Chronic osteomyelitis with draining sinus, right humerus

This code signifies a persistent infection of the right humerus bone, characterized by the presence of a draining sinus tract. The sinus indicates a chronic inflammatory process where pus or fluid continuously drains from the bone to the skin surface. This condition is typically long-standing and resistant to conventional antibiotic therapy.

Apply this code when documentation clearly states chronic osteomyelitis affecting the right humerus, specifically noting the presence of a draining sinus. This often occurs following trauma, surgery, or hematogenous spread of infection. Supporting documentation should include physician notes detailing the chronicity, location, and the observation of a draining sinus.

• Ensure documentation specifies "chronic" osteomyelitis; acute osteomyelitis is coded differently.
• Verify the laterality (right) and specific bone (humerus) are clearly documented.
• Do not confuse with osteomyelitis without a draining sinus, which would require a different subcategory.
