Prior Authorization Workflow and Denial Prevention

Match the authorized service, provider, setting, units, and dates to the final claim and retain the clinical decision trail.

Quick answer

An approval number alone is not enough. The authorization must match the patient, payer, plan, provider, service, setting, quantity, and service dates that appear on the claim.

Rules to know

Confirm eligibility and exact plan before requesting authorization.
Capture the payer's clinical criteria and required records.
Recheck changes in code, provider, site, units, and date before service.
Beginning in 2026, impacted payers must provide specific reasons for denied prior authorization decisions under CMS-0057-F requirements.
