Summary & Overview
HCPCS G9674: Patients with Clinical ASCVD Diagnosis
HCPCS Level II code G9674 identifies patients with a clinical diagnosis of atherosclerotic cardiovascular disease (ASCVD). Nationally, accurate identification of ASCVD in billing and administrative data supports population health management, quality measurement, and risk stratification for cardiovascular care. This code matters for clinical programs addressing secondary prevention, medication management, and care coordination for high-risk patients.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how the code is used in practice, the clinical context for ASCVD-related services, and what to expect from payer coverage patterns. The publication outlines common service settings and the types of outpatient cardiovascular care associated with the code.
The report provides benchmarks where available, highlights relevant policy updates affecting ASCVD documentation and billing, and summarizes clinical considerations for coding consistency. Data limitations are noted when input fields were not provided. The content is intended for a national audience of billing professionals, clinicians, and policy analysts seeking concise context about HCPCS Level II code G9674 and its role in ASCVD-related service classification.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with documented clinical atherosclerotic cardiovascular disease (ASCVD) presents for routine secondary prevention management in an outpatient cardiology clinic. The patient has a history of prior myocardial infarction and peripheral arterial disease, is on lipid-lowering therapy, and requires documentation and care coordination to confirm the ASCVD diagnosis, optimize guideline-directed medical therapy, and schedule follow-up. The clinical workflow includes: initial intake and problem list review, focused cardiovascular history and medication reconciliation, targeted physical exam, review of prior cardiac procedures and imaging, assessment of risk-factor control (blood pressure, LDL cholesterol, smoking status, diabetes control), reconciliation of current therapies (antiplatelet agents, statins, ACE inhibitors/ARBs, PCSK9 inhibitors if applicable), and documentation of ASCVD for billing with code G9674. Patient education and care plan are documented, and referrals or prior authorization requests are initiated if advanced therapies or procedures are considered.
Coding Specifications
| Modifier | Description | When to Use |
