About coding Factitial dermatosis
The ICD-10-CM code for Factitial dermatosis is L98.1 (Factitial dermatitis).
Within L98 (other disorders of skin and subcutaneous tissue, not elsewhere classified), L98.1 is specifically for Factitial dermatitis. Related codes cover pyogenic granuloma (L98.0), febrile neutrophilic dermatosis [Sweet] (L98.2), eosinophilic cellulitis [Wells] (L98.3), Non-pressure chronic ulcer of skin, not elsewhere classified (L98.4), Mucinosis of the skin (L98.5), other infiltrative disorders of the skin and subcutaneous tissue (L98.6), excessive and redundant skin and subcutaneous tissue (L98.7), other specified disorders of the skin and subcutaneous tissue (L98.8) and 2 more.
Don't report L98.1 together with the conditions in its Excludes1 note: Excoriation (skin-picking) disorder (F42.4).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for L98.1)
- Excoriation (skin-picking) disorder (F42.4)
