ICD-10 Codes for GERD – Gastroesophageal Reflux Disease

What is GERD?

GERD stands for Gastroesophageal Reflux Disease, which is a chronic digestive disorder that occurs when stomach acid or bile flows back up into the esophagus. Normally, a ring of muscle at the bottom of the esophagus, called the lower esophageal sphincter (LES), prevents acid from flowing back up into the esophagus.

In people with GERD, the LES doesn’t function properly, allowing stomach acid and other contents to flow back up into the esophagus. This can cause symptoms such as heartburn, acid regurgitation, chest pain, difficulty swallowing, and chronic cough.

GERD is a relatively common condition, affecting up to 20% of adults in Western countries. While occasional acid reflux is normal, frequent or persistent acid reflux may indicate GERD and require medical attention. Treatment may include lifestyle modifications, such as weight loss and avoiding trigger foods, as well as medication or surgery in severe cases.

Are there any Specific Stages to Identify GERD?

There are no specific stages of GERD, but physicians may use various methods to diagnose and identify and then code the corresponding GERD ICD-10 Codes for medical billing services and reimburesement purposes. These methods may include:

  1. Evaluation of symptoms: Physicians may ask the patient about their symptoms, including heartburn, regurgitation, chest pain, difficulty swallowing, and chronic cough.
  2. Physical examination: Physicians may perform a physical examination to look for signs of GERD, such as inflammation of the throat or esophagus, or a hiatal hernia.
  3. Endoscopy: In an endoscopy, a flexible tube with a camera is inserted into the esophagus and stomach to look for signs of inflammation, ulcers, or other damage to the esophagus. This is considered the gold standard for diagnosing GERD.
  4. Esophageal pH monitoring: A small device is placed in the esophagus to measure the level of acidity and determine the frequency and duration of acid reflux.
  5. Manometry: This test measures the strength and coordination of the muscles in the esophagus and LES.
  6. Barium swallow: In this test, the patient swallows a liquid that contains barium, which shows up on X-rays and can help identify structural problems in the esophagus or stomach.

Based on the results of these tests, physicians can determine the severity of GERD and develop an appropriate treatment plan. Treatment may include lifestyle modifications, such as avoiding trigger foods and losing weight, and medications to reduce acid production or improve the function of the LES. In severe cases, surgery may be necessary.

ICD-10 Codes & GERD Guidelines

The ICD-10 codes for GERD are as follows:

  • K21.9    GERD
  • K21.00 GERD With esophagitis without bleeding
  • K21.01  GERD With esophagitis with bleeding
  • P78.83  Neonatal esophageal reflux

The codes above are used to specify the diagnosis of GERD based on the presence or absence of esophagitis.

According to the ICD-10 coding guidelines, when coding for GERD, it is important to document the type of reflux disease, any associated complications or manifestations, and the severity of the condition. In addition, the guidelines recommend coding any coexisting conditions that may be contributing to or affecting the GERD, such as hiatal hernia.

It is also important to note that if the patient has Barrett’s esophagus, a condition in which the lining of the esophagus changes to resemble the lining of the intestine, a separate code should be used to indicate this condition.

Overall, accurate coding of GERD is important to ensure appropriate treatment and reimbursement for healthcare services provided to patients with this condition.

CPT Codes for GERD

The following are some common CPT codes (Current Procedural Terminology) used for the diagnosis and treatment of GERD (Gastroesophageal Reflux Disease):

  1. Upper gastrointestinal (GI) endoscopy: CPT codes 43239-43259 This procedure involves inserting a flexible tube with a camera into the esophagus and stomach to look for signs of inflammation, ulcers, or other damage to the esophagus. It is considered the gold standard for diagnosing GERD.
  2. Esophageal pH monitoring: CPT codes 91034-91035 This procedure involves placing a small device in the esophagus to measure the level of acidity and determine the frequency and duration of acid reflux.
  3. Manometry: CPT codes 91122-91123 This test measures the strength and coordination of the muscles in the esophagus and LES.
  4. Barium swallow: CPT codes 74220-74230 In this test, the patient swallows a liquid that contains barium, which shows up on X-rays and can help identify structural problems in the esophagus or stomach.
  5. Ambulatory reflux monitoring: CPT codes 91038-91039 This test involves placing a small device in the esophagus to monitor reflux over a 24-hour period.

It is important to note that CPT codes may vary depending on the specific procedure and the individual healthcare provider. It is recommended to consult with your healthcare provider or insurance company to confirm the appropriate CPT codes for your specific situation.

Causes and Symptoms of GERD

GERD (Gastroesophageal Reflux Disease) is a chronic digestive disorder that occurs when stomach acid or bile flows back up into the esophagus, causing irritation and inflammation. The exact cause of GERD is not always known, but some factors that may contribute to the development of the condition include:

  • Weakened lower esophageal sphincter (LES) muscle: The LES is a ring of muscle at the bottom of the esophagus that normally prevents stomach acid from flowing back up into the esophagus. A weakened LES can allow acid to flow back up, causing symptoms of GERD.
  • Hiatal hernia: A hiatal hernia occurs when the stomach bulges up into the chest through an opening in the diaphragm, which can weaken the LES and allow acid to flow back up into the esophagus.
  • Delayed stomach emptying: When the stomach takes longer than normal to empty its contents, this can increase the risk of acid reflux.
  • Obesity: Being overweight or obese can increase the pressure on the stomach and LES, making acid reflux more likely.

Some common symptoms of GERD include:

  • Heartburn: A burning sensation in the chest that often occurs after eating or at night.
  • Regurgitation: The sensation of stomach acid or bile flowing back up into the throat or mouth.
  • Chest pain: Chest pain or discomfort that can sometimes be mistaken for a heart attack.
  • Difficulty swallowing: A feeling of food getting stuck in the throat or chest.
  • Chronic cough: A persistent cough that is not caused by a respiratory infection.

If left untreated, GERD can lead to complications such as esophagitis (inflammation of the esophagus), ulcers, strictures (narrowing of the esophagus), and Barrett’s esophagus (a condition in which the lining of the esophagus changes to resemble the lining of the intestine).
