The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Brown tumor of hyperparathyroidism
- Calcifying panniculitis due to hyperparathyroidism
- Myopathy in hyperparathyroidism
- Neonatal hyperparathyroidism
- Subcutaneous calcification
- HYPERPARATHYROIDISM-. a condition of abnormally elevated output of parathyroid hormone or pth triggering responses that increase blood calcium. it is characterized by hypercalcemia and bone resorption eventually leading to bone diseases. primary hyperparathyroidism is caused by parathyroid hyperplasia or parathyroid neoplasms. secondary hyperparathyroidism is increased pth secretion in response to hypocalcemia usually caused by chronic kidney diseases.
- HYPERPARATHYROIDISM SECONDARY-. abnormally elevated parathyroid hormone secretion as a response to hypocalcemia. it is caused by chronic kidney failure or other abnormalities in the controls of bone and mineral metabolism leading to various bone diseases such as renal osteodystrophy.
- HYPERPARATHYROIDISM PRIMARY-. a condition of abnormally elevated output of parathyroid hormone due to parathyroid hyperplasia or parathyroid neoplasms. it is characterized by the combination of hypercalcemia phosphaturia elevated renal 125 dihydroxyvitamin d3 synthesis and increased bone resorption.
