Displ transverse fx shaft of r ulna, 7thM

This code signifies a non-healing fracture of the shaft of the right ulna, specifically a transverse break that is no longer in proper alignment. It indicates that the initial injury was an open fracture, classified as either Type I or Type II, and the patient is now presenting for follow-up care due to the bone's failure to unite.

Use this code for a patient presenting for ongoing treatment of a previously sustained open transverse fracture of the right ulnar shaft that has not healed. This applies to situations where the fracture site remains unstable or shows no signs of bony fusion after an appropriate healing period, and the initial injury involved a break in the skin.

• Ensure documentation clearly states "nonunion" and specifies the right ulna.
• Verify the original injury was an open fracture, Type I or II, as this impacts the seventh character.
• Do not use for initial encounters or for malunion, which is a different complication.
