Summary & Overview
CPT 0052U: VAP Cholesterol Test, High-Resolution Lipoprotein Fractionation
CPT code 0052U designates the VAP® Cholesterol Test, a Proprietary Laboratory Analyses (PLA) assay that performs high-resolution lipoprotein fractionation and quantitative measurement of a comprehensive lipoprotein panel. The code represents a specialized laboratory service focused on detailed cardiovascular risk markers beyond standard lipid testing, including subclass breakdowns for HDL, LDL, and VLDL as well as lipoprotein(a) and IDL. Nationally, PLA codes like 0052U matter because they identify manufacturer- or lab-specific assays whose use can affect coverage, claim adjudication, and data comparability across payers.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for advanced lipoprotein testing, common billing and service characteristics for this laboratory assay, and the payer landscape relevant to proprietary tests. The publication summarizes where 0052U fits in laboratory service lines, clarifies typical sites of service and the nature of the assay, and outlines which payers are part of the coverage and billing discussion. Data not provided in the input for specific reimbursement benchmarks, modifiers usage patterns, and mappings to diagnosis codes are noted as unavailable.
Billing Code Overview
CPT code 0052U is a Proprietary Laboratory Analyses (PLA) code for the VAP® Cholesterol Test by VAP Diagnostics Laboratory, Inc. The test uses high-resolution lipoprotein fractionation to measure a detailed lipoprotein profile in a patient blood specimen, including total lipoprotein, high-density lipoprotein (HDL), low-density lipoprotein (LDL), very–low–density lipoprotein (VLDL), lipoprotein(a) (Lp(a)), intermediate–density lipoprotein (IDL), HDL subclasses (HDL2 and HDL3), LDL subclasses (LDL1, LDL2, LDL3, LDL4), and VLDL subclasses (VLDL1, VLDL2, VLDL3).
Service type: Laboratory — Proprietary high-resolution lipoprotein fractionation and quantitative lipoprotein analysis.
Typical site of service: Clinical laboratory or independent reference laboratory.
Data not available in the input for associated taxonomies, ICD-10 diagnoses, related codes, and service line.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with mixed dyslipidemia and a family history of premature coronary artery disease presents for cardiovascular risk assessment after statin therapy produces borderline LDL changes. The clinician orders the VAP® Cholesterol Test (0052U) to obtain high-resolution lipoprotein fractionation. A blood specimen is collected in an outpatient phlebotomy clinic or hospital laboratory, labeled, and shipped per the laboratory’s specimen requirements. The VAP test returns detailed measures including total lipoprotein, HDL, LDL, VLDL, Lp(a), IDL, HDL2/HDL3, LDL1–LDL4, and VLDL1–VLDL3. Results are reviewed by the ordering clinician during the follow-up visit to refine cardiovascular risk stratification and to guide lipid-targeted therapy adjustments. Typical sites of service include outpatient hospital labs, independent reference laboratories, and ambulatory clinic phlebotomy suites.
