Acute hematogenous osteomyelitis, unsp tibia and fibula

This code signifies an acute bone infection originating from the bloodstream, affecting an unspecified bone within the lower leg (tibia or fibula). It indicates a sudden onset inflammatory process of the bone and bone marrow caused by bacteria or other microorganisms disseminated through the blood.

Apply this code when documentation specifies acute hematogenous osteomyelitis of the tibia or fibula, but does not specify which of the two bones is affected. This is appropriate for initial encounters where the specific bone (tibia vs. fibula) has not yet been definitively identified or documented.

• Always strive for greater specificity regarding the affected bone (e.g., tibia, fibula) if documented.
• Distinguish between acute and chronic osteomyelitis; this code is exclusively for acute presentations.
• Consider an additional code for the infectious agent if known and documented.
