Copayment Tier Definitions


Medications are assigned to one of four categories known as copayment or coinsurance tiers, based on drug usage, cost and clinical effectiveness. Our prescription drug search can show you which tier applies to a specific medication.

Tier 1 (Generic drugs)

  • FDA-approved versions of brand-name medications
  • Features the lowest copayment

Tier 2 (Preferred brand drugs)

  • Brand-name drugs that meet the needs of most patients
  • Second lowest copayment

Tier 3 (Non-preferred brand drugs)

  • Brand-name drugs without a generic version, but have therapeutic alternatives in Tier 2
  • Not used typically as a first line of treatment
  • Some brand-name drugs with a generic equivalent
  • Higher copayment

Tier 4 (Specialty drugs)

  • Medications classified by BCBSNC as those which require special dosing or administering, are typically prescribed by a specialist and are more expensive than most medications
  • Highest copayment or coinsurance amount

If a member chooses a brand name drug when a generic equivalent is available, the member typically will be responsible for paying the difference between the cost of the generic drug and the brand name drug in addition to the higher tier copayment, unless the member’s physician specifically states that the brand name drug is necessary.
