2024 ICD-10-CM Diagnosis Code K27.9

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Drug-induced peptic ulcer
• Exacerbation of peptic ulcer
• Peptic anastomotic ulcer
• Peptic ulcer
• Peptic ulcer with obstruction
• Peptic ulcer without hemorrhage AND without perforation
• Peptic ulcer without hemorrhage AND without perforation
• Peptic ulcer without hemorrhage AND without perforation but with obstruction
• Peptic ulcer without hemorrhage, without perforation AND without obstruction
• Stress ulcer
• Stress ulcer of stomach

Clinical Information

• Peptic Ulcer

  ulcer that occurs in the regions of the gastrointestinal tract which come into contact with gastric juice containing pepsin and gastric acid. it occurs when there are defects in the mucosa barrier. the common forms of peptic ulcers are associated with helicobacter pylori and the consumption of nonsteroidal anti-inflammatory drugs (nsaids).

• Peptic Ulcer Hemorrhage

  bleeding from a peptic ulcer that can be located in any segment of the gastrointestinal tract.

• Peptic Ulcer Perforation

  penetration of a peptic ulcer through the wall of duodenum or stomach allowing the leakage of luminal contents into the peritoneal cavity.

K27.9 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
380	COMPLICATED PEPTIC ULCER WITH MCC	06	1.9485
381	COMPLICATED PEPTIC ULCER WITH CC	06	1.073
382	COMPLICATED PEPTIC ULCER WITHOUT CC/MCC	06	0.7571
383	UNCOMPLICATED PEPTIC ULCER WITH MCC	06	1.3982
384	UNCOMPLICATED PEPTIC ULCER WITHOUT MCC	06	0.8757

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 K27.9 to ICD-9-CM

• ICD-9-CM Code: 533.90 - Peptic ulcer NOS
  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.

Patient Education

Peptic 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.
