ICD Code E21-

ICD code E21- is hyperparathyroidism, which refers to an overactivity of the parathyroid glands resulting in excessive production of parathyroid hormone.

1. Presence of hypercalcemia confirmed by laboratory testing

2. Elevated or inappropriately normal parathyroid hormone (PTH) levels

3. Evidence of parathyroid gland abnormality (e.g., adenoma, hyperplasia) via imaging or surgical findings

4. Symptoms such as bone pain, kidney stones, abdominal pain, psychiatric disturbances, or muscle weakness

5. Exclusion of other causes of hypercalcemia (e.g., malignancy, medication-induced)

6. Chronic or recurrent nature of the condition

7. Family history suggestive of hereditary parathyroid disorders (if applicable)
