Bennett's fracture, unsp hand, subs for fx w routn heal

This code signifies a Bennett's fracture, which is an intra-articular fracture of the base of the first metacarpal bone, extending into the carpometacarpal joint. This specific code indicates that the fracture is in an unspecified hand and the patient is in the routine healing phase following initial treatment.

Apply this code for follow-up encounters where a patient with a previously diagnosed Bennett's fracture of an unspecified hand is receiving ongoing care, and the fracture is progressing through a normal healing process. This includes visits for cast changes, physical therapy assessments, or routine follow-up appointments during the typical recovery period.

• Ensure documentation clearly states "unspecified hand" if laterality is not specified.
• Confirm the encounter is for a "subsequent encounter" and the healing is "routine" (not delayed or complicated).
• Do not use this code for initial treatment or for nonunion/malunion complications.
