ICD-10 code for lichen ruber kaposi's

The ICD-10-CM code for lichen ruber kaposi's is L44.0 (Pityriasis rubra pilaris). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L44.0.

Within L44 (other papulosquamous disorders), L44.0 is specifically for pityriasis rubra pilaris. Related codes cover lichen nitidus (L44.1), lichen striatus (L44.2), lichen ruber moniliformis (L44.3), infantile papular acrodermatitis [Gianotti-Crosti] (L44.4), other specified papulosquamous disorders (L44.8) and papulosquamous disorder, unspecified (L44.9).

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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), 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.
