5 ICD-10 Codes for Gastroesophageal Reflux

Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the esophagus, causing irritation and discomfort. Below are five ICD-10 codes related to gastroesophageal reflux, each addressing specific aspects of the condition:

1. K21.9 - Gastro-esophageal reflux disease without esophagitis
   This code is used when a patient has GERD without evidence of inflammation or damage to the esophagus. It is a general diagnosis for reflux symptoms like heartburn, regurgitation, or acid indigestion.

2. K21.0 - Gastro-esophageal reflux disease with esophagitis
   This code is used when GERD is accompanied by esophagitis, an inflammation of the esophagus caused by prolonged exposure to stomach acid. Symptoms may include severe heartburn, difficulty swallowing, or chest pain.

3. K21.8 - Other gastro-esophageal reflux disease
   This code is used for less common or unspecified forms of GERD, such as reflux associated with respiratory symptoms (e.g., chronic cough or asthma) or other atypical presentations.

4. R12 - Heartburn
   This code is used to specifically document heartburn, a common symptom of GERD. It may be used in conjunction with GERD codes when heartburn is the primary complaint or a significant symptom.

5. K52.81 - Barrett’s esophagus
   While not a direct GERD code, Barrett’s esophagus is a serious complication of chronic GERD, where the lining of the esophagus changes due to prolonged acid exposure. This code is used when Barrett’s esophagus is diagnosed in a patient with a history of GERD.
