Oth chronic hematogenous osteomyelitis, left radius and ulna

This code signifies a persistent, long-term infection of the bone marrow and surrounding bone tissue in the left radius and ulna, caused by bacteria or other microorganisms spread through the bloodstream. It indicates an ongoing inflammatory process within these specific forearm bones, distinct from acute or subacute forms of osteomyelitis.

Use this code when documentation clearly states chronic hematogenous osteomyelitis affecting the left radius and ulna. This diagnosis is typically supported by imaging studies (X-rays, MRI, bone scan) showing chronic changes, positive bone cultures, and a prolonged clinical course of infection. It applies to cases where the infection is not directly due to trauma or surgery at the site.

• Ensure documentation specifies "chronic" and "hematogenous" to differentiate from acute or contiguous osteomyelitis.
• Verify the laterality (left) and specific bones (radius and ulna) are clearly documented.
• Do not use this code for osteomyelitis resulting from a direct infection (e.g., post-surgical, open fracture); those cases would fall under different categories.
