CPT® Code 86001 is used to report laboratory testing for allergen-specific Immunoglobulin G (IgG), either quantitatively or semi-quantitatively, for a single allergen. This test measures the patient’s IgG antibody response to specific allergens, which can help evaluate immune response patterns, monitor exposure, or support clinical decision-making in allergy management.
Each allergen tested is reported separately, and the test can be performed on serum or plasma specimens.
Key Facts About CPT® 86001
Service type: Laboratory serologic test
Provider type: Physicians, allergists, immunologists, and qualified laboratory personnel
Medical services included: Yes—quantitative or semi-quantitative measurement of IgG antibodies to a specific allergen
Specimen type: Serum or plasma
Test method: Immunoassay or other validated serologic techniques
Common clinical indications:
- Monitoring immune response to specific allergens
- Supporting allergy management or desensitization protocols
- Assessing dietary or environmental allergen exposure
- Evaluating patient response to allergen avoidance or immunotherapy
- Research or clinical studies related to allergen-specific IgG levels
When to Use CPT® 86001
CPT 86001 is appropriate when:
- A quantitative or semi-quantitative IgG test is performed for each specific allergen
- The test is medically necessary for monitoring, research, or clinical management
- Specimens are collected and processed according to laboratory standards
- Results are used to guide clinical recommendations, such as diet, avoidance strategies, or immunotherapy
Examples:
- Measuring IgG response to a single food allergen in a patient undergoing dietary evaluation
- Testing for environmental allergen-specific IgG to support desensitization therapy
- Monitoring IgG levels in a patient following allergen exposure or avoidance measures
- Performing a research-based evaluation of IgG antibodies to a specific pollen allergen
Documentation Requirements
To support CPT 86001 billing, documentation should include:
- Patient identifiers and date of service
- Allergen tested
- Test method (quantitative or semi-quantitative)
- Specimen type and collection date
- Clinical indication or medical necessity
- Test results and interpretation
- Ordering provider credentials and signature
- Laboratory performing the test
Complete documentation ensures coding accuracy, reimbursement, and clinical utility.
Reimbursement and Coding Considerations
- CPT 86001 is billed per allergen tested
- Quantitative or semi-quantitative methods must be documented
- Coverage depends on medical necessity, payer guidelines, and test purpose
- Multiple allergens require multiple units of CPT 86001
- Ensure compliance with laboratory testing and billing regulations
Accurate coding and thorough documentation reduce claim denials and support proper reimbursement.
