Mississippi Medicaid: Support medication adherence with 90-day fills

You can help improve medication adherence by prescribing 90-day medication fills for your behavioral health patients. Prescribing 90-day fills to your patients can help to positively impact the Antidepressant Medication Management (AMM) HEDIS® measure. The AMM measure charts the percentage of members ages 18 and older who were treated with antidepressant medication, had a diagnosis of major depression, and who remained on an antidepressant medication treatment.

Benefits of 90-day prescription fills

In addition to impacting the AMM measure, 90-day prescriptions offer several benefits to your patients, including:

  • Cost savings
  • Increased convenience
  • Opportunity for medication synchronization with other medications 
  • Reduced rates of rehospitalization
  • Ability to be delivered by mail in most cases

Supporting strategies

In addition to prescribing a 90-day supply, consider the following strategies to help ensure your patients continue to take their medications:

  • Schedule a follow-up appointment with your patient before they leave the office to help monitor for side effects
  • Provide education on how medication works and ensure patients understand it may take several months for antidepressant medication to be effective
  • Emphasize the importance of continuing medication for at least 6 months even if they begin to feel better or experience side effects


Call the number on the patient's health plan ID card.
