Encounter for allergy testing

This code signifies an encounter where a patient is undergoing testing to identify specific allergens that may be causing an allergic reaction. This typically involves skin prick tests, patch tests, or in-vitro blood tests to detect sensitivities to various substances. The purpose is to pinpoint the triggers for allergic symptoms.

Use this code when a patient presents for allergy testing due to suspected allergies, such as environmental, food, or drug allergies. It is appropriate for initial diagnostic workups to identify allergens or for follow-up testing to confirm or re-evaluate sensitivities. This code is used when the primary reason for the visit is the allergy testing itself.

• Do not use this code if the encounter is for antibody response examination, even if related to an immune response.
• Always code the specific allergy symptoms or conditions (e.g., allergic rhinitis, asthma) as additional diagnoses if they are present and being managed.
• Ensure documentation clearly supports the reason for the allergy testing, such as patient history of allergic reactions or suspected triggers.
