Greenstick fracture of shaft of radius, unsp arm, init

This code signifies a greenstick fracture affecting the main body (shaft) of the radius bone, where the bone is bent and partially broken, but not completely separated. It indicates that the specific arm involved (left or right) is not documented, and this is the initial treatment for the injury, which has not broken through the skin.

Apply this code for pediatric patients presenting with a partial fracture of the radial shaft, typically from a fall or minor trauma, where the periosteum remains intact on one side. This is appropriate when the medical record does not specify laterality and the fracture is being treated for the first time without an open wound.

• Ensure documentation clearly states "greenstick" and "shaft of radius" for accurate code assignment.
• Only use this code when the arm laterality is truly unspecified in the medical record.
• Verify that this is the initial encounter for treatment of the closed fracture; subsequent encounters or open fractures require different codes.
