3-part fx surg neck of unsp humer, subs for fx w delay heal

This code signifies a complex fracture of the humerus, specifically involving three distinct breaks in the surgical neck region, where the shaft meets the head of the bone. The "unspecified" laterality indicates that the medical record does not specify whether the left or right arm is affected. The "subsequent encounter" and "delayed healing" components indicate that the patient is receiving ongoing care for this fracture, and the bone is not mending at the expected rate.

Use this code for follow-up visits or ongoing treatment for a patient diagnosed with a three-part surgical neck humerus fracture where the specific side (left or right) is not documented, and the fracture is exhibiting delayed union. This applies when the physician is actively managing the delayed healing process, such as recommending further interventions or monitoring progress.

• Ensure documentation clearly states "delayed healing" for this specific fracture.
• Verify that the laterality (left/right) is truly unspecified in the medical record before using this code.
• Confirm that this is a subsequent encounter, not the initial treatment for the fracture.
