Summary & Overview

HCPCS G1017: Clinical Decision Support Mechanism (healthhelp)

HCPCS Level II code G1017 identifies a clinical decision support mechanism branded as healthhelp under the Medicare Appropriate Use Criteria program. The code documents use of an electronic decision-support tool that delivers point-of-order guidance to clinicians to help align imaging and other orders with evidence-based criteria. Nationally, this code matters as policy expands requirements for electronic appropriate-use tools and as payers evaluate workflows and documentation standards tied to ordering behavior.

Key payers examined in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise reference to the clinical role of the code, the typical sites of service where the mechanism is used, and what to expect for documentation and coding practice. The publication also covers benchmark expectations, relevant policy context tied to the Appropriate Use Criteria program, and practical clinical context for how such decision-support mechanisms integrate into ordering workflows.

This summary provides national-level guidance on the purpose and scope of G1017, orientation to payer coverage landscape, and an outline of topics addressed in the full publication: benchmarks, policy updates, and clinical implementation considerations. Data not available in the input are noted where applicable in detailed sections.

Billing Code Overview

HCPCS Level II code G1017 denotes a clinical decision support mechanism identified as healthhelp, defined by the Medicare Appropriate Use Criteria program. The code represents the use of an electronic decision support tool that provides point-of-order guidance to clinicians to support appropriate use of advanced imaging and other services under the Appropriate Use Criteria framework.

Service Type: Clinical decision support (electronic decision support mechanism)

Typical Site of Service: Hospital outpatient departments, physician offices, and other locations where ordering clinicians access electronic clinical decision support at the point of order

Clinical & Coding Specifications

Clinical Context

A patient presents to an outpatient radiology clinic or hospital imaging center for imaging of suspected acute or chronic cardiopulmonary or musculoskeletal conditions where advanced imaging orders require confirmation of adherence to Appropriate Use Criteria (AUC). The ordering clinician (for example, an emergency physician, primary care physician, or cardiologist) requests an advanced imaging study such as CT, MRI, or nuclear medicine. Before the imaging is scheduled or performed, a clinical decision support mechanism is queried to evaluate the requested imaging against Medicare Appropriate Use Criteria. The decision support system generates guidance indicating whether the ordered study is appropriate, may be appropriate, or is rarely appropriate based on the documented clinical indication and available patient data. The imaging facility documents the interaction and the AUC response when billing the service represented by G1017. Typical workflow steps:

The ordering clinician documents the clinical indication in the electronic health record and initiates an imaging order.
The electronic health record sends the order details to the clinical decision support mechanism implementing AUC logic.
The decision support mechanism evaluates the indication and returns an AUC determination and rationale.
The ordering clinician reviews the AUC output and either proceeds, modifies, or cancels the imaging order; the AUC interaction is recorded in the patient record.
When applicable, the facility bills G1017 to report the use of a clinical decision support mechanism under the Medicare Appropriate Use Criteria program. Typical sites of service include outpatient hospital imaging departments, freestanding imaging centers, and emergency departments.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when the decision support interaction required substantially greater resources or documentation than typical (rare for `G1017`).
`23`	Unusual anesthesia	Not commonly used with `G1017`; include only if anesthesia-related atypical circumstances are documented.
`52`	Reduced services	Use if the full decision support process was partially completed or truncated.
`53`	Discontinued procedure	Use if the AUC process was initiated but stopped prior to producing a determination.
`54`	Surgical care only	Not typically applicable to `G1017`; include only if billing separation requires.
`55`	Postoperative management only	Not typically applicable to this code.
`56`	Preoperative management only	Use if the AUC interaction was limited to preoperative imaging decision support that did not include subsequent imaging.
`62`	Two surgeons	Rarely applicable; use only when dual-surgeon billing context affects related imaging services.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery	Not routinely used for `G1017`; include only if procedural assistance documentation impacts billing relationships.
`CQ`	Service furnished by a physical therapist in a facility setting	Not applicable to `G1017` except in unusual multidisciplinary workflows.
`QK`	Medical direction of two, three, or four assistants	Use only if assistant-related supervision context affects associated imaging procedures.
`QX`	CRNA service independently performed	Not applicable to `G1017` except in rare facility billing interactions.
`QY`	Medical direction of one CRNA by an anesthesiologist	Not applicable to `G1017` except in rare related procedural billing.
`FX`	Unplanned return to the operating room	Not applicable to `G1017`.

`208D00000X`	Diagnostic Radiology	Diagnostic radiologists interact with decision support outputs to guide imaging protocols and justification.
`207L00000X`	Emergency Medicine	Emergency physicians commonly use AUC decision support for emergent imaging orders.
`207Q00000X`	Family Medicine	Primary care physicians utilize AUC tools when ordering outpatient advanced imaging.

`R06.02`	Shortness of breath	Respiratory complaints lead to chest imaging decisions where AUC determines need for CT angiography, chest CT, or chest x‑ray.
`G89.29`	Other chronic pain	Chronic pain presentations may generate imaging requests (e.g., spine MRI) where AUC evaluates appropriateness based on history and exam.
