Other acute osteomyelitis, right radius and ulna

This code signifies an acute infection of the bone and bone marrow (osteomyelitis) affecting the right radius and ulna, but not specified as hematogenous (blood-borne). This condition typically involves inflammation, bone destruction, and potential pus formation within the bone structure of the forearm.

Apply this code when documentation clearly indicates acute osteomyelitis of the right radius and/or ulna, and the etiology is not specified as hematogenous. This would include cases resulting from direct inoculation (e.g., trauma, surgery) or contiguous spread from adjacent soft tissue infection. Supporting documentation should include physician notes detailing the diagnosis, location, and acute nature of the infection.

• Ensure the documentation specifies "acute" and not "chronic" osteomyelitis, as different codes apply.
• Verify laterality (right vs. left) and the specific bones involved (radius and ulna) are clearly stated.
• Distinguish from M86.2- (Other chronic osteomyelitis) and M86.3- (Osteomyelitis, hematogenous, acute) based on documentation.
