About coding Berlock dermatitis
The ICD-10-CM code for Berlock dermatitis is L56.2 (Photocontact dermatitis [berloque dermatitis]).
Within L56 (other acute skin changes due to ultraviolet radiation), L56.2 is specifically for Photocontact dermatitis [berloque dermatitis]. Related codes cover drug phototoxic response (L56.0), drug photoallergic response (L56.1), solar urticaria (L56.3), Polymorphous light eruption (L56.4), disseminated superficial actinic porokeratosis (DSAP) (L56.5), other specified acute skin changes due to ultraviolet radiation (L56.8) and acute skin change due to ultraviolet radiation, unspecified (L56.9).
Use an additional code to identify the source of the ultraviolet radiation (W89, X32).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
