About coding Poison ivy
The ICD-10-CM code for Poison ivy is L23.7 (Allergic contact dermatitis due to plants, except food).
Within L23 (allergic contact dermatitis), L23.7 is specifically for allergic contact dermatitis due to plants, except food. Related codes cover due to metals (L23.0), due to adhesives (L23.1), due to cosmetics (L23.2), due to drugs in contact with skin (L23.3), due to dyes (L23.4), due to other chemical products (L23.5), due to food in contact with the skin (L23.6), due to other agents (L23.8) and 1 more.
The conditions in its Excludes2 note aren't part of L23.7, but may be coded alongside it if the patient has both: allergy NOS due to pollen (J30.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
