Claw toe (acquired)

This code describes an acquired deformity of the toe characterized by hyperextension of the metatarsophalangeal joint, flexion of the proximal interphalangeal joint, and flexion of the distal interphalangeal joint, resulting in a claw-like appearance. This condition typically affects the lesser toes and can cause pain, calluses, and difficulty with footwear.

Use this code when documentation clearly indicates an acquired claw toe deformity. This includes conditions resulting from neuromuscular disorders, inflammatory arthritis, or ill-fitting shoes, as opposed to congenital deformities. Supporting documentation should specify the toe affected and laterality if known.

• Differentiate from hammer toe (flexion of PIP joint only) and mallet toe (flexion of DIP joint only).
• Ensure documentation specifies "acquired" to avoid confusion with congenital deformities.
• Consider additional codes for underlying causes or associated conditions, such as arthritis or nerve damage.
