When you enroll in our Partners Charter Plus Rx^TM Plan, Partners Apex Plus Rx^TM Plan, Partners Sound Plus Rx^TM Plan or Partners Summit Plus Rx^TM Plan, you have the advantage of Part D prescription drug coverage.

Covered drugs for these plans are listed in our formulary, which is developed in consultation with a team of health care providers. The comprehensive formulary represents the prescription therapies believed to be a necessary part of a quality treatment program.

Partners Charter Plus Rx^TM Plan, Partners Apex Plus Rx^TM Plan, Partners Sound Plus Rx^TM Plan, or Partners Summit Plus Rx^TM Plan will generally cover the drugs listed in our formulary as long as the drug is medically necessary, the prescription is filled at one of our network retail or mail-order pharmacies and other plan rules are followed.
