Summary & Overview
CPT 33281: Phrenic Nerve Stimulator Lead Repositioning
CPT code 33281 covers the surgical repositioning of one or more leads for a phrenic nerve stimulator system, a procedure relevant to management of conditions requiring diaphragmatic pacing. Nationally, the code matters as implanted neurostimulation systems become more common for treating central sleep apnea and select respiratory insufficiency cases, driving surgical follow-up and device maintenance activity. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise guide to what the code represents, typical settings where the service is performed, and the clinical context for lead repositioning. The publication also provides benchmarking and coverage context where available, notes on common claim modifiers, and related procedural considerations affecting billing and documentation. Where administrative or coding details are not provided in the source data, the text indicates "Data not available in the input." The goal is to give clinicians, billing professionals, and policy analysts a clear, national-level summary of CPT code 33281 and the operational issues tied to phrenic nerve stimulator lead repositioning.
Billing Code Overview
CPT code 33281 describes the repositioning of one or more leads for a phrenic nerve stimulator system. This procedure involves surgically adjusting previously implanted pacing leads that stimulate the phrenic nerve to manage conditions such as diaphragmatic pacing for central sleep apnea or respiratory insufficiency.
-
Service type: Surgical lead repositioning for neurostimulation devices
-
Typical site of service: Hospital operating room or ambulatory surgical center

Clinical & Coding Specifications
Clinical Context
A middle-aged patient with an implanted phrenic nerve stimulator presents with diaphragmatic pacing failure and recurrent hypoventilation episodes at night despite prior device implantation. The patient reports decreased stimulation capture on the left-sided lead with intermittent diaphragmatic twitching and nocturnal desaturation documented on home oximetry. Preoperative evaluation includes device interrogation showing high lead impedance and imaging (chest radiograph or fluoroscopy) suggesting lead migration. The clinical workflow includes preoperative anesthesia assessment, device interrogation by electrophysiology or neuromodulation team, informed consent for lead revision/repositioning, perioperative antibiotic prophylaxis, intraoperative fluoroscopic guidance for lead manipulation, intraoperative lead testing to confirm stimulation thresholds and diaphragmatic capture, wound closure, device reprogramming, and postoperative monitoring with repeat device interrogation and chest radiograph as indicated. Typical site of service is an operating room or procedure suite in an outpatient ambulatory surgery center or inpatient hospital setting depending on patient comorbidity and anesthesia needs. The service provided corresponds to repositioning one or more leads of a phrenic nerve stimulator system when lead migration, high impedance, or loss of capture necessitates surgical correction.
