About coding nitidus lichen
The ICD-10-CM code for nitidus lichen is L44.1 (Lichen nitidus).
Within L44 (other papulosquamous disorders), L44.1 is specifically for lichen nitidus. Related codes cover pityriasis rubra pilaris (L44.0), 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.
