HCPCS G9197: Order for First- or Second-Generation Cephalosporin for Antimicrobial Prophylaxis

HCPCS Level II code G9197 denotes documentation of an order for a first- or second-generation cephalosporin prescribed for antimicrobial prophylaxis. The code captures a specific clinical documentation event tied to infection prevention in procedural care and surgical settings. Nationally, clear documentation of prophylactic antibiotic orders supports patient safety, appropriate perioperative care, and administrative workflows related to quality measurement and claims processing.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent, typical sites of service, and common billing contexts. The publication outlines benchmarking approaches and where this code fits within perioperative documentation and quality reporting. It also highlights common modifiers used with procedural and medication-related service lines when such documentation appears on claims. Where applicable, the summary indicates when input data was not provided.

This national-level summary is intended for coding managers, clinical documentation improvement teams, revenue cycle leaders, and policy analysts who need a focused reference on the purpose and administrative use of G9197. It does not provide patient-specific guidance or clinical recommendations.

Billing Code Overview

HCPCS Level II code G9197 documents the order for a first- or second-generation cephalosporin for antimicrobial prophylaxis. This entry represents documentation that an authorized prescriber has ordered a cephalosporin antibiotic intended for prophylactic use to prevent surgical site or procedure-related infections.

Service Type: Medication order / Antimicrobial prophylaxis documentation

Typical Site of Service: Hospital inpatient or outpatient surgical settings, ambulatory surgery centers, and other procedural care locations

Clinical Context

A 54-year-old male scheduled for elective outpatient inguinal hernia repair (open technique) presents on the day of surgery. Per surgical prophylaxis protocols, the anesthesiologist or surgeon documents and places an order for a first- or second-generation cephalosporin (for example, cefazolin or cefuroxime) to be administered within 60 minutes prior to incision. The workflow includes confirmation of allergy status, selection of appropriate dose by weight and renal function, electronic medication order entry in the perioperative record, and nursing verification of administration time and route (intravenous). Documentation of the order in the medical record (timing, drug, dose, and indication: antimicrobial prophylaxis) supports the HCPCS Level II code G9197 and facilitates quality reporting and billing reconciliation.

`363A00000X`	Anesthesiology	Anesthesia providers often document timing and administration of prophylactic antibiotics in the perioperative record.
`207Q00000X`	Family Medicine	Family medicine physicians may place or verify prophylactic antibiotic orders in ambulatory surgical settings.
`207K00000X`	Emergency Medicine	ED clinicians may document prophylaxis when procedures or urgent operations are arranged.
`363L00000X`	Nurse Anesthetist	CRNAs document and confirm administration timing in the anesthesia record.
