This article provides billing/coding guidelines that complement Local Coverage Determination L34417 for CT of the head; consult LCD L34417 for specific coverage, coding, and documentation requirements.
Refer to LCD L34975 for the detailed reasonable and necessary clinical criteria and documentation required to support coverage of NEPs.
Use CPT codes 95925, 95926, 95927, 95928, 95929, 95938, and 95939 for Somatosensory Evoked Potentials/Responses (SEPs/SERs).
Use CPT codes 92651, 92652, and 92653 for Brainstem Auditory Evoked Potentials/Responses (BAEPs/BAERs).

Neurophysiology Evoked Potentials (NEPs) — including Somatosensory Evoked Potentials (SEPs), Brainstem Auditory Evoked Potentials (BAEPs/BAERs), and Visual Evoked Potentials (VEPs/VERs) — are covered when determined to be reasonable and necessary in accordance with LCD L34975.
CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
Initial lumbar MRI is covered when the test is medically reasonable and necessary and the medical record documents clinical rationale and supports the ICD-10-CM code(s) billed.
A second lumbar MRI for the same patient is allowable when documentation shows comparative test results are needed to make a more definitive treatment decision.
Multiple scans of different body areas performed on the same day for the same patient are payable when each scan is reasonable and necessary.
