    ICD-10-CM Code For Functional Dyspepsia: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K30 includes functional dyspepsia diagnoses covering chronic or recurrent indigestion, postprandial distress, and epigastric pain syndromes without structural disease. These ICD-10-CM diagnosis codes are used to document symptom patterns, severity, and the absence of structural gastrointestinal pathology, capturing clinical complexity relevant to dyspeptic disorders. Accurate coding within the ICD-10-CM K30 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM K30: Functional Dyspepsia Overview

    The diagnoses in this group represent functional dyspepsia, a disorder of the stomach and upper gastrointestinal tract characterized by chronic or recurrent upper abdominal discomfort without an identifiable structural cause. These conditions target the stomach and proximal gastrointestinal motility and sensation. Accurate coding matters for reimbursement because it documents clinical complexity and justifies medical necessity for diagnostic testing and management.

    When to Use

    Use a code from this group when a patient presents with chronic or recurrent upper abdominal symptoms consistent with dyspepsia and diagnostic evaluation has not identified a structural cause. Apply these codes to document symptom-based diagnoses that guide management, monitoring, and claims related to functional upper gastrointestinal disorders.

    Typical Clinical Scenarios

    • A 28-year-old otherwise healthy woman presents to primary care with a 6-month history of postprandial fullness, early satiety, and intermittent upper abdominal discomfort not relieved by antacids. Symptoms are chronic, functional in nature, and have been evaluated with normal basic labs and an unremarkable upper endoscopy; a functional motility disorder is suspected after exclusion of structural disease, so a code from this group is assigned to document the functional dyspeptic syndrome. Typical codes: K30
    • A 55-year-old man comes to the gastroenterology clinic with recurring epigastric pain and bloating associated with meals over the past year, causing reduced oral intake and weight loss; H. pylori testing and endoscopy show no peptic ulcer or mucosal lesions. Because symptoms are persistent, impairing quality of life, and no organic cause is identified, a functional dyspepsia diagnosis is used to classify his chronic disorder. Typical codes: K30
    • A 40-year-old patient presents to the emergency department with acute worsening of long-standing indigestion symptoms, severe epigastric discomfort, and nausea; emergent evaluation excludes acute coronary syndrome and peptic ulcer disease. After urgent workup reveals no structural pathology, the acute exacerbation of a preexisting functional upper gastrointestinal disorder is documented using a code from this group. Typical codes: K30
