Summary & Overview
CPT 33223: ICD Pocket Relocation for Infection or Erosion
CPT code 33223 represents the surgical relocation of an implantable cardioverter-defibrillator (ICD) pocket to a new site, typically undertaken in response to complications such as infection or device erosion at the original implantation site. The procedure preserves device therapy while addressing local tissue compromise, and it carries implications for inpatient and procedural billing, infection-control protocols, and device-management workflows nationwide. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of clinical context, payer coverage considerations, common billing modifiers, and where available benchmarks and policy updates apply to pocket relocation procedures. The publication outlines clinical indications prompting relocation, typical sites of service (hospital operating rooms or electrophysiology suites), and billing nuances that affect coding and reimbursement for the service line. Data not available in the input is identified where applicable. This summary equips clinicians, billing professionals, and policy analysts with a clear understanding of what CPT code 33223 captures and the areas to review when assessing coverage, claims submission, and hospital procedural workflows for ICD pocket relocation.
Billing Code Overview
CPT code 33223 describes a surgical procedure to create a new subcutaneous pocket in a different location and relocate an existing implantable cardioverter-defibrillator (ICD) device pocket. This procedure is performed when complications such as infection, device erosion, or other local issues at the original implantation site require removal of the device from that pocket and creation of a new pocket for continued device function.
-
Service type: Surgical device pocket relocation and reimplantation procedure
-
Typical site of service: Hospital operating room or cardiac electrophysiology procedure suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old man with an existing transvenous implantable cardioverter-defibrillator (ICD) implanted in the left subclavian region who presents with pocket infection characterized by swelling, erythema, purulent drainage, and positive wound cultures despite antibiotic therapy. The cardiology-electrophysiology team evaluates the patient, documents device-related infection and pocket erosion, and determines that device removal and relocation are necessary. In the operating room under monitored anesthesia care or general anesthesia, the electrophysiologist explants the generator from the infected pocket, assesses and, if indicated, extracts or manages leads, creates a new subcutaneous or submuscular pocket on the contralateral chest (or alternate site), repositions or reimplants the defibrillator generator into the new pocket, ensures appropriate lead function and device programming, and closes the wounds with appropriate drainage and antibiotic coverage. Typical perioperative workflow includes preoperative imaging and labs, intraoperative device interrogation, sterile explant and relocation, and postoperative device interrogation and wound care. Typical sites of service are an inpatient operating room or ambulatory surgical center depending on infection severity and need for hospitalization.
