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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0NH1 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent physiological functions in the frontal bone. These ICD-10-PCS codes are used for inpatient documentation when a device is placed in the frontal bone to provide monitoring, assistive function, or physiologic support without replacing the bone. Accurate coding within the ICD-10-PCS 0NH1 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Frontal Bone Insertion Procedure Overview

This procedure group covers insertion procedures involving the frontal bone within the head and facial bones body system. These procedures place nonbiological appliances that monitor, assist, perform, or prevent physiological functions without replacing the frontal bone. Accurate coding is important for inpatient reimbursement because it documents the specific insertion performed and supports appropriate case mix assignment and payment.

When to Use

Use a code from this group when an appliance is placed into or on the frontal bone to perform monitoring, assistive, or preventive physiological functions. Do not use these codes for procedures that replace the frontal bone or for implantations that constitute prosthetic replacement.

Typical Clinical Scenarios

An adult patient presents after a high-speed motor vehicle collision with displaced fractures of the frontal bone and associated dural tenting; the patient is admitted for neurosurgical and craniofacial stabilization to protect underlying brain tissue and restore skull contour. A nonbiological internal fixation appliance is placed into the frontal bone via an open cranioplasty approach to monitor and assist cranial stability during the acute inpatient recovery period. Typical codes: 0NH104Z
An elderly patient with osteoporosis develops a progressive, symptomatic cranial defect over the frontal bone following prior trauma; after multidisciplinary evaluation, the team plans a minimally invasive percutaneous placement of an internal fixation device to reinforce the frontal bone and provide structural support without replacing the bone. The patient is admitted for the elective, image-guided percutaneous procedure to reduce risk of further collapse and to support neurologic function monitoring during recovery. Typical codes: 0NH134Z
A middle-aged patient with a chronic frontal sinus wound and prior percutaneous hardware placement experiences recurrent instability and suboptimal device position; during inpatient revision, the surgical team performs a percutaneous endoscopic procedure to reposition or insert a new internal fixation appliance into the frontal bone to restore stability and permit ongoing physiologic monitoring and protection. Typical codes: 0NH144Z
