HCPCS G9442: Statin Not Prescribed for Documented Reasons - OpenPayer

Summary & Overview

HCPCS G9442: Statin Not Prescribed for Documented Reasons

HCPCS Level II code G9442 represents documentation that a statin was not prescribed for a patient due to documented reasons such as allergy or medical intolerance. This code captures a specific clinical decision point relevant to cardiovascular preventive care and medication safety, enabling clinicians and payers to distinguish appropriate non-prescription from under-treatment. Nationally, proper use of this code supports quality measurement, continuity of care, and accurate attribution for performance metrics around statin therapy.

Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context in which G9442 is used, typical sites of service, and how the code fits into documentation and quality measurement workflows. The publication also outlines benchmarks and policy considerations relevant to national payer programs and government coverage, plus practical notes on where to expect this code to appear in claims and medical records.

The piece is designed for clinicians, coding professionals, and policy analysts seeking a concise reference for G9442, including implications for quality reporting and the clinical documentation needed to support the code. Data not available in the input.

Billing Code Overview

HCPCS Level II code G9442 indicates statin not prescribed for documented reasons (e.g., allergy, medical intolerance). The code documents clinical situations in which a statin medication was considered but not prescribed because of a documented contraindication, allergy, or intolerance.

Service type: Medication management / clinical decision documentation

Typical site of service: Outpatient clinical settings, including primary care clinics, cardiology clinics, and other ambulatory care environments where preventive cardiovascular medication decisions are made.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 68-year-old with a history of atherosclerotic cardiovascular disease (ASCVD) who presents for a routine cardiovascular risk follow-up. The clinician documents that statin therapy is indicated based on age, prior myocardial infarction, or ischemic stroke, but a statin is not prescribed because of a documented, clinically significant reason (for example, a confirmed severe allergic reaction to multiple statins, recurrent statin-associated myopathy with persistent elevated creatine kinase, or a clear medical intolerance such as severe liver injury temporally related to statin use). The clinical workflow includes a focused medication reconciliation, review of prior adverse drug reactions and laboratory data (liver function tests, creatine kinase), documentation of the contraindication or intolerance in the medical record, discussion of alternative lipid-lowering strategies, and coding the encounter using the HCPCS Level II code G9442 to indicate that a statin was not prescribed for documented reasons. Typical sites of service include outpatient primary care clinics, cardiology clinics, geriatric medicine clinics, and outpatient specialty clinics where chronic cardiovascular risk management occurs. Typical accompanying services include medication counseling, laboratory ordering, and referral planning for alternative therapies or specialist evaluation.

`207Q00000X`	Family Medicine	Primary care clinicians commonly document medication intolerance and manage ASCVD risk.
`207R00000X`	Internal Medicine	Internists frequently manage chronic lipid disorders and document statin contraindications.
`207RC0000X`	Cardiology	Cardiologists document statin intolerance when managing secondary prevention in ASCVD.
`207V00000X`	Geriatric Medicine	Geriatricians often evaluate medication tolerability in older adults and document non-prescription decisions.
`363LF0000X`	Clinical Pharmacology	Clinical pharmacists may document adverse drug reactions and contribute to medication management notes.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`I25.10`	Atherosclerotic heart disease of native coronary artery without angina pectoris	Indicates ASCVD where statin therapy is generally indicated but may be withheld for documented reasons.
`I63.9`	Cerebral infarction, unspecified	Ischemic stroke history supports secondary prevention with statins; documentation of intolerance justifies `G9442`.
`E78.0`	Pure hypercholesterolemia	Primary hyperlipidemia diagnosis where statin therapy is a first-line treatment; `G9442` documents why statin was not prescribed.
`M79.1`	Myalgia	Muscle symptoms that may represent statin-associated myopathy and justify documenting statin intolerance.
`K71.6`	Toxic liver disease with hepatic necrosis	Severe liver injury that may contraindicate statin use and support `G9442` coding.
`T88.1XXA`	Other complications following infusion, transfusion and therapeutic administration, initial encounter	Used if an adverse drug reaction to a statin is documented as a complication requiring documentation of non-prescription.
`Z88.0`	Allergy status to penicillin (example allergy code format)	Allergy coding framework; when a documented allergy to statins exists, the appropriate statin allergy code should be used alongside `G9442`.
