M20: Acquired deformities of fingers and toes

M20.6: Acquired deformity of toe(s), unspecified

Acquired deformity of toe(s), unspecified refers to changes in the shape, size, or alignment of one or several toes that occur after birth, not due to genetics. These irregularities can result from various causes, including wearing improper fitting shoes, suffering from certain diseases, like arthritis and diabetes, or because of an injury or trauma. Affected toes can become painful, stiff, or swollen, making it hard to walk. Often shapes of the affected toes can visibly change. For instance, they might bend unnaturally, curl under, or overlap neighboring toes. While the condition can affect any toe, the big and small toes are often most affected. Note, this term does not provide a specific diagnosis, and a healthcare professional may determine the exact deformity, which can include conditions like hammertoe or claw toe.
