E21.2 Other hyperparathyroidism

ICD10CM code

#### Name of the Condition
- Other Hyperparathyroidism (ICD-10 Code: E21.2)
- Hyperparathyroidism, not further classified

#### Summary
Other hyperparathyroidism is a condition characterized by an overactivity of the parathyroid glands which results in an excessive production of parathyroid hormone (PTH). This overproduction can lead to an imbalance of calcium in the body, which can affect various bodily functions.

#### Causes
The causes of other hyperparathyroidism can be varied and may include secondary or tertiary hyperparathyroidism due to chronic kidney disease or vitamin D deficiency. It may also occur after kidney transplant or due to other undiagnosed conditions affecting calcium regulation.

#### Risk Factors
- Chronic kidney disease
- Nutritional deficiencies, such as low vitamin D or calcium intake
- Certain inherited endocrine disorders
- Previous neck surgeries or radiation exposure

#### Symptoms
- Weakness and fatigue
- Bone or joint pain
- Increased urination
- Abdominal pain
- Mental confusion or depression

#### Diagnosis
- Blood tests: Elevated levels of PTH, calcium, and possibly low vitamin D levels
- Imaging tests: Ultrasound or Sestamibi scan to assess the parathyroid glands
- Bone density tests to monitor bone health

#### Treatment Options
- Medications: Cinacalcet to lower PTH levels, vitamin D supplements
- Surgery: Parathyroidectomy to remove overactive glands
- Dialysis or kidney transplant if associated with chronic kidney disease

#### Prognosis and Follow-Up
The prognosis varies depending on underlying causes and treatment effectiveness. Regular monitoring of calcium, PTH levels, and bone health is crucial. Successful management can lead to an improved quality of life.

#### Complications
- Osteoporosis or weakened bones
- Kidney stones
- Cardiovascular issues such as hypertension
- Neurological symptoms including cognitive difficulties

#### Lifestyle & Prevention
- Maintain a balanced diet rich in calcium and vitamin D
- Regular exercise to strengthen bones
- Monitoring and managing chronic conditions like kidney disease

#### When to Seek Professional Help
- Persistent fatigue and bone pain
- Noticeable changes in mood or cognition
- Recurrent episodes of kidney stones

#### Tips for Medical Coders
- Ensure the coding distinguishes between primary, secondary, and other unspecified hyperparathyroidism.
- Check for related conditions, such as renal disorders or nutritional deficiencies, that may impact coding.
- Avoid confusing secondary or tertiary hyperparathyroidism with primary hyperparathyroidism.
