Nondisp transverse fx shaft of humer, unsp arm, 7thK

This code describes a situation where a patient has a transverse fracture of the humerus shaft that is not displaced, and the specific arm (left or right) is not documented. The fracture has not healed as expected, and the patient is receiving ongoing treatment for this nonunion.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced transverse humerus shaft fracture that has failed to unite. This applies when the documentation does not specify which arm is affected and the focus of the encounter is the nonunion.

• Ensure documentation clearly states "nondisplaced," "transverse," and "shaft of humerus."
• Verify that the encounter is for ongoing treatment of the nonunion, indicating a subsequent encounter.
• Only use this code when the laterality (left or right arm) is explicitly unspecified in the medical record.
