Disp fx of 3rd metatarsal bone, r ft, subs for fx w malunion

This code signifies a fracture of the third metatarsal bone in the right foot that has healed in an imperfect alignment, known as malunion. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously treated fracture.

This code is appropriate for documenting ongoing treatment, evaluation, or management of a right third metatarsal fracture that has developed malunion. This includes scenarios where a patient presents for assessment of pain, functional limitations, or consideration of corrective surgery due to the malunion.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing" for accurate code assignment.
• Verify laterality (right foot) is explicitly stated in the medical record.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
