About 93896: Complete TCD vasoreactivity study
Reports a complete transcranial Doppler vasoreactivity assessment of intracranial arteries, performed with a primary TCD procedure to evaluate cerebrovascular response.
This service adds a complete cerebral vasoreactivity assessment using transcranial Doppler (TCD), which measures changes in blood-flow velocity in intracranial arteries during a vasodilatory challenge. Vascular laboratories and neurology services may perform it when evaluating cerebrovascular reserve, including in patients with suspected impaired autoregulation or intracranial arterial disease. The assessment evaluates the response across a complete intracranial TCD examination, rather than documenting baseline flow alone.
Report 93896 only with its required primary TCD procedure; it is an add-on, not a stand-alone service. For a complete intracranial TCD study, the primary procedure is generally 93886. Documentation should identify the arteries assessed, the challenge and response measurements, and the interpretation supporting a complete vasoreactivity evaluation. CMS payment is included within the primary procedure's global period. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and no component modifier represents the global service.
