Nondisp transverse fx shaft of l ulna, 7thK

This code describes a situation where a patient has a transverse fracture of the shaft of their left ulna that is not displaced. Importantly, this is a subsequent encounter for the fracture, and there is evidence that the bone is failing to heal properly (nonunion) despite the fracture being treated without surgery (closed fracture).

Use this code when a patient presents for follow-up care of a previously diagnosed nondisplaced transverse left ulnar shaft fracture, and imaging or clinical assessment confirms that the fracture has not united. This applies to situations where the initial treatment was non-surgical, such as casting or splinting.

• Ensure documentation clearly states "nondisplaced" and "transverse" for the left ulnar shaft.
• Verify that the encounter is for follow-up care and that nonunion is explicitly documented.
• Confirm the fracture was initially managed as a closed fracture.
