Oth chronic hematogenous osteomyelit, right tibia and fibula

This code signifies a persistent, long-term infection of the bone and bone marrow in the right lower leg (tibia and fibula) that originated from a blood-borne source. This condition is characterized by ongoing inflammation and bone destruction due to the presence of microorganisms.

Apply this code when documentation clearly indicates chronic osteomyelitis of the right tibia and fibula, and the etiology is specified as hematogenous (spread via the bloodstream). This typically follows an initial acute infection that was not fully resolved.

• Ensure documentation specifies "chronic" and "hematogenous" to differentiate from acute or other forms of osteomyelitis.
• Laterality (right) and specific bones (tibia and fibula) must be clearly documented.
• Do not use for osteomyelitis due to direct inoculation (e.g., trauma, surgery) or contiguous spread.
