Displ spiral fx shaft of ulna, unsp arm, 7thM

This code signifies a spiral fracture of the ulna shaft that is out of alignment and has failed to heal (nonunion). The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and the patient is receiving follow-up care after initial treatment. This specific code applies when the affected arm is not documented.

Use this code for a patient presenting for ongoing management of a previously treated open spiral ulna shaft fracture (Type I or II) that has not united. This includes situations like cast changes, wound care, or evaluation for further surgical intervention due to nonunion. It is appropriate when the laterality of the arm is not specified in the medical record.

• Always confirm the fracture type (spiral), displacement, and the presence of nonunion.
• Verify that the encounter is subsequent care for an open fracture type I or II.
• Only use this code when the documentation does not specify whether the fracture is on the left or right arm.
