Member Request for Reimbursement Form (PDF)

A drug formulary is a list of prescription drugs approved by your plan. The Meridian Formulary uses the clinical advice of doctors, pharmacists and other medical experts to come up with this drug list.

A PBM is a business that works with insurance companies to fill member prescriptions.

There may be times when your doctor prescribes a drug for you that is not approved in your plan. Your doctor can fill out a PA request form, giving facts about your medical history and why you need the drug. Note: We must approve the drug before you can fill the prescription.

Meridian may deny a drug request for medical reasons. If your doctor's PA request is not approved, you and your doctor will get a letter explaining why. The letter will also explain the appeal process if you and your doctor disagree with the denial.

For some drugs, there are limits to how much you can take safely. This limit is based on research from the drug maker and the FDA. The QL is the amount of drug that can be filled safely each month. If your doctor feels that you need more of a medication, he/she must fill out a PA request.

Sometimes more than one medication can be used to treat your condition. Step therapy means that one medication must be tried first before another medication can be tried. Your healthcare provider or pharmacist can explain which medication must be tried first.
