Code Classification

  • Diseases of the digestive system
    (K00–K95)
    • Diseases of esophagus, stomach and duodenum
      (K20-K31)
      • Esophagitis
        (K20)

K20.9 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of esophagitis, unspecified. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like K20.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to Esophagitis, unspecified

Non-specific codes like K20.9 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for esophagitis, unspecified:

  • Use K20.90 for Esophagitis, unspecified without bleeding - BILLABLE CODE

  • Use K20.91 for Esophagitis, unspecified with bleeding - BILLABLE CODE

Clinical Classification

Clinical Information

  • Eosinophilic Esophagitis

    chronic esophagitis characterized by esophageal mucosal eosinophilia. it is diagnosed when an increase in eosinophils are present over the entire esophagus. the reflux symptoms fail to respond to proton pump inhibitors treatment, unlike in gastroesophageal reflux disease. the symptoms are associated with ige-mediated hypersensitivity to food or inhalant allergens.
  • Esophagitis

    inflammation, acute or chronic, of the esophagus caused by bacteria, chemicals, or trauma.
  • Esophagitis, Peptic

    inflammation of the esophagus that is caused by the reflux of gastric juice with contents of the stomach and duodenum.

Convert K20.9 to ICD-9-CM

  • ICD-9-CM Code: 530.10 - Esophagitis, unspecified
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
  • ICD-9-CM Code: 530.12 - Acute esophagitis
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Esophagus Disorders

The esophagus is the muscular tube that carries food and liquids from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot, or too cold. You may also notice it when something is wrong. You may feel pain or have trouble swallowing.

The most common problem with the esophagus is GERD (gastroesophageal reflux disease). With GERD, a muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it. Over time, GERD can cause damage to the esophagus.

Other problems include heartburn, cancer, and eosinophilic esophagitis. Doctors may use various tests to make a diagnosis. These include imaging tests, an upper endoscopy, and a biopsy.

Treatment depends on the problem. Some problems get better with over-the-counter medicines or changes in diet. Others may need prescription medicines or surgery.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
