CPT® Code 95044

Patch testing, as described by CPT® Code 95044, is a diagnostic procedure used to identify contact allergies that may lead to dermatitis. This method involves the application of allergenic extracts to the skin, allowing healthcare professionals to assess the patient's sensitivity to various substances. Typically, between 20 to 30 different allergens are tested simultaneously. The patches containing these allergens are affixed to the patient's skin, usually on the arm or back, and are left in place for a duration of 48 hours. During this time, it is crucial for the patient to avoid activities that may compromise the integrity of the test, such as bathing or engaging in strenuous physical activities that could induce sweating. After the 48-hour period, the patient returns to the healthcare facility where the patches are carefully removed. The physician or qualified healthcare professional then examines the skin for any signs of allergic reactions, which may include redness, swelling, or inflammation. The findings from this examination are documented in a written report that details the presence, absence, or degree of any allergic reactions to each specific allergen tested, providing valuable information for the management of the patient's allergic conditions.
