K28.9 is a billable diagnosis code used to specify a medical diagnosis of gastrojejunal ulcer, unspecified as acute or chronic, without hemorrhage or perforation. The code K28.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code K28.9 might also be used to specify conditions or terms like anastomotic ulcer due to zollinger-ellison syndrome, erosion of gastrointestinal anastomosis, gastrocolic ulcer, gastrointestinal ulcer, gastrojejunal ulcer , gastrojejunal ulcer without hemorrhage and without perforation, etc.
Unspecified diagnosis codes like K28.9 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.

Information for Patients
Also called: Duodenal ulcer, Gastric ulcer, Stomach ulcer, Ulcer
A peptic ulcer is a sore in the lining of your stomach or your duodenum, the first part of your small intestine. A burning stomach pain is the most common symptom. The pain
- Starts between meals or during the night
- Briefly stops if you eat or take antacids
- Lasts for minutes to hours
- Comes and goes for several days or weeks
Peptic ulcers happen when the acids that help you digest food damage the walls of the stomach or duodenum. The most common cause is infection with a bacterium called Helicobacter pylori. Another cause is the long-term use of nonsteroidal anti-inflammatory medicines (NSAIDs) such as aspirin and ibuprofen. Stress and spicy foods do not cause ulcers, but can make them worse.
To see if you have an H. pylori infection, your doctor will test your blood, breath, or stool. Your doctor also may look inside your stomach and duodenum by doing an endoscopy or x-ray.
Peptic ulcers will get worse if not treated. Treatment may include medicines to reduce stomach acids or antibiotics to kill H. pylori. Antacids and milk can't heal peptic ulcers. Not smoking and avoiding alcohol can help. You may need surgery if your ulcers don't heal.
