Infective myositis, unspecified lower leg

This code signifies inflammation of the muscle tissue in the lower leg caused by an infectious agent, where the specific lower leg (right or left) is not documented. It represents a localized muscle infection without further specification of the causative organism.

Apply this code when documentation indicates infective myositis affecting the lower leg, but the laterality (right or left) is not specified. This is appropriate when the physician's notes state "infective myositis of the lower leg" without further detail.

• Ensure documentation explicitly states "unspecified lower leg" or lacks laterality for the lower leg.
• If the specific infectious agent is known, a secondary code for the infection should be assigned.
• Avoid using this code if laterality (right or left lower leg) is clearly documented; instead, use the more specific M60.061 or M60.062.
