L03.032Cellulitis of left toe

L03.032 is the ICD-10-CM diagnosis code for cellulitis of left toe. It belongs to category L03 (cellulitis and acute lymphangitis), 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 L03.03 (cellulitis of toe), L03.032 is specifically for cellulitis of left toe. Related codes cover right toe (L03.031) and unspecified toe (L03.039).

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 573 (Skin Graft for Skin Ulcer or Cellulitis with MCC, relative weight 6.3575), DRG 574 (Skin Graft for Skin Ulcer or Cellulitis with CC, relative weight 3.5674), DRG 575 (Skin Graft for Skin Ulcer or Cellulitis without CC/MCC, relative weight 1.8797), 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 hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 681.10 (cellulitis and abscess of toe, unspecified) and 681.11 (Onychia and paronychia of toe).
