Rheumatoid arthritis, unspecified

This code represents a chronic autoimmune inflammatory disorder primarily affecting the joints, leading to pain, swelling, stiffness, and potential joint damage. It signifies a diagnosis of rheumatoid arthritis where the specific type or associated complications are not documented.

Use this code when the medical record clearly states a diagnosis of rheumatoid arthritis but lacks further specificity regarding seropositivity, organ involvement, or other distinguishing features. This is appropriate when the provider has not documented a more precise form of the disease.

• Avoid using this code if the documentation specifies seropositive or seronegative rheumatoid arthritis; use the more specific codes in the M05 series.
• Always query the provider for greater specificity if possible, as more detailed codes offer better data for quality measures and risk adjustment.
• Do not use this code if the documentation indicates juvenile rheumatoid arthritis; refer to the M08 series for those conditions.
