Systemic sclerosis, unspecified

This code represents systemic sclerosis (scleroderma) when the specific type or extent of the disease is not documented. It indicates a chronic, progressive autoimmune connective tissue disorder characterized by fibrosis of the skin and internal organs, but without further specification.

This code is appropriate when the medical record clearly states a diagnosis of "systemic sclerosis" or "scleroderma" but lacks details to classify it as limited cutaneous, diffuse cutaneous, or another specific form. It should be used when the provider has not specified the clinical subtype.

• Avoid using this code if documentation allows for a more specific systemic sclerosis code (e.g., M34.0, M34.1, M34.2).
• Query the provider for clarification on the type of systemic sclerosis if possible to achieve higher specificity.
• This code is a "not otherwise specified" (NOS) code and should be used as a last resort when no further information is available.
