Postimmunization arthropathy, right ankle and foot

This code signifies inflammation and pain in the right ankle and foot joints that develops as a direct reaction to a recent immunization. It represents an adverse musculoskeletal effect following vaccine administration, specifically affecting the specified anatomical site.

Apply this code when documentation clearly links arthropathy of the right ankle and foot to a recent vaccination. The patient's medical record should indicate the onset of joint symptoms in the right ankle and foot occurring after immunization, with no other apparent cause.

• Ensure the documentation specifies "right ankle and foot" and clearly links the arthropathy to an immunization.
• Always sequence this code after the appropriate T code for the adverse effect of the vaccine (e.g., T88.1 for other complications of vaccination).
• Do not use this code for arthropathy due to infectious agents or other non-immunization related causes.
