Acute hematogenous osteomyelitis, unsp radius and ulna

This code signifies an acute bone infection originating from the bloodstream, affecting the radius and/or ulna. It indicates a sudden onset of inflammation and destruction of bone tissue in the forearm, without further specification of the exact bone or laterality.

Apply this code when documentation confirms acute osteomyelitis of the radius and/or ulna, and the etiology is clearly stated as hematogenous. This is appropriate when the specific bone (radius vs. ulna) or the affected side (left, right, bilateral) is not documented.

• Ensure the documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Avoid using this code if the specific radius or ulna, or laterality, is known; instead, use a more specific code from the M86.03 series.
• Always review for any associated systemic infections or underlying conditions that may require additional coding.
