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

This code signifies an acquired deformity of the right foot where one or more toes are bent at the middle joint, resembling a hammer. This condition is typically characterized by the toe's proximal interphalangeal joint being flexed, while the distal interphalangeal joint may be extended or flexed. It is a common foot deformity that can cause pain, calluses, and difficulty with footwear.

Apply this code when documentation clearly indicates an acquired hammer toe deformity affecting the right foot. This includes conditions such as rigid or flexible hammer toes that are not congenital. Supporting documentation should specify the laterality (right foot) and confirm the acquired nature of the deformity.

• Ensure documentation specifies "acquired" to differentiate from congenital deformities.
• Verify laterality; use M20.42 for the left foot and M20.40 for unspecified laterality.
• Look for associated conditions like corns or calluses (L84, L85.1) and bunions (M20.1-) which may also need to be coded.
