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

This code signifies an inflammatory joint condition (arthritis) affecting the left hand, directly caused by an underlying infectious or parasitic disease. The infection itself is not primarily in the joint but has spread to or is manifesting as arthritis within the left hand.

Apply this code when documentation clearly indicates infectious arthritis of the left hand, and the specific infectious or parasitic etiology is known and coded elsewhere. This code is appropriate when the infection is systemic or originates from another site and secondarily affects the left hand joint.

• Always sequence the underlying infectious or parasitic disease code first, followed by this code.
• Ensure documentation specifies "left hand" and confirms the infectious etiology of the arthritis.
• Do not use for non-infectious inflammatory arthropathies or localized infections of the hand not involving the joint.
