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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0C7M includes procedures performed to dilate structures in the pharynx. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs an endoscopic or mechanical expansion of the pharyngeal lumen to relieve stenosis or obstruction. Accurate coding within the ICD-10-PCS 0C7M group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Pharynx Dilation Procedure Overview

This procedure group includes dilation procedures performed on the pharynx within the mouth and throat body system. These procedures involve expanding the lumen or orifice of the pharynx to improve patency and relieve obstructive symptoms. Accurate coding of pharyngeal dilation is important for inpatient reimbursement because it documents the specific root operation and anatomical target, which affects case mix and payment determinations.

When to Use

Use a code from this group when an inpatient procedure expands the pharyngeal lumen or orifice to relieve narrowing or obstruction. This includes endoscopic or mechanical approaches performed to restore patency in the pharynx.

ICD-10-PCS Codes

4 rows

ICD-10-PCS Code	Description
0C7M7DZ	Dilation of Pharynx with Intraluminal Device, Via Natural or Artificial Opening
0C7M7ZZ	Dilation of Pharynx, Via Natural or Artificial Opening
0C7M8DZ	Dilation of Pharynx with Intraluminal Device, Via Natural or Artificial Opening Endoscopic
0C7M8ZZ	Dilation of Pharynx, Via Natural or Artificial Opening Endoscopic

Typical Clinical Scenarios

An elderly patient with rapidly progressive dysphagia and drooling presents to the hospital after aspiration pneumonia workup reveals severe pharyngeal narrowing from radiation-induced fibrosis following prior head and neck cancer treatment. The patient is admitted for airway protection, IV antibiotics, and definitive management to restore pharyngeal patency to allow swallow function and reduce aspiration risk; an intraluminal dilation is performed at bedside or in the OR to mechanically expand the stenotic pharyngeal lumen. Typical codes: 0C7M7DZ, 0C7M8DZ
A middle-aged patient with a history of chronic reflux and recurrent pharyngitis develops progressive throat tightness and odynophagia; after outpatient evaluation demonstrates a focal pharyngeal web causing intermittent obstruction, the case is scheduled as an elective inpatient endoscopic procedure to dilate the web under controlled anesthesia for symptomatic relief and to prevent feeding compromise. Typical codes: 0C7M8ZZ, 0C7M8DZ
A postoperative patient develops immediate pharyngeal edema and functional narrowing after transoral surgery, leading to inability to swallow secretions and escalating respiratory distress; the patient is taken to the operating room for prompt dilation of the pharyngeal lumen to reestablish adequate opening and facilitate enteral access or extubation. Typical codes: 0C7M7ZZ, 0C7M8ZZ
