ICD-10 Code E34.1 – Other hypersecretion of intestinal hormones (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E34.1 – Other hypersecretion of intestinal hormones
What it is
This code identifies excess production of intestinal hormones from endocrine tissue in the gut. Use it when the record describes hormone oversecretion that is not classified elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect hormone excess, such as recurrent gastrointestinal symptoms or other endocrine effects, but the record should support the specific diagnosis.
When to use this code
Use E34.1 when the clinician documents other hypersecretion of intestinal hormones and does not name a more specific endocrine disorder. It may apply after diagnostic workup identifies intestinal hormone overproduction. Check documentation if the source hormone or syndrome is unclear.
Do not use for
Do not use this code for carcinoid syndrome, hormone deficiency, or nonspecific abdominal complaints without documented hypersecretion. If the condition is better described by another endocrine code, code that diagnosis instead.
Coding tip
Confirm that the provider links symptoms to intestinal hormone hypersecretion before assigning E34.1.
