Summary & Overview
CPT 95925: Short‑Latency Somatosensory Evoked Potential, Upper Limbs
CPT code 95925 denotes a short‑latency somatosensory evoked potential (SSEP) study of the upper limbs, a neurodiagnostic test that evaluates sensory pathways by stimulating peripheral nerves or skin sites and recording central nervous system responses. This code captures a technically focused electrophysiology procedure used across neurology, neurosurgery, and intraoperative monitoring contexts. Nationally, 95925 matters because SSEP testing contributes to diagnosis and perioperative monitoring for conditions affecting sensory conduction, influencing clinical decision‑making and resource use in outpatient and surgical settings.
Key payers included in this review are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for CPT code 95925, typical sites of service, common billing modifiers, and what to expect from payer coverage patterns. The publication summarizes typical use cases, outlines billing considerations, and highlights benchmarking and policy elements relevant to neurodiagnostic services. Where input data is incomplete, the text notes that specific fields are not available. The goal is to provide a clear, national‑level reference for clinicians, billing staff, and policy analysts who manage or evaluate SSEP services.
Billing Code Overview
CPT code 95925 describes a short‑latency somatosensory evoked potential (SSEP) study of the upper limbs. In this procedure, the provider stimulates peripheral nerves or skin sites in the upper extremities and records evoked potentials from the central nervous system to assess sensory pathway function.
Service type: Neurodiagnostic testing / Electrophysiology study
Typical site of service: Hospital outpatient department, ambulatory surgical center, or dedicated neurodiagnostic laboratory
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient presents to an outpatient neurodiagnostic lab with progressive numbness and paresthesia in both hands and intermittent gait instability. The referring neurologist orders a short-latency somatosensory evoked potential (SSEP) study of the upper limbs to evaluate peripheral nerve conduction and central somatosensory pathway integrity. The procedure is performed in a hospital outpatient neurophysiology suite or an ambulatory electrophysiology center. The patient is positioned supine or seated; surface stimulating electrodes are applied to the median nerves at the wrist (or alternative upper-limb sites if needed) and recording electrodes are placed over scalp and cervical spine locations. Stimuli are delivered, responses are averaged and recorded, and waveforms are analyzed for latency and amplitude abnormalities. The interpreting physician documents technical parameters, electrode montage, stimulation intensities, findings (including prolonged central conduction time or absent/abnormal cortical responses), and clinical interpretation. The technical component may be billed separately by the facility and the professional component by the interpreting neurologist or physiatrist. Typical payors for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
