Unsp fx upper end unsp radius, subs for clos fx w malunion

This code signifies a fracture of the upper portion of the radius bone, where the specific location of the fracture is not documented. It indicates that the patient is in a subsequent phase of care for this closed fracture, and the bone has healed in an anatomically incorrect or misaligned position.

This code is appropriate for follow-up encounters when a patient presents with a previously diagnosed, unspecified closed fracture of the proximal radius that has healed with malunion. This would include situations where imaging confirms the malunion and the patient is receiving ongoing management, such as physical therapy or evaluation for corrective surgery.

• Ensure documentation clearly states "malunion" and that the encounter is for follow-up care of a closed fracture.
• Verify that the fracture location is indeed "unspecified" within the upper end of the radius; otherwise, a more specific code should be used.
• Do not use this code for initial encounters or for open fractures.
