Eligibility Verification

Eligibility verification is the process of confirming a patient's insurance coverage, benefits, deductibles, copays, and authorization requirements before the date of service. It is the single highest-leverage prevention investment in the entire revenue cycle: roughly 25% of all claim denials trace to eligibility issues (CARC CO-4 not covered under plan, PR-1 deductible, PR-2 coinsurance, PR-31 patient cannot be identified). All of those denials are preventable with real-time eligibility verification 48-72 hours before service. Modern eligibility tools query the payer's HIPAA 270/271 transaction directly through clearinghouses like Availity or Trizetto, returning real-time data on plan type, network status, deductible remaining, copay amount, coinsurance percentage, out-of-pocket maximum, prior authorization requirements, and effective dates. The 48-72 hour window matters because plan changes — new employer coverage, plan termination, COBRA transitions, Medicaid eligibility shifts — happen constantly and a stale eligibility check from intake six months ago is unreliable. Practices that automate eligibility verification at the appointment-confirmation step typically reduce eligibility-related denials by 70-85% and recover 2-5 percentage points of net collection rate. Patient-side benefits include catching coverage gaps before service so the patient can resolve them or be informed of self-pay responsibility — preventing collection problems on the back end.
