Laryngeal Reflux ICD 10: Understanding Diagnosis And Treatment Options

What is Laryngeal Reflux ICD-10?

Laryngeal reflux, also known as laryngopharyngeal reflux (LPR), is a condition where stomach acid flows back up into the larynx (voice box) and pharynx (throat). This can cause irritation and inflammation in the tissues of the throat and voice box, leading to symptoms such as hoarseness, throat clearing, coughing, and a sensation of a lump in the throat.

In terms of MS-DRG, laryngeal reflux falls under DRG 469 – Major Joint Replacement or Reattachment of Lower Extremity without MCC (Major Complications or Comorbidities). This is important for healthcare providers and hospitals when billing for services related to the treatment of laryngeal reflux.

Prior to the implementation of ICD-10, laryngeal reflux was classified under the ICD-9 code 478.79. Healthcare providers may still use this code for historical data or certain circumstances where ICD-9 codes are required.

The classification of laryngeal reflux has evolved over time, with changes in the coding system to provide more specific and accurate classifications for medical conditions. The transition from ICD-9 to ICD-10 was a significant change in the healthcare industry.

Approximate Synonyms

Other terms that may be used interchangeably with laryngeal reflux include extraesophageal reflux, silent reflux, and throat reflux. These terms all refer to the same condition of stomach acid irritating the tissues of the throat and larynx.

Clinical Information

Laryngeal reflux is a common condition that can be chronic and persistent. It is often associated with gastroesophageal reflux disease (GERD), a condition where stomach acid flows back into the esophagus. LPR may present with atypical symptoms such as throat discomfort, chronic cough, and voice changes.


The primary cause of laryngeal reflux is the malfunction of the lower esophageal sphincter, a ring of muscle that normally keeps stomach acid from flowing back up into the esophagus. When this muscle is weak or relaxes inappropriately, acid can reach the throat and larynx.


Common symptoms of laryngeal reflux include hoarseness, chronic cough, throat clearing, a sensation of a lump in the throat, and difficulty swallowing. These symptoms may worsen after eating, lying down, or with certain activities that increase intra-abdominal pressure.


Diagnosing laryngeal reflux usually involves a combination of patient history, physical examination, and diagnostic tests. These tests may include laryngoscopy, pH monitoring, and upper endoscopy to evaluate the tissues of the throat and larynx, as well as the presence of acid reflux.


Treatment for laryngeal reflux focuses on reducing the amount of acid in the stomach and preventing it from reaching the throat and larynx. This may involve lifestyle modifications, such as dietary changes, weight loss, and avoiding trigger foods, as well as medications to reduce acid production and promote healing of the tissues.


Laryngeal reflux is a common condition that can cause significant discomfort and affect the quality of life for individuals. Understanding the ICD-10 code and related information can help healthcare providers accurately diagnose and treat this condition to improve patient outcomes.
