CPT code 95864 represents a diagnostic needle electromyography (EMG) procedure that records electrical activity of skeletal muscles at rest and during voluntary contraction while the provider inserts needles and listens to the recordings on a loudspeaker. This electrodiagnostic study is a standard tool in neuromuscular evaluation and has national relevance for diagnosing neuropathies, myopathies, and motor neuron disorders. Accurate coding and understanding of 95864 affects clinical documentation, coverage determinations, and utilization measurement across payers. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn the clinical context of the service, typical sites of care, and the elements that distinguish this procedure from other electrodiagnostic services. The publication summarizes coding specifics, common payer considerations, and benchmarks where available. It also highlights policy and billing topics that commonly affect needle EMG claims, including documentation requirements and procedural scope. Data not available in the input will be noted where applicable; the focus remains on national clinical and coding clarity for providers, billing staff, and policy analysts.
