Nondisp fx of hook pro of hamate bone, unsp wrs, 7thK

This code signifies a fracture of the hook of the hamate bone in an unspecified wrist that has not healed properly (nonunion) and is being addressed in a subsequent encounter. The fracture itself is not displaced, meaning the bone fragments are still in their normal anatomical alignment.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed, nondisplaced hook of hamate fracture in an unspecified wrist that has failed to unite. This includes encounters for ongoing treatment, evaluation of nonunion, or planning for further intervention related to the nonunion.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for a nondisplaced hook of hamate fracture.
• Verify the wrist laterality is indeed unspecified; otherwise, a more specific code should be used.
• Do not use this code for initial encounters or for fractures that have healed or are healing normally.
