About coding acquired dermatolysis
The ICD-10-CM code for acquired dermatolysis is L57.4 (Cutis laxa senilis).
Within L57 (skin changes due to chronic exposure to nonionizing radiation), L57.4 is specifically for cutis laxa senilis. Related codes cover actinic keratosis (L57.0), actinic reticuloid (L57.1), cutis rhomboidalis nuchae (L57.2), Poikiloderma of Civatte (L57.3), actinic granuloma (L57.5), other skin changes due to chronic exposure to nonionizing radiation (L57.8) and unspecified (L57.9).
Use an additional code to identify the source of the ultraviolet radiation (W89), or other nonionizing radiation (W90).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
