Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Cataract due to idiopathic hypoparathyroidism
  • Idiopathic hypoparathyroidism
  • Idiopathic parathyroidism

Clinical Information

  • HYPOPARATHYROIDISM-. a condition caused by a deficiency of parathyroid hormone or pth. it is characterized by hypocalcemia and hyperphosphatemia. hypocalcemia leads to tetany. the acquired form is due to removal or injuries to the parathyroid glands. the congenital form is due to mutations of genes such as tbx1; see digeorge syndrome; casr encoding calcium sensing receptor; or pth encoding parathyroid hormone.

Diagnostic Related Groups

The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2020 through 09/30/2020.

Information for Patients


Parathyroid Disorders

Most people have four pea-sized glands, called parathyroid glands, on the thyroid gland in the neck. Though their names are similar, the thyroid and parathyroid glands are completely different. The parathyroid glands make parathyroid hormone (PTH), which helps your body keep the right balance of calcium and phosphorous.

If your parathyroid glands make too much or too little hormone, it disrupts this balance. If they secrete extra PTH, you have hyperparathyroidism, and your blood calcium rises. In many cases, a benign tumor on a parathyroid gland makes it overactive. Or, the extra hormones can come from enlarged parathyroid glands. Very rarely, the cause is cancer.

If you do not have enough PTH, you have hypoparathyroidism. Your blood will have too little calcium and too much phosphorous. Causes include injury to the glands, endocrine disorders, or genetic conditions. Treatment is aimed at restoring the balance of calcium and phosphorous.
