CPT code 95908: Nerve conduction, three to four studies2026 Medicare rate & RVUs in California

Medicare pays $125.25–$155.16 for 95908 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

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

What 95908 covers

Nerve conduction studies measure how electrical signals travel along peripheral nerves. Neurologists and physical medicine and rehabilitation physicians commonly use them to evaluate symptoms such as hand numbness from suspected median neuropathy at the wrist, ulnar nerve symptoms, or findings suggesting a generalized peripheral neuropathy. Testing may be performed in an office or hospital outpatient setting, and may be paired with needle electromyography when the clinical question also calls for assessment of muscle electrical activity.

Select this code when the total number of separately reportable nerve conduction studies performed is three or four, applying CPT counting rules rather than choosing by diagnosis or number of limbs alone. Document the nerves and methods tested, results, and interpretation. The global service includes the professional interpretation and the technical work, equipment, and staff. Modifier 26 identifies the professional component; modifier TC identifies the technical component. CMS separately prices both modifiers.

How to choose

95907Nerve conductionOne or two studies

95907 applies when the evaluation includes one or two separately reportable nerve conduction studies; 95908 applies at three or four.

95909Nerve conductionFive to six studies

95909 applies when the total is five or six studies, rather than the three or four represented by 95908.

95905Nerve conduction testAutomated device, 1-2 studies

95905 describes motor and/or sensory nerve testing performed using an automated device. Choose between it and 95908 based on the testing method, not by treating it as another study-count level.

95886Needle EMG add-onComplete study, each extremity

95886 reports needle EMG assessment of muscle electrical activity, not nerve conduction testing. It may accompany 95908, but does not contribute to its study count.

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.
