About coding cutis osteosis
The ICD-10-CM code for cutis osteosis is L94.2 (Calcinosis cutis).
Within L94 (other localized connective tissue disorders), L94.2 is specifically for Calcinosis cutis. Related codes cover localized scleroderma [morphea] (L94.0), linear scleroderma (L94.1), Sclerodactyly (L94.3), Gottron's papules (L94.4), Poikiloderma vasculare atrophicans (L94.5), Ainhum (L94.6), other specified localized connective tissue disorders (L94.8) and localized connective tissue disorder, unspecified (L94.9).
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.
