Displacement of int fix of left humerus, subs

This code signifies that an internal fixation device, such as a plate, screw, or rod, that was surgically implanted in the patient's left humerus has shifted from its intended position. This displacement can compromise the stability of the fracture repair and may lead to pain, loss of function, or non-union. It indicates a complication requiring further medical attention.

Apply this code when documentation explicitly states a displacement of an internal fixation device in the left humerus during a follow-up visit or subsequent treatment for the complication. This is appropriate for encounters where the patient is receiving active treatment for the displaced device, such as evaluation for revision surgery or conservative management.

• Ensure the documentation specifies "displacement" and not merely a loosening or breakage, which have different codes.
• Verify the laterality is explicitly "left humerus" to avoid incorrect coding.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase of the complication.
