What This Code Means

An allergic skin reaction that develops from direct contact with food items on the skin, such as citrus fruits, shellfish, or other food allergens.

Coding Tips

  • •Document the specific food causing the reaction to help the patient avoid contact and identify potential oral allergy risks
  • •Distinguish from oral allergic reactions or systemic food allergies, which would be coded differently

Excludes 2 — Not included here, may code separately
