Billing code 95962: Brain mappingMedicare rate & RVUs

Medicare pays $307.96 for 95962 nationally in the office. Local office rates run $275.52–$397.58.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 95962 covers

This add-on represents continued functional mapping during brain surgery, using stimulation or recording from electrodes on the brain surface or depth electrodes to identify areas involved in functions such as movement or language. It may be performed during procedures such as an awake craniotomy for a brain tumor or epilepsy surgery, with the surgeon or a neurophysiology professional assessing responses to stimulation and documenting the functional findings.

Report 95962 only with the primary mapping service, 95961, for documented additional mapping time; it is not a stand-alone service. CMS treats it as paid within the primary procedure’s global period. The service has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment-and-staff component, and no modifier represents the global service. Documentation should support the mapping performed, the functional findings, and the additional time reported.

95938Sensory evoked potentials

95938 reports somatosensory evoked-potential testing, rather than stimulation-based functional mapping of brain areas.

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.
