Summary & Overview
HCPCS G9782: Familial Hypercholesterolemia, History or Active Diagnosis
HCPCS Level II code G9782 identifies a history of or active diagnosis of familial hypercholesterolemia (FH). As a documentation code tied to a genetically and clinically significant lipid disorder, it matters nationally for tracking disease prevalence, care coordination, and appropriate use of lipid-lowering therapies and preventive services. Accurate use of G9782 supports risk stratification, population health outreach, and reimbursement workflows for services related to FH management.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how the code is used in clinical documentation and billing, payer coverage considerations, and where it fits into care pathways for lipid disorders. The publication highlights benchmarks and utilization patterns where available, summarizes relevant policy updates affecting documentation and reimbursement for FH-related services, and provides clinical context about why recognizing FH in claims and medical records influences care planning.
This national-level summary is intended for health system administrators, coding and compliance staff, clinicians involved in lipid management, and payer policy teams seeking concise guidance on the role of G9782 in administrative and clinical workflows.
Billing Code Overview
HCPCS Level II code G9782 denotes a history of or active diagnosis of familial hypercholesterolemia. This code is used to document the presence of familial hypercholesterolemia in the patient’s medical record for administrative and billing purposes.
Service Type: Diagnosis documentation / Chronic disease management support
Typical Site of Service: Outpatient clinic or ambulatory care settings, including primary care, cardiology, lipid clinics, and preventive cardiometabolic programs.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a documented personal or family history of high low-density lipoprotein cholesterol and premature atherosclerotic cardiovascular disease who presents for evaluation and management of suspected or confirmed familial hypercholesterolemia. The encounter commonly occurs in an outpatient cardiology, lipidology, endocrinology, or genetic counseling clinic or a specialized preventive cardiology program. Workflow: initial intake includes medication and family history review, focused physical exam for tendon xanthomas or corneal arcus, and review of prior lipid panels. Providers order fasting lipid panel, lipoprotein(a), and secondary cause labs (TSH, liver panel) and may request genetic testing for LDLR, APOB, or PCSK9 variants. Counseling and treatment planning (intensification of statin, addition of ezetimibe, PCSK9 inhibitor consideration, referral for cascade screening) occur in the same visit or via coordinated follow-up. Documentation includes family pedigree, baseline LDL-C values, clinical diagnostic criteria (e.g., DLCN/FH scoring), and informed discussion of pharmacologic and genetic testing options. Typical site of service: outpatient clinic (cardiology, lipid clinic, genetics), infusion center when initiating PCSK9 monoclonal antibody therapy, or telehealth for counseling and follow-up.
