Infective myositis, unspecified hand

This code signifies inflammation of the muscles in an unspecified hand due to an infection. It indicates a localized infectious process affecting the muscular tissue, without further specification of the causative organism.

Use this code when documentation clearly states "infective myositis" affecting a hand, but the specific hand (left or right) is not identified. This diagnosis is typically supported by clinical findings such as pain, swelling, tenderness, and warmth in the hand muscles, often accompanied by systemic signs of infection.

• Ensure the documentation explicitly states "infective myositis" and specifies involvement of a hand.
• If the specific hand (left or right) is documented, use the more precise laterality code (M60.041 or M60.042).
• Always code the underlying infectious agent (e.g., B95-B97 for bacterial infections) as an additional diagnosis, if known and documented.
