HCPCS G9004: Coordinated Care Fee, Risk-Adjusted Low, Initial
HCPCS Level II code G9004 denotes an initial, risk-adjusted coordinated care fee for patients classified as low risk. As a billing code for care coordination, G9004 captures reimbursement for the initial administrative and clinical activities required to establish a coordinated care plan, facilitate communication among clinicians, and begin ongoing management. Nationally, such codes are important as payers increasingly emphasize value-based care and funded care management services.
Key payers considered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how G9004 is used to bill initial coordinated care for low-risk patients, summaries of payer coverage patterns where available, and context on how this code fits within care management and value-based payment frameworks. The publication also outlines common modifiers associated with care coordination billing and highlights what benchmarks and policy updates to watch for that affect utilization and reimbursement for initial coordinated care fees.
This summary is designed for billing managers, practice administrators, and policy analysts seeking a concise national-level briefing on the role and application of HCPCS Level II code G9004 in ambulatory care coordination.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with multiple chronic conditions (for example, congestive heart failure, diabetes mellitus, and chronic obstructive pulmonary disease) who enrolls in a coordinated care program after hospital discharge or following a high-risk outpatient visit. The patient is assigned to a care manager within a primary care clinic or an integrated health system for an initial risk-adjusted low intensity coordinated care fee billed with G9004. The clinical workflow begins with a comprehensive intake: medication reconciliation, review of recent hospital/ED use, social needs screen, and formulation of a brief care plan with goals and follow-up schedule. The care manager documents contacts (telephone, telehealth, or face-to-face), coordinates with the primary care provider and any specialists, arranges community resources, and schedules the first follow-up visit. Billing uses G9004 for the initial low-risk adjustment episode; subsequent encounters may use higher risk-adjusted codes if complexity increases. Typical sites of service include outpatient clinics, primary care practices, home visits, and telehealth settings.
