Other specified rheumatoid arthritis, vertebrae

This code signifies a form of rheumatoid arthritis that affects the vertebral column, but does not fit into more specific categories of rheumatoid arthritis. It indicates an inflammatory autoimmune condition primarily impacting the joints of the spine, leading to pain, stiffness, and potential structural damage.

Apply this code when documentation specifies rheumatoid arthritis with involvement of the vertebrae, and the specific type of rheumatoid arthritis is not otherwise classified (e.g., without rheumatoid factor, with rheumatoid factor, juvenile). This code is appropriate when the physician's notes clearly indicate spinal manifestations of rheumatoid arthritis that are not further detailed.

• Ensure documentation explicitly states "rheumatoid arthritis" and "vertebrae" or "spinal involvement."
• Do not use if a more specific M05 or M06 subcategory for rheumatoid arthritis with spinal involvement is available and documented.
• Consider sequencing this code after a more general rheumatoid arthritis code if the vertebral involvement is a manifestation of a primary, more broadly defined rheumatoid arthritis.
