Oth allergy status, oth than to drugs and biolg substances

This code indicates a patient's documented history of an allergic reaction to a substance that is not a medication or a biological product. It signifies a known sensitivity to environmental factors, foods, or other non-drug/non-biological agents that could trigger an adverse immune response. This status is important for preventing future exposures and guiding treatment decisions.

Apply this code when a patient has a history of allergies to substances like specific foods (e.g., peanuts, shellfish, gluten), insect stings (e.g., bee venom), latex, or environmental allergens (e.g., pollen, dust mites, pet dander). It is used to document the patient's allergic status for conditions not covered by more specific Z codes for drug or biological allergies.

• Always seek documentation of the specific allergen if available, even if not coded separately.
• Do not use this code for current allergic reactions; use codes from Chapter 12 (Diseases of the Skin and Subcutaneous Tissue) or Chapter 10 (Diseases of the Respiratory System) for active allergic manifestations.
• This is a "status" code, indicating a historical condition, and is typically used as a secondary diagnosis to provide additional patient information.
