Pathological dislocation of left hand, NEC

This code signifies a non-traumatic displacement of the bones forming a joint in the left hand, specifically when the underlying cause is a disease process rather than an injury. This dislocation occurs due to weakened joint structures, often secondary to conditions like arthritis, infection, or neuromuscular disorders.

Apply this code when documentation clearly indicates a pathological (non-traumatic) dislocation affecting the left hand. This typically involves a physician's diagnosis of dislocation and a stated underlying disease process, such as rheumatoid arthritis or a chronic infection, as the cause. Imaging reports confirming dislocation and clinical notes detailing the absence of acute trauma support its use.

• Ensure the documentation specifies "pathological" and not traumatic dislocation.
• Always code the underlying disease causing the pathological dislocation first, if known.
• Verify laterality (left hand) is clearly documented to avoid coding errors.
