Other streptococcal polyarthritis

This code signifies an inflammatory joint condition affecting multiple joints, specifically caused by a streptococcal infection, but not meeting the criteria for acute rheumatic fever. It represents a reactive arthritis following a streptococcal infection, often presenting with migratory polyarthralgia or polyarthritis.

Use this code when documentation clearly indicates polyarthritis attributed to a recent streptococcal infection, and the physician has ruled out acute rheumatic fever. Supporting documentation should include evidence of streptococcal infection (e.g., positive strep test, elevated ASO titer) and clinical findings of multiple joint inflammation.

• Ensure documentation specifies "other" streptococcal polyarthritis to differentiate from rheumatic fever.
• Sequence this code as the primary diagnosis when the polyarthritis is the reason for the encounter.
• Do not use this code if the polyarthritis is a manifestation of acute rheumatic fever; instead, refer to codes in category I00.
