Summary & Overview
HCPCS G8970: No or One Moderate Risk Factor for Thromboembolism
HCPCS Level II code G8970 represents a clinical assessment indicating no risk factors or a single moderate risk factor for thromboembolism. Nationally, standardized use of this code supports consistent documentation of venous thromboembolism (VTE) risk status, which affects prophylaxis decisions, quality measurement, and care coordination across outpatient and ambulatory settings. Consistent coding facilitates performance measurement and clearer communication among clinicians, payers, and health systems.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context and service setting, common modifiers associated with billing, and the typical use cases for documenting low to moderate VTE risk. The publication also outlines what to expect in payer coverage approaches and common administrative considerations for claim submission.
This summary provides benchmarks for expected utilization, discusses relevant policy updates that affect risk-assessment reporting, and situates G8970 within clinical workflows for ambulatory risk stratification. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code G8970 denotes no risk factors or one moderate risk factor for thromboembolism. This code is used to document assessment of thromboembolic risk when the clinical evaluation identifies either an absence of risk factors or a single moderate risk factor.

Clinical & Coding Specifications
Clinical Context
A 58-year-old ambulatory patient is admitted for an elective total hip arthroplasty under a same-day outpatient surgical pathway. Preoperative risk stratification for venous thromboembolism (VTE) is performed in the preoperative clinic. The patient has either no VTE risk factors or only one moderate risk factor (for example, age 58 with well-controlled hypertension but no prior VTE, active cancer, or thrombophilia). The clinical workflow includes: preoperative assessment by the surgeon or preoperative nurse practitioner, documentation of VTE risk level in the medical record, selection of a standard perioperative VTE prophylaxis regimen consistent with institutional protocol (mechanical prophylaxis and/or a standard pharmacologic agent), intraoperative care by the surgical team, and postoperative orders for routine prophylaxis and monitoring. Billing for the VTE risk stratification level corresponding to code G8970 is recorded in the outpatient or ambulatory surgery claim when the documented assessment supports "No risk factors or one moderate risk factor for thromboembolism." Typical sites of service include outpatient surgical centers, hospital outpatient departments, and preoperative clinics associated with ambulatory surgery units.
