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 0N57 includes procedures performed to destroy all or a portion of the occipital bone in the head and facial bones. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs physical eradication of occipital bone tissue using energy, force, or a destructive agent. Accurate coding within the ICD-10-PCS 0N57 group is essential for proper inpatient reimbursement, as it captures the specific destructive procedure performed and supports clinical documentation accuracy.

Occipital Bone Destruction Procedure Overview

This procedure group includes inpatient destruction procedures targeting the occipital bone within the head and facial bones body system. These procedures use energy, force, or a destructive agent to eradicate all or part of the occipital bone. Accurate ICD-10-PCS coding is important to reflect the clinical work performed and to support appropriate inpatient reimbursement.

When to Use

Use a code from this group when the operative intent is to physically destroy all or a portion of the occipital bone rather than excise or repair it. These codes apply when destruction is accomplished by methods such as energy application, mechanical force, or other destructive agents during an inpatient procedure.

Typical Clinical Scenarios

An adult patient presents after a severe cranial osteomyelitis localized to the occipital bone unresponsive to prolonged intravenous antibiotics, with necrotic bone confirmed on imaging and intraoperative assessment. The surgical plan is to destroy the infected occipital bone tissue using direct application of energy via an open approach to eradicate residual infected bone and reduce bioburden prior to reconstruction or wound closure. This is performed in the inpatient setting due to extent of disease and need for postoperative monitoring. Typical codes: 0N570ZZ
A patient with a large, symptomatic arteriovenous malformation involving the external surface of the occipital bone presents for urgent inpatient management after hemorrhage and progressive mass effect. The surgeon uses a percutaneous technique to deliver focused destructive energy to a portion of the occipital bone to obliterate abnormal bone tissue contributing to the lesion while minimizing disruption to surrounding structures. The procedure is performed during the same hospitalization because of the acuity of neurologic symptoms. Typical codes: 0N573ZZ
A patient previously treated for occipital bone tumor with partial resection now has recurrent tumor involving residual occipital bone identified on follow-up imaging. To avoid larger open resection and because the residual lesion is accessible endoscopically, the team performs a percutaneous endoscopic destruction of the involved occipital bone to eradicate remaining tumor-involved bone during an inpatient admission for surgical management and observation. Typical codes: 0N574ZZ
