Displ commnt fx shaft of rad, unsp arm, 7thK

This code describes a complex fracture of the radius bone in the forearm, specifically a comminuted fracture (broken into multiple pieces) that is displaced (bones are out of alignment). The "unspecified arm" indicates that the laterality (left or right) is not documented. The "subsequent encounter for closed fracture with nonunion" specifies that this is a follow-up visit for a fracture that was initially closed (skin intact) but has failed to heal properly.

This code is appropriate for documenting a patient's visit for ongoing management of a comminuted, displaced radial shaft fracture that has not united. This would include scenarios where the patient is undergoing further evaluation, treatment planning (e.g., considering surgical intervention for nonunion), or monitoring of a previously treated fracture that has failed to heal.

• Ensure documentation clearly states "nonunion" for a closed fracture.
• Verify that the encounter is subsequent, not initial, for this specific fracture.
• If laterality (left or right arm) is documented, a more specific code should be used.
