Displ transverse fx shaft of unsp ulna, 7thP

This code signifies a previously sustained fracture of the ulna shaft, specifically a transverse break that is now healing in a misaligned position (malunion). The fracture's exact location on the ulna is not specified, and the bone was not exposed to the environment during the initial injury.

Apply this code when documenting follow-up care for a patient whose ulnar shaft fracture, initially closed and transverse, has healed or is healing with a noticeable deformity or angulation. This is used for subsequent encounters after the initial treatment, indicating ongoing management of the malunion.

• Ensure documentation clearly states "malunion" and that the fracture was initially "closed" and "transverse."
• Verify that this is a "subsequent encounter" and not the initial treatment or a sequela.
• The "unspecified ulna" component means the documentation does not specify laterality (left or right).
