The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: NEO073

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

• 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.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

ICD-9-CM: 211.1

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

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.

Filter table of neoplasms:

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 a 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
