Unsp fx second MC bone, left hand, subs for fx w routn heal

This code signifies an unspecified fracture of the second metacarpal bone in the left hand that is currently in a routine healing phase. The "unspecified" nature indicates that the specific type of fracture (e.g., transverse, oblique, comminuted) was not documented.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a left second metacarpal fracture that is progressing as expected. It should be used when the initial injury has already been coded and the patient is not experiencing complications or delayed healing.

• Ensure documentation specifies "left hand" and "second metacarpal" for accurate coding.
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or complications.
• Verify that the fracture type is truly unspecified; if a specific type is documented, a more precise code should be selected.
