About coding leukonychia
The ICD-10-CM code for leukonychia is L60.8 (Other nail disorders). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L60.8.
Within L60, choose L60.8 (Other nail disorders) only when documentation doesn't support a more specific option: Ingrowing nail (L60.0), Onycholysis (L60.1), Onychogryphosis (L60.2), nail dystrophy (L60.3), Beau's lines (L60.4), yellow nail syndrome (L60.5) and nail disorder, unspecified (L60.9).
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.
