Valid for Submission
E20.0 is a billable diagnosis code used to specify a medical diagnosis of idiopathic hypoparathyroidism. The code E20.0 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code E20.0 might also be used to specify conditions or terms like cataract due to idiopathic hypoparathyroidism, idiopathic hypoparathyroidism or idiopathic parathyroidism.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code E20.0 are found in the index:
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
- 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.

Convert E20.0 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code E20.0 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
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.
