Other acute osteomyelitis, unspecified hand

This code signifies an acute inflammatory process of the bone and bone marrow within an unspecified hand, caused by an infection. It represents a sudden onset of bone infection that has not been further specified as to the causative organism or specific bone involved within the hand.

Use this code when documentation confirms acute osteomyelitis affecting any bone of the hand, but the specific bone (e.g., carpal, metacarpal, phalanx) is not identified. This code is appropriate when the medical record clearly states "acute osteomyelitis of the hand" without further anatomical detail.

• Ensure the documentation specifies "acute" osteomyelitis; chronic forms use different codes.
• Avoid this code if the specific bone of the hand is documented (e.g., acute osteomyelitis of the scaphoid bone), as more specific codes exist.
• Always look for documentation of the infectious agent (e.g., Staphylococcus aureus) to assign an additional code for the infection.
