About coding Urhidrosis
The ICD-10-CM code for Urhidrosis is L74.8 (Other eccrine sweat disorders).
Within L74, choose L74.8 (Other eccrine sweat disorders) only when documentation doesn't support a more specific option: miliaria rubra (L74.0), miliaria crystallina (L74.1), miliaria profunda (L74.2), miliaria, unspecified (L74.3), Anhidrosis (L74.4), focal hyperhidrosis (L74.5) and eccrine sweat disorder, unspecified (L74.9).
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.
