How to appeal a TMS (Transcranial Magnetic Stimulation) denial
TMS denials are almost entirely prior auth and medication-trial history, payers require documented failure of multiple antidepressants before they'll approve a full course, and deny sessions beyond the authorized count.
Common code: CPT 90867 (initial/mapping), 90868 (subsequent delivery), 90869 (re-mapping)Why it gets denied
- The payer's policy requires documented failure of a set number of antidepressant trials (often 4+) and adequate psychotherapy
- Prior authorization was missing or covered fewer sessions than delivered
- Sessions were billed beyond the authorized course
- The diagnosis or severity documentation doesn't meet the TMS medical policy
What overturns it
- Document the full medication-trial history with drugs, doses, durations, and outcomes that meet the policy threshold
- Obtain prior auth for the complete course and reconcile session counts to the authorization
- Submit the depression severity scores (PHQ-9) and treatment-resistance documentation
- Pursue a peer-to-peer with the psychiatrist when the trial history is close to the threshold
Worth appealing? A full TMS course runs 30-plus sessions and thousands of dollars, so an authorization gap or a few denied sessions is significant money. It's recoverable because the medication-trial history is already in the chart.
