Intracutaneous (intradermal) tests are diagnostic procedures used to assess an individual's sensitivity to specific allergens. These tests involve the administration of allergenic extracts, which are substances derived from potential allergens, injected just beneath the surface of the skin. The primary purpose of these tests is to provoke a delayed type allergic reaction, which typically manifests over a period of several days. During the procedure, one or more allergenic extracts are carefully selected and documented, ensuring that the specific allergens being tested are clearly identified. Patients are provided with detailed instructions regarding the expected outcomes of a delayed type reaction, including the timeline for when they should return for evaluation. Generally, patients are asked to return to the healthcare facility approximately 48 hours after the initial injection. At this follow-up visit, a physician or qualified healthcare professional examines the injection sites to assess for any signs of allergic reactions, such as redness, swelling, or inflammation. The results of the test are then interpreted, and a comprehensive written report is generated, detailing the presence, absence, or degree of allergic reaction to each allergen tested. This structured approach ensures that the testing process is thorough and that the results are clearly communicated to the patient and relevant healthcare providers.

Intracutaneous (intradermal) tests with allergenic extracts are indicated for the evaluation of suspected allergies, particularly when a delayed type reaction is anticipated. These tests are commonly performed in the following scenarios:
The procedure for conducting intracutaneous tests with allergenic extracts involves several key steps to ensure accurate results and patient safety.
After the intracutaneous testing procedure, patients are advised to monitor the injection sites for any unusual reactions and to report any significant changes or discomfort to their healthcare provider. The expected recovery period is generally short, with most patients experiencing minimal discomfort at the injection sites. Follow-up appointments may be scheduled to discuss the results of the test and to develop an appropriate management plan based on the identified allergens. It is essential for patients to adhere to the follow-up instructions to ensure comprehensive evaluation and care.

| XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | 25 | Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59. | GC | This service has been performed in part by a resident under the direction of a teaching physician | GZ | Item or service expected to be denied as not reasonable and necessary |
