Displaced spiral fx shaft of ulna, left arm, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained spiral fracture of the shaft of the left ulna, where the bone fragments were not in their normal anatomical alignment. It indicates that the initial injury has healed, but the patient is now experiencing residual issues directly attributable to that specific fracture.

This code is appropriate when documenting conditions such as chronic pain, malunion, nonunion, limited range of motion, or other persistent functional impairments in the left arm that are directly linked to a past displaced spiral ulna shaft fracture. It should be used after the acute phase of the fracture has passed and treatment for the initial injury is complete.

• Always sequence this code after the code for the specific sequela (e.g., M84.222A for malunion of ulna).
• Ensure documentation clearly links the current condition to the previous displaced spiral fracture of the left ulna shaft.
• Do not use this code for initial encounters or active treatment of the acute fracture.
