Summary & Overview
CPT 95926: Short-Latency Somatosensory Evoked Potential, Lower Limbs
CPT code 95926 identifies a short-latency somatosensory evoked potential (SSEP) study performed by stimulating lower-limb peripheral nerves or skin sites and recording central nervous system responses. This neurophysiologic diagnostic test is used to evaluate sensory pathway integrity and can inform care for patients with suspected spinal cord, peripheral nerve, or central nervous system disorders. Nationally, SSEP testing contributes to diagnostic workflows in neurology, neurosurgery, and intraoperative monitoring contexts.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications and service settings, common payer coverage considerations, and benchmarking of utilization where available. The publication also highlights coding context, typical sites of service (hospital outpatient departments, ambulatory surgical centers, and neurodiagnostic labs), and practical coding notes relevant to documentation and billing.
The content is intended to help revenue cycle, billing, and clinical teams understand the clinical purpose of CPT code 95926, how it fits into neurodiagnostic service lines, and where to look for payer-specific coverage policies and reimbursement guidance. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 95926 describes a short-latency somatosensory evoked potential (SSEP) study of the lower limbs. In this procedure, the provider stimulates peripheral nerves or skin sites in the lower extremities and records resulting evoked potentials from the central nervous system to assess conduction through sensory pathways.
Service Type: Neurophysiology diagnostic testing (evoked potentials)
Typical Site of Service: Hospital outpatient department, ambulatory surgical center, or specialized neurodiagnostic laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45-year-old individual referred to the neurodiagnostic laboratory for evaluation of suspected lumbar spinal cord or cauda equina dysfunction after progressive lower-extremity sensory changes and gait instability. The ordering neurologist documents focal leg numbness, impaired proprioception, and abnormal lower-limb reflexes. The procedure performed is a short‑latency somatosensory evoked potential study of the lower limbs (95926), with stimulation of the posterior tibial or peroneal nerves and recording of cortical and subcortical responses. The clinical workflow includes preprocedure review of indications and contraindications, informed consent, skin preparation and electrode placement, baseline nerve conduction checks, bilateral peripheral nerve stimulation at standardized intensities, recording of central responses, signal averaging and filtering, and technical/physician interpretation. Results are faxed or entered into the electronic medical record and communicated to the referring provider to aid diagnosis of spinal cord compression, demyelinating disease, peripheral neuropathy affecting somatosensory pathways, or intraoperative monitoring planning for future surgery.
