CPT 95911: Nerve Conduction Studies, 9-10 Tests

CPT code 95911 represents a diagnostic nerve conduction study comprising nine to ten nerve conduction tests. These studies measure the electrical conduction of motor and sensory peripheral nerves and are important for diagnosing conditions such as entrapment neuropathies and other neuromuscular disorders. Nationally, nerve conduction studies are a common component of electrodiagnostic evaluations and influence diagnostic pathways, specialist utilization, and episodic care for patients with suspected peripheral neuropathies.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for CPT code 95911, comparisons with closely related codes such as 95910 and 95912, and operational considerations relevant to billing and coding workflows. The publication also summarizes common modifiers and provider specialties associated with the service, typical sites of service, and common ICD-10 diagnoses linked to nerve conduction testing.

This summary is intended for a national audience of clinicians, coding professionals, and payor policy analysts seeking a clear reference on the purpose and billing context of CPT code 95911. The content focuses on clinical definition, coding relationships, and practical metadata without state-specific policy details.

Billing Code Overview

CPT code 95911 describes a diagnostic nerve conduction study in which the provider performs nine or ten nerve conduction studies to evaluate the electrical conduction function of motor and sensory nerves. This procedure is used to assess peripheral nerve function and to help diagnose neuromuscular disorders.

Service type: Diagnostic nerve conduction study
Typical site of service: Outpatient clinic or hospital-based electrodiagnostic laboratory where nerve conduction studies are performed on limbs and peripheral nerves

National Reimbursement Benchmarks

Commercial averages sit well above Medicare: Blue Cross Blue Shield, Cigna, Aetna, UnitedHealth Group and BUCA all have mean commercial rates notably higher than Medicare’s mean of $152.20; BUCA’s mean of $256.00 in particular is roughly $103.80 above Medicare, highlighting a wide gulf between Medicare payment levels and commercial average contracting for CPT 95911. Dispersion across payers varies: range (P75–P25) calculations show Blue Cross Blue Shield at $97.70, UnitedHealth Group at $162.30, Cigna at $163.60, Aetna at $132.00, and BUCA at $121.90. Cigna and UnitedHealth Group display the widest interquartile spreads (~$163), indicating greater variability in commercial reimbursed rates, while Blue Cross Blue Shield is the tightest at $97.70, suggesting comparatively concentrated commercial pricing.

Clinical & Coding Specifications

Clinical Context

A 48-year-old office worker presents with progressive numbness, tingling, and intermittent nocturnal hand pain in both hands, worse on the right. Physical exam demonstrates positive Tinel and Phalen signs over the carpal tunnels and thenar muscle weakness on the right. The neurologist schedules nerve conduction studies to evaluate median and ulnar nerve function and to quantify severity of focal demyelination/axonal loss. The typical clinical workflow: patient check-in and consent; focused history and focused physical exam; preparation of skin and placement of surface recording and stimulating electrodes; performance of 9–10 nerve conduction studies (motor and sensory studies of median, ulnar, and possibly radial nerves, with comparative or segmental techniques as indicated); optional limited needle electromyography if clinically warranted (separately reported); immediate review of tracings by the performing clinician; documentation of study findings, technical parameters, interpretation, and impression (for example, right greater-than-left median neuropathy at the wrist consistent with carpal tunnel syndrome). Results are provided to the referring clinician and incorporated into treatment planning such as splinting, corticosteroid injection, or referral for surgical consultation.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the physician's interpretation component if a separate technical component is billed by the facility or technologist.
`TC`	Technical component	Use when reporting only the technical portion (equipment, technician) if the physician bills separately for interpretation with modifier `26`.
`25`	Significant, separately identifiable E/M service	Use when a significant evaluation and management service is performed on the same day as the nerve conduction studies and must be reported separately.
`59`	Distinct procedural service	Use when another distinct procedure is performed the same day and appropriate to indicate separate service unrelated to routine bundled documentation.
`52`	Reduced services	Use when the procedure was partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the procedure was started but discontinued due to extenuating circumstances or patient intolerance.
`50`	Bilateral procedure	Use when identical bilateral procedures are reported and payer requires a bilateral modifier (note payer-specific guidance applies).
`RT`	Right side	Use to designate the right-sided procedure when laterality reporting is required.
`LT`	Left side	Use to designate the left-sided procedure when laterality reporting is required.
`GZ`	Waiver of liability statement on file (GA not met)	Use when an advance beneficiary notice is not on file but the service is expected not to be paid; payer-specific.
`KX`	Requirements specified in the medical policy have been met	Use when medical necessity criteria or policy preconditions are satisfied per payer requirements.
`QK`	Medical direction of two, three, or four technicians by a physician/other qualified health care professional	Use when the billing reflects physician supervision/medical direction of multiple technicians during testing.
`QX`	Services performed under an onsite medical direction of a physician by a certified registered nurse anesthetist (not typical for this service but included for completeness)	Use only if applicable and payer recognizes the modifier.
`XP`	Separate practitioner	Use when distinct practitioner performed a portion of the service separate from the primary reporting practitioner.

Taxonomy Code	Specialty	Notes
`2084N0400X`	Neurology	Neurologists commonly perform and interpret nerve conduction studies and EMG testing.
`208200000X`	Physical Medicine & Rehabilitation	Physiatrists frequently perform and interpret electrodiagnostic studies in musculoskeletal and neuropathic disorders.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
