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.
