Nondisp fx of base of fifth metacarpal bone, left hand, 7thP

This code signifies a previously sustained fracture at the base of the fifth metacarpal in the left hand that is now healing improperly, resulting in a malunion. The fracture itself was initially nondisplaced, meaning the bone fragments remained in their anatomical alignment at the time of injury.

This code is appropriate when a patient presents for follow-up care of a left fifth metacarpal base fracture that has healed in an unsatisfactory position. It indicates that the fracture has united, but with an unacceptable angular or rotational deformity. This code is used during the period of active treatment for the malunion or for complications arising from it.

• Ensure documentation clearly specifies "malunion" and the specific bone (fifth metacarpal) and side (left hand).
• Verify that the initial fracture was indeed nondisplaced; if displaced, a different code would be appropriate.
• This "P" seventh character indicates a subsequent encounter for a fracture with malunion, not a new injury or initial treatment.
