12. Jack, a 28-year-old man, has a history of rapid loss of 20-pounds of body weight. Now, he has a complaint of abdominal pain with recurrent rectal bleeding. The CT scan shows a thickened terminal ileum, which is suggestive of Crohn’s disease. To confirm the diagnosis, an endoscopy is performed, which shows normal esophagus and duodenum but multiple erosions in the stomach, along with a few scattered aphthous ulcers in the large intestine and very irregular ileocecal valve. The final diagnosis was made as Crohn’s diagnosis with abscess. What is the appropriate ICD-10 code for this case?
