About coding trunk carbuncle
The ICD-10-CM code for trunk carbuncle is L02.239 (Carbuncle of trunk, unspecified). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L02.239.
Within L02.23, choose L02.239 (unspecified) only when documentation doesn't support a more specific option: abdominal wall (L02.231), back [any part, except buttock and flank] (L02.232), chest wall (L02.233), groin (L02.234), perineum (L02.235), umbilicus (L02.236) and flank (L02.237).
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.
