Limits for Opioid Prescriptions from CMS
Effective January 1, 2019, there are additional limits on opioid prescriptions for members who have Medicare Part D. This change follows guidance from the Centers for Medicare & Medicaid Services (CMS).
- Members who are filling a first-time prescription for opioids to treat acute pain won’t be able to get more than a seven-day supply at one time.
- Pharmacists will be required to consult with the prescriber for opioid prescriptions greater than 90 morphine equivalent dose (MME) per day.
These limits don’t apply to members who:
- Live in a long-term care facility.
- Are in hospice and receiving end-of-life care.
- Are being treated for active cancer-related pain.
- Are prescribed buprenorphine products for medically assisted treatment (MAT).
CMS recommends more oversight and monitoring of opioid prescription to address current trends and safety concerns. Medication reviews may result in a member being assigned to a single pharmacy and a single subscriber for controlled substances in order to better coordinate care and case management.
