Summary & Overview
CPT 33287: Phrenic Nerve Stimulator Pulse Generator Removal and Replacement
CPT code 33287 defines the removal and replacement of a phrenic nerve stimulator pulse generator, including vessel catheterization, imaging guidance, and device interrogation and programming when performed. This procedure is clinically important for patients with diaphragmatic pacing systems whose pulse generator has failed, reached end of service, or requires replacement for clinical management. Nationally, the code captures a focused set of device-replacement services tied to implantable neurostimulation therapy.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code represents, typical sites of service, and the clinical context for generator replacement. The publication provides benchmarks for utilization and allowed amounts where available, common billing modifiers and coding considerations, and comparisons across major payers. It also summarizes procedural components bundled into the code and highlights areas where payer policy language commonly appears, such as device longevity, medical necessity criteria, and facility setting requirements.
The content is intended for billing professionals, clinicians involved in device management, and policy analysts seeking a national view of CPT code 33287's clinical definition, coding scope, and payer-relevant considerations.
Billing Code Overview
CPT code 33287 describes the removal and replacement of a phrenic nerve stimulator system pulse generator. The code includes all necessary vessel catheterization, imaging guidance, and interrogation and programming when performed.
Service type: Implantable neurostimulation device revision/replacement
Typical site of service: Hospital outpatient surgical suite or ambulatory surgery center, where device explantation and implantation procedures and intraoperative device programming are normally performed.
Clinical & Coding Specifications
Clinical Context
A 65-year-old patient with chronic central hypoventilation and an implanted phrenic nerve stimulator presents with device battery depletion and intermittent loss of diaphragmatic stimulation. The patient is scheduled for removal and replacement of the pulse generator because the existing generator has reached elective replacement indicator status and device interrogation confirms diminished output. Preoperative evaluation includes device interrogation, chest radiography to confirm lead and generator position, informed consent, and perioperative anesthetic planning (typically monitored anesthesia care or general anesthesia depending on comorbidities). In the operating room, the provider removes the old pulse generator through the original subcutaneous pocket incision, inspects and retains functional leads if intact, implants the replacement generator, performs intraoperative imaging or fluoroscopy as needed to confirm lead position, and conducts device interrogation and programming to verify appropriate phrenic nerve stimulation. Postoperative workflow includes wound closure, immediate device re-interrogation, recovery room monitoring for respiratory stability, instructions for activity restriction, and scheduling of follow-up device clinic interrogation and chest imaging as indicated.
