About L94.2

L94.2 is the ICD-10-CM diagnosis code for Calcinosis cutis. It belongs to category L94 (other localized connective tissue disorders), block L80-L99 (other disorders of the skin and subcutaneous tissue) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 709.3 (degenerative skin disorders) and 709.8 (other specified disorders of skin).
