Health Plan Contact Information
The Medical Society has assembled this directory to make it easier to get started when you need to reach a health plan. We’ve gathered the provider lines, portals, and leadership for the plans working in Western New York in one place, so a claim, authorization, or coverage question has a clear first step.
Before you call: for a claim-specific question, the number on the patient’s member ID card is often the most direct route, since lines vary by plan and product. The numbers below reach each plan’s line for medical offices, updated July 2026.
