Greenstick fx shaft of rad, unsp arm, subs for fx w malunion

This code describes a specific type of incomplete fracture, a greenstick fracture, affecting the main body of the radius bone in an unidentifiable arm. It indicates that the fracture has previously been treated but has healed in an unsatisfactory alignment, known as a malunion.

This code is appropriate for follow-up encounters where a patient is being evaluated or treated for a greenstick fracture of the radial shaft that has healed incorrectly. This could include assessment for corrective procedures, physical therapy for functional deficits due to malunion, or ongoing monitoring. It signifies that the initial treatment has concluded, but the bone has not aligned properly during the healing process.

• Ensure documentation clearly specifies "greenstick fracture" and "malunion" for the radial shaft.
• Verify that the encounter is for follow-up care related to the malunion, not initial treatment or routine healing.
• Confirm that the arm laterality is truly unspecified in the medical record before using this code.
