ICD-10-PCS Code For Ethmoid Bone Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0NCG includes procedures performed to remove solid matter from structures in the ethmoid bone, left. These ICD-10-PCS codes are used for inpatient documentation when extirpation of solid material from the left ethmoid bone is performed to treat infection, trauma, or obstructive pathology. Accurate coding within the ICD-10-PCS 0NCG group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Ethmoid Bone Left Extirpation Procedure Overview

Procedures in this group involve the extirpation of solid matter from the left ethmoid bone within the head and facial bones body system. These operations remove foreign material, bone fragments, or pathological deposits from the ethmoid bone to restore function or relieve symptoms. Accurate ICD-10-PCS coding of these extirpation procedures supports correct inpatient documentation and reimbursement by reflecting the specific body part and operation performed.

Typical Clinical Scenarios

An adult presents to the emergency department after facial trauma from a motor vehicle collision with persistent nasal obstruction and imaging showing displaced bone fragments and retained debris within the left ethmoid air cells. Because of ongoing airway compromise and risk of infection, the patient is taken to the operating room for direct surgical removal of the bone fragments and contaminant material through an open approach to ensure complete debridement. Extirpation of solid matter from the left ethmoid bone is performed to restore sinus drainage and prevent further intracranial or orbital complications. Typical codes: 0NCG0ZZ
A middle-aged patient with chronic left-sided sinusitis unresponsive to prolonged medical therapy and outpatient endoscopic interventions is admitted electively for definitive management. Preoperative imaging demonstrates retained polypoid and inspissated material within the left ethmoid bone requiring targeted removal under visualization. A percutaneous endoscopic extirpation of the matter from the left ethmoid bone is performed during the inpatient admission to relieve obstruction and improve sinus ventilation. Typical codes: 0NCG4ZZ
A patient with a prior minimally invasive drainage of an ethmoid abscess returns with recurrent localized infection and persistent radiographic collection within the left ethmoid bone after failed percutaneous therapy. Because the prior percutaneous attempt did not fully evacuate dense purulent material and organized debris, a repeat percutaneous extirpation is performed to remove remaining solid material and allow definitive resolution of the infection. The procedure targets the left ethmoid bone and uses a percutaneous non-endoscopic approach. Typical codes: 0NCG3ZZ
