Understanding Hyperparathyroidism ICD 10: Symptoms, Causes, and Treatments

Before exploring Hyperparathyroidism ICD 10 needs to know what is Hyperparathyroidism in general.

What is Hyperparathyroidism?

Hyperparathyroidism is a medical illness in which the parathyroid glands in the neck create an excessive amount of parathyroid hormone (PTH). This hormone is responsible for controlling calcium and phosphorus levels in the body. Excess PTH production can result in an excess of calcium in the blood, which can cause a number of health problems such as kidney stones, osteoporosis, and digestive disorders.

Research work on Hyperparathyroidism ICD 10:

Hyperparathyroidism is a medical disorder that is coded as E21.0 in the International Classification of Diseases, 10th revision (ICD-10). This number is used to indicate primary hyperparathyroidism, which is caused by a parathyroid gland malfunction. Secondary hyperparathyroidism is classed differently since it is caused by another medical issue, such as kidney disease (E21.2).

What is Hyperparathyroidism ICD 10:

Hyperparathyroidism ICD 10 The International Association of Diseases, 10th Revision (ICD-10) classification code used to describe cases of hyperparathyroidism is ICD 10. ICD 10 is just a coding system that gives different diseases to identify them.

Importance of ICD-10 coding for hyperparathyroidism:

ICD-10 coding for hyperparathyroidism is beneficial for a number of reasons:

Correct diagnosis: If untreated, hyperparathyroidism can have major health repercussions. The use of ICD-10 coding to correctly diagnose and identify a problem allows healthcare practitioners to provide fast and appropriate treatment.

Billing and reimbursement: Healthcare providers bill insurance companies for their services using ICD-10 numbers. Hyperparathyroidism coding must be accurate in order for claims to be processed appropriately and for providers to be compensated for their services.

Public health surveillance: Correct coding of hyperparathyroidism assists public health workers in tracking the disease’s incidence and prevalence. This data is utilized to spot patterns, allocate resources, and create public health policy.

Research: ICD-10 codes are used in studies to find hyperparathyroidism cases and collect data that helps in treatments.

ICD 10 code for hyperparathyroidism:

Hyperparathyroidism is a disorder affecting the parathyroid glands. There are two distinct codes for hyperparathyroidism in the International Classification of Diseases, 10th Edition (ICD-10): E21.0 and E21.2.

E21.0 – Primary hyperparathyroidism ICD 10:

Symptoms of primary hyperparathyroidism are identified using the ICD-10 code E21.0. Primary hyperparathyroidism is caused by a problem with the parathyroid gland, which results in an abundance of PTH production. This causes an increase in calcium levels in the blood, which can cause a number of problems including fatigue, muscle weakness, and kidney stones.

Primary hyperparathyroidism is most commonly caused by a benign tumor on one or more than one of the parathyroid glands. This tumor is characterized as a parathyroid adenoma, and it can cause the gland to produce excess amounts of PTH which creates many health problems.

E21.2 – Secondary hyperparathyroidism ICD 10:

The ICD 10 code for Secondary hyperparathyroidism is E21.2. Secondary hyperparathyroidism is caused by an underlying medical problem, such as kidney disease or a deficiency of vitamin D, which results in a calcium deficit in the blood. This causes the parathyroid glands to have a lot of PTH in an attempt to raise calcium levels.

Secondary hyperparathyroidism can develop gradually and is generally asymptomatic in the beginning. However, it can cause bone loss, fractures, and other issues connected to calcium and bone metabolism over time.

Causes of Hyperparathyroidism ICD 10:

Before treatment of any illness, an individual should know the reason behind the disease. Here are some of the most common causes of hyperparathyroidism:

Primary Hyperparathyroidism Causes:

This condition is caused by a malfunction inside the parathyroid glands, resulting in an overproduction of PTH. A benign tumor (parathyroid adenoma) on one of the parathyroid glands is the most prevalent cause of primary hyperparathyroidism. Additional causes may include parathyroid gland hyperplasia (enlargement) or, in rare cases, parathyroid malignancy.

Secondary Hyperparathyroidism Causes:

Secondary hyperparathyroidism is caused by a medical disease that causes a calcium deficit in the blood. This causes the parathyroid glands to overproduce PTH in an attempt to raise calcium levels which causes many diseases. The following are some of the most common causes of secondary hyperparathyroidism:

Chronic kidney disease: People with kidney disorders are unable to remove excess phosphorus from their bodies, resulting in low calcium levels and excess PTH.

Vitamin D deficiency: A lack of vitamin D is crucial for calcium absorption and metabolism. A vitamin D insufficiency can result in low calcium levels and subsequent PTH overproduction.

Malabsorption syndromes: Some disorders, such as celiac disease, bowel inflammation, or pancreatic insufficiency, can interfere with nutritional absorption, including calcium and vitamin D, resulting in secondary hyperparathyroidism.

Tertiary Hyperparathyroidism:

Tertiary hyperparathyroidism is a condition that can develop in patients who have had secondary hyperparathyroidism for a long time. It is distinguished by the parathyroid glands’ autonomous overproduction of PTH, even after the underlying cause of secondary hyperparathyroidism has been treated.

Symptoms of Hyperparathyroidism ICD 10:

Following are some of the most prevalent symptoms of hyperparathyroidism:

Primary Hyperparathyroidism Symptoms:

Primary Hyperparathyroidism Symptoms include Osteoporosis or osteopenia (bone loss), Kidney stones or urinary tract, infections, abdominal pain, Fatigue and weakness, Depression or anxiety, Muscle weakness or cramps, Loss of appetite or nausea, Constipation, Excessive thirst or urination

Secondary Hyperparathyroidism Symptoms:
Primary Hyperparathyroidism Symptoms include weakness and fatigue, Muscle cramps and spasms, Numbness or tingling in hands, feet, or face, Bone pain or fractures, Loss of appetite or weight loss, Dry, itchy skin, Poor memory or concentration, and increased urination or thirst.

It is important to note that many of these symptoms are non-specific and can occur in other medical disorders.

Diagnosis of Hyperparathyroidism:

Diagnosis of hyperparathyroidism typically involves a combination of:

Medical History and Physical Exam: Your doctor or nurse will normally ask about your symptoms, medical history, and current medications. A physical examination will also be performed to look for symptoms of hyperparathyroidism.

Blood Test: Blood tests also help in diagnosis they can be used to identify calcium, phosphorus, and PTH levels in the blood. Calcium levels are often raised in primary hyperparathyroidism, whereas phosphorus levels are lowered and PTH levels are elevated. Calcium levels may be low, phosphorus levels may be high, and PTH levels may be high in secondary hyperparathyroidism.

Hyperparathyroidism ICD 10

Urine Tests: Urine tests are also helpful in the diagnosis of hyperparathyroidism urine tests can help determine the cause of kidney stones and other diseases.

Imaging Tests: Imaging techniques, such as ultrasound, CT scan, or MRI, can be used to discover tumors or other irregularities in the parathyroid glands.

If hyperparathyroidism has been identified, the root reason for the ailment may require additional testing or imaging. The kind and intensity of hyperparathyroidism will determine the treatment options.

Treatment of Hyperparathyroidism:

Here are some common treatment options for hyperparathyroidism:

Observation and Lifestyle Changes:

If your hyperparathyroidism is mild or asymptomatic, your healthcare provider may advise you to monitor your calcium and PTH levels on a regular basis, as well as make lifestyle changes such as increasing fluid intake, reducing salt and caffeine, and getting regular exercise.


Medications can be used to assist prevent bone loss and lower calcium levels in the blood. Bisphosphonates, calcimimetics, and estrogen replacement therapy are all common drugs.


Surgery may be required to remove any aberrant parathyroid tissue. This is often used to treat original hyperparathyroidism or severe secondary hyperparathyroidism. Under general anesthesia, surgery is frequently performed to remove the afflicted gland through a tiny incision in the neck (s).

Complication Treatment:

If hyperparathyroidism has resulted in problems such as kidney stones, bone loss, or fractures, further treatments may be required to manage these conditions. Medication, dietary changes, or physical therapy may be used.

Working together with your healthcare provider to find the best course of treatment for your specific condition is necessary to maintain your health.


What hyperparathyroidism means?

Hyperparathyroidism is a medical condition in which the parathyroid glands produce too much parathyroid hormone (PTH). The parathyroid glands are small glands located in the neck that regulate calcium and phosphorus levels in the body.

What is the ICD 10 code for secondary hyperparathyroidism?

The ICD-10 code for secondary hyperparathyroidism is E21.2. This code is used to indicate a diagnosis of hyperparathyroidism that is secondary.

What are the 3 types of hyperparathyroidism?

There are three types of hyperparathyroidism:

Primary Hyperparathyroidism, Secondary Hyperparathyroidism, and Tertiary Hyperparathyroidism.


Hyperparathyroidism is, in conclusion, a medical condition. Hyperparathyroidism is classified into three types: primary, secondary, and tertiary. Blood tests, imaging studies, and parathyroid gland biopsies are commonly used to make a diagnosis (s). Treatment options vary depending on the severity of the hyperparathyroidism and the underlying cause, but may include drugs and surgery to remove the afflicted gland (s), Most persons with hyperparathyroidism may manage their symptoms and live healthy, normal lives with the correct diagnosis and therapy.
