In neurosurgical practice, patients with cranial defects are often seen. Cranial defects are a relatively common disorder that can be caused by cranial trauma or left over from craniotomy due to the patient’s own craniosynostosis. Cranial bone is very important to the human body and plays an important role in protecting and supporting the brain and craniofacial organs, and once cranial defect occurs, it will produce many hazards to the body, making the brain and craniofacial soft tissues face safety threats, destabilizing the intracranial environment and triggering a series of cranial defect syndrome, in addition to the aesthetic appearance of the skull and the patient’s mental psychology will also have adverse effects, so cranial Therefore, patients with cranial defects should undergo cranial bone repair in time. In recent years, a new type of special polymer material, polyether ether ketone PEEK, has been introduced into the clinic, which has excellent performance. It has become a new trend of cranial bone repair material. Whether Peek cranial bone can be reimbursed depends on what you want to report, whether you want to take the medical insurance reimbursement, or the new agricultural cooperative reimbursement, or commercial insurance claims reimbursement, or any other reimbursement categories, depending on the local reimbursement policy or the specific commercial terms and conditions. We use Beijing’s medical insurance policy to say that PEEK materials are valuable medical materials, and a percentage of their cost is included in the reimbursement.
