Oth fx shaft of rad, unsp arm, subs for clos fx w delay heal

This code signifies a fracture of the main part of the radius bone, not otherwise specified, in an unspecified arm. The "subsequent encounter" indicates that the patient is receiving follow-up care for a previously diagnosed fracture, and "delayed healing" specifies that the bone is not mending at the expected rate.

This code is appropriate for encounters where a patient is being managed for a persistent, non-union, or slow-to-heal closed diaphyseal radius fracture. This would include follow-up appointments for cast changes, imaging to assess healing progress, or discussions regarding further intervention due to delayed consolidation.

• Ensure documentation clearly states "delayed healing" for a closed radius shaft fracture.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• If the arm (left or right) is specified in the documentation, a more specific code should be used.
