ICD-10 code for marginatum erythema

The ICD-10-CM code for marginatum erythema is L53.2 (Erythema marginatum). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L53.2.

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.
