Sclerodactyly

Sclerodactyly is a localized thickening and tightening of the skin of the fingers or toes, often making them appear shiny and waxy. This condition is a hallmark feature of systemic sclerosis (scleroderma) but can also occur in other connective tissue diseases. It typically leads to limited range of motion and can cause significant functional impairment.

This code is used when documentation specifically identifies sclerodactyly as a distinct clinical finding. It is appropriate for cases where the skin changes are confined to the digits, regardless of the underlying etiology. Supporting documentation should clearly describe the characteristic skin thickening and tightening of the fingers or toes.

• Always code the underlying systemic condition, such as systemic sclerosis (M34.-), first if known.
• Differentiate from other localized sclerosing skin conditions that do not specifically affect the digits.
• Ensure documentation specifies involvement of fingers or toes to support this diagnosis.
