About 95079: Additional oral ingestion challenge time
Reports each additional 60 minutes of supervised oral ingestion challenge testing after the initial challenge period, such as evaluation of suspected food or drug reactions.
This code accounts for additional time spent administering a supervised oral challenge in sequential, incremental doses and observing for a reaction. Allergy specialists commonly use ingestion challenges to assess suspected food allergy or drug allergy, or to determine whether a patient can tolerate a food or medication. The service may take place in an office or facility equipped to monitor the patient during the challenge.
Report 95079 for each additional 60 minutes after the initial ingestion challenge service, and only with the primary challenge code 95076. Documentation should support the challenge items and dose sequence, monitoring and response, and the additional testing time. CMS classifies 95079 as an add-on code: it must be billed with the primary procedure, and its payment is made within that procedure's global period.
