You can check which prescription drugs are covered under your insurance plan by looking at your insurance plan’s list of covered prescription drug coverage, also known as a formulary. This list is usually available on your insurance company’s website, or you can call the customer service number on your insurance card to request a copy. You can also ask your pharmacist or doctor if they have a copy of the formulary or check with your insurance company’s app or member portal. You can also consult your insurance company’s customer service representative, who can provide detailed information about your plan’s coverage.
