Chronic osteomyelitis with draining sinus, left shoulder

This code signifies a persistent, long-standing infection of the bone in the left shoulder, specifically characterized by the presence of a draining sinus. A draining sinus indicates a tract from the infected bone to the skin surface, allowing pus or fluid to escape.

Apply this code when documentation confirms chronic osteomyelitis affecting the left shoulder, and a draining sinus is explicitly noted. This typically follows an acute infection that has not resolved and has progressed to a chronic state with a visible or palpable sinus tract.

• Ensure documentation specifies "chronic" osteomyelitis and the presence of a "draining sinus."
• Verify the laterality is explicitly stated as "left shoulder."
• Do not confuse with acute osteomyelitis or chronic osteomyelitis without a draining sinus, as these have different codes.
