Other chronic hematogenous osteomyelitis, multiple sites

This code signifies a persistent, long-term bone infection that has spread through the bloodstream, affecting multiple distinct anatomical locations. It represents a non-acute inflammatory process within the bone and bone marrow, caused by microorganisms disseminated via the circulatory system.

Apply this code when documentation clearly indicates chronic osteomyelitis affecting more than one bone, with a confirmed or strongly suspected hematogenous origin. This is appropriate for cases where the infection is not acute and is not specified as a particular type of chronic osteomyelitis (e.g., Brodie's abscess, Garré's osteomyelitis).

• Ensure documentation specifies "chronic" and "multiple sites" to differentiate from acute or single-site infections.
• Do not use if the specific type of chronic hematogenous osteomyelitis is identified; instead, code to the more specific diagnosis.
• Always sequence this code after the underlying infectious agent (e.g., B95-B97) if known and documented.
