This code is part of the broader category of spondylosis, which encompasses degenerative changes in the spine, particularly affecting the intervertebral discs and vertebrae. Below is a detailed clinical description and relevant information regarding this specific code.

Clinical Description

Definition of Spondylosis

Spondylosis is a term used to describe age-related wear and tear of the spinal discs. It is commonly associated with osteoarthritis of the spine and can lead to the formation of bone spurs, disc degeneration, and changes in the spinal structure. The condition can occur in various regions of the spine, including the cervical, thoracic, and lumbar areas.

Specifics of M47.21

The code M47.21 specifically denotes spondylosis that occurs in the occipito-atlanto-axial region, which includes the upper cervical spine, particularly the junction between the skull (occiput) and the first two cervical vertebrae (atlas and axis). This area is crucial for head movement and supports the skull.

Radiculopathy

Radiculopathy refers to the symptoms that occur when a nerve root in the spine is compressed or irritated. In the context of M47.21, radiculopathy may manifest as pain, numbness, or weakness that radiates from the neck into the shoulders, arms, or hands. This is often due to the degenerative changes associated with spondylosis, which can lead to nerve root compression.

Clinical Presentation

Symptoms

Patients with M47.21 may experience:
- Neck Pain: Often described as a dull ache or sharp pain.
- Radicular Symptoms: Pain, tingling, or numbness that radiates down the arms.
