2025 ICD-10-CM code M99.41

Narrowing of the cervical spinal canal due to connective tissue.

Use an external cause code (e.g., injury, trauma) if applicable to identify the underlying cause of the stenosis.

Medical necessity is established by demonstrating the presence of signs and symptoms of nerve compression or spinal cord dysfunction related to the stenosis, such as pain, numbness, weakness, or gait disturbances.

Diagnosis is based on patient history, physical exam, and imaging (X-rays, MRI). Treatment may include pain medication, physical therapy, chiropractic care, and massage therapy.

In simple words: The spinal canal in your neck is narrowed because of the tissue around it.

Connective tissue stenosis of the neural canal of the cervical region refers to a narrowing of the spinal canal in the neck due to the surrounding connective tissue.

Example 1: A patient presents with neck pain and limited range of motion. Imaging reveals narrowing of the spinal canal due to thickened ligaments, confirming a diagnosis of connective tissue stenosis., Following a neck injury, a patient develops symptoms of nerve compression. Diagnostic tests show connective tissue stenosis contributing to the compression., An older adult experiences gradual onset of neck pain and stiffness. MRI reveals age-related thickening of the connective tissue surrounding the spinal canal, leading to a diagnosis of connective tissue stenosis.

Patient history, physical examination findings, and imaging results (X-rays, MRI) confirming the stenosis and its location in the cervical region.
