Unspecified fracture of upper end of right ulna, sequela

This code indicates a long-term complication or late effect stemming from an unspecified fracture of the proximal (upper) end of the right ulna. It signifies that the initial fracture has healed, but the patient is now experiencing residual issues directly attributable to that past injury.

This code is appropriate when documenting a patient presenting with a current condition (e.g., chronic pain, limited range of motion, nonunion, malunion, or deformity) that is a direct consequence of a previously sustained, unspecified fracture of the upper right ulna. It should be used after the acute phase of the original fracture has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.521 for chronic pain in right elbow).
• Ensure documentation clearly links the current condition to the prior unspecified right ulnar fracture.
• Verify that the initial fracture was indeed of the "unspecified" type and located at the "upper end" of the right ulna.
