ICD-10 code for cutis degeneration

The ICD-10-CM code for cutis degeneration is L98.8 (Other specified disorders of the skin and subcutaneous tissue). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L98.8.

Within L98, choose L98.8 (Other specified disorders of the skin and subcutaneous tissue) only when documentation doesn't support a more specific option: pyogenic granuloma (L98.0), Factitial dermatitis (L98.1), febrile neutrophilic dermatosis [Sweet] (L98.2), eosinophilic cellulitis [Wells] (L98.3), Non-pressure chronic ulcer of skin, not elsewhere classified (L98.4), Mucinosis of the skin (L98.5), other infiltrative disorders of the skin and subcutaneous tissue (L98.6), excessive and redundant skin and subcutaneous tissue (L98.7) and 2 more.

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.
