Summary & Overview
HCPCS G9061: Oncology Guidance When Guidelines Do Not Apply
HCPCS Level II code G9061 denotes oncology practice guidance used when a patient’s condition is not addressed by existing clinical practice guidelines; it is designated for use in a Medicare-approved demonstration project. Nationally, the code signals scenarios where standard guidance is insufficient and additional review or specialized decision-making is documented. That context matters for payers and providers managing complex oncology cases and for programs testing alternative care pathways.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical intent and operational context, an overview of payer coverage considerations, and what stakeholders typically monitor around demonstration-project codes: eligibility criteria for the demonstration, documentation expectations, and how services are categorized for claims processing.
This publication provides benchmarks and policy context relevant to national stakeholders, outlines typical sites of service where the code is applied, and highlights implications for coding workflows and claims review. Data not available in the input is noted where applicable; the focus remains on clarifying the code’s purpose and practical considerations for payer and provider audiences.
Billing Code Overview

The code is intended for use within a Medicare-approved demonstration project and captures instances in which standard oncology practice guidelines are insufficient to guide care decisions.
Service type: Oncology clinical guidance/decision support when guidelines are inadequate.
Typical site of service: Oncology clinic, hospital outpatient department, or other settings where oncology care and multidisciplinary guideline review occur.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with metastatic colorectal cancer enrolled in a Medicare-approved oncology demonstration project presents for an oncology practice-guideline review because their clinical situation is not addressed by available guidelines. The patient has progressed after standard first- and second-line therapies and demonstrates a rare molecular profile with limited evidence for guideline-driven management. The oncology team documents multidisciplinary case review, review of literature, and individualized care planning to support medically necessary decision-making under the demonstration project. Use of G9061 is reported when the clinician documents that available national or specialty oncology practice guidelines do not address the patient’s unique clinical presentation, and the service is rendered as part of the demonstration project. Typical workflow includes chart review, tumor board or multidisciplinary consultation, documentation of why established guidelines are not applicable, development of an individualized plan of care, and billing under the demonstration project with appropriate modifier and supporting ICD-10 diagnosis codes for the patient’s malignancy and relevant complications.
