Subacute osteomyelitis, right femur

This code identifies an inflammatory condition of the bone and bone marrow in the right femur that has progressed beyond the acute phase but has not yet become chronic. It signifies an infection that has persisted for weeks to a few months, often characterized by less severe symptoms than acute osteomyelitis.

Apply this code when documentation specifies osteomyelitis of the right femur with a subacute presentation. This typically involves a patient presenting with localized pain, swelling, and possibly fever, where symptoms have been present for an extended period (e.g., several weeks) but without the rapid onset and severe systemic signs of acute infection. Supporting documentation should clearly state "subacute" and specify the right femur.

• Ensure the documentation explicitly states "subacute" and not acute or chronic osteomyelitis.
• Verify the laterality is specified as "right" and the bone involved is the "femur."
• Consider sequencing this code after any underlying cause of the osteomyelitis, such as an open wound or fracture, if applicable.
