Summary & Overview
CPT 83719: Direct Very Low Density Lipoprotein (VLDL) Cholesterol Measurement
CPT code 83719 represents a laboratory assay for the direct measurement of very low density lipoprotein (VLDL) cholesterol in a patient specimen. Direct VLDL cholesterol measurement provides clinicians with a specific lipid fraction that can inform cardiovascular risk assessment and lipid management strategies. As laboratory testing evolves, distinct codes like 83719 matter for accurate procedure reporting, clinical clarity, and payer adjudication across the country.
Key national payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication offers a concise overview of clinical context, coding implications, and the types of benchmarks and payment policy topics readers can expect to find. Topics include typical sites of service and clinical indications for ordering a direct VLDL cholesterol test, summary benchmark concepts for laboratory reimbursement, and relevant policy considerations that affect coverage and billing processes.
Readers will gain a clear understanding of what CPT code 83719 captures, how it fits within lipid testing services, and which payers commonly process claims for this assay. The content also summarizes available national payer considerations and notes where input data was not provided, helping billing managers, laboratory administrators, and policy analysts locate the information they need for coding and claim submission workflows.
Billing Code Overview
CPT code 83719 describes a laboratory procedure in which a lab analyst directly measures very low density lipoprotein (VLDL) cholesterol in a patient specimen. This is a clinical chemistry test that quantifies VLDL cholesterol concentration, providing specific lipid fraction information beyond standard lipid panels.
Service Type: Laboratory — Direct VLDL Cholesterol Measurement
Typical Site of Service: Clinical laboratory or hospital laboratory

Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with mixed dyslipidemia and metabolic syndrome presents for cardiovascular risk assessment and lipid management follow-up. The clinician orders a direct VLDL cholesterol measurement because the patient has a history of hypertriglyceridemia (>200 mg/dL) and concurrent conditions that can alter calculated lipid fractions (recent non-fasting specimen, diabetes mellitus with poor control, or use of lipid-altering medications). A phlebotomist collects a serum specimen in an outpatient clinic or ambulatory laboratory; the sample is labeled and transported to the clinical chemistry laboratory. A laboratory analyst performs the direct measurement of very low density lipoprotein cholesterol using an approved analytic method. Results are entered into the laboratory information system and routed to the ordering provider. The clinician reviews the 83719 result alongside a lipid panel to guide medication adjustments, risk stratification, or further testing such as apolipoprotein B or advanced lipoprotein testing.
