Event Date: Wednesday, May 06, 2026 | Time: 1 pm ET | 12 pm CT | 11 am MT | 10 am PT | Duration: 60 minutes

Webinar Description:

Allergy testing and immunotherapy services are highly scrutinized by payers due to complex coding rules, strict documentation requirements, and frequent audit activity. This in-depth webinar is designed to provide billing professionals, coders, practice managers, and clinical staff with a clear, practical understanding of how to accurately code, document, and bill allergy testing and treatment services in a compliant manner.

The session begins with an overview of common allergy testing and treatment modalities, including skin prick testing, intradermal testing, patch testing, and serum (IgE) testing. Participants will also review the core components of allergy immunotherapy, including subcutaneous immunotherapy (SCIT), antigen preparation, and injection administration. Special emphasis will be placed on understanding per-test, unit-based, and time-based billing methodologies.

Attendees will learn how to correctly assign codes for allergy testing, immunotherapy injections, and antigen preparation. The webinar will outline essential documentation elements needed to support medical necessity, test performance, results, and immunotherapy administration, ensuring records are audit-ready.

Common billing and coding errors, bundling rules, and payer expectations will be reviewed, along with high-risk audit red flags.
