About L08.0

L08.0 is the ICD-10-CM diagnosis code for pyoderma. It belongs to category L08 (other local infections of skin and subcutaneous tissue), 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 L08 (other local infections of skin and subcutaneous tissue), L08.0 is specifically for pyoderma. Related codes cover Erythrasma (L08.1), other specified local infections of the skin and subcutaneous tissue (L08.8) and local infection of the skin and subcutaneous tissue, unspecified (L08.9).

Don't report L08.0 together with the conditions in its Excludes1 note: pyoderma gangrenosum (L88) and pyoderma vegetans (L08.81).

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 hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 686.00 (pyoderma, unspecified).
