Answer: B
K25.3 is the appropriate code here because it codes for acute gastric ulcer without hemorrhage or perforation. Here, the patient is diagnosed with acute gastric ulcer. Also, no signs of hemorrhage are found and perforation is not mentioned.
Option A is not correct because K26.0 indicates acute duodenal ulcer without hemorrhage or perforation. Here, the ulceration is gastric.
Option C is not correct because R10.9 codes for unspecified abdominal pain. Here, pain is secondary to gastric ulcer.
Option D is not correct because K70.0 is used to code for alcoholic fatty liver.
