Postimmunization arthropathy, left wrist

This code signifies an inflammatory joint condition affecting the left wrist that develops as an adverse reaction following an immunization. It represents a sterile arthritis, not an infection, directly attributable to a vaccine.

Apply this code when documentation clearly links new-onset or exacerbated arthropathy of the left wrist to a recent vaccination. The physician's notes should specify the laterality and the causal relationship to an immunization.

• Always sequence this code after the primary diagnosis for the specific immunization adverse effect (e.g., T88.1- for other complications of vaccination).
• Ensure documentation specifies "arthropathy" and not just generalized pain or swelling, and clearly indicates the left wrist.
• Do not use for infectious arthritis following immunization; those would be coded separately with an infection code.
