Nondisp spiral fx shaft of ulna, l arm, 7thK

This code signifies a non-displaced spiral fracture occurring in the shaft of the left ulna. The "K" seventh character indicates that this is a subsequent encounter for a closed fracture that has not healed properly, meaning there is a nonunion of the bone fragments.

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed, non-displaced spiral fracture of the left ulnar shaft that has failed to unite. This would include scenarios such as monitoring the nonunion, discussing further treatment options, or managing complications related to the nonunion, provided the fracture remains closed.

• Ensure the documentation clearly specifies "nonunion" for a closed fracture in the left ulnar shaft.
• Verify that the encounter is a subsequent one, not the initial treatment for the fracture.
• Confirm the fracture is non-displaced and spiral in nature, affecting the ulnar shaft.
