Eligibility Verification: What to Check Before the Patient Visit

An “active” eligibility response is only the starting point for a useful pre-visit review. It may not establish that the scheduled service is covered, that the provider is in network, that authorization is complete, or that the displayed patient responsibility will be the final amount. A reliable workflow records what was checked, what remains uncertain, and who must act before the visit.

Verify the exact payer and plan

Confirm the patient’s name, date of birth, subscriber or member identifier, relationship to the subscriber, payer, plan or product, and the expected date of service. Ask whether coverage or coordination of benefits has changed. A card image can help with identifiers and contact information, but it does not prove that coverage is active on the service date.

Use the payer’s available eligibility channel

Many practices obtain electronic eligibility information through a practice-management system, clearinghouse, or payer portal. CMS’s Medicare HETS service uses the HIPAA 270 eligibility inquiry and 271 response to provide real-time Medicare eligibility information to authorized providers, suppliers, and billing agents. CMS notes that the response supports claim preparation, beneficiary-liability review, and eligibility checks for specific services.

Save the transaction or payer reference, date and time, source, and staff member. If the response is incomplete or unclear, use the payer’s provider channel and document the follow-up.

Check these items before the visit

• Coverage status on the expected date of service
• Plan and product type, including network structure
• Primary, secondary, or other coverage indicators
• Provider and facility network status when available
• Benefit category for the planned service
• Deductible, copayment, coinsurance, and out-of-pocket information returned
• Referral, prior authorization, notification, or medical-policy indicators
• Coverage limitations such as frequency, visit, age, diagnosis, or site-of-service rules
• Payer contact information and reference number for unresolved questions

Do not confuse eligibility with authorization or payment

Eligibility indicates enrollment information available at the time of the inquiry. Benefits describe plan terms returned for a service category. Authorization is a separate payer process. Medical necessity and coding are separate reviews. Final payment can still depend on the claim, medical record, contract, coordination of benefits, and payer policies.

Tell patients when an estimate is based on information supplied by the payer and may change after adjudication. Do not present an eligibility response as a payment guarantee.

Use service-specific questions

A generic office-visit inquiry may not answer questions about imaging, surgery, therapy, behavioral health, laboratory testing, drugs, or durable medical equipment. When the automated response does not provide enough detail, ask a focused question that identifies the planned service, date, provider, and location. Record the payer representative or portal source and reference number.

Resolve coordination-of-benefits issues early

If the response shows another payer or Medicare Secondary Payer information, confirm the patient’s current coverage situation and follow the applicable payer process. Do not simply switch the billing order based on an assumption. A stale coordination record can delay both the primary and secondary claim.

Create exception statuses

Use clear statuses such as verified, needs patient information, payer follow-up, network review, authorization needed, coordination-of-benefits review, or financial counseling. Give each exception an owner and due date. A verified status should include the date, source, service category checked, and reference—not only a check mark.

Recheck when timing or facts change

Define when your practice repeats verification. Common triggers include a new month or benefit year, a rescheduled appointment, a changed service, a new payer card, a coverage warning, or a long interval between scheduling and service. The appropriate timing depends on the payer, service, and practice workflow.

Audit the workflow

Track eligibility-related rejections and denials, cases requiring patient outreach, estimates that differ materially from adjudicated responsibility, and appointments delayed by unresolved coverage. Review patterns by payer and location, then correct the earliest reliable step.

Frequently asked questions

Does active coverage guarantee payment?

No. Eligibility is one part of the review. The service, benefits, network, authorization, coding, and other applicable requirements still need consideration.

What should staff do with an unclear benefit response?

Identify the unanswered question, obtain payer clarification through an approved channel, and record the source and next action. Avoid turning an unclear response into a payment promise.

When should verification be repeated?

Recheck when relevant information changes or when the practice workflow identifies a need before service. Follow the plan and service circumstances rather than a universal interval.
