Need for desensitization to allergens

This code signifies a patient's requirement for treatment aimed at reducing their sensitivity to specific allergenic substances. It indicates that the patient is undergoing or has been identified as needing immunotherapy to mitigate allergic reactions.

This code is appropriate for patients receiving allergen immunotherapy (e.g., allergy shots or sublingual immunotherapy) or those who have been evaluated and recommended for such treatment due to documented allergies. It is used to indicate the underlying reason for the desensitization process.

• Always code the specific allergy (e.g., allergic rhinitis, asthma due to pollen) in conjunction with this code.
• Do not use this code for acute allergic reactions or for prophylactic medication management without an active desensitization program.
• This code is for the need for desensitization; use procedure codes for the actual administration of immunotherapy.
