Ossification of posterior longitudinal ligament in cervical region

This code signifies the pathological hardening and calcification of the ligament located along the back of the vertebral bodies in the neck. This ossification can lead to spinal canal narrowing, potentially compressing the spinal cord or nerve roots. It is a progressive condition that can cause myelopathy or radiculopathy.

Assign this code when documentation explicitly states ossification of the posterior longitudinal ligament (OPLL) specifically affecting the cervical spine. Supporting documentation will often include imaging reports (e.g., X-ray, CT, MRI) confirming the presence and location of the ossification. Use this code for patients presenting with symptoms attributable to cervical OPLL.

• Ensure the documentation specifies "cervical region" for accurate code assignment.
• Do not confuse with ossification in other spinal regions; specific codes exist for thoracic or lumbar involvement.
• Code any associated neurological deficits (e.g., myelopathy, radiculopathy) separately as secondary diagnoses.
