Summary & Overview

HCPCS G8571: Deep Sternal Wound Infection/Mediastinitis within 30 Days Postoperative

HCPCS Level II code G8571 denotes the development of deep sternal wound infection or mediastinitis within 30 days after surgery. This postoperative complication code is used to identify serious infectious events following thoracic or cardiac procedures and is important for clinical quality measurement, postoperative surveillance, and administrative reporting across hospitals and surgical centers.

Key payers included in national analyses are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code's clinical context, common billing considerations, and the typical sites of service where the condition is identified. The publication summarizes benchmarks and reporting implications relevant to quality programs and payer policies, notes where data are available or absent, and situates G8571 within postoperative complication monitoring frameworks.

This summary provides clinicians, billing professionals, and policy stakeholders with a concise reference to the code's purpose and operational context, including what to expect in payer coverage discussions and quality reporting. Data not available in the input are explicitly omitted and indicated where applicable in detailed sections.

Billing Code Overview

HCPCS Level II code G8571 documents the development of deep sternal wound infection/mediastinitis within 30 days postoperatively. This code represents a postoperative complication related to the chest/mediastinal surgical site and is used to capture the occurrence of a significant infectious complication following thoracic or cardiac surgery.

Service Type: Postoperative complication surveillance and reporting
Typical Site of Service: Inpatient hospital (postoperative/critical care units) or outpatient surgical follow-up where postoperative wound infections are identified

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with a history of ischemic cardiomyopathy undergoes elective median sternotomy for coronary artery bypass grafting (CABG). On postoperative day 18 he develops fever, chest pain, erythema and purulent drainage at the sternal incision. CT chest demonstrates fluid collection and mediastinal air consistent with deep sternal wound infection/mediastinitis. Cardiothoracic surgery evaluates the patient, obtains wound cultures, starts broad-spectrum intravenous antibiotics guided by infectious disease, and schedules operative debridement with sternal wound washout, possible partial or complete sternal re‑exploration, and flap coverage if needed. Typical workflow includes documentation of onset within 30 days of the original sternotomy, targeted ICD-10 diagnosis coding, operative CPT coding for debridement and flap or wound closure when performed, and reporting of the HCPCS Level II code G8571 to indicate development of deep sternal wound infection/mediastinitis within 30 days postoperatively.
