Generic substitution law Verified 2026-05-23

New York mandates generic substitution. Under New York Education Law § 6816-a, a pharmacist shall substitute a less expensive FDA-approved generic equivalent unless the prescriber has written "d a w" (dispense as written) or "brand necessary" in the prescriber's own handwriting on the face of the prescription. The substituted drug must be on the New York State Drug Formulary maintained by the Department of Health.

Medicaid formulary access Verified 2026-05-23

The New York Medicaid Preferred Drug Program maintains the state PDL and clinical criteria. The state transitioned the pharmacy benefit from managed-care back to fee-for-service under NYRx on April 1, 2023, centralizing pharmacy claims for most Medicaid members. Non-preferred drugs and drugs subject to clinical criteria require prior authorization from the prescriber.

State Pharmaceutical Assistance Verified 2026-05-23

New York operates EPIC (Elderly Pharmaceutical Insurance Coverage), one of the largest and most generous SPAPs in the country. EPIC wraps around Medicare Part D for NY seniors 65+, paying Part D premiums for the lowest-income tier (Fee Plan), reducing copays, and covering many drugs in the Part D coverage gap. EPIC is Medicare-recognized, meaning enrollment counts as creditable coverage and EPIC payments count toward True Out-of-Pocket (TrOOP) costs.

Eligibility: Age 65+, NY resident, enrolled in or eligible for Medicare Part D. Income up to $75,000/year (single) or $100,000/year (married).

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

New York permits 90-day fills of non-controlled chronic medications at retail and mail-order pharmacies. Mail-order pharmacies serving NY patients must be registered as Nonresident Establishments with the NY State Education Department. The state's I-STOP law (Internet System for Tracking Over-Prescribing) requires e-prescribing for all prescriptions including controlled substances since 2016, with limited exceptions for technical failure.

Prescription Monitoring Program Verified 2026-05-23

New York's PMP, branded as the Prescription Monitoring Program Registry under the I-STOP law, requires prescribers to consult the registry before prescribing any Schedule II, III, or IV controlled substance. Pharmacists must report dispensing within 24 hours. Dispensers may also consult the registry voluntarily on any patient.

FAQs about prescription drug law in New York

Will my New York pharmacist substitute a generic without my consent?
