Summary & Overview
HCPCS G1007: Clinical Decision Support Mechanism for Specialty Health
HCPCS Level II code G1007 designates a clinical decision support mechanism focused on specialty care within the Medicare Appropriate Use Criteria program. Nationally, such mechanisms are increasingly important as payers and regulators emphasize evidence-based ordering to reduce unnecessary testing and improve care coordination. The code signals the provision of specialty-specific decision support tools or services that inform appropriate use of diagnostic tests or specialty procedures.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise context on the code’s clinical purpose, typical settings where the service is delivered, and what is commonly reported with the code. The publication covers practical benchmarks and policy context where available, explains common billing modifiers and payer coverage patterns, and outlines the clinical scenarios that drive use of specialty decision support.
This summary is intended to orient clinicians, billing staff, and policy analysts to the role of G1007 in specialty care workflows and payer interactions. Data not available in the input is noted in relevant sections.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with multiple cardiovascular risk factors is scheduled for an outpatient advanced imaging study (such as CT angiography or nuclear stress testing) to evaluate chest pain. Prior to ordering the advanced imaging, the ordering clinician uses an electronic Clinical Decision Support (CDS) mechanism aligned with the Medicare Appropriate Use Criteria (AUC) program to determine appropriateness. The CDS tool requires the clinician to enter the suspected clinical indication, relevant signs/symptoms, prior test results, and current medications. The CDS returns an appropriateness determination (e.g., appropriate, may be appropriate, not appropriate) and documents the rationale in the electronic health record. The ordering clinician reviews the CDS recommendation, documents acknowledgement or override, and proceeds with scheduling the imaging when indicated. Typical workflow involves: initial patient evaluation in clinic or the emergency department, use of the CDS tool at the point of order entry, capture of the AUC determination for Medicare reporting, and transmission of the order to outpatient imaging services or hospital radiology. Common sites of service include outpatient imaging centers, hospital outpatient departments, and emergency departments.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for the billed service due to complexity of CDS documentation or extended justification for appropriateness. |
