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 0NT7 includes procedures performed to resect bone in the occipital region of the skull. These ICD-10-PCS codes are used for inpatient documentation when an open surgical removal of occipital bone tissue is performed for therapeutic, diagnostic, or decompressive purposes. Accurate coding within the ICD-10-PCS 0NT7 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Occipital Bone Resection Procedure Overview

Procedures in this group involve open surgical resection of part or all of the occipital bone and target the head and facial bones body system. These resection procedures remove bone tissue for diagnostic, therapeutic, or decompressive reasons. Accurate ICD-10-PCS coding of these open resections is important for inpatient reimbursement because it documents the specific operative action and anatomical site.

Typical Clinical Scenarios

An elderly patient presents emergently after a high-energy motor vehicle collision with depressed occipital skull fractures and progressive neurological decline from posterior fossa compression. The patient is taken to the operating room for open decompression and removal of fractured occipital bone fragments to relieve mass effect and allow brain swelling control; inpatient documentation captures the open resection of occipital bone for acute management. Typical codes: 0NT70ZZ
A middle-aged patient with refractory posterior cranial osteomyelitis involving the occipital bone after prior sinus infection undergoes planned surgical debridement because antibiotics alone failed to eradicate infected bone. Inpatient care is required for perioperative monitoring, intravenous antibiotics, and wound management while the surgeon performs an open resection of involved occipital bone to remove necrotic, infected tissue. Typical codes: 0NT70ZZ
A young adult with progressive occipital meningioma causing focal symptoms is scheduled for subtotal tumor resection that necessitates removal of part of the occipital bone to access and resect involved skull margins; this elective inpatient procedure includes open bone resection for oncologic clearance and reconstruction planning. Typical codes: 0NT70ZZ
