Other hyperparathyroidism
ICD-10 E21.2 is a billable code used to indicate a diagnosis of other hyperparathyroidism.
Other hyperparathyroidism refers to conditions characterized by excessive secretion of parathyroid hormone (PTH) from the parathyroid glands, leading to elevated serum calcium levels. This condition can arise from various etiologies, including parathyroid adenomas, hyperplasia, or malignancies. Unlike primary hyperparathyroidism, which is often due to a solitary adenoma, other hyperparathyroidism may be secondary to chronic kidney disease or tertiary hyperparathyroidism, where the parathyroid glands become hyperplastic due to prolonged stimulation. Symptoms may include bone pain, kidney stones, fatigue, and gastrointestinal disturbances. Diagnosis typically involves serum calcium and PTH level measurements, alongside imaging studies to assess for parathyroid abnormalities. Management may involve surgical intervention, particularly in cases of adenomas, or medical management in secondary cases, focusing on the underlying cause of the hyperparathyroidism.
Thorough documentation of hormone levels, imaging studies, and treatment plans.
Patients presenting with hypercalcemia, bone pain, or kidney stones.
Endocrinologists must ensure that all relevant lab results and imaging studies are included in the documentation to support the diagnosis.
Detailed records of kidney function tests and management of secondary causes.
Patients with chronic kidney disease presenting with elevated PTH levels.
Nephrologists should document the relationship between kidney function and parathyroid hormone levels to justify the diagnosis.
Used in cases of parathyroid adenoma leading to hyperparathyroidism.
Operative reports must detail the procedure and findings.
Endocrinologists must ensure that the surgical necessity is well-documented.
Primary hyperparathyroidism is typically caused by a solitary adenoma, while other hyperparathyroidism can result from various conditions, including chronic kidney disease or parathyroid hyperplasia.
