Other kyphosis, cervical region

This code signifies an abnormal, excessive anterior curvature of the cervical spine, not specified as postural or due to secondary conditions like tuberculosis or trauma. It represents a structural deformity of the neck region, often leading to a "humpback" appearance in that area.

Apply this code when documentation explicitly states "other kyphosis" or "unspecified kyphosis" affecting the cervical spine. This diagnosis is typically supported by imaging studies (X-rays, MRI) demonstrating the abnormal curvature and a physician's clinical assessment.

• Ensure the documentation specifies "cervical region" for accurate code assignment; avoid using for other spinal regions.
• Distinguish from postural kyphosis (M40.0-) or kyphosis due to secondary causes (M40.1-), which have more specific codes.
• Always review the physician's notes for laterality or specific etiology if available, as more precise codes may exist.
