Summary: Explains real-time insurance eligibility verification for clinics: how the 270/271 transaction works, CAQH CORE response-time rules (20 seconds real-time, next-morning batch), real-time vs batch vs manual checks, what a response can and cannot tell you, Medicare checks, a software buying checklist and a calculator for staff time saved.
Real-time insurance eligibility verification sends a patient's details to the payer electronically and returns coverage and benefit information while you wait, usually in seconds, instead of by phone call or portal search. It uses the standard HIPAA 270 request and 271 response, and CAQH CORE operating rules set the response times that CORE-certified entities must meet.
This guide explains how it works, the response-time standards, how real-time differs from batch and manual checks, what a response can and cannot tell you, how to choose software and what to expect for therapy clinics. A calculator at the end estimates the staff time you could save. For the broader process, see our insurance eligibility verification guide.
How real-time eligibility verification works
- You enter or select the patient in your scheduling or billing software, with payer, member ID, name and date of birth.
- The software builds a 270 eligibility request and sends it to the payer, usually through a clearinghouse or a direct connection.
- The payer's system checks the member against its records for the date of service.
- The payer returns a 271 response with coverage status and benefit details.
- Your software displays the result and can store it in the patient record, so staff read it instead of keying it in by hand.
For Medicare, CMS's eligibility system gives providers, suppliers and billing agents eligibility data to prepare an accurate claim, determine beneficiary liability or determine eligibility for specific services, per the HHS and CMS description of the Medicare 270/271 eligibility system.
Real-time eligibility response times: the CAQH CORE rules
CAQH CORE operating rules set response-time standards for the 270/271 transaction. They apply to CORE-certified entities, so ask your vendor and payers whether they are certified.
| Mode | Rule | Source |
|---|---|---|
| Real-time | Responses within 20 seconds or less, with conformance counted when 90% of required responses in a calendar month meet that limit | CORE 156 |
| Batch | 270 files submitted by 9:00 pm Eastern on a business day must be answered with 271 responses by 7:00 am Eastern the next business day | CORE 155 |
Sources: the CAQH CORE 156 rule and the CAQH CORE 155 rule. A 20-second maximum is a ceiling, not a typical time, and your actual speed depends on the payer and your connection.
Real-time vs batch vs manual eligibility checks
| Real-time | Batch | Manual (phone or portal) | |
|---|---|---|---|
| How it works | One patient, one electronic request, answer while you wait | A file of many patients sent together | Staff call the payer or search its portal |
| Speed | Seconds, within the CORE limit for certified entities | Next morning for files sent by the evening cutoff | Minutes per patient, longer with hold times |
| Best for | Scheduling calls, same-day patients and check-in | Checking the next day's or week's schedule in one run | Complex questions the electronic response did not answer |
| Watch out for | Problems found at check-in leave little time to fix | Results are only as current as the batch run | Slow, and results depend on who answers |
Many clinics use both electronic modes: a batch run for the upcoming schedule and real-time checks at scheduling and check-in. See also verification vs prior authorization for how eligibility checks relate to authorization.
What a real-time check returns, and what it may not
| Usually returned | May be missing or incomplete |
|---|---|
| Coverage status and effective dates | Network status. UnitedHealthcare states in its guide that network status is not returned on 270/271 transactions (UnitedHealthcare's 2026 Administrative Guide) |
| Plan name and type | Whether a specific service needs authorization, which can need a payer policy check |
| Copay, coinsurance and deductible information | Service-specific limits, such as therapy visit caps, that some payers return only partially |
| Other coverage on file, where the payer returns it | Exact amounts for the service you plan to bill |
Read every response. When a field you need is missing, check the payer portal or call, and note the source.
Why use real-time eligibility verification? What the data shows
The CAQH 2023 Index provider specialty brief put the average cost of a manual eligibility and benefit verification for specialists at $13.61, against $2.32 electronically. Those are industry averages, not your costs. Adoption is already high on the payer side: the 2025 CAQH Index executive report shows medical plans' adoption of fully electronic eligibility and benefit verification at 96% for 2025.
- Fewer calls and portal searches: Staff read a response instead of waiting on hold.
- Earlier problem-spotting: A failed or inactive result at scheduling leaves time to correct details or contact the patient.
- Better estimates: Copay, coinsurance and deductible data support a cost estimate before the visit (see the front-desk verification process).
- Consistency: The same fields are captured for every patient.

How to choose real-time eligibility verification software
| Criterion | What to ask |
|---|---|
| Payer coverage | Which payers return real-time responses, and what happens for payers that do not? |
| Response detail | Which benefit fields show in the result, and how are missing fields flagged? |
| Workflow fit | Can checks run from scheduling, check-in and the patient record, and can you run batch checks? |
| Error handling | How are failed checks reported, and what does staff see when a member is not found? |
| Record keeping | Is each response saved with a date and time in the patient record? |
| Security | Will the vendor sign a HIPAA business associate agreement, and how is data protected? |
| Pricing | Is pricing per transaction, per user or flat, and what is included? |
| Standards | Is the vendor or clearinghouse CORE-certified for eligibility? |
Why real-time eligibility checks fail
- Details that do not match the payer's record: a misspelled name, wrong date of birth or mistyped member ID.
- The wrong payer or plan selected: the payer that administers the benefit may differ from the brand on the card.
- Coverage that ended or has not started on the date of service.
- Payer system downtime or no electronic connection for that payer.
- A response with gaps: some fields are not returned and need a portal or phone check.

Frequently asked questions
What is real-time insurance eligibility verification?
It is an electronic check that sends a patient's details to the payer and returns coverage and benefit information while you wait, using the standard 270 request and 271 response, instead of a phone call or portal search.
How fast is real-time eligibility verification?
Under the CAQH CORE 156 rule, CORE-certified entities must return real-time responses within 20 seconds, for at least 90% of responses in a calendar month. Many checks return faster, but speed depends on the payer and your connection.
What is the difference between real-time and batch eligibility verification?
Real-time checks one patient at a time and returns an answer while you wait. Batch sends a file of many patients, and under CAQH CORE 155 a file submitted by 9:00 pm Eastern on a business day should be answered by 7:00 am Eastern the next business day.
Is there an API for real-time insurance eligibility verification?
Many clearinghouses and eligibility vendors offer APIs that send the 270 request and return the 271 data to your software. Check what payers, fields and response times each vendor supports before you build on one.
Does a real-time eligibility check guarantee payment?
No. It shows coverage and benefits at the time of the check. A claim can still be denied for other reasons, such as missing authorization, coding or documentation, or a change in coverage.
Does a real-time check show network status?
Not always. UnitedHealthcare states that network status is not returned on 270/271 transactions, so confirm network status through the payer portal or by phone.
How do I check Medicare eligibility in real time?
Medicare's eligibility system gives providers, suppliers and billing agents eligibility data, and you typically reach it through a clearinghouse, billing agent or your Medicare Administrative Contractor's portal.
What does real-time eligibility verification cost?
Pricing varies by vendor, and may be per transaction, per user or included in a software subscription. Compare quotes against the staff time the calculator above estimates. SPRY pricing starts at $79 a month.
