Clinical Information

• 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.

D13.1 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
393	OTHER DIGESTIVE SYSTEM DIAGNOSES WITH MCC	06	1.6196
394	OTHER DIGESTIVE SYSTEM DIAGNOSES WITH CC	06	0.9369
395	OTHER DIGESTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC	06	0.6475

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert D13.1 to ICD-9-CM

• ICD-9-CM Code: 211.1 - Benign neoplasm stomach
  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.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

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
