Oth fracture of shaft of radius, unsp arm, init for clos fx

This code signifies a break in the main part (shaft) of the radius bone in the forearm, where the specific type of fracture is not documented. It applies when the injury is to an unspecified arm and the skin over the fracture remains intact. This is the first time the patient is receiving active treatment for this particular injury.

This code is appropriate for initial encounters when documentation confirms a closed fracture of the radial shaft, but the physician does not specify the exact fracture pattern (e.g., transverse, oblique, spiral). It is also used when the medical record does not indicate which arm (left or right) was affected.

• Ensure documentation explicitly states "unspecified arm" or lacks laterality for the radius fracture.
• Verify the fracture is explicitly documented as "closed" and this is the initial treatment encounter.
• Avoid this code if a more specific fracture type (e.g., transverse, oblique) or laterality (left/right) is documented; look for more precise codes within the S52.3 category.
