Reader Question: Inpoint Titration Skin Testing

Question: We perform inpoint titration skin testing using 95028 when testing for foods and 95024 for testing inhalants. Is this correct?

Answer: Inpoint titration skin testing is reported 95027 (Skin end point titration) whether the test is for foods or inhalants. This technique is used with immunotherapy to determine a starting point for a patients sensitivity to the allergen (antigen). Generally, three tests (dilutions) per allergen are required to determine the endpoint. These tests are paid per antigen or per stick, depending on the payer. This technique is infrequently used, and many Medicare carriers monitor the use of 95027.

Inpoint titration tests are distinct from intradermal tests, which are reported using 95024 (Intracutaneous [intradermal] tests with allergenic extracts, immediate type reaction, specify number of tests) and 95028 (Intracutaneous [intradermal] tests with allergenic extracts, delayed type reaction, including reading, specify number of tests). Code 95028 describes a delayed identification, meaning the patient would return several days later to obtain the test results.

Medicare carriers accept a limited number of diagnoses to justify billing for 95024, 95027 and 95028. Check your individual carriers local medical review policy (LMRP) for a complete list of applicable ICD-9 codes.
