About coding Atrophoderma
The ICD-10-CM code for Atrophoderma is L90.9 (Atrophic disorder of skin, unspecified). The official index lists 12 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on L90.9.
Within L90, choose L90.9 (Atrophic disorder of skin, unspecified) only when documentation doesn't support a more specific option: lichen sclerosus et atrophicus (L90.0), Anetoderma of Schweninger-Buzzi (L90.1), Anetoderma of Jadassohn-Pellizzari (L90.2), Atrophoderma of Pasini and Pierini (L90.3), acrodermatitis chronica atrophicans (L90.4), scar conditions and fibrosis of skin (L90.5), Striae atrophicae (L90.6) and other atrophic disorders of skin (L90.8).
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.
