Iatrogenic pituitary disorders

This code signifies pituitary dysfunction that is a direct consequence of medical intervention. This can include hypopituitarism or hyperpituitarism resulting from surgery, radiation therapy, or medication. The disorder is not naturally occurring but is an adverse effect of treatment.

Use this code when documentation clearly links a pituitary disorder to a previous medical procedure or treatment. Examples include panhypopituitarism post-transsphenoidal surgery for a pituitary adenoma, or growth hormone deficiency following cranial radiation. The physician's notes must explicitly state the iatrogenic nature of the condition.

• Always sequence the iatrogenic pituitary disorder first, followed by codes for specific manifestations (e.g., secondary adrenal insufficiency, hypothyroidism).
• Ensure documentation specifies the type of pituitary dysfunction (e.g., hypopituitarism, hyperprolactinemia) and the iatrogenic cause.
• Distinguish from naturally occurring pituitary disorders; this code is specifically for treatment-induced conditions.
