Summary & Overview
HCPCS G9366: One High-Risk Medication Not Ordered
HCPCS Level II code G9366 denotes a clinical decision in which one high-risk medication was not ordered. This code captures instances where prescribers identify potential medication-related harm and document the choice not to initiate a particular high-risk drug. Nationally, coding for omission of high-risk medications supports patient safety tracking, quality measurement, and payer reporting related to medication management.
Key payers included in typical analyses are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise understanding of what G9366 represents, why documenting withheld high-risk medications matters for safety and quality programs, and the clinical contexts in which it is used. The publication outlines common benchmarks and reporting uses, summarizes policy and coverage considerations affecting documentation and claims, and provides clinical context for when the code is applicable.
Where data elements are not present in the source input, the publication notes those gaps. The content is national in scope and focuses on the code’s purpose, documentation implications, and how it fits into medication management and quality reporting workflows.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult aged 65 with multiple chronic conditions who presents for medication reconciliation during a primary care or transitional care visit. The clinician identifies a prescribed high-risk medication (for example, a benzodiazepine, long-acting opioid, or anticholinergic in an older adult) and documents that the medication was not ordered or was intentionally discontinued because risks outweigh benefits. The workflow includes: medication review in the electronic health record, assessment of risk factors (falls, cognitive impairment, renal impairment), shared decision-making documentation, an updated medication list, and communication of the change in the after-visit summary and to the dispensing pharmacy if applicable. Typical sites of service are outpatient primary care clinics, transitional care management visits, nursing facility rounds, and home health visits where medication review occurs but the high-risk medication is specifically not ordered.
