What This Code Means
L24.A9 is the ICD-10-CM diagnosis code for irritant contact dermatitis due friction or contact with other specified body fluids. Skin irritation caused by friction or contact with body fluids other than saliva or incontinence products, such as sweat or wound drainage. L24.A9 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.A9 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.
Document the specific body fluid causing the irritation for clinical clarity.
