About coding Ritter's disease
The ICD-10-CM code for Ritter's disease is L00 (Staphylococcal scalded skin syndrome).
Don't report L00 together with the conditions in its Excludes1 note: bullous impetigo (L01.03), pemphigus neonatorum (L01.03) and toxic epidermal necrolysis [Lyell] (L51.2).
Use an additional code to identify percentage of skin exfoliation (L49.-).
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 L00)
