Summary & Overview
CPT 95907: Nerve Conduction Study, One or Two Nerves
CPT code 95907 denotes a focused electrodiagnostic procedure: one or two nerve conduction studies that measure the speed of electrical conduction through peripheral nerves to localize nerve injury. This test is a core diagnostic tool in evaluating neuropathies, entrapment syndromes, and traumatic nerve injury and is widely used across outpatient neurology, physiatry, and surgical practices. Nationally, nerve conduction studies inform clinical decision-making, procedural planning, and post-injury monitoring, making accurate coding and documentation important for clinical and administrative workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical purpose of 95907, typical sites of service, and the service type. The publication also outlines payer coverage considerations, common modifier usage, and related procedure codes where available. Additionally, readers will gain benchmark context and policy updates relevant to electrodiagnostic testing reimbursement and documentation practices. The content is intended to support coding accuracy, billing clarity, and payer communication for practices that perform nerve conduction studies.
Billing Code Overview
CPT code 95907 describes a diagnostic nerve conduction study in which the provider performs one or two nerve conduction tests to measure the speed of electrical impulse conduction through a peripheral nerve. The procedure is used to identify the site of nerve damage or destruction that impairs nerve function.
Service type: Electrodiagnostic testing / Neurodiagnostic procedure
Typical site of service: Outpatient clinic or hospital outpatient department, neurology or electrodiagnostic lab, and similar diagnostic settings
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents to a neurology outpatient electrodiagnostic laboratory with a several-week history of numbness, tingling, and intermittent weakness in the right hand affecting the thumb and first two fingers. The neurologist performs a focused history and neurologic exam, documents sensory and motor distribution consistent with median nerve dysfunction, and orders electrodiagnostic testing. The provider performs one or two nerve conduction studies (95907) to measure conduction velocity and amplitude across the wrist to identify focal slowing or conduction block consistent with compressive neuropathy (for example, carpal tunnel syndrome). The workflow includes pre-test consent and skin preparation, electrode placement, stimulation and recording, documentation of parameters and measured latencies/velocities, interpretation by the physician, and generation of a written report. Testing commonly occurs in an outpatient neurology clinic, hospital outpatient department, or ambulatory electrodiagnostic lab. The typical patient may require bilateral or additional studies in subsequent visits based on initial findings and clinical correlation with electromyography (EMG) when indicated.
