Hypoparathyroidism, unspecified

This code signifies a condition characterized by insufficient production of parathyroid hormone (PTH), leading to hypocalcemia and hyperphosphatemia. This hormonal imbalance can affect various bodily functions, including bone health, nerve function, and muscle contraction.

Assign this code when the medical record documents a diagnosis of hypoparathyroidism without further specification of its cause (e.g., idiopathic, postsurgical, autoimmune). It is appropriate when the physician has not identified or documented the specific etiology of the parathyroid hormone deficiency.

• Do not use this code if the specific type of hypoparathyroidism is documented; instead, select a more precise code from the E20 category.
• Ensure documentation clearly states "hypoparathyroidism" and lacks further etiological detail to support the "unspecified" designation.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
