Infective myositis, unspecified forearm

This diagnosis code signifies an inflammatory condition of the muscle tissue in the forearm caused by an infectious agent. The specific type of infection (e.g., bacterial, viral, fungal) is not identified, nor is the laterality of the forearm specified. It indicates a generalized infection affecting the muscle fibers.

Use this code when documentation clearly states "infective myositis" affecting the forearm, but the causative organism is unknown or not specified. This code is appropriate when the medical record does not provide laterality (right or left forearm) for the myositis. Supporting documentation would include physician notes detailing forearm pain, swelling, and signs of infection, with a diagnosis of myositis without further specificity.

• Avoid using this code if the specific infectious agent is known; instead, code to a more specific myositis subcategory (e.g., M60.00-M60.08).
• Do not use if laterality (right or left forearm) is documented; select the appropriate M60.031 or M60.032 code.
• Always review the entire medical record for more specific details regarding the infection and affected site to ensure the most precise code is selected.
