Code Classification

  • Diseases of the digestive system
    (K00–K95)
    • Diseases of esophagus, stomach and duodenum
      (K20-K31)
      • Gastritis and duodenitis
        (K29)

K29.70 is a billable diagnosis code used to specify a medical diagnosis of gastritis, unspecified, without bleeding. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like K29.70 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.

Clinical Classification

Clinical Information

  • Gastritis

    inflammation of the gastric mucosa, a lesion observed in a number of unrelated disorders.
  • Gastritis, Atrophic

    gastritis with atrophy of the gastric mucosa, the gastric parietal cells, and the mucosal glands leading to achlorhydria. atrophic gastritis usually progresses from chronic gastritis.
  • Gastritis, Hypertrophic

    gastritis with hypertrophy of the gastric mucosa. it is characterized by giant gastric folds, diminished acid secretion, excessive mucus secretion, and hypoproteinemia. symptoms include vomiting; diarrhea; and weight loss.
  • Gastric Mucosa

    lining of the stomach, consisting of an inner epithelium, a middle lamina propria, and an outer muscularis mucosae. the surface cells produce mucus that protects the stomach from attack by digestive acid and enzymes. when the epithelium invaginates into the lamina propria at various region of the stomach (cardia; gastric fundus; and pylorus), different tubular gastric glands are formed. these glands consist of cells that secrete mucus, enzymes, hydrochloric acid, or hormones.
  • Erosive Gastritis

    gastritis that is characterized by erosion of the mucosal surface.
  • Cytomegaloviral Gastritis|CMV Gastritis|CMV-Related Gastritis|Cytomegalovirus Gastritis|Cytomegalovirus-Related Gastritis

    inflammation of stomach that is associated with cytomegalovirus.
  • Viral Gastritis

    inflammation of the stomach resulting from viral infection.

Patient Education


Stomach Disorders

Your stomach is an organ between your esophagus and small intestine. It is where digestion of protein begins. The stomach has three tasks. It stores swallowed food. It mixes the food with stomach acids. Then it sends the mixture on to the small intestine.

Most people have a problem with their stomach at one time or another. Indigestion and heartburn are common problems. You can relieve some stomach problems with over-the-counter medicines and lifestyle changes, such as avoiding fatty foods or eating more slowly. Other problems like peptic ulcers or GERD require medical attention.

You should see a doctor if you have any of the following:

  • Blood when you have a bowel movement
  • Severe abdominal pain
  • Heartburn not relieved by antacids
  • Unintended weight loss
  • Ongoing vomiting or diarrhea

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.
