Summary & Overview
HCPCS G9675: History of LDL-C 190 mg/dL
HCPCS Level II code G9675 documents patients who have ever recorded a fasting or direct laboratory LDL-C result of 190 mg/dL. Capturing this high LDL-C level is clinically important because it identifies individuals at markedly elevated risk for atherosclerotic cardiovascular disease and may inform long-term lipid management strategies. Nationally, standardized coding for severe hyperlipidemia supports population health tracking, quality measurement, and care coordination across outpatient and laboratory settings. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical context, typical sites of service, and the relevance of documenting lifetime LDL-C ≥190 mg/dL for care pathways. The publication outlines what to expect in payer coverage considerations and common modifier usage when applicable, and it highlights where input data are not available. This resource is intended to clarify the purpose of G9675, its role in risk stratification, and the types of benchmarks and policy implications that are commonly associated with coding severe hyperlipidemia at a national level.
Billing Code Overview
HCPCS Level II code G9675 identifies patients who have ever had a fasting or direct laboratory result of LDL-C = 190 mg/dL. This code represents a clinical indicator used to capture a history of markedly elevated low-density lipoprotein cholesterol.
Service type: Laboratory/Clinical Risk Identification
Typical site of service: Outpatient clinics, primary care offices, preventive cardiology clinics, and outpatient laboratory settings
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A middle-aged adult is seen in primary care after a routine lipid panel returns a fasting LDL-C of 198 mg/dL. The patient has no prior documented history of markedly elevated LDL-C. The clinician reviews prior laboratory records, confirms a prior direct LDL-C of 190 mg/dL or greater on at least one occasion, documents the laboratory value and date in the chart, and discusses cardiovascular risk and family history. The clinical workflow includes verifying the laboratory source (clinic lab, hospital lab, or reference laboratory), ensuring the fasting status if applicable, reconciling prior lipid panels in the electronic health record, and assigning appropriate problem list entries. Documentation typically includes the numeric LDL-C value (LDL-C = 190 mg/dL or greater), the date of the result, the specimen type (fasting or direct), and clinician interpretation. Billing for the condition-level code G9675 is supported by documentation showing that the patient has ever had a fasting or direct laboratory result with LDL-C = 190 mg/dL or greater; relevant encounters include preventive visits, chronic disease management visits, lipid clinic consultations, or cardiology visits. Typical sites of service are outpatient primary care offices, ambulatory specialty clinics (cardiology, lipidology), and hospital outpatient laboratories where the result is recorded in the medical record.
