2026 ICD-10-CM Diagnosis Code D00.2Carcinoma in situ of stomach

AHRQ’s CCSR groups this code into broader clinical categories.

• Esophagogastric Junction

  the area covering the terminal portion of esophagus and the beginning of stomach at the cardiac orifice.

• Pyloric Stenosis

  narrowing of the pyloric canal with varied etiology. a common form is due to muscle hypertrophy (pyloric stenosis, hypertrophic) seen in infants.

• Pylorus

  the region of the stomach at the junction with the duodenum. it is marked by the thickening of circular muscle layers forming the pyloric sphincter to control the opening and closure of the lumen.

• Bariatric Surgery

  surgical procedures aimed at affecting metabolism and producing major weight reduction in patients with morbid obesity.

• Diverticulosis, Stomach

  a pathological condition characterized by the presence of a number of gastric diverticula in the stomach.

• Diverticulum, Stomach

  saccular, outward protrusion of all or a portion of the wall of the stomach.

• Gastric Absorption

  uptake of substances via the stomach.

• Gastric Antral Vascular Ectasia

  a distinct vascular lesion in the pyloric antrum that is characterized by tortuous dilated blood vessels (ectasia) radiating outward from the pylorus. the vessel pattern resembles the stripes on the surface of a watermelon. this lesion causes both acute and chronic gastrointestinal hemorrhage.

• Gastric Dilatation

  abnormal distention of the stomach due to accumulation of gastric contents that may reach 10 to 15 liters. gastric dilatation may be the result of gastric outlet obstruction; ileus; gastroparesis; or denervation.

• Gastric Fistula

  abnormal passage communicating with the stomach.

• Gastric Stump

  that portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. it is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.

• Gastrointestinal Contents

  the contents included in all or any segment of the gastrointestinal tract.

• Receptor-Like Protein Tyrosine Phosphatases, Class 3

  a subclass of receptor-like protein tryosine phosphatases that contain a single cytosolic protein tyrosine phosphate domain and multiple extracellular fibronectin iii-like domains.

• Stomach

  an organ of digestion situated in the left upper quadrant of the abdomen between the termination of the esophagus and the beginning of the duodenum.

• Stomach Diseases

  pathological processes involving the stomach.

• Stomach Neoplasms

  tumors or cancer of the stomach.

• Stomach Rupture

  bursting of the stomach.

• Stomach Ulcer

  ulceration of the gastric mucosa due to contact with gastric juice. it is often associated with helicobacter pylori infection or consumption of nonsteroidal anti-inflammatory drugs (nsaids).

• Stomach Volvulus

  twisting of the stomach that may result in gastric ischemia and gastric outlet obstruction. it is often associated with diaphragmatic hernia.

• Stomach, Avian

  a component of the digestive system of birds which consists of the gizzard and proventriculus.

• Stomach, Ruminant

  a component of the digestive system of ruminants which consists of the abomasum; omasum; reticulum; and rumen.

Stomach Cancer

The stomach is an organ between the esophagus and the small intestine. It mixes food with stomach acid and helps digest protein. Stomach cancer mostly affects older people - two-thirds of people who have it are over age 65. Your risk of getting it is also higher if you:
