Summary & Overview
HCPCS G9724: Anticoagulant Medication Use Documented Over Measurement Year
HCPCS Level II code G9724 identifies patients with documentation of anticoagulant medication use that overlaps the measurement year. This measure captures medication exposure relevant to stroke prevention, atrial fibrillation management, venous thromboembolism care, and other conditions requiring anticoagulation. Nationally, clear documentation of anticoagulant use affects quality measurement, care coordination, and population health reporting.
Key payers assessed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis focuses on adoption patterns across major commercial and public payers, implications for reporting workflows, and how this measure integrates with outpatient medication reconciliation and chronic disease management.
Readers will learn the clinical context of G9724, typical sites of service where it applies, and the role it plays in quality measurement and reporting. The publication outlines common billing and documentation considerations, describes what information is available for payers in this review, and flags areas where input data was not provided. This summary supports administrative staff, clinicians, and compliance teams seeking a concise national overview of the code’s purpose and relevance for quality reporting.

Clinical & Coding Specifications
Clinical Context
A 72-year-old male with atrial fibrillation and a history of ischemic stroke attends a primary care visit and medication reconciliation during the measurement year. The clinician documents ongoing anticoagulant therapy (for example, warfarin, apixaban, rivaroxaban, dabigatran, or edoxaban) that overlaps the measurement year to meet quality reporting. Clinical workflow: medication list reconciliation in ambulatory primary care or cardiology; review of pharmacy fill records and patient report; documentation in the electronic health record of anticoagulant name, dose, start date and evidence of continued use during the report period. Typical site of service: outpatient clinic (primary care, cardiology) or anticoagulation management clinic; documentation may also be confirmed via telephone encounter or telehealth visit that is captured in the chart.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required to document anticoagulant therapy overlapped with unusually increased effort (apply per payer rules). |
23 | Unusual anesthesia | Rarely applicable; only when a procedure requiring anesthesia occurred in conjunction with anticoagulation documentation and anesthesia was medically unusual. |
