CPT code 95928: Motor evoked potentials, upper limbs2026 Medicare rate & RVUs

Medicare pays $256.18 for 95928 nationally in the office. Local office rates run $225.90–$350.51.

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

What 95928 covers

This study evaluates motor pathway conduction from the brain to upper-limb muscles by stimulating the motor system and recording the resulting responses. It is commonly used during procedures such as cervical spine surgery when the team needs to monitor motor pathway function. A neurophysiology professional interprets the responses, while trained technical staff may perform the acquisition in an operating room or diagnostic setting.

Select 95928 for upper-limb motor evoked potential testing; use the code for the bilateral service rather than adding modifier 50 to increase payment. Documentation should identify the tested limbs, stimulation and recording performed, results, and the interpretation. Medicare recognizes professional and technical components: modifier 26 reports interpretation, modifier TC reports equipment and staff, and no component modifier represents the global service. The components are separately priced.

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.
