CVS Caremark (PBM)

CVS Caremark is the largest pharmacy benefit manager (PBM) in the U.S., managing prescription drug benefits for commercial insurers, Medicare Part D plans, and Medicaid managed care. CVS Caremark makes formulary decisions, manages prior authorizations for pharmacy benefit drugs, and operates specialty pharmacy services through CVS Specialty.

Common Denial Patterns

• •Drug not on CVS Caremark formulary or non-preferred tier
• •Step therapy required — CVS Caremark has aggressive step therapy protocols for specialty drugs
• •Quantity limits or days supply restrictions
• •Specialty drug must be filled through CVS Specialty pharmacy (limited pharmacy network)
• •Prior authorization criteria not met per CVS Caremark clinical policy

Step Therapy Approach

CVS Caremark sets formulary tiers and step therapy requirements that client employers and health plans can customize. Their standard formulary aggressively promotes biosimilars and lower-cost alternatives. Step therapy edits are built into the pharmacy claims system and trigger automatically at the point of sale.

Appeal Process

Appeals are handled through the health plan that contracts with CVS Caremark, not directly through CVS Caremark. The health plan's appeal process governs timelines and procedures. Prescribers can request coverage exceptions and peer-to-peer reviews. For Medicare Part D plans managed by CVS Caremark, CMS appeal rules apply.
