Other iatrogenic hypothyroidism

This code signifies hypothyroidism that has been induced by medical intervention, such as surgery, radiation therapy, or medication. It represents a secondary form of thyroid dysfunction resulting directly from a therapeutic or diagnostic procedure.

Use this code when documentation clearly states hypothyroidism developed as a consequence of medical treatment, such as post-thyroidectomy, after radioactive iodine therapy, or due to drug side effects. Ensure the physician explicitly links the hypothyroidism to the iatrogenic cause.

• Differentiate from naturally occurring primary or secondary hypothyroidism; this code specifically requires a medical intervention as the cause.
• Review medication lists and procedure history to confirm the iatrogenic origin.
• Consider an additional E-code to specify the drug or procedure if applicable and documented.
