Summary & Overview
HCPCS S0340: Lifestyle Modification for Coronary Artery Disease, First Quarter
HCPCS Level II code S0340 represents a structured lifestyle modification program for management of coronary artery disease, covering the first quarter or stage of comprehensive supportive services. This code captures non-procedural, programmatic care focused on risk-factor modification, patient education, and behavioral change as part of cardiac rehabilitation pathways. Nationally, such services address a high-burden condition and align with efforts to reduce recurrent cardiac events and prevent progression of disease.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what S0340 denotes clinically and operationally, common billing contexts, and the payer landscape for coverage consideration. The publication summarizes benchmarks and payer policy patterns where available, clarifies the typical sites of service and service type, and outlines practical coding context to support billing teams and policy analysts in identifying where this code fits within broader cardiac rehabilitation and chronic disease management programs.
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes are noted where relevant. The report is intended for national audiences including clinicians, coding professionals, and payer-policy analysts seeking a clear summary of the code's purpose and typical use.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with established coronary artery disease is referred to a multidisciplinary lifestyle modification program following a recent noninvasive cardiac evaluation demonstrating stable ischemic heart disease. The program addresses risk-factor optimization (smoking cessation, dietary counseling, weight management, blood pressure and lipid control, physical activity prescription), medication adherence support, and psychosocial counseling. The enrollment visit (first quarter / stage) is scheduled at an outpatient cardiac rehabilitation or preventive cardiology clinic and is led by a cardiologist or a multidisciplinary team including a registered nurse, registered dietitian, exercise physiologist, and behavioral health specialist. Initial workflow: intake and medical history review, baseline vitals and risk-factor measurements, individualized goal setting, patient education on diet and exercise, creation of a structured activity plan, referrals as needed, and scheduling of follow-up sessions for the quarter/stage. Typical sites of service include outpatient hospital-based cardiac rehabilitation centers, freestanding outpatient clinics, and physician offices that provide structured secondary prevention programs. Payors commonly involved in coverage determinations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
