Blue Cross Blue Shield (BCBS) formularies vary by state and plan type, as BCBS operates through independent regional companies. Most BCBS plans use a 4 to 5-tier formulary system with preferred generics, non-preferred generics, preferred brands, non-preferred brands, and specialty tiers. Your specific BCBS affiliate determines which medications are covered and at what cost.

Sources and standards behind this page

Drug coverage in the United States is governed by published rules rather than by any one insurer's summary, and the sources below are the primary ones. They are linked so a reader can check a claim without taking this page's word for it.

This page describes how coverage and formularies work. It is not medical advice, and a reader's own plan documents and prescriber decide what applies to them.

Frequently Asked Questions

How do I find the BCBS formulary for my specific plan?

Visit your regional BCBS website (e.g., bcbsfl.com for Florida, bcbsil.com for Illinois) and log in to your member portal. Navigate to Pharmacy Benefits or Drug Search. You can also call your plan's pharmacy benefits number on your member ID card.

Does Blue Cross Blue Shield cover weight loss medications?

Coverage varies significantly by plan and state. Some BCBS plans now cover FDA-approved weight loss medications like Wegovy and Zepbound with prior authorization and documented medical necessity (typically BMI 30+ or BMI 27+ with comorbidities). Many employer-sponsored plans still exclude weight loss drugs.

Can I get 90-day supplies through BCBS?

Most BCBS plans offer 90-day supply options through mail-order pharmacies, often at a lower per-day cost than monthly fills. Check with your plan for preferred mail-order pharmacy partners. Some plans also allow 90-day fills at retail pharmacies.
