Below are important questions to ask your insurance company’s claims representative when researching the coverage provided by your plan for DAYVIGO

  • Is Prior Authorization(PA) required for DAYVIGO?

  • Are there any insomnia treatments I am required to have tried prior to authorizing coverage of DAYVIGO?

    • You may be required to provide documentation of treatments you have tried and failed, if applicable.

  • What is the patient out of pocket costs for the drug, if it is approved?

Appealing a Denial

If you called your insurance company and were told that DAYVIGO is not covered under your plan, or if you tried to fill a prescription for DAYVIGO and you learned that the drug is not covered. This is called a denial of coverage or denial of claim. You may have the right to appeal this decision. You may request from your insurer a detailed explanation in writing as to why you were denied. Once you receive the explanation, read it carefully. Denials may be categorized as either “Prior Authorization” or “Step therapy required.”

“Prior Authorization Required” Categorization

Prior authorization (PA) is a requirement that your physician obtain approval from your health insurance plan prior to prescribing DAYVIGO to you. Speak to your healthcare provider for additional resources to address any PA requirements.

“Step Therapy” Categorization

Your insurer may ask if you have tried and failed at another sleep therapy before trying DAYVIGO. In this case, it is important to include documentation of any previous treatments in your appeal letter. Speak to your healthcare provider to inquire about documentation needs to address “step therapy” requirements.
