Direct infct of r knee in infec/parastc dis classd elswhr

This code signifies an inflammatory condition of the right knee joint directly caused by an underlying infectious or parasitic disease. It indicates that the infection in the knee is a manifestation or complication of a systemic infectious process, rather than a primary, localized infection.

Use this code when documentation clearly states a direct infection of the right knee secondary to a specified infectious or parasitic disease. Examples include Lyme arthritis affecting the knee, or a fungal infection spreading to the joint. Documentation should identify both the specific infectious agent and the right knee involvement.

• Always sequence the underlying infectious or parasitic disease code first, as this code is a "manifestation" code.
• Ensure the documentation specifies "right knee" and not another joint or unspecified knee.
• Distinguish from codes for primary septic arthritis of the knee (e.g., M00.-) where the infection is not classified as a direct manifestation of another disease.
