What Is Prior Authorization?
Prior authorization (PA) — also called pre-authorization or pre-approval — is a requirement by health insurance companies that your prescriber obtain approval before they will cover a specific medication. For biologics, which can cost $5,000–$9,000/month at list price, prior authorization is required by virtually every insurance plan.
The Prior Authorization Process Step by Step
- Prescription received — Your prescriber sends your biologic prescription to BiologicHealthPlus
- Insurance verification — We contact your insurer to confirm your benefits and PA requirements
- Clinical documentation — We obtain your diagnosis, treatment history, lab results, and prior therapy records from your prescriber
- PA submission — We submit a complete prior authorization request to your insurance company
- Insurer review — Your insurance company reviews (typically 3–10 business days; urgent cases may be 24–72 hours)
- Approval or denial — If approved, we fill and ship your medication. If denied, we file an immediate appeal
- Appeal (if needed) — We submit a peer-to-peer review request and/or formal appeal with additional clinical support
Common Reasons for PA Denial — and How We Fight Them
Step Therapy Required
"You must try Drug A before Drug B." We document your clinical history and argue medical necessity for the prescribed biologic, especially if you have already failed or are contraindicated for step therapy.
Not Medically Necessary
We provide detailed clinical documentation — disease activity scores, lab values, treatment failure records — to demonstrate that the prescribed biologic is medically necessary.
Off-Label or Indication Mismatch
We ensure the prescription diagnosis code aligns with the approved FDA indication and submit supporting literature if needed for legitimate off-label use.
Missing Documentation
We proactively gather all required documentation before submitting, and follow up with your prescriber for any additional records needed during the review.
