Nondisp transverse fracture of shaft of left ulna, sequela

This code describes a long-term complication or late effect stemming from a transverse fracture in the shaft of the left ulna that was not displaced at the time of the initial injury. It indicates that the patient is experiencing ongoing issues directly related to this past fracture, even after the acute phase of healing has passed.

This code is appropriate for documenting conditions such as chronic pain, stiffness, nonunion, malunion, or other persistent functional limitations in the left forearm that are directly attributable to a previously sustained, nondisplaced transverse ulnar shaft fracture. It should be used when the patient is presenting for treatment of these residual effects, not for the initial acute injury.

• Always assign an additional code to specify the nature of the sequela (e.g., M25.522 for chronic pain, M84.222A for delayed union).
• Ensure documentation clearly links the current condition to the historical nondisplaced transverse fracture of the left ulnar shaft.
• Do not use this code for the initial encounter or subsequent encounters for active treatment of the acute fracture itself.
