E21.0
Primary hyperparathyroidism
Clinical Classification Guidelines
Inclusion Terms
- Hyperplasia of parathyroid
- Osteitis fibrosa cystica generalisata [von Recklinghausen's disease of bone]
Medical Intelligence & Overview
Primary hyperparathyroidism is a condition where the parathyroid glands produce too much hormone, leading to elevated calcium levels in the blood. This disorder primarily results from overgrowth (hyperplasia) of the parathyroid glands or, less commonly, from tumors. The excess hormone disrupts calcium and phosphate balance, affecting various bodily functions and potentially causing bone health issues and other complications.
Causes & Symptoms
Clinical Causes: Parathyroid gland hyperplasia (overgrowth of all glands) Parathyroid adenoma (benign tumor in one gland) Parathyroid carcinoma (rare malignant tumor) Genetic syndromes associated with hyperparathyroidism Chronic kidney disease (secondary hyperparathyroidism may develop into primary forms, but this is distinct)
Key Symptoms: Bone pain and fragility Muscle weakness Fatigue and general malaise Kidney stones Abdominal pain Nausea and vomiting Constipation Increased thirst and urination Depression or cognitive disturbances Elevated blood calcium levels (hypercalcemia)
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of blood tests and imaging studies: - Blood tests showing elevated calcium levels and parathyroid hormone (PTH) concentrations. - Urinalysis detecting increased calcium excretion. - Imaging procedures like ultrasound, sestamibi scans, or MRI to identify enlarged parathyroid glands or tumors. - Bone density scans to assess for osteoporosis or other bone-related changes. These assessments help confirm the presence of hyperparathyroidism and identify its cause.
Treatment Protocols: Treatment options depend on the severity of the condition and underlying cause: - Surgical removal of overactive parathyroid glands is the most common and effective treatment, especially in symptomatic cases. - Monitoring and managing mild cases without symptoms, including regular blood tests and lifestyle modifications. - Managing complications such as osteoporosis with medications or lifestyle adjustments. - Addressing any associated kidney stones or other related conditions. In some cases, medication might be used to control calcium levels, but surgery is often the definitive therapy.

Yes, E21.0 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report E21.0?
Clinical documentation must specify the nature of Primary hyperparathyroidism and any associated comorbidities for accurate reporting.
