CPT 95912: Nerve Conduction Studies, 11–12 Tests

Medicare pays $176 on average nationally for this procedure.

CPT code 95912 describes a diagnostic electrodiagnostic procedure consisting of eleven or twelve nerve conduction studies to evaluate motor and sensory nerve conduction function; the service is an electrodiagnostic nerve conduction study typically performed as an outpatient or ambulatory diagnostic procedure in a hospital outpatient department, clinic, or specialized electrodiagnostic lab.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to a neurology or physiatry clinic with symptoms of peripheral neuropathy, focal limb weakness, numbness, tingling, or suspected compressive neuropathy (for example, carpal tunnel syndrome or ulnar neuropathy). The clinician obtains a focused history and performs a neurologic examination demonstrating sensory deficits, motor weakness, diminished reflexes, or provocative maneuvers. When electrodiagnostic testing is indicated, the patient is scheduled for an outpatient electrodiagnostic study session in a dedicated neurodiagnostic lab or electromyography (EMG) suite.

On the day of service the technologist or physician explains the procedure, confirms consent, and verifies the indication and laterality. Skin temperature is measured and standardized. For 95912, the provider performs eleven to twelve nerve conduction studies (NCS) that typically include a combination of sensory and motor studies across relevant nerves (for example median, ulnar, radial, peroneal, tibial, sural) based on the clinical presentation. Findings are recorded, waveforms reviewed, and measurements such as distal latency, amplitude, and conduction velocity are documented. Results are interpreted by the ordering physician (neurologist, physiatrist, or clinical neurophysiologist), and a report is generated describing abnormal findings, diagnostic impressions (e.g., demyelinating vs axonal neuropathy, focal conduction block), and recommendations for further evaluation or management. Typical sites of service are outpatient neurodiagnostic laboratories, hospital outpatient departments, and ambulatory surgical centers equipped for electrodiagnostic testing.
