Why allergy and immunology practices need specialized billing support
Allergy and immunology is a specialized clinical discipline combining complex office consultations with a wide array of diagnostic testing and therapeutic injections. The CPT codes for allergy testing (95000 series) are highly specific, and selecting the correct code requires detailed knowledge of testing methods, antigen counts, and physician attendance requirements. Furthermore, allergy immunotherapy requires precise dose unit coding and preparation documentation to prevent recoupments.
VOPSS provides dedicated allergy and immunology billing specialists who understand the complex rules governing skin testing, patch testing, and immunotherapy. Our team coordinates with your clinic to verify patient eligibility, secure prior authorizations for biologic therapies, and ensure all diagnostic testing is accurately reported.
Common allergy billing errors that impact collections
A frequent source of denials and underpayments in allergy is the incorrect billing of allergy scratch tests (CPT 95004). Claims must report the exact number of test units performed, and failing to document the number of antigens tested results in significant underpayment. Another major challenge is immunotherapy injection billing (95115/95117) and antigen preparation codes (95165).
Prior authorization failures for biologic therapies (such as Xolair, Nucala, Fasenra) represent a substantial financial risk. Since these drugs can cost thousands of dollars per dose, failing to secure an authorization prior to administration results in full claim denial. Additionally, oral food challenges are often underbilled by failing to document the testing duration.

Allergy & Immunology Billing FAQs
How do you code for allergy skin prick testing?
Allergy skin prick testing is coded using CPT 95004 (percutaneous tests with allergenic extracts). It must be billed with the number of units matching the number of antigens tested. For example, if a patient is tested for 40 antigens, CPT 95004 is billed with 40 units. We verify that the medical record documents each antigen tested.
What CPT codes are used for allergy immunotherapy?
Allergy immunotherapy is coded using CPT 95115 for a single injection or 95117 for multiple injections. The preparation of the antigen is billed separately using CPT 95165, which is reported per dose (vial unit). We ensure that the number of doses prepared matches the documentation and that injection administrations are billed on the date they are given.
How do you handle prior authorization for allergy biologics?
We coordinate with major payers and pharmacy benefit managers (PBMs) to secure prior authorizations for all biologic therapies (such as Xolair for chronic urticaria or severe asthma) before the patient's treatment begins. We compile the required clinical documentation (e.g., IgE levels, history of inhaled steroid failure) to ensure authorizations are approved.
What CPT codes are used for oral food challenges?
Oral food challenges are coded using CPT 95076 (first 120 minutes of testing) and CPT 95079 (each additional 60 minutes). We ensure that the documentation clearly specifies the start and stop times of the challenge to justify the code selection.
