About coding chronic radiodermatitis
The ICD-10-CM code for chronic radiodermatitis is L58.1 (Chronic radiodermatitis).
Within L58 (radiodermatitis), L58.1 is specifically for chronic radiodermatitis. Related codes cover acute radiodermatitis (L58.0) and unspecified (L58.9).
Use an additional code to identify the source of the radiation (W88, W90).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
