CPT Code Overview

CPT 95910 describes nerve conduction studies consisting of seven or eight studies. These tests evaluate the function of peripheral nerves by measuring electrical conduction velocities and response amplitudes to help characterize neuropathic disorders. The service is categorized under Neurology / Neuromuscular Procedures and is commonly performed in a diagnostic testing facility (POS 11) or an office (POS 11).

Clinical Context

A patient presents to a neurology diagnostic testing facility or office with complaints of numbness, tingling, weakness, or suspected peripheral nerve injury. The clinician performs nerve conduction studies to evaluate peripheral nerve function and documents seven or eight individual motor and/or sensory studies appropriate to the affected limb(s). The workflow includes pre-procedure history and medication review (including anticoagulant use codes if applicable), technical setup and electrode placement by a technologist (technical component), real-time data acquisition, and interpretation by a physician or qualified provider (professional component). Findings are reviewed with the patient and incorporated into the diagnostic plan for conditions such as neuropathy, suspected entrapment neuropathy, or follow-up of prior nerve injury.

Coding Specifications

• Modifier 26: Professional Component — appended when the physician or qualified provider reports only the interpretation and report for the nerve conduction studies separate from the facility or technical service.

• Modifier TC: Technical Component — appended when the facility or testing center reports only the technical performance of the nerve conduction studies (equipment, technologist time) without the physician interpretation.

• Modifier 59: Distinct Procedural Service — appended when the nerve conduction studies are distinct and separate from other procedures performed on the same day (used to indicate a separate session or anatomic site when required by payer policy).

Provider Taxonomies

• 207RN0400X — Neurology

• 2084P0800X — Physical Medicine & Rehabilitation

Related Diagnoses

• I89.0 — Lymphedema, not elsewhere classified (when dual diagnosis required without NEMG)

  Clinical relevance: Lymphedema may prompt evaluation of peripheral limb symptoms where nerve conduction testing helps exclude neuropathic causes of swelling-related paresthesia or to document concurrent nerve dysfunction when electromyography is not performed.

• Z79.01 — Long term (current) use of anticoagulants

  Clinical relevance: Documentation of long-term anticoagulant use is relevant to procedural risk assessment and planning for nerve conduction studies, particularly when additional invasive testing (e.g., EMG) might be considered.

• Z79.02 — Long term (current) use of other antithrombotics/anticoagulants

  Clinical relevance: Similar to Z79.01, this code denotes chronic antithrombotic medication use and is relevant for procedural risk assessment and documentation when scheduling neuromuscular diagnostic procedures.

Related CPT Codes

• 95905: Alternative format for single-limb studies with comparative or consecutive homologous nerve testing; may be chosen when the service is limited to one limb with comparative testing.

• 95907: Reports an individual motor OR sensory study; used in itemized reporting when counting individual studies toward a total.

• 95908: Reports an individual motor AND sensory study; used when both motor and sensory components are obtained in a single study.

• 95909: Represents five or six studies and is a lower-volume band compared with 95910 (seven or eight studies); used when fewer studies are clinically indicated.

• 95911: Represents nine or ten studies and is used when additional studies beyond 95910 are required.

• 95912: Represents 11 or 12 studies for higher-volume testing needs.

• 95913: Represents 13 or more studies for comprehensive multi-nerve testing.

• Common usage notes: 95910 (seven or eight studies) is used when the clinical evaluation requires that number of studies; adjacent codes above or below (95909, 95911, 95912, 95913) are used as alternatives if the actual number of studies performed falls into those ranges. 95907 and 95908 are per-study codes that may be used when itemizing individual motor or sensory studies, depending on payer guidance.
