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

This code signifies a fracture of the humerus shaft that is displaced and located transversely, affecting an unspecified arm. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone has failed to heal properly after the initial injury.

Use this code for patients presenting for ongoing treatment of a previously diagnosed displaced transverse humeral shaft fracture where the arm is not specified (e.g., documentation states "humerus fracture" without laterality). This code is specifically for cases where the fracture has not united and requires further intervention or management.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the encounter type is "subsequent" and not initial or sequela.
• Confirm the fracture is of the humeral shaft and is displaced and transverse.
