Hey,
I think both conditions coded separately. Be'coz Note below 721.3 indicates w/o radiculopathy/myelopathy. i.e., 721.3 & 724.4. Take a lookup on the following info. if helps!
Spondylosis is a term referring to degenerative osteoarthritis of the joints between the centra of the spinal vertebrae and/or neural foraminae. In this condition the interfacetal joints are not involved.
If severe, it may cause pressure on nerve roots with subsequent sensory and/or motor disturbances, such as pain, paresthesia, or muscle weakness in the limbs.
When the space between two adjacent vertebrae narrows, compression of a nerve root emerging from the spinal cord may result in radiculopathy (sensory and motor disturbances, such as severe pain in the neck, shoulder, arm, back, and/or leg, accompanied by muscle weakness). Less commonly,
direct pressure on the spinal cord (typically in the cervical spine) may result in myelopathy, characterized by global weakness, gait dysfunction, loss of balance, and loss of bowel and/or bladder control. The patient may experience a phenomenon of shocks (paresthesia) in hands and legs because of nerve compression and lack of blood flow.
Radiculopathy is not a specific condition, but rather a description of a problem in which one or more nerves are affected and do not work properly (a neuropathy). The emphasis is on the nerve root (Radix = "root"). This can result in pain (radicular pain), weakness, numbness, or difficulty controlling specific muscles.
In a radiculopathy, the problem is at or near the root of the nerve, along the spine. However, the pain or other symptoms may manifest in an extremity through a process called referred pain. For example,an impingement in the lower back or lumbar-sacral spine can be manifested with symptoms in the foot.
Hope this helps!
