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

This code signifies a long-term complication or residual effect stemming from a previously sustained spiral fracture of the shaft of the left ulna, where the bone fragments remained in their anatomical alignment. It indicates that the initial injury has healed, but the patient is now experiencing a persistent issue directly attributable to that fracture.

Apply this code when documenting a patient presenting with a current condition (e.g., chronic pain, limited range of motion, nonunion, malunion) that is a direct consequence of a healed, nondisplaced spiral fracture of the left ulnar shaft. This code is appropriate for follow-up encounters addressing these sequelae, not for the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.522 for chronic left elbow pain).
• Ensure documentation clearly links the current condition to the historical left ulnar shaft fracture.
• Verify the fracture was indeed nondisplaced and spiral in nature, affecting the shaft of the ulna, and located on the left arm.
