Generic substitution law Verified 2026-05-23

Nevada permits but does not mandate generic substitution. Under NRS § 639.2581, a pharmacist may substitute a less expensive equivalent drug product unless the prescriber has indicated "dispense as written" or otherwise prohibited substitution. The substitute must be FDA AB-rated. Patient consent is required.

Medicaid formulary access Verified 2026-05-23

Nevada Medicaid maintains the Nevada Medicaid Preferred Drug List. Most members are enrolled in Nevada Check Up/Medicaid managed-care plans (Anthem, Health Plan of Nevada, Molina, SilverSummit), which follow the unified PDL. Non-preferred drugs require prior authorization initiated by the prescriber.

Prior authorization contact: Nevada Medicaid Pharmacy: 1-800-525-2395

State Pharmaceutical Assistance Verified 2026-05-23

Nevada does not operate a Medicare-recognized SPAP. Low-income Nevadans use Medicare Part D Extra Help (LIS), Nevada Medicaid (if eligible), manufacturer Patient Assistance Programs, and Nevada SHIP (State Health Insurance Assistance Program) for Medicare enrollment counseling.

Eligibility: No state SPAP. Nevada SHIP (State Health Insurance Assistance Program) helps with Medicare enrollment.

Dispensing rules: 90-day fills, mail order, refills Verified 2026-05-23

Nevada permits 90-day fills of non-controlled chronic medications at retail and mail-order pharmacies. Out-of-state pharmacies must hold a Nevada Nonresident Pharmacy license from the Board of Pharmacy. Federal CSA refill limits apply to controlled substances.

Prescription Monitoring Program Verified 2026-05-23

Nevada operates the Nevada Prescription Monitoring Program (NV PMP), under NRS § 453.1545. Prescribers must check the PMP before issuing certain controlled-substance prescriptions. Dispensers must report Schedule II-V dispensing within one business day.
