Peptic ulcers are painful open sores that form on the inner lining of the stomach or the upper part of the small intestine. They develop when digestive acids erode the protective lining, creating wounds that can cause discomfort and, in some cases, bleeding. Accurate medical coding is essential for ensuring that healthcare providers receive appropriate reimbursement and maintain compliance with regulatory requirements. For conditions like peptic ulcer disease, which can present with varying severity and complications, precise peptic ulcer ICD-10 coding is important for clinical accuracy, billing efficiency, and regulatory compliance. This post provides an overview of peptic ulcer symptoms, diagnosis, and how to assign the correct ICD-10 codes, while also discussing documentation requirements and the benefits of partnering with medical billing experts.

Understanding Peptic Ulcer Disease
Peptic ulcer disease refers to sores or lesions that develop in the lining of the stomach, duodenum, or esophagus due to the corrosive effects of stomach acid and pepsin.
Peptic ulcer disease classification is as follows:
- Gastric Ulcers – Occur in the stomach lining.
- Duodenal Ulcers – Found in the first part of the small intestine.
- Esophageal Ulcers – Less common; occur in the esophagus.
Infection with the bacterium Helicobacter pylori (H. pylori) and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) are the primary causes of peptic ulcers. Several other factors such as family history of ulcers, stress, excessive alcohol consumption, smoking, and illnesses such as liver, kidney or lung disease, can increase the risk of this condition.
Common Symptoms of Peptic Ulcer Disease
While some individuals remain asymptomatic, common symptoms include:
- Burning or gnawing abdominal pain, often between meals or at night
- Bloating, belching, and nausea
- Vomiting (sometimes with blood)
- Unexplained weight loss
- Black, tarry stools (indicating gastrointestinal bleeding)
Recognizing these symptoms promptly is critical because complications such as bleeding, perforation, and gastric outlet obstruction require urgent intervention.
Diagnosis of Peptic Ulcer Disease
Gastroenterologists perform a detailed medical history evaluation and physical evaluation to detect peptic ulcer. Diagnosis typically involves –
- Patient History & Physical Examination – Evaluating pain patterns, lifestyle habits, and medical history.
- Endoscopy – Visual confirmation of ulcers in the stomach or duodenum.
- Laboratory Tests – Testing for H. pylori infection through blood, breath, or stool analysis.
- Imaging – Barium swallow X-rays can sometimes detect larger ulcers.
These diagnostic steps not only guide treatment but also help determine the most accurate ICD-10 code for peptic ulcer. Treatment for peptic ulcers depends on the specific cause. Treatment modalities include medications such as Proton pump inhibitors (PPI), Histamine receptor blockers (H2 blockers), Antibiotic medications (to kill H. pylori), prescription and over-the-counter medications omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex), esomeprazole (Nexium) and pantoprazole (Protonix).
ICD-10 Coding Guidelines for Gastric and Duodenal Ulcers
The ICD-10 coding guidelines for gastric and duodenal ulcers require coders to select codes based on:
- Ulcer Site – Stomach (gastric), duodenum, or other locations.
- Complication Status – Presence of hemorrhage, perforation, or both.
- Chronicity – Acute, chronic, or unspecified.
- Causative Factors – Such as H. pylori, NSAID use, or post-surgical causes.
Peptic Ulcer Disease Classification in ICD-10
The peptic ulcer disease classification in ICD-10-CM is structured to capture:
- Anatomical location (gastric, duodenal, jejunal, or unspecified)
- Severity and complication type (with hemorrhage, perforation, both, or without complications)
- Stage of disease (acute, chronic, or unspecified)
Diagnosis and treatment must be documented using the right medical codes. The ICD-10 diagnosis codes for peptic ulcer include –
- K27 Peptic ulcer, site unspecified
- K27.0 Acute peptic ulcer, site unspecified, with hemorrhage
- K27.1 Acute peptic ulcer, site unspecified, with perforation
- K27.2 Acute peptic ulcer, site unspecified, with both hemorrhage and perforation
- K27.3 Acute peptic ulcer, site unspecified, without hemorrhage or perforation
- K27.4 Chronic or unspecified peptic ulcer, site unspecified, with hemorrhage
- K27.5 Chronic or unspecified peptic ulcer, site unspecified, with perforation
- K27.6 Chronic or unspecified peptic ulcer, site unspecified, with both hemorrhage and perforation
- K27.7 Chronic peptic ulcer, site unspecified, without hemorrhage or perforation
- K27.9 Peptic ulcer, site unspecified, unspecified as acute or chronic, without hemorrhage or perforation
The specificity in peptic ulcer ICD-10 coding ensures proper reimbursement and accurate health data reporting.
Documentation Requirements for Accurate Peptic Ulcer ICD-10 Coding
Accurate coding begins with comprehensive documentation. Healthcare providers should clearly note:
- Ulcer Location – Stomach, duodenum, or other site.
- Complication Presence – Bleeding, perforation, or obstruction.
- Chronicity – Acute, chronic, or unspecified.
- Underlying Causes – NSAID use, infection, or systemic diseases.
- Diagnostic Evidence – Endoscopy reports, biopsy results, or imaging findings.
Without these details, coders may have to assign less specific codes, which can lead to underpayment or claim denials.
Best Practices for Assigning the Correct ICD-10 Code for Peptic Ulcer
- Review all Clinical Documentation – Ensure it includes ulcer site, type, complications, and chronicity.
- Apply the Most Specific Code Possible – Avoid unspecified codes unless absolutely necessary.
- Stay Updated with ICD-10 Changes – Coding guidelines are updated annually.
- Communicate with Healthcare providers – Clarify ambiguous documentation before coding.
- Leverage Technology – Use EHR-integrated coding tools for accuracy checks.
Accurate peptic ulcer ICD-10 coding is essential for proper reimbursement, quality reporting, and compliance. By understanding peptic ulcer disease classification, following the ICD-10 coding guidelines for gastric and duodenal ulcers, and adhering to documentation requirements for accurate peptic ulcer ICD-10 coding, healthcare providers can avoid common pitfalls. For many healthcare practices, the most efficient solution is to outsource medical billing to experienced professionals, ensuring that every code reflects the patient’s condition and the care provided.
