Final answer:
To code a disorder of the hypersecretion of intestinal hormones, the coder should reference the term hypersecretion in the alphabetic index.
Step-by-step explanation:
The term hypersecretion should be referenced in the alphabetic index to code a disorder of the hypersecretion of intestinal hormones. Hypersecretion is defined as the secretion of more than the normal amount of a substance, such as secretion of too much hormone by an endocrine gland. In this case, the disorder involves the hypersecretion of intestinal hormones, so the coder should reference the term hypersecretion in the alphabetic index.
