ICD-10-PCS Code For Occipital Bone: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0NU7 includes procedures performed to supplement biological or synthetic material in the occipital bone of the head and facial bones. These ICD-10-PCS codes are used for inpatient documentation when material is placed in or on the occipital bone to reinforce or augment its function. Accurate coding within the ICD-10-PCS 0NU7 group is essential for proper inpatient reimbursement, as it captures the specific supplement procedure performed and supports clinical documentation accuracy.

Occipital Bone Supplement Procedure Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the occipital bone and surrounding head and facial bones. These operations target the Head and Facial Bones body system and typically supplement bone structure to restore function, provide support, or stabilize defects. Accurate coding of these procedures matters for inpatient reimbursement because it documents the specific supplement operation and the anatomical site, which affects case mix and payment.

When to Use

Use a code from this group when biological or synthetic material is put in or on the occipital bone to reinforce, augment, or support bone structure during an inpatient procedure. Select these codes when the primary intent of the procedure is supplementation of the occipital bone rather than removal, replacement, or repair.

Typical Clinical Scenarios

A patient presents after a high-energy blunt trauma to the posterior skull with depressed occipital bone fractures and associated dural exposure; neurosurgery admits the patient for open debridement and structural augmentation of the occipital defect to protect neural elements and restore skull contour. An open approach is used to place biologic or synthetic material to supplement the fractured occipital bone during the same inpatient operation. Typical codes: 0NU707Z, 0NU70JZ
An adult with a large congenital occipital skull defect undergoing a planned inpatient reconstruction where bone graft and/or a synthetic cranioplasty implant are placed to augment the occipital bone and improve structural integrity and cosmesis. Because this is a scheduled supplement procedure addressing a known bony deficiency, an open approach to place autologous or synthetic material is performed. Typical codes: 0NU707Z, 0NU70JZ
A patient previously treated with a craniotomy develops a persistent occipital bone contour deformity and symptomatic instability months after the index surgery; during an inpatient revision the surgeon performs percutaneous endoscopic placement of a synthetic augment to reinforce the occipital bone and correct the defect. The minimally invasive percutaneous endoscopic supplement is chosen to reduce soft-tissue dissection during the revision. Typical codes: 0NU74JZ, 0NU74KZ
