Infective myositis, classified under ICD-10 code M60.039, refers to an inflammation of the muscle tissue in the forearm due to an infectious process. Diagnosing this condition involves a combination of clinical evaluation, laboratory tests, and imaging studies. Below are the key criteria and steps typically used in the diagnosis of infective myositis:

Clinical Evaluation

1. Patient History:
   - A thorough medical history is essential, including any recent infections, trauma, or exposure to infectious agents.
   - Symptoms such as muscle pain, swelling, weakness, and fever should be documented.

2. Physical Examination:
   - The physician will assess the affected forearm for signs of inflammation, such as tenderness, swelling, and warmth.
   - Muscle strength testing may reveal weakness in the affected area.

Laboratory Tests
