Oth fx upr end unsp ulna, 7thQ

This code signifies a follow-up encounter for an open fracture of the upper part of the ulna (the bone on the pinky-finger side of the forearm) that was initially classified as an open fracture type I or II. At this subsequent encounter, the fracture has healed in an imperfect alignment, known as a malunion. The specific location of the fracture within the upper ulna is not specified.

This code is appropriate when a patient presents for ongoing care of an open ulna fracture (initially Gustilo-Anderson type I or II) that has healed with a noticeable deformity or angulation. This would typically be used after the initial treatment phase, during rehabilitation or follow-up appointments where the malunion is being addressed or monitored.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" in relation to an open ulna fracture.
• Verify the original fracture was documented as an open fracture type I or II.
• Do not use for nonunion or routine follow-up without malunion.
