The ICD-10-CM code for scalp furuncle is L02.821 (Furuncle of head [any part, except face]).
Within L02.82 (furuncle of other sites), L02.821 is specifically for furuncle of head [any part, except face]. Related codes cover other sites (L02.828).
Use an additional code to identify organism (B95-B96).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
