ICD-10: R82.994

Hypercalciuria, denoted by the ICD-10 code R82.994, refers to the presence of an abnormally high concentration of calcium in the urine. This condition can be indicative of various underlying health issues and may lead to complications such as kidney stones or renal impairment if not addressed.

Clinical Description of Hypercalciuria

Definition and Pathophysiology

Hypercalciuria is characterized by elevated levels of calcium in the urine, typically defined as more than 300 mg of calcium excreted in a 24-hour urine collection. The condition can arise from several factors, including:

• Dietary Intake: High calcium intake from food or supplements can lead to increased urinary calcium excretion.
• Metabolic Disorders: Conditions such as hyperparathyroidism, certain malignancies, and vitamin D disorders can cause increased calcium levels in the blood, subsequently leading to hypercalciuria.
• Renal Tubular Dysfunction: Impaired renal tubular reabsorption of calcium can result in excessive calcium loss in urine.

Symptoms and Complications

Many individuals with hypercalciuria may be asymptomatic; however, some may experience symptoms related to kidney stones, such as:

• Severe flank pain
• Hematuria (blood in urine)
• Frequent urination
• Nausea and vomiting

If left untreated, hypercalciuria can lead to the formation of calcium-based kidney stones, which can cause significant pain and may require surgical intervention.

Diagnosis

Diagnosis of hypercalciuria typically involves:

• Urine Tests: A 24-hour urine collection is the standard method to measure calcium levels. A calcium level exceeding 300 mg per day is indicative of hypercalciuria.
• Blood Tests: Serum calcium and parathyroid hormone (PTH) levels are often measured to identify potential underlying causes.
• Imaging Studies: In cases of kidney stones, imaging studies such as ultrasound or CT scans may be performed to assess the kidneys and urinary tract.

Treatment

Management of hypercalciuria focuses on addressing the underlying cause and may include:

• Dietary Modifications: Reducing dietary calcium and sodium intake can help lower urinary calcium levels.
• Medications: Thiazide diuretics may be prescribed to reduce calcium excretion in urine.
• Hydration: Increasing fluid intake can help dilute urine and reduce the risk of stone formation.

Conclusion

ICD-10 code R82.994 for hypercalciuria encapsulates a condition that can have significant implications for renal health. Early diagnosis and appropriate management are crucial to prevent complications such as kidney stones and to address any underlying metabolic disorders. Regular monitoring and lifestyle adjustments can play a vital role in managing this condition effectively.

Hypercalciuria, denoted by the ICD-10 code R82.994, refers to the condition characterized by an excessive amount of calcium in the urine. This condition can lead to various complications, including kidney stones and renal impairment. The management of hypercalciuria typically involves a combination of dietary modifications, pharmacological interventions, and addressing any underlying conditions contributing to the elevated calcium levels. Below is a detailed overview of standard treatment approaches for hypercalciuria.

Dietary Modifications

1. Fluid Intake

Increasing fluid intake is crucial for patients with hypercalciuria. Adequate hydration helps dilute urine and reduces the concentration of calcium, thereby minimizing the risk of stone formation. Patients are often advised to drink at least 2 to 3 liters of water daily, unless contraindicated by other medical conditions.

2. Calcium Intake

While it may seem counterintuitive, dietary calcium should not be excessively restricted. A moderate intake of calcium (around 800-1200 mg per day) is recommended, as low calcium diets can lead to increased intestinal absorption of oxalate, potentially worsening hypercalciuria. Foods rich in calcium include dairy products, leafy greens, and fortified foods.

3. Oxalate and Sodium Reduction

Reducing dietary oxalate (found in foods like spinach, nuts, and chocolate) and sodium can also be beneficial. High sodium intake can increase calcium excretion in urine, so a low-sodium diet is often recommended.

Pharmacological Interventions

1. Thiazide Diuretics

Thiazide diuretics, such as hydrochlorothiazide, are commonly prescribed for patients with hypercalciuria. These medications help reduce urinary calcium excretion by promoting calcium reabsorption in the kidneys. This approach is particularly effective in patients who have a history of calcium stone formation.

2. Potassium Citrate

Potassium citrate can be used to alkalinize the urine, which may help prevent the formation of calcium stones. It also helps to increase urinary citrate levels, which inhibit stone formation.

3. Bisphosphonates

In cases where hypercalciuria is associated with conditions like hyperparathyroidism or malignancy, bisphosphonates may be indicated to lower serum calcium levels.

Addressing Underlying Conditions

1. Hyperparathyroidism

If hypercalciuria is due to primary hyperparathyroidism, surgical intervention to remove the overactive parathyroid gland may be necessary.

2. Malignancy

In cases where hypercalciuria is secondary to malignancy, treating the underlying cancer can help normalize calcium levels.

Monitoring and Follow-Up

Regular follow-up appointments are essential for monitoring calcium levels in urine and serum, as well as assessing kidney function. Patients may undergo periodic imaging studies to check for the presence of kidney stones or other complications.

Conclusion

The management of hypercalciuria (ICD-10 code R82.994) involves a multifaceted approach that includes dietary changes, pharmacological treatments, and addressing any underlying health issues. By implementing these strategies, healthcare providers can help patients effectively manage their condition and reduce the risk of complications such as kidney stones. Regular monitoring and adjustments to the treatment plan are crucial for optimal outcomes.
