What This Code Means
L49.0 is the ICD-10-CM diagnosis code for exfoliation due to erythematous condition involving less than 10 percent of body surface. Skin peeling or shedding due to a red, inflamed skin condition affecting less than 10 percent of the body surface. L49.0 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering urticaria and erythema (l49-l54).
L49.0 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 percentage of body surface area affected to ensure accurate code selection.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L49.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
