Pharmacy benefits · New York · Last reviewed June 2026
Filling a workers' compensation prescription in New York runs on different rules than your normal pharmacy visit. The bill goes to your WC carrier (or their pharmacy benefit manager — Optum, myMatrixx, Mitchell, Healthesystems, or one of a few others), the price is set by the New York fee schedule, and the drug has to clear the NY WC Drug Formulary before the pharmacist will release it to you.
New York runs a closed formulary, which means non-listed drugs require prior authorization from the carrier before dispensing. Closed drug formulary effective December 2019 for new claims, July 2020 for legacy claims. Two-tier: Phase A (acute) and Phase B (perioperative/chronic). Drugs outside the formulary require prior authorization.
Pharmacy fee schedule mirrors the Medicaid Drug Rebate Program pricing for generics; brand at AWP − 12% or the federal upper limit, whichever is lower.
Opioids beyond 7 days for acute pain or beyond 30 days cumulative require justification. New York maintains a separate opioid-specific list with morphine-equivalent caps tied to claim duration.
The Phase A / Phase B split is unusual. Phase A covers the first 30 days post-injury and is generous on acute-pain drugs; Phase B (after 30 days) is more restrictive. Make sure your prescriber documents which phase applies to avoid an automated denial.
Official source: NY WCB Pharmacy Formulary. Confirm coverage before refilling chronic prescriptions — state formularies are revised periodically and a drug covered last year may need prior authorization now.
The pharmacy benefit manager handling your claim depends on which insurance carrier (or third-party administrator) your employer uses. The major WC PBMs operating in New York include:
Your claim paperwork lists the PBM by name. If you can’t find it, ask your claims adjuster directly.
