Direct infct of unsp hand in infec/parastc dis classd elswhr

This code signifies an inflammatory joint condition of the hand resulting directly from an infection originating from another infectious or parasitic disease. The specific infectious agent is not inherent to the joint itself but has spread to cause arthritis in an unspecified hand.

Use this code when documentation clearly indicates infectious arthritis of the hand secondary to a systemic infectious or parasitic disease, and the specific hand (left or right) is not documented. This code requires a primary diagnosis code for the underlying infectious or parasitic disease.

• Always sequence the underlying infectious or parasitic disease code first, followed by this code.
• Avoid using this code if the specific hand (left or right) is documented; instead, use the more specific M01.X41 or M01.X42.
• Ensure documentation specifies "direct infection" or "infectious arthritis" of the hand, not just general inflammation.
