Secondary hyperaldosteronism
ICD10CM code
Name of the Condition
- Secondary Hyperaldosteronism
- Also known as renin-mediated hyperaldosteronism.
Summary
Secondary hyperaldosteronism is a condition where there is an overproduction of the hormone aldosterone due to factors outside the adrenal glands, causing issues such as high blood pressure and an imbalance of electrolytes.
Causes
- Excessive anti-diuretic hormone.
- Kidney-related conditions like renal artery stenosis or chronic kidney disease.
- Cardiovascular conditions that reduce blood flow to the kidneys.
- Liver cirrhosis or congestive heart failure.
Risk Factors
- Underlying conditions that affect the heart, liver, or kidneys.
- Genetic predispositions related to adrenal and renal dysfunctions.
- Prolonged hypertension or heart failure.
Symptoms
- High blood pressure (hypertension).
- Low blood potassium levels (hypokalemia).
- Muscle weakness or cramps.
- Fatigue and headache.
- Increased thirst and urination.
Diagnosis
- Blood tests measuring aldosterone and renin levels.
- Electrolyte panel to check potassium levels.
- Imaging studies like CT or MRI for adrenal gland assessment.
- Urinary aldosterone excretion tests.
Treatment Options
- Medications such as spironolactone, which block the effects of aldosterone.
- Treating underlying conditions like renal artery stenosis or heart failure.
- Lifestyle modifications including a low-sodium diet.
- Surgical interventions if a tumor or adrenal gland problem is detected.
Prognosis and Follow-Up
- Good prognosis if underlying causes are effectively managed.
- Regular monitoring of blood pressure, electrolytes, and kidney function.
- Adjustments in treatment plans based on follow-up test results.
Complications
- Chronic hypertension leading to cardiovascular diseases.
- Sustained electrolyte imbalance causing muscle and nerve function issues.
- Kidney damage or failure if untreated.
Lifestyle & Prevention
- Adopt a low-sodium diet to help manage blood pressure.
- Maintain a healthy weight and exercise regularly.
- Manage chronic conditions like hypertension or heart failure proactively.
When to Seek Professional Help
- Sudden increase in blood pressure.
- Signs of low potassium levels like muscle weakness or irregular heartbeats.
- Persistent fatigue or changes in urination patterns.

Tips for Medical Coders
- Ensure differentiation between primary and secondary hyperaldosteronism for accurate coding.
- Check for documentation that specifies the underlying cause or contributing conditions.
- Be vigilant about coding related complications like hypertension or electrolyte imbalances separately.
