Formularies and Pharmacies for 2019 Plans

Convenient 90-day Prescription Fills

Going to the pharmacy every month to refill your prescriptions can be a hassle. For prescription drugs that you take on an everyday basis, you could be getting a 90 day supply – saving you time and money. Ask your provider if any of the medications you are taking are eligible for a 90-day fill.

Your provider will need to write you a prescription for a 90 day fill. Certain medications, like antidepressants, require an initial 30-day fill.  All Community Health Center pharmacies and some select ESI pharmacy can fulfill a 90 day request. You may also be eligible for free home delivery of your long-term medications. Ask your pharmacy for more information.

New Limits for Opioid Prescriptions from CMS

As of January 1, 2019, there are new 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).

More oversight

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.
