V dispensing within one business day.
