CPT Code Overview
CPT code 95180 describes a rapid desensitization procedure, performed each hour, for patients who require urgent tolerance to medications or biological agents such as insulin, penicillin, or equine serum. This service falls under Allergy and Clinical Immunology / Allergen Immunotherapy Services and Procedures. Rapid desensitization is typically provided in settings where immediate medical supervision is available, including the office (POS 11), outpatient hospital (off-campus/on-campus), inpatient hospital, and emergency room environments.

Clinical & Coding Specifications
Clinical Context
A patient with a documented allergy to a medication such as penicillin, insulin, or equine serum presents with a clinical need for that medication due to lack of alternatives. The provider, typically an allergy and immunology physician, initiates a rapid desensitization protocol in a controlled setting such as an office, outpatient hospital, inpatient hospital, or emergency room. The procedure involves administering incremental doses of the allergenic medication over several hours, closely monitoring the patient for adverse reactions. Each hour of the desensitization process is reported using CPT code 95180. The workflow includes pre-procedure assessment, preparation of medication, administration of incremental doses, and continuous monitoring for signs of hypersensitivity or adverse effects.
