ICD-10-CM Code E16.4
Increased secretion of gastrin
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
E16.4 is a billable ICD code used to specify a diagnosis of increased secretion of gastrin. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code E164 is used to code Zollinger-Ellison syndrome
Zollinger–Ellison Syndrome (ZES) is caused by a non–beta islet cell (islet of Langerhans), gastrin-secreting tumor of the pancreas that stimulates the acid-secreting cells of the stomach (parietal cells) to maximal activity, with consequent gastrointestinal mucosal ulceration. ZES may occur sporadically or as part of an autosomal dominant familial syndrome called multiple endocrine neoplasia type 1 (MEN 1). The primary tumor is usually located in the pancreas, duodenum or abdominal lymph nodes, but ectopic locations have also been described (e.g., heart, ovary, gallbladder, liver, kidney).
