Hyperparathyroidism and other disorders of parathyroid gland
Chapter 4:Endocrine, nutritional and metabolic diseases
ICD-10 E21 is a billable code used to indicate a diagnosis of hyperparathyroidism and other disorders of parathyroid gland.
Hyperparathyroidism is a condition characterized by excessive secretion of parathyroid hormone (PTH) from the parathyroid glands, which are small glands located behind the thyroid gland. This condition leads to elevated levels of calcium in the blood (hypercalcemia), which can result in various symptoms including kidney stones, osteoporosis, and abdominal pain. There are three main types of hyperparathyroidism: primary, secondary, and tertiary. Primary hyperparathyroidism is often caused by a benign tumor on a parathyroid gland (adenoma), while secondary hyperparathyroidism is typically a response to low calcium levels due to chronic kidney disease or vitamin D deficiency. Tertiary hyperparathyroidism occurs when the parathyroid glands become overactive after prolonged secondary hyperparathyroidism. Other disorders of the parathyroid gland may include hypoparathyroidism, which is characterized by insufficient PTH production, leading to low calcium levels and associated symptoms such as muscle cramps and seizures. Accurate diagnosis and management of these conditions require a thorough understanding of the endocrine system and its hormonal interactions.
Detailed lab results, imaging studies, and treatment plans must be documented.
Diagnosis and management of hyperparathyroidism, monitoring of calcium levels, and treatment of related complications.
Endocrinologists must ensure that all relevant hormonal assays are documented to support the diagnosis.
Documentation of renal function tests and calcium-phosphate metabolism is essential.
Management of secondary hyperparathyroidism in patients with chronic kidney disease.
Nephrologists should document the relationship between kidney function and parathyroid hormone levels.
Used to monitor calcium and electrolyte levels in patients with hyperparathyroidism.
Document all lab results and clinical findings.
Endocrinologists should ensure that all relevant tests are ordered and results are interpreted.
Surgical intervention for primary hyperparathyroidism.
Operative reports must detail the procedure and findings.
Surgeons must document indications for surgery and any complications.
Primary hyperparathyroidism is caused by an overproduction of parathyroid hormone due to an adenoma or hyperplasia, while secondary hyperparathyroidism is a compensatory response to low calcium levels, often due to chronic kidney disease or vitamin D deficiency.
Document the patient's symptoms, laboratory results (including calcium and PTH levels), and any imaging studies performed. Specify the type of hyperparathyroidism to ensure accurate coding.
