Infective myositis, right hand

This code signifies an inflammatory condition of the muscles in the right hand caused by an infection. It involves the direct invasion of muscle tissue by microorganisms, leading to pain, swelling, and impaired function. This is distinct from myositis caused by autoimmune or other non-infectious etiologies.

Apply this code when documentation clearly indicates an infectious process affecting the muscles of the patient's right hand. This typically includes findings such as positive cultures from muscle biopsy or aspirate, purulent discharge, or clinical signs of infection (e.g., fever, erythema, warmth) localized to the right hand musculature.

• Always confirm the laterality (right hand) is explicitly documented.
• Do not use this code for non-infectious myositis; refer to codes in the M60.8- or M60.9- series for other specified or unspecified myositis.
• Code the underlying infectious agent (e.g., B95-B97 for bacterial, viral, or other infectious agents) as an additional diagnosis when known.
