Other hammer toe(s) (acquired), unspecified foot

This code signifies an acquired deformity of the toe(s) where the middle joint is bent downwards, resembling a hammer. This condition can affect any toe other than the great toe and is not congenital. The "unspecified foot" indicates that the laterality (left or right) is not documented.

Apply this code when documentation clearly states "hammer toe" and does not specify if it's on the left or right foot, or if it affects multiple toes without laterality. This code is appropriate for acquired hammer toe deformities, not those present at birth.

• Avoid using this code if the documentation specifies laterality (e.g., "left hammer toe"); instead, use a more specific code.
• Distinguish from "mallet toe" (distal joint bent) or "claw toe" (both proximal and distal joints bent).
• Ensure the documentation confirms the condition is acquired, not congenital.
