Oth chronic hematogenous osteomyelit, unsp tibia and fibula

This code signifies a persistent, long-term bone infection of the tibia and/or fibula that originated from a bloodstream infection, where the specific type of chronic osteomyelitis is not further specified. It indicates an ongoing inflammatory process within the bone marrow and cortex, often leading to bone destruction and new bone formation.

Use this code for patients diagnosed with chronic osteomyelitis of the lower leg bones (tibia and fibula) where the infection is known to be hematogenous in origin, but the physician documentation does not specify a more precise type of chronic hematogenous osteomyelitis. Documentation should clearly state "chronic hematogenous osteomyelitis" affecting the tibia and/or fibula without further detail.

• Ensure documentation specifies "chronic" and "hematogenous" to differentiate from acute or other forms of osteomyelitis.
• Avoid using this code if a more specific type of chronic hematogenous osteomyelitis (e.g., with draining sinus, with sequestrum) is documented; instead, select a more precise subcategory.
• Always review for laterality (right, left, bilateral) if specified in the documentation; this code is for "unspecified" laterality.
