Nondisp fx of coracoid pro, l shldr, subs for fx w nonunion

This code describes a fracture of the coracoid process, a small hook-like projection on the scapula, specifically on the patient's left side. The fracture is "nondisplaced," meaning the bone fragments are still in their normal anatomical alignment. The key aspect of this code is that it represents a subsequent encounter where the fracture has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up visits or hospitalizations when a patient with a previously diagnosed nondisplaced left coracoid fracture is found to have a nonunion. This would include scenarios where the physician is evaluating the nonunion, planning further treatment for the nonunion (e.g., surgery, bone stimulation), or managing complications related to the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "left shoulder" for the coracoid process fracture.
• Verify that the encounter is for a "subsequent encounter" and that "nonunion" is explicitly documented as the reason for the ongoing care.
• Do not use this code for initial encounters, malunion, or routine follow-up of a healing fracture without nonunion.
