Non-radiographic axial spondyloarthritis of cervicothor rgn

This code identifies a chronic inflammatory arthropathy primarily affecting the spine and sacroiliac joints, specifically when radiographic evidence of sacroiliitis is absent. It denotes the involvement of the cervicothoracic region, indicating inflammation and pain in the neck and upper back. This condition is part of the broader spectrum of spondyloarthritis.

Apply this code for patients diagnosed with non-radiographic axial spondyloarthritis where clinical assessment, imaging (other than plain radiographs, such as MRI showing active inflammation), and laboratory findings support the diagnosis, and the primary affected area is the cervicothoracic spine. Documentation should explicitly state "non-radiographic axial spondyloarthritis" and specify cervicothoracic involvement.

• Ensure documentation clearly distinguishes between radiographic and non-radiographic forms of axial spondyloarthritis.
• Confirm the specific spinal region (cervicothoracic) is documented to support this granular code.
• Consider co-reporting codes for associated manifestations, such as peripheral arthritis, enthesitis, or uveitis, if present.
