The ICD-10-CM code for scalp cellulitis is L03.811 (Cellulitis of head [any part, except face]).
Within L03.81 (cellulitis of other sites), L03.811 is specifically for cellulitis of head [any part, except face]. Related codes cover other sites (L03.818).
The conditions in its Excludes2 note aren't part of L03.811, but may be coded alongside it if the patient has both: cellulitis of face (L03.211).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
