Other chronic hematogenous osteomyelitis, unsp humerus

This code signifies a persistent, blood-borne infection of the bone marrow and surrounding bone tissue in an unspecified humerus, not otherwise specified as acute or subacute. It indicates a long-standing inflammatory process within the humeral bone originating from a systemic infection.

Apply this code when documentation clearly states chronic hematogenous osteomyelitis affecting the humerus, without specifying laterality (left or right). This diagnosis is typically supported by imaging studies (X-ray, MRI, bone scan) showing chronic bone changes, positive bone cultures, and a history of systemic infection.

• Ensure documentation specifies "chronic" and "hematogenous" as the etiology.
• Avoid using this code if laterality (left or right humerus) is documented; more specific codes exist.
• Do not use for osteomyelitis resulting from direct trauma or contiguous spread; those have different code categories.
