Summary & Overview
CPT 95873: Nerve Localization Using Electrical Stimulation
CPT code 95873 denotes the use of electrical stimulation to localize specific nerves prior to therapeutic or diagnostic injections. This procedure supports precise delivery of medications—such as local anesthetics or neurolytic agents—by identifying the nerve or nerve branch responsible for a patient’s symptoms. Nationally, accurate nerve localization affects clinical outcomes, procedural efficiency, and billing classification for interventional pain management and related services.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and common sites of service, alongside benchmarking metrics where available, payer coverage considerations, and recent policy or coding clarifications affecting use of this code. The content also highlights common modifiers and administrative notes relevant to claims processing.
This summary is intended for clinicians, billing professionals, and policy analysts seeking a clear, national-level briefing on the clinical purpose of CPT code 95873, typical care settings, and the aspects of payer coverage and coding practice that most influence reimbursement and compliance.
Billing Code Overview
CPT code 95873 describes a procedure using electrical stimulation to identify peripheral nerves to guide medication injection for therapeutic or diagnostic purposes. The technique helps localize specific nerves by eliciting motor or sensory responses, enabling targeted delivery of agents such as anesthetics or neurolytic substances.
Service Type: Diagnostic/Targeted Nerve Localization with Therapeutic Injection Planning
Typical Site of Service: Ambulatory surgical center, hospital outpatient department, or physician office procedure area
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45-year-old with chronic, focal neuropathic pain or spasticity who has failed conservative therapy and is a candidate for targeted peripheral nerve injection or nerve block. The patient arrives to an outpatient ambulatory procedure suite (or hospital outpatient department) after pre-procedure evaluation including medical history, medication reconciliation (anticoagulants reviewed), informed consent, and readiness assessment. In the procedure room, the provider uses percutaneous electrical stimulation to localize the target peripheral nerve(s) by delivering low-intensity current through a stimulating needle while monitoring for motor or sensory responses. Once the nerve is precisely identified, the clinician injects local anesthetic, corticosteroid, or neurolytic medication as indicated. Typical monitoring includes standard vital signs and the presence of an assistant or RN; documentation includes stimulator settings, nerve responses observed, medication(s) and volumes injected, laterality, and any immediate complications. Recovery and post-procedure instructions are provided prior to discharge.
