Displ oblique fx shaft of unsp ulna, 7thP

This code describes a situation where a patient has a displaced fracture of the ulna shaft, specifically an oblique type, that is currently healing incorrectly (malunion). The fracture was previously treated, and this encounter is for follow-up care related to the malunion.

Use this code for a patient presenting for ongoing management of a previously treated, closed oblique ulna shaft fracture that has healed in an unsatisfactory position. This applies to follow-up visits, cast changes, or evaluations for further intervention (e.g., surgical correction) due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the "ulna shaft" and "oblique" fracture type.
• Verify the encounter is "subsequent" and the fracture was "closed" initially.
• Do not use for initial treatment or for nonunion, which is a separate condition.
