Other hammer toe (acquired)

This code describes an acquired deformity of the toe where one or more of the toe joints are bent, causing the toe to resemble a hammer. It specifically refers to hammer toe conditions that are not congenital in origin and are not otherwise specified as a hallux rigidus or other specific toe deformity.

This code is appropriate for documenting an acquired hammer toe deformity affecting any toe other than the great toe, where the specific type of hammer toe (e.g., mallet toe, claw toe) is not explicitly documented or is considered "other." Documentation should clearly indicate an acquired, non-congenital hammer toe.

• Differentiate from congenital hammer toe (755.66) and hallux rigidus (735.0).
• Ensure documentation specifies "acquired" if not inherently clear from the clinical context.
• Consider laterality if documented, though ICD-9-CM does not offer laterality for this specific code.
