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 0CYS includes procedures performed to transplant all or part of the larynx in the mouth and throat. These ICD-10-PCS codes are used for inpatient documentation when a laryngeal transplant from another individual or animal is performed to replace or restore laryngeal structure and/or function. Accurate coding within the ICD-10-PCS 0CYS group is essential for proper inpatient reimbursement, as it captures the transplantation procedure performed and determines appropriate case mix and payment.

Larynx Transplantation Procedure Overview

This procedure group covers transplantation of the larynx, targeting the mouth and throat body system. These procedures involve placing all or part of a larynx from another individual or animal to restore the structure and/or function of the recipient's larynx. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it captures the complex nature of transplantation and supports appropriate case mix assignment and payment.

When to Use

Use a code from this group when an inpatient undergoes placement of a donor larynx or laryngeal tissue to replace or restore laryngeal anatomy and/or function. Do not use these codes for other laryngeal procedures such as resection, repair, or reconstruction that are not transplantations.

Typical Clinical Scenarios

An adult patient with catastrophic laryngeal trauma from a motor vehicle collision presents emergently with complete loss of laryngeal structure and airway compromise despite prior airway stabilization; the patient is admitted for definitive reconstructive replacement using donor laryngeal tissue to restore airway and phonatory function, performed via an open surgical approach. Typical codes: 0CYS0Z0, 0CYS0Z1
A middle-aged patient with end-stage progressive laryngeal destruction from radiation necrosis after prior treatment for laryngeal carcinoma is scheduled for an elective inpatient procedure to replace the nonfunctional larynx with a donor graft to reestablish airway patency and voice capability; the planned operation is performed open in a controlled surgical setting. Typical codes: 0CYS0Z0, 0CYS0Z1
A younger patient with severe laryngeal failure after multiple failed reconstructive surgeries and chronic aspiration is admitted for a staged revision transplant; the surgical team performs an open transplant of donor laryngeal tissue to replace the previously operated native larynx and address recurrent functional failure. Typical codes: 0CYS0Z0, 0CYS0Z1
