Postprocedural hypoparathyroidism

This code represents a deficiency of parathyroid hormone that develops as a direct consequence of a medical or surgical procedure. This condition leads to hypocalcemia and can manifest with symptoms such as muscle cramps, paresthesias, and tetany. It is an iatrogenic complication affecting calcium regulation.

Use this code when documentation clearly indicates hypoparathyroidism occurring after an intervention, such as thyroidectomy, parathyroidectomy, or radical neck dissection. The physician's notes should explicitly link the hypoparathyroidism to the preceding procedure. This code is appropriate for both acute and chronic postprocedural hypoparathyroidism.

• Always sequence this code after the code for the underlying complication (e.g., hypocalcemia if present) or as a secondary diagnosis when the primary reason for the encounter is related to managing the hypoparathyroidism.
• Distinguish from other forms of hypoparathyroidism (e.g., autoimmune, idiopathic) which have different code assignments.
• Ensure the operative report or progress notes clearly establish the causal link between the procedure and the onset of hypoparathyroidism.
