Other postablative hypothyroidism

This code signifies hypothyroidism that develops as a consequence of a medical intervention, specifically the removal or destruction of thyroid tissue. It describes a state of insufficient thyroid hormone production occurring after procedures such as thyroidectomy or radioactive iodine ablation.

Apply this code when documentation clearly states hypothyroidism following a surgical removal of the thyroid gland, radioactive iodine treatment for hyperthyroidism or thyroid cancer, or other ablative procedures. The patient's history should explicitly link the hypothyroidism to a prior intervention that destroyed thyroid tissue.

• Ensure the documentation specifies "postablative" or "postsurgical" to differentiate from other forms of acquired hypothyroidism.
• Do not use for congenital hypothyroidism or hypothyroidism due to autoimmune conditions unless an ablative procedure was also performed.
• Consider sequencing this code after a code for the underlying condition that necessitated the ablative procedure, if still relevant.
