Eligibility checks that actually prevent denials

Most practices run eligibility. Fewer read the response. The check comes back "active", somebody moves on, and six weeks later the claim is denied for a reason the response already contained.

Active coverage answers one question. The denials that hurt come from the other four.

Read past active or inactive

Is this plan the right payer? Patients change plans and keep the old card. The eligibility response names the current payer, and sending to the one on the card produces CO-109, where the payer tells you the claim was never theirs to pay. That denial costs a full billing cycle to discover.

Is the specific service covered? Active coverage is not blanket coverage. Plans carve out behavioral health to a separate benefits manager, exclude specific procedures and cap visit counts. When the service is not in the plan, the result is PR-204, and the balance moves to the patient who was never warned.

Does it need prior authorization, and is the one you have still valid? Authorizations expire, are tied to specific CPT codes and sometimes to a specific rendering provider. An authorization for the right patient and the wrong code does not help.

How many visits are left? Plans with visit limits will pay up to the cap and deny after it, which shows up as CO-151 when the payer decides the frequency is not supported. For physical therapy and behavioral health, where treatment runs over many sessions, this is the difference between a course of care that gets paid and one that stops being paid halfway through.

When to run it

Twice. Once when the appointment is booked, so a coverage problem can be solved before the patient arrives. Once within about 48 hours of the visit, because the first check goes stale. Plans terminate at month end, employers change carriers in January, and a check run three weeks ago tells you what was true three weeks ago.

The second check is the one practices skip, and it is the one that catches terminations.

Write down what you read

An eligibility response you did not record is a check you cannot prove you ran. Capture the payer, the plan, the effective dates, the authorization number and the reference number for the check itself, in the patient record, before the visit.

This matters twice. It is what lets the front desk tell the patient what they will owe before the appointment rather than in a statement afterwards. And when a payer denies a claim for coverage that their own system confirmed, the reference number is the appeal.

The part that is not a systems problem

The information above is available before the patient is seen. What stops it being used is usually that the person running the check has four minutes between patients, not that the data is missing.

That is why eligibility verification sits inside our virtual medical assistant work rather than being treated as a billing task. It happens before the encounter, it belongs to the front desk, and it is the cheapest denial prevention available to a practice.
