About L02.232
L02.232 is the ICD-10-CM diagnosis code for carbuncle of back [any part, except buttock and flank]. It belongs to category L02 (cutaneous abscess, furuncle and carbuncle), block L00-L08 (infections of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within L02.23 (carbuncle of trunk), L02.232 is specifically for carbuncle of back [any part, except buttock and flank]. Related codes cover abdominal wall (L02.231), chest wall (L02.233), groin (L02.234), perineum (L02.235), umbilicus (L02.236), flank (L02.237) and unspecified (L02.239).
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 602 (Cellulitis with MCC, relative weight 1.4273) and DRG 603 (Cellulitis without MCC, relative weight 0.8635), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2027 (title revised).
Before ICD-10, this condition was coded in ICD-9-CM as 680.2 (carbuncle and furuncle of trunk).
