Nondisp fx of 2nd metatarsal bone, unsp ft, 7thP

This code describes a situation where a patient has a second metatarsal fracture that was initially nondisplaced but is now healing incorrectly, resulting in a malunion. This indicates a complication in the bone's healing process where the fragments have joined in a deformed position.

This code is appropriate for follow-up encounters where a previously diagnosed nondisplaced second metatarsal fracture is being evaluated, and clinical or radiological findings confirm a malunion. It would be used when the patient is receiving ongoing care for the improperly healed fracture.

• Ensure documentation clearly states "malunion" and specifies the second metatarsal.
• Verify the fracture was initially nondisplaced; otherwise, a different malunion code may be more appropriate.
• This code is for subsequent encounters, not the initial treatment of the fracture.
