Displaced oblique fracture of shaft of right ulna, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained oblique fracture in the shaft of the right ulna, where the bone fragments were not perfectly aligned. It indicates that the patient is still experiencing issues directly related to this past injury, even after the initial healing phase.

Apply this code when documenting a patient presenting with ongoing symptoms, functional limitations, or other sequelae directly attributable to a past displaced oblique fracture of the right ulnar shaft. This includes conditions like malunion, nonunion, chronic pain, or nerve damage that developed as a consequence of the original fracture.

• Always sequence this code after the code describing the specific sequela (e.g., M84.2x for nonunion).
• Ensure documentation clearly links the current condition to the previous right ulnar shaft fracture.
• Verify laterality (right ulna) and fracture type (oblique, shaft, displaced) are explicitly stated in the medical record.
