What 95864 covers

A clinician inserts a fine needle electrode into selected muscles in all four limbs and records electrical activity at rest and during muscle contraction. The findings help evaluate conditions such as radiculopathy, peripheral neuropathy, motor neuron disease, or myopathy. Neurologists and physical medicine and rehabilitation physicians commonly perform or interpret the study in outpatient electrodiagnostic laboratories and hospital settings; relevant paraspinal muscles may also be sampled when clinically indicated.

Choose this code when the needle examination covers all four extremities, rather than fewer limbs or a limited muscle sample. The report should identify the limbs and muscles examined, relevant findings, and the clinical question addressed. CMS recognizes a professional interpretation component and a technical component for equipment and staff: report modifier 26 for the professional component, modifier TC for the technical component, or neither modifier for the global service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.
