Hyponatremia ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Hyponatremia? 

Hyponatremia is a condition characterized by low sodium levels in the blood, which can lead to various symptoms ranging from mild to severe. In the medical world, specific codes identify and categorize this condition for diagnosis and billing purposes. These codes, known as ICD-10, are universally recognized and used by healthcare professionals.

Here are some of the most commonly used ICD-10 codes for hyponatremia:

1. E87.1 - Hypo-osmolality and hyponatremia: This code is used for general cases of hyponatremia. It covers conditions with an imbalance in the body's water-to-salt ratio.
2. P74.22 - Neonatal Hyponatremia: This code is used specifically for cases of hyponatremia in newborns. It pertains to issues where the infant's sodium levels are deficient.
3. N25.1 - Secondary Hyperaldosteronism, which includes Bartter Syndrome: This code is used when hyponatremia is caused by the overproduction of aldosterone, a hormone that regulates sodium levels.
4. E22.2 - Syndrome of Inappropriate Secretion of Antidiuretic Hormone: This code is used when hyponatremia results from excessive antidiuretic hormone secretion, leading to fluid retention and diluted sodium levels.
5. E23.2 - Diabetes Insipidus: This code is utilized when hyponatremia is associated with diabetes insipidus, a condition characterized by excessive thirst and urination.
6. R60.0 - Localized Edema: This code is used when hyponatremia leads to localized swelling due to fluid accumulation.

Each of these codes represents a different cause or manifestation of hyponatremia, allowing doctors to diagnose and treat the specific form of the condition accurately.

Which Hyponatremia ICD codes are Billable?

Here's a list of commonly used ICD-10 codes for hyponatremia and whether or not they are billable:

1. E87.1 - Hypo-osmolality and hyponatremia: Yes, this is a billable code. It is used for general cases of hyponatremia.
2. P74.22 - Neonatal Hyponatremia: Yes, this is also a billable code. It is used specifically for cases of hyponatremia that occur in newborns.
3. N25.1 - Secondary Hyperaldosteronism, which includes Bartter Syndrome: Yes, this is a billable code. It is used when hyponatremia is caused by the overproduction of aldosterone, a hormone that regulates sodium levels.
4. E22.2 - Syndrome of Inappropriate Secretion of Antidiuretic Hormone: Yes, this is a billable code. It is used when hyponatremia results from excessive antidiuretic hormone secretion, leading to fluid retention and diluted sodium levels.
5. E23.2 - Diabetes Insipidus: Yes, this is a billable code. It is utilized when hyponatremia is associated with diabetes insipidus, characterized by excessive thirst and urination.
6. R60.0 - Localized Edema: Yes, this is a billable code. It is used when hyponatremia leads to localized swelling due to fluid accumulation.

Remember, a 'billable code' is detailed enough to specify a medical diagnosis for reimbursement purposes.

Clinical Information

Hyponatremia is a medical condition that occurs when your blood has an abnormally low sodium level. Here are some critical clinical points:

• Sodium is an essential electrolyte that helps regulate water balance in and around your cells. It's vital for proper nerve and muscle function.
• Hyponatremia can result from multiple conditions. These include kidney disease, heart failure, and medications that increase urine output.
• Symptoms of hyponatremia can vary greatly. They may include nausea, headache, confusion, seizures, and in severe cases, coma and even death.
• Mild forms of hyponatremia can be asymptomatic but still need medical attention to prevent more severe complications.
• Diagnosing hyponatremia involves blood and urine tests to measure sodium levels. In some cases, it may also require tests to assess the state of your kidneys and thyroid.
• Treatment of hyponatremia depends on the underlying cause. It may involve adjusting medication doses, changing to different drugs, or addressing underlying medical conditions.
• In severe cases, treatment might include intravenous electrolyte solutions and medications to manage symptoms.
• It's crucial to monitor and manage your fluid intake if you have been diagnosed with hyponatremia.
• Preventing hyponatremia involves maintaining a balanced diet with adequate sodium intake, staying hydrated, and managing any chronic conditions that could contribute to electrolyte imbalances.

Synonyms Include

• Sodium Deficiency
• Low Blood Sodium
• Hypo-natremia
• Salt Depletion
• Low Serum Sodium Levels
