How do I reconcile patient payments with insurance EOBs?

Start by matching each payment to its corresponding EOB or ERA. Insurance companies typically post payments a few days after generating the EOB. Pull up the EOB and compare it line by line against what actually deposited into your account.

On every EOB, verify three things. The allowed amount is what the insurance agreed to pay based on your contract with them. The contractual adjustment is the difference between your billed charge and the allowed amount. The patient responsibility includes any copay, deductible, or coinsurance the patient owes.

Verify the contractual adjustment matches your fee schedule agreement. Payers sometimes apply the wrong fee schedule or process claims under the wrong contract terms. If the allowed amount looks lower than expected, pull your contract and check. This is one of the most common places where practices lose money without realizing it.

Patient responsibility needs to transfer correctly to the patient’s account. After the insurance pays, the remaining balance should match what the EOB says the patient owes. If your practice management system doesn’t update this automatically, you need to post it manually. Practices that handle medical billing and coding in-house often miss this step or delay it, creating collection problems later.

Watch for partial payments and claim adjustments. Sometimes an EOB shows a different amount than what actually deposited. The payer might have offset against a previous overpayment, applied a withhold, or made an error. These require follow-up because the EOB alone doesn’t explain why the numbers don’t match.

Denials need immediate attention. If a line item shows zero payment with a denial reason code, note it and work the denial quickly. Many denials have appeal deadlines of 60 to 90 days. Missing these deadlines means lost revenue with no recourse.

Do this reconciliation weekly at minimum. Waiting until month-end makes it harder to spot patterns and leaves less time to appeal underpayments or denials. A quick weekly review catches problems while they’re still fixable.

Many medical practices across Metro Detroit struggle with this process because it requires understanding both the clinical coding and the payer contract terms. Working with a medical billing service in Macomb can take this off your plate entirely. EOB reconciliation becomes part of a complete revenue cycle management approach, freeing up your front office staff to focus on patients rather than payment discrepancies.
