Acute hematogenous osteomyelitis, left ankle and foot

This code signifies an acute bone infection originating from the bloodstream, specifically affecting the left ankle and/or foot. It indicates a sudden onset inflammatory process of the bone and bone marrow in this anatomical region due to bacterial or fungal dissemination.

Apply this code when documentation confirms a diagnosis of acute osteomyelitis in the left ankle or foot, with a clear indication that the infection is hematogenous in origin. Supporting documentation includes positive blood cultures, imaging (e.g., MRI, X-ray) showing acute bone changes, and clinical signs of infection such as fever, localized pain, and swelling.

• Ensure documentation explicitly states "acute" and "hematogenous" to support this specific code.
• Verify the laterality (left) and anatomical site (ankle and foot) are clearly documented.
• Do not use this code for chronic osteomyelitis or osteomyelitis resulting from direct inoculation or contiguous spread.
