What Is Eligibility Verification?
Eligibility verification is the process of confirming a patient's insurance coverage is active for the date of service, determining the plan benefits (deductible, copay, coinsurance, covered services), and identifying any prior-auth or referral requirements before the encounter.
- Run eligibility for every visit, not just new patients.
- Calculate point-of-service collection responsibility from the 271 response and collect at check-in.
- Practices that lift POS collection to 70%+ of patient responsibility see Cost-to-Collect drop and patient bad debt fall meaningfully.
Eligibility Verification
Also known as: VOB (Verification of Benefits); Eligibility & Benefits Check; Insurance Verification
Eligibility verification is the process of confirming a patient's insurance coverage is active for the date of service, determining the plan benefits (deductible, copay, coinsurance, covered services), and identifying any prior-auth or referral requirements before the encounter.
Definition
Eligibility verification is the front-end RCM step that prevents the largest single class of denials (eligibility-related). It is performed via the X12 270/271 transaction in real time through clearinghouses, payer portals, or PM-system integrations. A complete eligibility check captures: active coverage status, plan type, group number, member ID, deductible (year-to-date and remaining), copay/coinsurance by service category, primary vs secondary coverage, and PA/referral requirements. Best practice is to verify at scheduling (initial) and re-verify within 1-2 days of the actual visit to catch coverage changes.
Example
A new patient calls to schedule. Front-desk runs a 270/271 against UnitedHealthcare with member ID, DOB, and name. Response confirms: active coverage, $1,500 deductible (with $400 met YTD), $40 specialist copay, no referral required for this specialty, PA required for advanced imaging. Front-desk schedules the visit, collects the $40 copay at check-in, and notifies billing of the deductible status for patient counseling.
Common Misconceptions
A passing 270/271 check at scheduling does not guarantee eligibility on the date of service — coverage can change. Re-verifying at check-in (or 1-2 days before for surgeries) prevents most CARC 27 (terminated coverage) denials. Eligibility checks also vary in depth across payers; some return only basic active/inactive without benefits detail.
Practical Application
Run eligibility for every visit, not just new patients. Calculate point-of-service collection responsibility from the 271 response and collect at check-in. Practices that lift POS collection to 70%+ of patient responsibility see Cost-to-Collect drop and patient bad debt fall meaningfully.

CARC 27
CARC 27 indicates a denial because the patient's coverage with the payer had terminated before the date of service, meaning the patient was not insured by this payer on the day services were rendered.

Prior authorization is the payer's process of pre-approving a planned service, procedure, medication, or admission before it is rendered, based on medical-necessity criteria; without an approved PA where required, claims typically deny under CARC 197.

Front-end RCM covers the patient-access activities before the encounter (scheduling, registration, eligibility, prior auth, financial counseling, point-of-service collections); back-end RCM covers post-encounter activities (claim submission, payment posting, denial management, A/R follow-up, patient collections).
