About L00

L00 is the ICD-10-CM diagnosis code for staphylococcal scalded skin syndrome. It belongs to 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.

Don't report L00 together with the conditions in its Excludes1 note: bullous impetigo (L01.03), pemphigus neonatorum (L01.03) and toxic epidermal necrolysis [Lyell] (L51.2).

Use an additional code to identify percentage of skin exfoliation (L49.-).

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 595 (Major Skin Disorders with MCC, relative weight 2.0239) and DRG 596 (Major Skin Disorders without MCC, relative weight 1.1071), 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 695.81 (Ritter's disease).
