About coding trunk furuncle

The ICD-10-CM code for trunk furuncle is L02.229 (Furuncle 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 L02.229.

Within L02.22, choose L02.229 (unspecified) only when documentation doesn't support a more specific option: abdominal wall (L02.221), back [any part, except buttock and flank] (L02.222), chest wall (L02.223), groin (L02.224), perineum (L02.225), umbilicus (L02.226) and flank (L02.227).

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.
