ICD Code M34.9

ICD code M34.9 is systemic sclerosis, unspecified, which refers to a connective tissue disease characterized by skin thickening and organ involvement, but without further specification of the type or severity.

1. Presence of skin thickening or hardening, particularly on the fingers, hands, or face

2. Raynaud’s phenomenon (color changes in fingers or toes in response to cold or stress)

3. Evidence of internal organ involvement (e.g., lungs, heart, kidneys, gastrointestinal tract) without a more specific subtype identified

4. Positive serologic markers associated with systemic sclerosis (e.g., ANA, anti-centromere, anti-Scl-70 antibodies)

5. Absence of features that would classify the condition under a more specific systemic sclerosis subtype

6. Chronic course with progressive fibrosis or sclerosis of skin and/or internal organs

7. No alternative diagnosis explaining the clinical presentation
