Gastric ulcers, also known as stomach ulcers or peptic ulcers, are open sores found on the stomach lining. Ulcers happen when digestive acids eat the stomach lining due to the thin mucus layer protecting one’s stomach.
The main symptoms are usually burning or pain in the middle of the stomach. However, one may experience other symptoms besides the main symptoms, such as indigestion, heartburn, nausea, vomiting, bloating, acid reflux, anemia, not wanting to eat/feeling full quickly, or dark vomit/stool.
An infection of the bacterium Helicobacter pylori (H.pylori) or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) usually causes gastric ulcers.
To diagnose gastric ulcer, the practitioner will check the patient’s medical history, have them undergo a blood/stool/ or breath test, conduct imaging tests, and collect stomach tissue via a biopsy.
Treatments vary depending on the cause. For mild cases, treatment includes prescription medication and probiotics. Meanwhile, for severe cases, surgery may be the recommended treatment. In addition, a diet change may be recommended to the patient to eliminate the bacteria that causes gastric ulcers.

You can use a gastric ulcer ICD code once you’ve determined with tests and examinations that the patient has a stomach ulcer.

Yes, the mentioned gastric ulcer diagnosis codes are billable.

Common treatments for gastric ulcers and a possible change in diet are prescription medication and probiotics.
