Other chronic hematogenous osteomyelitis, unsp shoulder

This code signifies a persistent, long-term infection of the bone and bone marrow in the shoulder, originating from a blood-borne source. It indicates that the specific type of chronic hematogenous osteomyelitis is not further specified, nor is the laterality of the affected shoulder.

Apply this code when documentation confirms chronic osteomyelitis of the shoulder, with a clear indication of hematogenous origin, but without further specification of the type or laterality. This is appropriate when the physician notes "chronic hematogenous osteomyelitis of the shoulder, NOS" or similar.

• Ensure documentation explicitly states "chronic" and "hematogenous" to support this code.
• Avoid using this code if the documentation specifies the type of chronic osteomyelitis (e.g., multifocal, with draining sinus) or the laterality (right/left shoulder).
• Always query the provider for laterality if not documented, as more specific codes exist (M86.511, M86.512).
