CPT 95912 Nerve Conduction Studies Reimbursement | OpenPayer

Summary & Overview

CPT 95912: Nerve Conduction Studies, 11–12 Tests

CPT code 95912 represents electrodiagnostic nerve conduction studies consisting of eleven or twelve individual studies used to assess motor and sensory nerve conduction. Nationally, this code is important for documenting the scope of testing when clinicians evaluate peripheral neuropathies, radiculopathies, entrapment syndromes, and other neuromuscular conditions where objective nerve function data guide diagnosis and management. Payers commonly include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn what services 95912 covers, where the service is typically provided, and the clinical contexts that prompt its use. The publication summarizes common billing considerations, typical sites of service, and related clinical indications. It also outlines benchmarking and payer coverage patterns used by providers and billing staff for national comparisons. Data not available in the input includes specific fee benchmarks, detailed payer policies, and linked ICD-10 diagnoses. The material is presented to inform coding, documentation, and administrative workflows related to nerve conduction testing at a national level.

Billing Code Overview

CPT code 95912 describes a diagnostic procedure involving eleven or twelve nerve conduction studies. This test evaluates the electrical conduction function of motor and sensory nerves, providing objective data on peripheral nerve function.

Service type: Electrodiagnostic nerve conduction studies
Typical site of service: Outpatient electrodiagnostic laboratory or clinic setting where nerve conduction testing is performed

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.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`G56.0`	Carpal tunnel syndrome	Median nerve motor and sensory NCS are commonly performed to confirm and grade entrapment.
`G56.2`	Lesion of ulnar nerve	Ulnar nerve conduction studies assess focal neuropathy at the elbow or wrist.
`G62.9`	Polyneuropathy, unspecified	NCS help characterize length-dependent sensory-motor polyneuropathy and differentiate axonal vs demyelinating patterns.
`G59.0`	Compression of radial nerve	Radial motor and sensory studies evaluate focal compressive mononeuropathies.
`M54.10`	Radiculopathy, lumbar region, unspecified	NCS with EMG distinguish radiculopathy from peripheral nerve lesion when limb symptoms overlap.
`M54.16`	Radiculopathy, lumbosacral region	Used when lower extremity nerve conduction and EMG evaluate suspected nerve root involvement.
`G61.0`	Guillain-Barré syndrome	Serial NCS document demyelinating conduction slowing and are critical in diagnosis and staging.

CPT Code	Description	Relationship to This Procedure
`95860`	Needle electromyography (EMG), 1 extremity with or without related paraspinal areas; limited study	Often performed in the same session when muscle denervation or myopathy is suspected in addition to NCS.
`95861`	Needle EMG, 2 extremities with or without related paraspinal areas; limited study	Performed when symptoms involve multiple limbs; complements `95912` by assessing individual muscle electrical activity.
`95905`	Nerve conduction, amplitude and latency/velocity study, each nerve; motor	Used for single motor nerve studies when fewer studies than `95912` are performed; may be part of the total laboratory testing.
`95907`	Nerve conduction studies, motor and sensory, 5-6 studies	Represents a smaller set of NCS; used when fewer nerves are evaluated than for `95912`.

`25`	Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure	Use when a distinct E/M visit is performed the same day as `95912` and must be reported separately.
`26`	Professional component	Use if reporting only the physician interpretation/overread of the NCS when the technical component is billed separately.
`TC`	Technical component	Use when billing only the technical component (equipment, technologist) for nerve conduction studies.
