    ICD-10-CM Code For Gastric Ulcer: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K25 includes gastric ulcer diagnoses, covering acute and chronic gastric ulcers with or without hemorrhage and perforation. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving stomach mucosal injury, complications such as bleeding or perforation, and severity distinctions that affect care. Accurate coding within the ICD-10-CM K25 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    When to Use

    Use a code from this group when a documented diagnosis specifies a gastric ulcer and notes the presence or absence of hemorrhage or perforation. Select the code that reflects the ulcer chronicity and any complications documented in the clinical record.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset severe epigastric pain, hematemesis, and melena after several days of NSAID use; vital signs show tachycardia and hypotension suggesting acute blood loss. Endoscopy reveals a bleeding gastric ulcer with active hemorrhage, and the clinician documents an acute, bleeding gastric ulcer as the principal diagnosis, so an acute, hemorrhagic code from this group is assigned. Typical codes: K25.0, K25.2
    • A middle-aged patient with a long history of peptic ulcer disease and intermittent epigastric discomfort arrives for routine follow-up because of persistent dyspepsia despite therapy; testing shows a nonhealing chronic gastric ulcer without current bleeding. The encounter is for management of an ongoing, chronic gastric ulcer, and a chronic, nonhemorrhagic code from this group is recorded. Typical codes: K25.1, K25.4
    • An elderly hospitalized patient with known gastric ulcer disease develops perforation and generalized peritonitis after several days of worsening abdominal pain and rigidity; imaging confirms a perforated gastric ulcer requiring surgical intervention. Because the ulcer has resulted in a complication (perforation), a code indicating a gastric ulcer with perforation from this group is assigned for the inpatient stay. Typical codes: K25.3, K25.6
