Abnormality of secretion of gastrin

This code signifies an abnormal production or release of gastrin, a hormone primarily responsible for stimulating gastric acid secretion. This can manifest as either hypersecretion (excessive gastrin) or hyposecretion (insufficient gastrin), leading to various gastrointestinal disturbances.

Use this code when documentation indicates a diagnosed abnormality in gastrin secretion, such as in cases of Zollinger-Ellison syndrome (gastrinoma) or pernicious anemia. Supporting documentation should include laboratory results confirming elevated or decreased gastrin levels, along with clinical signs and symptoms.

• Differentiate between primary gastrin abnormalities and those secondary to other conditions, as the underlying cause may require an additional code.
• Do not use for general dyspepsia or gastric acid disorders without specific documentation of gastrin secretion abnormality.
• Consider sequencing this code after the definitive diagnosis, such as Zollinger-Ellison syndrome, if applicable.
