4049F CPT Reimbursement & Policy Benchmarks

CPT code 4049F denotes a provider-documented order to discontinue prophylactic antibiotics within 24 hours after the end of a noncardiac surgical procedure. The code functions as a perioperative quality measure that supports antibiotic stewardship and aligns with efforts to reduce postoperative antimicrobial overuse and surgical-site infections. Nationally, such measures influence provider reporting, quality initiatives, and may factor into hospital performance programs and payer review.

This analysis covers major payers, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code's clinical and procedural context, benchmarks and reporting considerations where available, and policy-relevant implications for perioperative antibiotic management. The content outlines typical sites of service and the service type associated with the code, and identifies where input data is not available. The material is intended for clinicians, coding professionals, and policy analysts seeking a clear summary of CPT code 4049F and its role in perioperative quality measurement and documentation.

Billing Code Overview

CPT code 4049F documents that the provider ordered discontinuation of prophylactic antibiotics within 24 hours after the end of a noncardiac surgical procedure. This code represents a performance measure tied to perioperative antibiotic stewardship and postoperative infection prevention.

Service type: Perioperative medication management / antibiotic stewardship
Typical site of service: Inpatient or outpatient surgical settings where noncardiac procedures are performed, including hospital operating rooms and ambulatory surgery centers

Data not available in the input.

Clinical Context

A typical patient scenario involves an adult undergoing a noncardiac inpatient or outpatient operative procedure (for example, elective laparoscopic cholecystectomy) during which the surgical team prescribes perioperative prophylactic antibiotics. The surgeon documents an explicit order to discontinue prophylactic antibiotics within 24 hours after the end of surgery, consistent with surgical site infection prevention guidelines. Clinical workflow: preoperative assessment documents indication for prophylaxis and antibiotic choice; intraoperative administration recorded in anesthesia/surgical record; postoperative orders include a stop-time order for prophylactic antibiotics at or before 24 hours after surgery end time; nursing verifies discontinuation at the specified time; discharge summary notes that prophylaxis was discontinued within 24 hours.
