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 0CJS includes procedures performed to inspect structures in the larynx. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs visual or manual assessment of the larynx to diagnose pathology, evaluate function, or guide further treatment. Accurate coding within the ICD-10-PCS 0CJS group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Larynx Inspection Procedure Overview

This procedure group includes visually and/or manually inspecting the larynx to evaluate its structure and function within the mouth and throat body system. Procedures involve endoscopic or direct visualization techniques to assess vocal cords, surrounding tissues, and airway patency. Accurate ICD-10-PCS coding for these inspections supports correct inpatient documentation and reimbursement by reflecting the diagnostic or procedural evaluation performed.

When to Use

Use a code from this group when a clinician performs direct or endoscopic inspection of the larynx to assess vocal cords, airway patency, or mucosal lesions. These codes apply when the inspection is the primary procedure documented during the inpatient encounter.

ICD-10-PCS Codes

6 rows

ICD-10-PCS Code	Description
0CJS0ZZ	Inspection of Larynx, Open Approach
0CJS3ZZ	Inspection of Larynx, Percutaneous Approach
0CJS4ZZ	Inspection of Larynx, Percutaneous Endoscopic Approach
0CJS7ZZ	Inspection of Larynx, Via Natural or Artificial Opening
0CJS8ZZ	Inspection of Larynx, Via Natural or Artificial Opening Endoscopic
0CJSXZZ	Inspection of Larynx, External Approach

Typical Clinical Scenarios

An adult arrives to the emergency department with acute stridor and progressive respiratory distress after inhalation injury; clinicians admit the patient for airway evaluation to assess vocal cord mobility, supraglottic edema, and potential need for airway intervention. A direct visualization of the larynx at bedside or in the operating room is performed to determine airway patency and guide urgent management. Typical codes: 0CJS7ZZ, 0CJS8ZZ
A middle-aged patient is scheduled for an elective inpatient diagnostic assessment for persistent hoarseness and a suspected vocal fold lesion seen on outpatient exam; the admission is for controlled endoscopic inspection to localize and characterize the lesion prior to definitive treatment. A percutaneous endoscopic or natural-orifice endoscopic laryngoscopy is performed to document mucosal abnormalities and plan biopsy or excision. Typical codes: 0CJS4ZZ, 0CJS8ZZ
A postoperative inpatient develops new-onset dysphonia and concern for recurrent laryngeal nerve palsy after neck surgery; clinicians perform a focused inspection of the larynx to evaluate vocal cord position and motion to inform further management or rehabilitation. The inspection may be done via direct open exposure or via a transoral endoscopic approach depending on clinical access and stability. Typical codes: 0CJS0ZZ, 0CJS4ZZ
