Also known as
Gastritis and duodenitis
Covers H. pylori infections affecting the stomach and duodenum.
Bacterial agents diseases
Includes H. pylori as a bacterial agent causing disease.
Personal history of other diseases
Can be used to indicate a past H. pylori infection if no longer active.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is H. pylori currently active?
Yes
Do NOT code Z87.710. Code the active infection (e.g., K25.5).
No
Any documented history of H. pylori treatment?
When to use each related code
| Description |

| H. pylori infection |
| H. pylori eradicated |
| Peptic ulcer disease |
Coding lacks specificity (e.g., active vs. past infection). CDI should query for clarification to ensure accurate code assignment.
Diagnosis documented in the clinical notes does not align with coded data, creating compliance and reimbursement risks.
Coding H. pylori without confirmatory diagnostic testing documented. Audit risk for unsubstantiated diagnosis.
Q: What are the most accurate diagnostic tests for confirming H. pylori infection in patients with persistent dyspepsia, considering both invasiveness and cost-effectiveness?
A: When diagnosing H. pylori infection in patients with persistent dyspepsia, clinicians must balance accuracy, invasiveness, and cost-effectiveness. For patients undergoing endoscopy, a rapid urease test or histology from a biopsy is considered the gold standard for diagnosis. These methods offer high sensitivity and specificity. Non-invasive testing options suitable for patients not undergoing endoscopy include the urea breath test (UBT), which is highly accurate in detecting active infection, and stool antigen testing, which offers good sensitivity and specificity. Serology, while widely available, is less useful for confirming active infection due to the persistence of antibodies even after eradication. The choice of test should be guided by patient factors, local availability, and cost considerations. Explore how different diagnostic tests compare in terms of performance characteristics and appropriateness for various clinical scenarios. Consider implementing a testing algorithm that incorporates both invasive and non-invasive options to optimize diagnostic accuracy and resource utilization.
Q: How do I interpret a positive H. pylori stool antigen test result in a patient post-H. pylori eradication therapy, and what further steps should be considered?
A: A positive H. pylori stool antigen test result post-eradication therapy can be challenging to interpret. It may indicate treatment failure, reinfection, or simply the persistence of antigens despite successful bacterial eradication. False positives can also occur, especially if the test is performed too soon after treatment. Current guidelines recommend waiting at least four weeks after completing therapy before performing a test of cure. If a positive result is obtained, clinicians should consider repeating the stool antigen test after a further delay, or opting for a urea breath test for confirmation, which is generally considered more reliable in post-treatment scenarios. Persistent positive results warrant further investigation, including endoscopic evaluation with biopsy for histology and rapid urease testing to definitively assess the presence of active H. pylori infection. Learn more about the potential causes of persistent positive results and the appropriate management strategies.
Patient presents with a history of Helicobacter pylori infection. Past medical history includes documented H. pylori gastritis, confirmed by previous endoscopic biopsy with positive urea breath test or stool antigen test. The patient may report prior treatment for H. pylori eradication therapy, potentially with a documented history of clarithromycin resistance or other antibiotic resistance. Symptoms at the time of initial H. pylori diagnosis may have included dyspepsia, epigastric pain, nausea, bloating, or early satiety. Current symptoms, if any, should be documented. Assess for any history of peptic ulcer disease, gastric cancer, or MALT lymphoma, which are known complications of chronic H. pylori infection. Review current medications, including any proton pump inhibitors, H2 blockers, or other gastrointestinal medications. Plan includes assessment for current H. pylori infection if clinically indicated based on recurring symptoms or other risk factors. Consider retesting with urea breath test, stool antigen test, or endoscopic biopsy if active infection is suspected. Discuss potential need for repeat H. pylori treatment if active infection is confirmed, taking into consideration prior antibiotic regimens and potential resistance patterns. Patient education regarding lifestyle modifications, such as dietary adjustments and smoking cessation, will be provided as appropriate. Follow-up care and monitoring will be scheduled as needed. ICD-10 code Z87.891 (personal history of other specified diseases) or K29.5 (chronic gastritis, unspecified) may be appropriate depending on the clinical context and presenting symptoms. CPT codes for relevant diagnostic tests and procedures should be documented accordingly.
