Chronic osteomyelitis with draining sinus, right hand

This code identifies a persistent, long-term infection of the bone in the right hand that has progressed to form a draining tract or fistula to the skin surface. This indicates an ongoing inflammatory process with pus discharge.

Apply this code when documentation confirms a diagnosis of chronic osteomyelitis affecting the right hand, specifically noting the presence of a draining sinus. Supporting clinical notes should detail the chronicity of the infection and the physical manifestation of the draining tract.

• Ensure documentation clearly specifies "chronic" osteomyelitis and the presence of a "draining sinus."
• Laterality (right hand) is crucial for accurate code assignment; avoid using unspecified laterality codes.
• Distinguish from acute osteomyelitis or chronic osteomyelitis without a draining sinus, as these have different codes.
