About coding skin xerosis
The ICD-10-CM code for skin xerosis is L85.3 (Xerosis cutis).
Within L85 (other epidermal thickening), L85.3 is specifically for xerosis cutis. Related codes cover acquired ichthyosis (L85.0), acquired keratosis [keratoderma] palmaris et plantaris (L85.1), keratosis punctata (palmaris et plantaris) (L85.2), other specified epidermal thickening (L85.8) and epidermal thickening, unspecified (L85.9).
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.
