Cervical disc disorder at C4-C5 level with myelopathy

This code signifies a degenerative or structural issue affecting the intervertebral disc between the fourth and fifth cervical vertebrae, which is causing compression of the spinal cord. Myelopathy indicates neurological dysfunction due to this spinal cord compression, potentially leading to motor weakness, sensory changes, or gait disturbance.

Apply this code when documentation clearly states a cervical disc disorder at the C4-C5 level and explicitly mentions the presence of myelopathy. This is typically supported by imaging (MRI, CT) showing disc pathology at C4-C5 and neurological examination findings consistent with spinal cord compression.

• Ensure the documentation specifies "myelopathy" and not just radiculopathy, as these are distinct conditions.
• Verify the exact cervical level (C4-C5) is documented; do not assume based on symptoms.
• This code requires a definitive diagnosis of both the disc disorder and the resulting myelopathy.
