2-part disp fx of surg nk of l humer, subs for fx w malunion

This code describes a situation where a patient has a fracture of the surgical neck of their left humerus that broke into two distinct pieces and is now healing incorrectly, resulting in a malunion. This specific code is used when the patient is seen for follow-up care related to this malunited fracture.

Use this code for a patient presenting for an office visit, imaging, or other treatment related to a previously diagnosed 2-part displaced surgical neck fracture of the left humerus that has healed in an unsatisfactory position. This applies to encounters where the focus is on managing the consequences of the malunion, such as pain, limited range of motion, or planning for corrective surgery.

• Ensure documentation clearly states "malunion" and specifies the left humerus and surgical neck.
• Verify the fracture was initially a "2-part displaced" fracture.
• This "P" seventh character indicates a subsequent encounter for a fracture with malunion, not the initial treatment or routine healing.
