About coding senile hyperkeratosis
The ICD-10-CM code for senile hyperkeratosis is L57.0 (Actinic keratosis).
Within L57 (skin changes due to chronic exposure to nonionizing radiation), L57.0 is specifically for actinic keratosis. Related codes cover actinic reticuloid (L57.1), cutis rhomboidalis nuchae (L57.2), Poikiloderma of Civatte (L57.3), cutis laxa senilis (L57.4), 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.
