Summary & Overview
HCPCS G1009: Clinical Decision Support Mechanism (Sage Health Management Solutions)
HCPCS Level II code G1009 documents the use of a clinical decision support mechanism from Sage Health Management Solutions, aligned with the Medicare Appropriate Use Criteria program. Nationally, this code captures adoption of point-of-care, evidence-based guidance tools that aim to standardize imaging and procedure ordering, support clinical decision-making, and demonstrate compliance with federal appropriate use initiatives.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose, service context, and payer coverage patterns. The publication outlines benchmarks where available, recent policy and billing guidance relevant to decision support reporting, and the clinical context for when such mechanisms are used during outpatient ordering workflows.
This summary provides practical reference for coding teams, compliance officers, and practice managers seeking a national-level view of G1009, its intended service, and the areas to monitor for payer-specific guidance and reporting requirements.

Clinical & Coding Specifications
Clinical Context
The patient is a 67-year-old man with known coronary artery disease presenting to an outpatient cardiology clinic for evaluation of new-onset chest pain prior to planned elective coronary imaging. The clinician intends to order an advanced imaging test (e.g., coronary CT angiography or nuclear stress imaging). As part of the Medicare Appropriate Use Criteria (AUC) program workflow, the clinic uses a Clinical Decision Support Mechanism (CDSM) — in this case, a vendor such as Sage Health Management Solutions — to determine whether the proposed imaging study meets appropriate use criteria.
The workflow proceeds as follows: the ordering clinician enters the planned imaging study and the patient’s clinical data into the electronic health record. The EHR invokes the CDSM and sends the pertinent clinical indications. The CDSM returns an appropriateness determination (e.g., appropriate, may be appropriate, or rarely appropriate) along with guidance. The clinician documents the CDSM response and proceeds with ordering the test if clinically indicated. Billing for the CDSM interaction is reported using the HCPCS Level II code G1009 when the mechanism is the Sage Health Management Solutions clinical decision support tool as defined by the Medicare AUC program. Typical site of service is outpatient clinics, hospital outpatient departments, and ambulatory imaging centers. Typical patient scenarios include pre-imaging evaluation for cardiovascular imaging, musculoskeletal advanced imaging, or other advanced diagnostic imaging where AUC applies.
