ICD-10 code K31.84 for Gastroparesis. Medical coding concept for healthcare records and billing.

Gastroparesis ICD 10 Code: Diagnosis and Treatment

Gastroparesis is a complex medical condition that demands thorough understanding, especially when it comes to its classification under the International Classification of Diseases, Tenth Revision (ICD-10). In this detailed guide, we delve into the nuances of gastroparesis ICD-10, offering insights that go beyond the surface-level understanding.

What is Gastroparesis?

Gastroparesis, also known as delayed gastric emptying, occurs when the muscles in the stomach fail to function properly, leading to slow or incomplete emptying of food into the small intestine. This delay can result in a variety of symptoms, including:

  1. Nausea and Vomiting: Patients with gastroparesis often experience persistent nausea and may vomit undigested food.
  2. Abdominal Pain: Individuals may suffer from discomfort or pain in the abdominal region.
  3. Feeling Full Quickly: Gastroparesis can cause an early sensation of fullness even after consuming small amounts of food.
  4. Weight Loss: Due to the difficulty in consuming an adequate amount of nutrients, weight loss is a common consequence of gastroparesis.
  5. Heartburn or GERD: Gastroesophageal reflux disease (GERD) symptoms may worsen as a result of delayed stomach emptying.

Gastroparesis ICD-10 Coding

When it comes to medical coding, accuracy is paramount. In the realm of gastroenterology, accurate coding for gastroparesis is crucial for streamlined healthcare processes. The ICD-10 code for gastroparesis is K31.84. This specific code aids in identifying and categorizing the condition for billing, medical records, and statistical purposes.

Decoding K31.84: Understanding the Components

Breaking down the K31.84 code, each element plays a vital role in precisely defining gastroparesis within the ICD-10 framework:

K – Diseases of the Digestive System

The initial character ‘K’ designates the code under the category of diseases of the digestive system. This helps in quickly locating gastroparesis within the broader classification of gastrointestinal disorders.

31 – Diseases of Esophagus, Stomach, and Duodenum

The numeric characters ’31’ narrow down the focus to diseases specifically related to the esophagus, stomach, and duodenum. Gastroparesis falls within this subset, emphasizing its impact on stomach function.

84 – Other Diseases of Stomach and Duodenum

The final characters ’84’ pinpoint gastroparesis as an ailment falling under the broader category of other diseases affecting the stomach and duodenum. This specificity aids healthcare professionals in precisely identifying and treating the condition.

Causes of Gastroparesis

Several factors can contribute to the development of gastroparesis, including:

  1. Diabetes: The most common cause of gastroparesis is diabetes mellitus, where high blood sugar levels can damage the vagus nerve, which controls stomach muscles.
  2. Post-Surgical Complications: Certain abdominal surgeries, particularly those involving the stomach or vagus nerve, can lead to gastroparesis.
  3. Viral Infections: Some viral infections can affect the nerves in the stomach, leading to gastroparesis.
  4. Medications: Certain medications, such as narcotics and some antidepressants, can contribute to delayed gastric emptying.
  5. Idiopathic Gastroparesis: In some cases, the cause of gastroparesis remains unknown, leading to idiopathic gastroparesis.

Diagnosis and Evaluation

Diagnosing gastroparesis involves a combination of medical history, physical examination, and various tests. Common diagnostic procedures include:

  1. Gastric Emptying Study: This test involves consuming a meal containing a small amount of radioactive material, which allows the healthcare provider to monitor the rate at which the stomach empties.
  2. Upper Endoscopy: A flexible tube with a camera is inserted through the mouth to examine the stomach lining and rule out other potential causes of symptoms.
  3. Blood Tests: Blood tests can help identify underlying conditions such as diabetes or infection.
  4. Imaging Studies: X-rays or other imaging studies may be conducted to visualize the stomach and surrounding structures.

Treatment Options for Gastroparesis

Managing gastroparesis often involves a combination of dietary changes, medications, and, in severe cases, surgical interventions. Treatment options include:

  1. Dietary Modifications: Eating smaller, more frequent meals and avoiding high-fiber and high-fat foods can help alleviate symptoms.
  2. Medications: Prokinetic medications, such as metoclopramide, can stimulate stomach contractions and improve emptying.
  3. Botulinum Toxin Injections: In some cases, injections of botulinum toxin can be used to relax the pyloric sphincter and facilitate stomach emptying.
  4. Electrical Stimulation: Gastric electrical stimulation involves the use of a device that delivers electrical impulses to the stomach muscles, promoting motility.
  5. Surgical Options: In severe cases, surgical interventions, such as gastric bypass or jejunotomy tube placement, may be considered.


The complicated illness known as gastroparesis can have a major negative effect on a person’s quality of life. It is critical that patients and healthcare professionals alike comprehend the signs, causes, and available treatments. In order to properly document and categorise gastroparesis and ensure appropriate billing and communication within the healthcare system, the ICD-10 coding system is essential. It is anticipated that as research moves forward, new understandings and therapies may surface, providing better results for people dealing with this difficult ailment.
