What 93886 covers
A complete transcranial Doppler study evaluates blood-flow signals in intracranial arteries using ultrasound. A vascular laboratory sonographer commonly performs the acquisition, with a qualified physician interpreting the findings. Clinical uses include monitoring for cerebral vasospasm after subarachnoid hemorrhage and evaluating intracranial blood flow in patients with suspected cerebrovascular disease or sickle cell disease.
Report 93886 when the documented examination covers a complete intracranial study; use 93888 when the performed study is limited. The report should identify the clinical indication, vessels or acoustic windows assessed, and interpretation. The code may be billed globally or split into the professional interpretation with modifier 26 and the technical service with modifier TC. The cardiovascular diagnostic multiple procedure reduction applies to the technical component, so it affects the TC portion when applicable.

How to choose
- 93888Transcranial DopplerLimited intracranial study
- 93888 is for a limited intracranial examination; 93886 represents a complete study. Base the choice on the scope actually performed and documented.
- 93880Carotid duplexComplete bilateral extracranial study
- 93880 evaluates extracranial carotid arteries bilaterally, while 93886 evaluates intracranial arteries with transcranial Doppler.
- 93892Emboli detectionWithout injection
- 93892 is specifically for transcranial Doppler emboli detection without injection; 93886 reports the complete intracranial study rather than that emboli-detection protocol.
93886 billing questions
How do I choose between 93886 and 93888?
Use 93886 for a complete intracranial Doppler examination and 93888 for a limited study. The documented scope of the examination should support the selection.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Which portion is subject to the multiple procedure reduction?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. It affects the TC portion when that component is billed.
Can 93880 be reported on the same date?
It may be reported when a separate extracranial bilateral carotid study is also performed and documented. The intracranial Doppler examination does not describe that extracranial study.
Does 93886 include emboli detection?
93886 describes a complete intracranial Doppler examination. Use 93892 when the service includes a separately performed transcranial Doppler emboli-detection study without injection.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
