About the M05–M14 Code Range
These conditions involve inflamed joints, including rheumatoid arthritis, juvenile arthritis, gout, and joint disease associated with other illnesses. Gout can cause repeated episodes of joint inflammation and urate deposits in and around joints.
M05 and M06 separate forms of rheumatoid arthritis by rheumatoid factor status and other named features. Within M05, subdivisions distinguish organ involvement from rheumatoid arthritis without that involvement. M07 identifies enteropathic joint disease, while M08 groups forms of arthritis that begin in childhood.
M10 groups gout by cause, and M1A does the same for chronic gout. The seventh character in M1A distinguishes chronic gout with or without a tophus. M11 groups other crystal joint diseases. M12 and M13 contain other named or unspecified joint conditions, while M14 identifies joint disease in other diseases.
