Polyarthritis, unspecified

This code signifies inflammation affecting five or more joints, without further specification of the underlying cause or specific type of polyarthritis. It indicates a generalized inflammatory process involving multiple joints.

Use this code when the medical record clearly documents polyarthritis but lacks specific details regarding its etiology (e.g., rheumatoid, psoriatic, crystal-induced) or the specific joints involved. This is appropriate when the provider has not yet determined a more precise diagnosis or when documentation is insufficient for a more specific code.

• Avoid using this code if a more specific type of polyarthritis (e.g., rheumatoid arthritis, psoriatic arthritis) is documented.
• Query the provider for further specificity if possible to achieve a more precise diagnosis code.
• This code is often used as a temporary or provisional diagnosis pending further workup and definitive diagnosis.
