Other specified disorders of pancreatic internal secretion

This code represents endocrine dysfunctions of the pancreas that do not fit into more specific categories of diabetes mellitus, hypoglycemia, or cystic fibrosis-related pancreatic disorders. It encompasses conditions where the pancreas produces hormones other than insulin or glucagon abnormally, or where insulin/glucagon secretion is dysfunctional but not meeting criteria for other specified codes.

Use this code for documented pancreatic endocrine disorders such as somatostatinoma, VIPoma, or other rare pancreatic neuroendocrine tumors that primarily affect hormone secretion. It is also appropriate for cases of non-diabetic, non-hypoglycemic pancreatic endocrine dysfunction where a more specific ICD-10-CM code is unavailable. Documentation should clearly specify the pancreatic endocrine abnormality.

• Do not use this code for diabetes mellitus or hypoglycemia; those have specific codes.
• Ensure documentation specifies "other specified" pancreatic internal secretion disorder, not just a general pancreatic issue.
• Consider sequencing this code after a code for the underlying tumor or condition if applicable.
