Disp fx of shaft of unsp MC bone, subs for fx w delay heal

This code signifies a broken metacarpal bone in the hand, where the bone fragments are not properly aligned. The fracture is located in the main body (shaft) of one of the metacarpals, but the specific bone is not identified. This particular code is used when the patient is seen for follow-up care and the fracture is healing slower than expected.

Apply this code for a patient presenting for a follow-up visit for a previously diagnosed displaced metacarpal shaft fracture that is exhibiting delayed union. This would include scenarios where imaging shows incomplete healing beyond the typical timeframe, or the physician documents delayed healing. It is appropriate when the specific metacarpal (e.g., second, third) is not documented.

• Always ensure documentation specifies "delayed healing" for subsequent encounters.
• If the specific metacarpal is known, a more precise code should be used (e.g., S62.321G for the second metacarpal).
• This code requires a 7th character extender; "G" indicates subsequent encounter for fracture with delayed healing.
