Summary & Overview
HCPCS G8916: Preoperative IV Antibiotic SSI Prophylaxis Initiated on Time
HCPCS Level II code G8916 denotes a preoperative order for intravenous antibiotic surgical site infection (SSI) prophylaxis with the antibiotic administered on time. This process measure is used in perioperative care to document timely initiation of IV antibiotics prior to incision, a key practice associated with reduced postoperative infection risk. Nationally, proper capture of this code supports quality reporting and can influence hospital and surgical facility performance metrics.
Key payers commonly included in analyses of perioperative quality and reimbursement policies are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise coverage of what the code represents, the clinical context for use in surgical care, and what to expect when the code is used for quality documentation and reporting. The publication summarizes benchmark concepts and relevant policy considerations that affect coding and reporting for perioperative prophylaxis, and provides clinical context for when G8916 is appropriate to report.
This summary is written for a national audience and focuses on code definition, clinical setting, payer relevance, and the types of benchmarks and policy updates readers should look for. Data not available in the input.
Billing Code Overview
HCPCS Level II code G8916 documents a patient with a preoperative order for intravenous antibiotic surgical site infection (SSI) prophylaxis where the antibiotic was initiated on time. This measure captures timely perioperative administration of IV antibiotics intended to reduce the risk of surgical site infections.

-
Typical site of service: Hospital inpatient or ambulatory surgical setting where preoperative IV antibiotics are given prior to surgical incision
Clinical & Coding Specifications
Clinical Context
A 58-year-old male is scheduled for an elective total knee arthroplasty. The preoperative orders include administration of intravenous (IV) antibiotic surgical site infection (SSI) prophylaxis. The operating room (OR) nurse verifies allergy history and timing requirements, and the anesthesia team administers the IV antibiotic within 60 minutes prior to skin incision (or within 120 minutes for agents such as vancomycin or fluoroquinolones). Documentation in the electronic medical record records the agent, dose, route, time of administration, administering clinician, and confirms that the antibiotic was initiated on time per institutional protocol. The patient is taken to the OR, the procedure proceeds, and perioperative nursing and anesthesia teams monitor for adverse reactions. If additional intraoperative dosing is required for prolonged procedures or major blood loss, the intraoperative team documents redosing per weight-based and time-based guidelines.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | Use when substantial additional work beyond the typical service is documented (rare for prophylactic antibiotic administration). |
23 | Unusual Anesthesia |
