Other acute osteomyelitis, right humerus

This code signifies an acute inflammatory process of the bone and bone marrow, specifically affecting the right humerus, that is not due to a bacterial infection like staphylococcus or salmonella. It indicates a rapid onset and progression of the infection, often characterized by pain, swelling, and fever. The "other" classification suggests the causative organism is not specified or is a less common pathogen.

Use this code when documentation clearly states acute osteomyelitis of the right humerus, and the infectious agent is either unknown, not specified as staphylococcal or salmonella, or identified as another organism. This code is appropriate for initial encounters for acute osteomyelitis. Supporting documentation should include physician notes detailing the diagnosis, location, and acuity of the osteomyelitis.

• Ensure the documentation specifies "acute" to differentiate from chronic osteomyelitis.
• Verify the laterality (right) and bone (humerus) are explicitly stated.
• If the specific bacterial cause (e.g., staphylococcal, salmonella) is identified, a more specific code from the M86.1- subcategory should be used.
