Postsurgical hypoinsulinemia

This code represents a deficiency in insulin production that develops as a direct consequence of a surgical intervention. It indicates a state of insufficient insulin secretion following surgery, often leading to hyperglycemia. This condition is distinct from pre-existing diabetes or other forms of hypoinsulinemia.

Use this code when documentation clearly links a patient's hypoinsulinemia to a prior surgical procedure, particularly pancreatectomy or other surgeries affecting the pancreas. Supporting documentation should include a history of surgery, laboratory findings confirming low insulin levels, and clinical signs of insulin deficiency.

• Do not use for pre-existing diabetes mellitus or other forms of secondary diabetes not directly caused by surgery.
• Always sequence this code after the code for the underlying surgical complication or the primary reason for the patient's encounter, if applicable.
• Ensure documentation specifies the surgical procedure that led to the hypoinsulinemia.
