Summary & Overview

HCPCS G9365: One High-Risk Medication Ordered

HCPCS Level II code G9365 denotes the ordering of one high-risk medication and is used to identify instances where a patient is prescribed or managed on a medication with elevated safety considerations. Nationally, tracking use of this code supports oversight of medication safety programs, informs utilization management, and aids in quality measurement related to high-risk therapies. The code is relevant across payer types, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of payer coverage patterns, common clinical contexts for use, and benchmarks where available. The publication summarizes how G9365 is recorded across payers, outlines service line and site-of-service implications for inpatient and outpatient settings, and highlights policy or billing considerations that affect coding consistency. Where input data is missing, the report notes that elements such as associated taxonomies, ICD-10 pairings, and related codes are not available in the input.

Clinical & Coding Specifications

Clinical Context

A hospitalized adult patient with complex chronic conditions is prescribed a medication classified as high-risk due to narrow therapeutic index, potential for severe adverse events, or need for intensive monitoring. Examples include anticoagulants (e.g., warfarin), certain antiarrhythmics, immunosuppressants, or high-alert oncology agents. A clinician (hospitalist, inpatient pharmacist, or prescriber) orders the single high-risk medication during admission or at transition of care. The medication order triggers clinical pharmacy review, dosing verification, allergy and interaction checks, and monitoring plan documentation. Typical workflow steps: medication order entry in the electronic health record, pharmacist verification, bedside administration by a licensed nurse with independent double-checks when required, laboratory monitoring orders placed as indicated (e.g., INR, drug levels), and documentation of counseling or care coordination if outpatient therapy will continue. The service is typically reported when a discrete additional safety or verification service is provided specifically for one high-risk medication during an encounter.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when work required to manage or verify the high-risk medication substantially exceeds usual; document rationale and time.
`23`	Unusual anesthesia	Not typically applicable to medication ordering; do not apply unless anesthesia services are separately involved for medication administration.
`52`	Reduced services	Use if the verification or monitoring service for the high-risk medication was partially reduced or abbreviated.
`53`	Discontinued procedure	Use if the medication verification service was started but discontinued due to patient factors before completion.
`54`	Surgical care only	Not applicable to medication-only verification services; exclude unless part of a bundled surgical episode.
`55`	Postoperative management only	Not applicable unless the high-risk medication management is provided exclusively in the postoperative period and billed separately.
`56`	Preoperative management only	Use when the service is limited to preoperative high-risk medication planning (e.g., perioperative anticoagulation plan).
`62`	Two surgeons	Rarely applicable; do not apply unless two separate qualified providers each perform distinct verification tasks qualifying under this service.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery	Not applicable for typical medication verification; do not use unless specific assistant-at-surgery context exists.
`CO`	Outsourced clinical laboratory	Use when laboratory testing required for drug monitoring is performed by an outside clinical laboratory and payor requires modifier reporting.
`CQ`	Service furnished by a registered nurse practitioner in a Federally Qualified Health Center	Use when applicable to the billing rules for the site and provider taxonomy performing the medication-related service.
`FX`	Primary surgeon changed to another surgeon due to emergency	Not applicable to medication verification services.
`FY`	Primary surgeon changed to assistant surgeon due to emergency	Not applicable to medication verification services.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures	Not applicable to medication verification services.
`QX`	CRNA service with medical direction	Not applicable unless anesthesia personnel are directly involved in medication administration.

Taxonomy Code	Specialty	Notes
`2080S0102X`	Hospitalist	Primary inpatient physicians ordering and coordinating high-risk medications.
`333600000X`	Clinical Pharmacist	Pharmacists who perform medication verification, reconciliation, and monitoring for high-risk agents.
`207Q00000X`	Internal Medicine	Specialists managing complex medical conditions requiring high-risk medications.
