Postimmunization arthropathy, unspecified site

This code signifies joint pain or inflammation that develops as an adverse reaction following an immunization, where the specific joint affected is not documented. It represents an inflammatory response in the joints triggered by a vaccine, without specifying the anatomical location of the arthropathy.

Apply this code when a patient presents with arthropathy clearly linked to a recent vaccination, and the medical record does not specify which joint(s) are involved. Documentation should explicitly state "postimmunization arthropathy" or similar, and confirm the absence of a specific site.

• Always attempt to code to the highest level of specificity; if a specific joint is documented (e.g., knee, shoulder), use a more precise code from the M02.2- subcategory.
• Ensure the documentation clearly links the arthropathy to a recent immunization; otherwise, consider other arthropathy codes.
• Sequence this code after the primary reason for the encounter if the arthropathy is a secondary diagnosis.
