Postimmunization arthropathy, right knee

This code signifies an inflammatory joint condition affecting the right knee that develops as a direct consequence of an immunization. It represents a reactive arthritis or arthropathy occurring after vaccine administration, specifically localized to the right knee joint.

Apply this code when documentation clearly states a diagnosis of arthropathy of the right knee directly attributed to a recent immunization. The medical record should specify the laterality (right knee) and the causal link to a vaccine.

• Ensure documentation explicitly links the arthropathy to an immunization and specifies the right knee.
• Do not use for general arthritis or arthralgia not directly caused by a vaccine.
• Consider sequencing this code after the primary reason for the encounter if the arthropathy is a secondary diagnosis.
