Oth fx first MC bone, unsp hand, subs for fx w delay heal

This code signifies a fracture of the first metacarpal bone (thumb) that is not further specified as a Bennett's or Rolando's fracture, located in an unspecified hand. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing.

Apply this code for follow-up encounters where a patient presents with a previously diagnosed, non-specific first metacarpal fracture, and the physician documents that the healing process is slower than expected. This is appropriate when the specific hand (left or right) is not documented.

• Ensure documentation clearly states "delayed healing" for the subsequent encounter.
• Verify that the fracture is of the first metacarpal and not another carpal or metacarpal bone.
• If the specific hand is known, a more precise code (e.g., S62.291G, S62.292G) should be used instead.
