What This Code Means
L73.0 is the ICD-10-CM diagnosis code for acne keloid. A type of acne scar characterized by firm, raised, shiny bumps that form as a result of the body's healing response to acne lesions. L73.0 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering disorders of skin appendages (l60-l75).
L73.0 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.
Acne keloid is a specific type of acne scar; distinguish from hypertrophic scars and true keloids in the documentation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L73.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
