## Quick answer TRICARE covers controlled substances (such as opioids, stimulants, and benzodiazepines) when they are medically necessary and prescribed by a licensed provider. To prevent misuse, these medications are subject to strict quantity limits, prior authorization requirements, and mandatory state Prescription Drug Monitoring Program (PDMP) checks.
Details
TRICARE follows federal Drug Enforcement Administration (DEA) schedules to categorize controlled substances. Because these drugs have a high potential for abuse and addiction, the Defense Health Agency (DHA) and Express Scripts (the pharmacy benefit manager) apply several layers of oversight.
### Prescription Limits and Fills For most controlled substances, TRICARE enforces the following rules in 2026: * **Supply Limits:** Most Schedule II medications (e.g., OxyContin, Adderall) are limited to a **30-day supply** per fill. * **Refill Restrictions:** Schedule II drugs cannot be refilled; a new prescription is required for every fill. Schedule III-V drugs (e.g., Xanax, Tylenol with Codeine) are typically limited to five refills within a six-month period. * **Opioid Naive Policy:** If you have not taken opioids in the last 90 days, your initial fill for acute pain is generally limited to a **7-day supply**.
### Prior Authorization (PA) Many controlled substances require Prior Authorization. Your doctor must submit documentation to Express Scripts proving that the medication is clinically appropriate. This is common for: * High-dosage opioids (exceeding 90 Morphine Milligram Equivalents per day). * Brand-name stimulants when generics are available. * Medications used for "off-label" purposes.
### Where to Fill * **Military Pharmacies:** Usually have the lowest cost ($0 copay) but may have a more restrictive "formulary" (list of drugs they keep in stock). * **TRICARE Pharmacy Home Delivery:** Managed by Express Scripts. This is the preferred method for long-term maintenance medications, though Schedule II drugs have specific mailing security protocols. * **Retail Network Pharmacies:** Available for short-term needs. In 2026, many retail pharmacies now require electronic prescriptions (e-prescribing) for controlled substances to reduce fraud.
### Fees and Copays (2026 Rates) Copays depend on your beneficiary status (Group A vs. Group B) and the drug's category. For a standard 30-day supply at a retail network pharmacy in 2026: * **Generic:** ~$16 * **Brand-name (Formulary):** ~$43 * **Non-formulary:** ~$92 (unless medically necessary)
## Who this affects * **Active Duty Service Members (ADSMs):** Must typically use military pharmacies; high-dose opioid use may trigger a "Command Interest Profile" to ensure fitness for duty. * **Active Duty Family Members (ADFMs):** Covered under Prime or Select. * **Retirees and their Families:** Subject to standard copays for retail and home delivery. * **National Guard and Reserve:** Those on active duty orders or enrolled in TRICARE Reserve Select.
