Fx unsp carpal bone, left wrist, subs for fx w routn heal

This code signifies a fracture of any of the carpal bones in the left wrist, where the specific carpal bone involved is not documented. The patient is in a subsequent phase of treatment, and the fracture is progressing with expected, routine healing.

Use this code when a patient presents for follow-up care of a left wrist carpal bone fracture, and the initial injury was not specified to a particular carpal bone (e.g., "left carpal fracture"). This code is appropriate when the physician's documentation indicates that the healing process is proceeding normally without complications.

• Ensure documentation specifies "left wrist" and "unspecified carpal bone" for accurate assignment.
• Confirm the encounter is for follow-up care and not the initial treatment of the fracture.
• Verify that the physician's notes indicate "routine healing" to differentiate from delayed healing or nonunion.
