Get Pre-Authorization or Medical Necessity

Pre-Authorization

Pre-authorization is a routine process.  We use it to make sure your prescription drug is:

• Safe
• Effective
• Medically necessaryTo be medically necessary means it is appropriate, reasonable, and adequate for your condition.
• Cost effective

You may need pre-authorization for your prescription if it:

• Is specified by the DoD Pharmacy & Therapeutics Committee
• Is a brand-name prescription drug with a generic substitute
• Has age limits
• Is prescribed for an amount more than the normal limit

Check the TRICARE Formulary to see if you need pre-authorization.
