Pharmacy

Our three CareSource Medicare Advantage plans provide prescription drug coverage. This benefit provides coverage for prescriptions obtained from a retail pharmacy, mail-order pharmacy or specialty pharmacy, and those that are administered in the patient’s home, including drugs administered through a home health agency.

CareSource uses evidence-based guidelines to ensure health care services and medications meet the standards of excellent medical practice and are the lowest cost alternative for the member. These requirements ensure appropriate use of these medications.

Formulary or Preferred Drug List (PDL)

CareSource updates the PDL regularly. Visit the Drug Formulary page for more information.

Restrictions & Limits

Some covered drugs may have additional requirements or limits on coverage. These requirements and limits may include:

  • Prior Authorization: CareSource requires you to get prior authorization for certain drugs. This means that you will need to get approval from CareSource before the prescription is filled. If you don’t get approval, CareSource may not cover the drug.
  • Step Therapy: In some cases, CareSource requires you to first try certain drugs to treat a medical condition before we will cover another drug for that condition. For example, if Drug A and Drug B both treat the medical condition, CareSource may not cover Drug B unless you try Drug A first. If Drug A does not work for you, CareSource will then cover Drug B.
  • Quantity Limits: Certain drugs have limits to the amount of the drug the plan will cover. For example, the plan may provide 30 tablets per prescription for Atorvastatin 80mg. This may be in addition to a standard one month or three-month supply.
