L53.2Erythema marginatum

L53.2 is the ICD-10-CM diagnosis code for erythema marginatum. It belongs to category L53 (other erythematous conditions), block L49-L54 (urticaria and erythema) 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 L53 (other erythematous conditions), L53.2 is specifically for erythema marginatum. Related codes cover toxic erythema (L53.0), erythema annulare centrifugum (L53.1), other chronic figurate erythema (L53.3), other specified erythematous conditions (L53.8) and erythematous condition, unspecified (L53.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 595 (Major Skin Disorders with MCC, relative weight 2.0239), DRG 596 (Major Skin Disorders without MCC, relative weight 1.1071), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), 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 695.0 (toxic erythema).
