Chronic osteomyelitis with draining sinus, right shoulder

This code signifies a persistent bone infection in the right shoulder that has formed a tract or channel to the skin surface, allowing for the discharge of pus or fluid. This indicates a long-standing inflammatory process within the bone, often following trauma or surgery, with a visible external manifestation.

Apply this code when documentation clearly states chronic osteomyelitis affecting the right shoulder, specifically noting the presence of a draining sinus. This is typically seen in patients with recurrent infections or those who have not responded to initial treatment for acute osteomyelitis.

• Ensure documentation specifies "chronic" and "draining sinus" in relation to the osteomyelitis.
• Laterality (right shoulder) is crucial for accurate code assignment.
• Do not use for acute osteomyelitis or chronic osteomyelitis without a draining sinus.
