Billing code 95927: Somatosensory testingMedicare rate & RVUs

Medicare pays $170.01 for 95927 nationally in the office. Local office rates run $147.85–$237.46.

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

What 95927 covers

This neurodiagnostic study assesses sensory pathway responses by stimulating peripheral sites associated with the trunk or head and recording the resulting electrical signals from the central nervous system. It may be performed in a neurology or neurophysiology setting by trained technical staff, with a qualified physician interpreting the recordings. The study helps evaluate suspected dysfunction along central sensory pathways; it is distinct from testing focused on upper or lower limb pathways.

Select this code when the documented study covers the trunk or head, rather than the upper or lower limbs. The report should identify the stimulation and recording sites, the responses obtained, and the physician’s interpretation. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier for the global service.

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.
