What This Code Means
L24.5 is the ICD-10-CM diagnosis code for irritant contact dermatitis due to other chemical products. Skin irritation caused by contact with various chemical products not covered by other specific categories, such as pesticides or industrial chemicals. L24.5 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering dermatitis and eczema (l20-l30).
L24.5 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code for chemical irritants that don't fit into the more specific L24 subcategories.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L24.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
