ICD-10 Code L94.2 – Calcinosis cutis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L94.2 – Calcinosis cutis
What it is
Calcinosis cutis means calcium deposits form in the skin or subcutaneous tissue. The code identifies the condition itself, not the underlying cause of the calcium buildup.
Clinical signs
Typical findings include firm, whitish or yellowish skin nodules, plaques, or chalky drainage. Clinical features vary; refer to documentation.
When to use this code
Use L94.2 when the provider documents calcinosis cutis as the diagnosis. It applies when calcium deposits are described in the skin, even if the note also mentions an associated disorder. Check documentation if the record only describes calcification elsewhere.
Do not use for
Do not use this code for calcification limited to blood vessels, organs, or other tissues without skin involvement. If the chart does not clearly state calcinosis cutis, check documentation.
Coding tip
Confirm the documentation names skin involvement and code any underlying condition separately when supported.
