GERD, or Gastroesophageal Reflux Disease, is a chronic stomach issue. It affects millions worldwide.
It is a condition whereby the stomach acid often finds its way into the esophagus, causing annoyance and uneasiness.
Correct coding is the key in medical billing and documentation, where the ICD-10 code for GERD becomes essential.
GERD ICD-10 codes help doctors accurately diagnose, leading to better treatment and billing. It does not matter whether one is coding acid reflux ICD-10 codes or other related conditions, such as hiatal hernia ICD code; proper coding is essential.
Health Med Affairs is a top Texas medical billing firm. We help healthcare providers in major cities report conditions like GERD using accurate ICD-10 codes for smooth claims processing.
Further, the complete ICD-10 code of GERD, symptoms, causes, and related conditions will be discussed below.
So, What Is GERD?
The Gastroesophageal Reflux Disease is abbreviated GERD. GERD does not entail having an occasional attack of heartburn. It is a disorder that is persistent in the sense that the acid reflux is so extreme or happens more than 2-3 times a week.
In this situation, the lower esophageal sphincter (LES) fails to hold the stomach as acid refluxes into the esophagus. The consequence of that can be:
- Harm to the esophagus and its lining
- Suffering and pain
- Difficulty swallowing
It is imperative to know GERD when diagnosing and treating it.
Main ICD-10 Code of GERD
The major ICD-10 code of Gastroesophageal reflux disease corresponds to:
K21.9: Gastroesophageal reflux disease without esophagitis
This code is used when GERD is diagnosed, but without inflammation of the esophagus. It’s one of the most commonly used GERD ICD-10 codes in medical billing.
At Health Med Affairs, we regularly assist providers in applying the proper ICD-10 GERD codes during the billing process, helping them improve reimbursement outcomes.
Detailed ICD-10 Codes for GERD and Related Variants
In the ICD-10-CM, GERD is included in the following categories:
- Chapter XI: Diseases of the Digestive System (K00–K95)
- Subsection: K20–K31, Diseases of the esophagus, stomach, and duodenum
K21: Gastroesophageal Reflux Disease (GERD)
K21.00: GERD with esophagitis
Utilized when the circumstance has produced apparent redness (esophagitis) in the esophagus.
K21.9: GERD without esophagitis
Applied when GERD is expressed by symptoms, but without any lesions in the esophagus.
For chronic acid reflux, Health Med Affairs helps providers with correct GERD ICD-10 codes and compliance.
