Drug Coverage

TRICARE covers most prescription drugs approved by the U.S. Food and Drug Administration. The TRICARE Formulary is a list of generic and brand-name prescription drugs TRICARE covers. Check the formulary for coverage information for specific drugs.

Prescription drugs may be covered under the TRICARE pharmacy benefit or the medical benefit.

Drug Categories

Prescription drugs fall into four categories. These categories follow industry standards. They depend on the medical effectiveness and cost effectiveness of a drug compared to other similar drugs.

  1. Generic formulary drugs
  2. Brand-name formulary drugs
  3. Non-formulary drugs
  4. Non-covered drugs

A drug’s category may affect your pharmacy costs.

Generic formulary drugs: Covered by TRICARE, widely available, and lowest cost to you.Brand-name formulary drugs: covered by TRICARE, generally available, moderate cost.

Non-formulary drugs: Covered by TRICARE, may not be available, higher costNon-covered drugs: Not covered by TRICARE and highest cost. You pay 100% of the drug's cost.

Generic Formulary Drugs

Generic drugs are just as potent, pure, safe, and reliable as brand-name drugs. The U.S. Food and Drug Administration requires that all generic drugs pass strict testing to prove they are the same.

Generic drugs have the lowest out-of-pocket costs to you.

Brand-Name Formulary Drugs

If you’re prescribed a brand-name drug, you’ll get a generic substitute, unless:

  • There isn&rsquot a generic substitute.
  • Express Scripts approves use of the brand-name drug.
  • TRICARE determines the brand-name drug is a better value than its generic equivalent.

Express Scripts may approve a brand-name drug if your doctor:

  • Completes a clinical review that says the brand-name drug should be used instead of the generic drug, and Express Scripts grants the approval.
  • Calls Express Scripts to request the brand-name drug for you. 

Do you take a brand-name maintenance drug? You may be required to fill your prescription through TRICARE Pharmacy Home Delivery.

In general, you’ll pay more out-of-pocket for brand-name drugs than for generic drugs.

Non-Formulary Drugs

Non-formulary drugs are drugs that aren’t as clinically effective or cost-effective as other drugs in the same therapeutic clast. Covered non-formulary drugs have higher cost-shares than drugs in the generic formulary or brand-name formulary categories.

  • Some non-formulary drugs are only covered through TRICARE Pharmacy Home Delivery.
  • If your provider can establish medical necessity, you can get the non-formulary drugs at the formulary cost-share (or at no cost for active duty service members). 

Non-Covered Drugs

Prescription drugs and other products TRICARE doesn’t cover include:

  • Excluded drugs listed in the non-covered category
  • Drugs prescribed for cosmetic purposes
  • Drugs used to treat a non-covered condition (such as prescription drugs for treatment of presbyopia)
  • Fluoride preparations
  • Homeopathic and herbal preparations
  • Multivitamins (prenatal vitamins with a prescription are covered)
  • Over-the-counter products, except for:

You can get prescriptions filled for non-covered drugs, but you’ll have to pay the full cost of the drug. The amount you pay for the excluded drug won’t apply to your catastrophic cap.

Prescription Quantity Limits

Quantity limits vary by type of pharmacy:

Exceptions can be made if your provider establishes medical necessity.
