ICD10 code of Nephrogenic diabetes insipidus and ICD9 code

The ICD-10 code for nephrogenic diabetes insipidus is N25.1, while the corresponding ICD-9 code is 588.1. These medical billing codes are used by healthcare providers and insurance companies to classify this specific condition, which is characterized by the kidneys' inability to respond to antidiuretic hormone.

What is the clinical nature of nephrogenic diabetes insipidus?

Nephrogenic diabetes insipidus is a rare disorder where the kidneys fail to concentrate urine despite adequate levels of vasopressin (antidiuretic hormone). Unlike central diabetes insipidus, which stems from a lack of hormone production in the brain, nephrogenic diabetes insipidus results from a defect in the kidney's ability to respond to that hormone. This leads to the hallmark symptoms of polyuria (excessive urination) and polydipsia (extreme thirst). At DiseaseMaps.org, we currently support a community of 66 people with nephrogenic diabetes insipidus, who share insights on managing the daily challenges of fluid balance and electrolyte regulation.

How is nephrogenic diabetes insipidus diagnosed and coded?

Diagnosis typically involves a water deprivation test followed by the administration of synthetic vasopressin (desmopressin). If the urine fails to concentrate after desmopressin is administered, it confirms a diagnosis of nephrogenic diabetes insipidus. When documenting this in electronic health records, clinicians use the ICD-10 code N25.1 (Nephrogenic diabetes insipidus) to ensure accurate billing and clinical tracking. Historically, the ICD-9 code 588.1 was utilized for this purpose before the transition to the updated classification system.

Is nephrogenic diabetes insipidus hereditary?

The condition can be either congenital or acquired. Congenital nephrogenic diabetes insipidus is most commonly caused by an X-linked recessive mutation in the AVPR2 gene, which encodes the vasopressin V2 receptor. Less frequently, it is caused by autosomal recessive or dominant mutations in the AQP2 gene. Because the X-linked form is the most prevalent, the disease predominantly affects males, though female carriers may sometimes show mild symptoms. Understanding the specific genetic cause is a vital step for families seeking genetic counseling.

What are the primary management strategies for patients?

Management of nephrogenic diabetes insipidus focuses on maintaining hydration and reducing urine volume. Clinical experts recommend the following approaches:

• Dietary Modification: Reducing salt and protein intake to lower the solute load the kidneys must excrete.


• Pharmacological Support: The use of thiazide diuretics and non-steroidal anti-inflammatory drugs (NSAIDs) to paradoxically reduce urine volume.


• Fluid Monitoring: Constant access to water to prevent life-threatening dehydration and hypernatremia.


• Regular Laboratory Testing: Periodic monitoring of serum sodium, potassium, and renal function to avoid complications.

Next steps

• Consult a nephrologist or an endocrinologist to discuss current treatment protocols and long-term renal health.


• Speak with a clinical geneticist if you have a family history of nephrogenic diabetes insipidus to understand your risk and inheritance patterns.


• Connect with the 66 members of the DiseaseMaps.org community to share experiences and coping strategies for living with this condition.


• Keep a daily fluid intake and output log to help your medical team adjust your treatment plan effectively.
