CPT® Code 86003

Overview

CPT® Code 86003 is used to report quantitative or semiquantitative measurement of specific IgE antibodies for individual allergens. This test is commonly utilized in the evaluation of allergic conditions, including allergic rhinitis, asthma, atopic dermatitis, and food allergies. Each allergen tested requires a separate 86003 code, allowing clinicians to identify specific sensitivities and guide targeted management.

CPT 86003 represents the laboratory assay itself. Interpretation, patient counseling, or subsequent treatment plans are billed separately.

Key Facts About CPT® 86003

  • Service type: Immunology/allergy laboratory test
  • Provider type: Physicians, allergists, immunologists, and qualified laboratories
  • Medical services included:
    • Quantitative or semiquantitative IgE measurement for a single allergen
    • Reporting of antibody levels with reference ranges
    • Identification of sensitization to specific environmental or food allergens
  • Specimen type: Blood (serum or plasma)
  • Common clinical indications:
    • Diagnosis of allergic rhinitis, asthma, or atopic dermatitis
    • Evaluation of suspected food allergies
    • Monitoring immunotherapy or allergy treatment response
    • Assessment of allergen sensitization patterns for clinical management

When to Use CPT® 86003

CPT 86003 is appropriate when:

  • Blood is collected to measure IgE antibodies for a specific allergen
  • The test is medically necessary to diagnose, monitor, or manage allergic conditions
  • Each allergen tested is billed separately

Examples:

  • Quantitative IgE testing for peanut allergy in a patient with suspected food allergy
  • Environmental allergen testing for dust mites, pollen, and mold spores
  • Monitoring IgE response in a patient undergoing immunotherapy
  • Evaluating multiple allergen sensitivities in a patient with chronic eczema

Documentation Requirements

To properly support CPT 86003 billing, documentation should include:

  • Patient identifiers and date of specimen collection
  • Specific allergen tested and indication for testing
  • Laboratory methodology (quantitative or semiquantitative)
  • Test results, reference ranges, and interpretation
  • Clinical follow-up or management plan based on results

Thorough documentation ensures compliance, medical necessity, and longitudinal tracking of allergic conditions.

Reimbursement and Coding Considerations

  • CPT 86003 is generally covered by Medicare, Medicaid, and commercial insurers when medically necessary
  • Each allergen tested is billed separately; multiple tests require multiple 86003 codes
  • Interpretation, patient counseling, or follow-up treatment is billed separately
  • Always verify payer-specific rules for allergy testing and bundled laboratory services
  • Accurate documentation supports audit readiness and proper reimbursement
