Psychiatric Evaluation Bill Explained

What this document usually means

A psychiatric evaluation bill covers the initial assessment a psychiatrist performs to diagnose a mental health condition and recommend treatment. The most common code is 90792, which is a psychiatric diagnostic evaluation that may include prescribing medication. You might also see 90791 if no medication management was involved.

Follow-up visits for medication management are billed separately, often under codes like 99213 or 99214 combined with an add-on code 90833 for psychotherapy if the psychiatrist also provided talk therapy during the visit.

The first things to check

Confirm the date of service and provider name match your appointment. Check whether the evaluation was billed as an initial visit (90792) or a follow-up, since initial evaluations are typically more expensive and take longer. Verify the provider's credentials are listed correctly, as psychiatrists (MD or DO) bill differently than psychologists or therapists.

Look at what your insurance paid versus what you owe. If the full charge was applied to your deductible, you will see a larger out-of-pocket amount than expected.

Common reasons this letter feels confusing

Psychiatric bills often combine evaluation and management codes, which can look like you are being charged twice for one visit. In reality, a psychiatrist may bill for both the medical evaluation component and the psychotherapy component if both services were provided in the same appointment.

Another confusing element is the difference between facility-based and office-based billing. If you saw a psychiatrist at a hospital outpatient clinic, you may receive two bills: one from the psychiatrist and one from the facility.

What to do before you pay or respond

Request an itemized bill if you only received a summary statement. Compare each line to your EOB to confirm the amounts match. If the psychiatrist is in-network, the allowed amount should be lower than the billed charge, and the difference should be adjusted off.

If the bill seems too high, ask the billing office to verify the CPT codes used. Mistakes happen, and a follow-up visit sometimes gets coded as an initial evaluation by error. You can also check your plan benefits to confirm how psychiatric services are covered, including whether you need a referral.
