ICD-10-PCS Code For Larynx: Procedure Code Group Overview

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

Larynx Insertion Procedure Overview

Procedures in this group involve insertion of nonbiological appliances into the larynx within the mouth and throat body system to monitor, assist, perform, or prevent a physiological function without replacing a body part. These operations target the larynx and are coded using the Medical and Surgical section of the International Classification of Diseases, Tenth Revision, Procedure Coding System. Accurate selection of the correct code supports proper inpatient documentation and reimbursement by reflecting the specific insertion procedure performed.

ICD-10-PCS Code	Description
0CHS01Z	Insertion of Radioactive Element into Larynx, Open Approach
0CHS0YZ	Insertion of Other Device into Larynx, Open Approach
0CHS31Z	Insertion of Radioactive Element into Larynx, Percutaneous Approach
0CHS3YZ	Insertion of Other Device into Larynx, Percutaneous Approach
0CHS71Z	Insertion of Radioactive Element into Larynx, Via Natural or Artificial Opening
0CHS7YZ	Insertion of Other Device into Larynx, Via Natural or Artificial Opening

0CHS8YZ	Insertion of Other Device into Larynx, Via Natural or Artificial Opening Endoscopic

Typical Clinical Scenarios

An elderly nursing home resident with advanced Parkinson disease develops progressive difficulty protecting the airway with recurrent aspiration and noisy breathing; during an inpatient admission for aspiration pneumonia and failed extubation, the team places a laryngeal airway monitoring or assist device to support airway patency and reduce aspiration risk. A nonbiological appliance is inserted into the larynx via a natural or artificial opening to assist physiological function. Typical codes: 0CHS71Z, 0CHS7YZ
A middle-aged patient with recurrent vocal cord paralysis undergoes an elective operative admission for placement of an implanted laryngeal pacing/monitoring device to improve vocal fold function and airway protection; the device is introduced endoscopically under general anesthesia to perform monitoring and assist function without replacing the larynx. Typical codes: 0CHS81Z, 0CHS8YZ
A trauma patient with penetrating neck injury and significant laryngeal edema is taken to the operating room emergently after failed noninvasive airway attempts; a nonbiological appliance is inserted into the larynx through a percutaneous approach to secure and monitor the airway while definitive repairs are planned. Typical codes: 0CHS31Z, 0CHS3YZ
