TMS & ECT Procedure Billing for Psychiatric Practices

Understanding TMS & ECT Procedure Billing for Psychiatric Practices

TMS Billing Codes (90867–90869)

TMS is billed under AMA’s CPT code set using CPT 90867 for the initial treatment session (which includes motor threshold determination), 90868 for subsequent treatment sessions, and 90869 for subsequent sessions that require motor threshold re-determination. Always verify the current code descriptors and payer-specific policies before submission, as procedure codes are subject to periodic revision and specific utilization management rules.

ECT Billing Code (90870)

ECT is billed under code 90870. This represents the treatment itself. It is distinct from any related anesthesia or facility charges, which must be billed separately using their own specific codes. When documenting for these procedures, ensuring your outpatient mental health CPT code documentation is precise is mandatory to avoid billing errors.

Why These Claims Get Extra Scrutiny

Both TMS and ECT draw heavier payer scrutiny than routine psychotherapy claims. These are physician-only procedures with significant cost, rigorous documentation requirements, and typically mandatory prior authorization. Payers want to confirm medical necessity and strict adherence to clinical guidelines before processing these claims. If you are struggling with high denial rates for specialized services, consider reviewing your psychiatry billing services setup to ensure your team is fluent in these specific payer intricacies.

Who Can Bill and Perform These Procedures

TMS and ECT are physician-only procedures. A psychiatrist (MD or DO) must perform or directly supervise the treatment. This credentialing distinction is critical; it is different from routine therapy practice billing services where different licensing levels may apply. Always ensure your credentialing file is current with the payer for the specific facilities where these procedures are rendered.

Does insurance cover TMS or ECT for depression?

Coverage varies by payer and typically requires prior authorization. Never assume coverage; verify benefits directly with the specific payer for every patient before the start of the treatment series.

FAQ

Does insurance cover TMS or ECT for depression?
Coverage varies by payer and requires prior authorization in most cases. Always verify benefits directly with the insurer rather than assuming they apply to every clinical scenario.

Why do TMS and ECT claims get more scrutiny than psychotherapy claims?
They are physician-only procedures that carry higher costs, requiring stricter documentation and mandatory prior-authorization approval before billing.

Can a non-physician perform or bill for TMS or ECT?
No. These are strictly physician-led procedures, and they must be performed or supervised by a licensed psychiatrist.

The Takeaway

TMS and ECT billing succeeds or fails on prior-authorization follow-through and precise place-of-service documentation. Confirm both requirements before scheduling the procedure to protect your practice revenue.

Quick Action Checklist

  • Confirm prior-authorization requirements with the specific payer before scheduling the first session.

  • Confirm place-of-service coding matches the exact location where the procedure is performed.

  • Verify the performing or supervising physician’s current credentialing status with the patient’s insurance network.
