Nondisp spiral fracture of shaft of ulna, unsp arm, sequela

This code signifies a past injury involving a spiral fracture of the ulna's shaft that has since healed, but the patient is experiencing a residual condition or complication directly related to that previous fracture. The fracture was nondisplaced, meaning the bone fragments remained in their anatomical alignment at the time of the initial injury. The specific arm affected is not documented.

This code is appropriate when a patient presents with a long-term consequence, such as chronic pain, limited range of motion, nonunion, malunion, or nerve damage, that is directly attributable to a previously sustained nondisplaced spiral fracture of the ulnar shaft. It should be used after the initial healing phase of the fracture is complete and the patient is being treated for the lasting effects.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the previous ulnar fracture.
• Verify that the original fracture was indeed nondisplaced and spiral in nature, affecting the shaft of the ulna.
