Monoarthritis, not elsewhere classified, unspecified elbow

This code signifies inflammation of a single joint (monoarthritis) affecting the elbow, where the specific cause of the arthritis is not identified or classified under other more specific codes. It indicates an inflammatory process localized to one elbow joint without a definitive underlying etiology such as rheumatoid arthritis, gout, or infectious arthritis.

Apply this code when documentation clearly states "monoarthritis of the elbow" and no further specificity regarding the cause is provided. It is appropriate for cases where diagnostic workup for the underlying etiology is incomplete, inconclusive, or not performed, and the focus is on the localized elbow inflammation.

• Ensure documentation explicitly states "unspecified" or "not elsewhere classified" if the cause of monoarthritis is unknown.
• Avoid using this code if a more specific diagnosis (e.g., gouty arthritis, infectious arthritis) is documented for the elbow.
• Always review the medical record for laterality (right or left elbow) and use the appropriate specific code if available. This code is for unspecified laterality.
