Acromegaly and gigantism

This code represents a chronic endocrine disorder characterized by excessive production of growth hormone (GH) by the pituitary gland. In adults, this leads to acromegaly, manifesting as enlargement of hands, feet, and facial features, while in children, it results in gigantism, causing abnormally accelerated growth and height.

Use this code for patients diagnosed with either acromegaly or gigantism due to pituitary overactivity. Documentation should clearly state the diagnosis of acromegaly or gigantism, often supported by elevated IGF-1 levels, abnormal glucose suppression tests, and imaging findings of a pituitary adenoma.

• Differentiate from other causes of excessive growth or large body parts; this code specifically implies pituitary overproduction of GH.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially for management of the condition or its complications.
• Ensure supporting documentation explicitly mentions "acromegaly" or "gigantism" rather than just symptoms like "large hands" or "tall stature."
