Summary & Overview
CPT 86003: Allergen-Specific IgE Assay, Technical Component
CPT code 86003 represents the technical component of a laboratory assay that measures allergen-specific immunoglobulin E (IgE) using crude allergen extracts. This code is used per crude extract tested and yields quantitative or semiquantitative results. Nationally, allergen-specific IgE testing informs diagnosis and management of allergic conditions and supports clinical decision-making across primary care, allergy/immunology, and inpatient settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of code usage and clinical context, common payer coverage patterns, and practical billing considerations related to reporting the technical component per extract. The publication outlines where this service is typically performed (clinical or hospital laboratories) and clarifies that each crude allergen extract requires a separate unit of the code.
This summary provides benchmarks for code utilization, discusses relevant policy or coding updates where applicable, and situates 86003 within laboratory service lines for allergy testing. Data not provided in the input are noted as such in the detailed sections.
Billing Code Overview
CPT code 86003 describes a laboratory test in which a lab analyst performs the technical component to measure allergen-specific immunoglobulin E (IgE) in a specimen such as serum using a crude allergen extract. The result is quantitative or semiquantitative, and each crude allergen extract tested is reported with a single unit of this code.
Service type: Laboratory diagnostic testing (allergen-specific IgE assay, technical component)
Typical site of service: Clinical laboratory or hospital laboratory
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient with seasonal allergic rhinitis and suspected sensitization to tree pollen presents to an outpatient allergy clinic. The allergist orders serum allergen-specific IgE testing to quantify sensitization to multiple crude allergen extracts. A phlebotomy technician collects a blood specimen in the clinic; the specimen is sent to the reference laboratory. In the lab, a clinical laboratory scientist performs the technical assay using a crude allergen extract to measure allergen-specific immunoglobulin E. Each individual crude allergen extract tested is billed as a single unit of 86003. Results are reported as quantitative or semiquantitative IgE levels to guide clinical interpretation for avoidance measures, pharmacotherapy, or consideration of immunotherapy.
