Hyperaldosteronism (E26)
Hyperaldosteronism ICD-10 code E26 identifies conditions related to excess production of aldosterone, a hormone controlling sodium and potassium balance. This section covers various types and causes, from primary forms like Conn’s syndrome to secondary and other hyperaldosteronism diagnoses.
The code E26 and its subcategories are used to classify different causes and presentations of hyperaldosteronism accurately. For example, E26.01 denotes Conn's syndrome, also known as primary hyperaldosteronism due to adrenal adenoma or aldosterone-producing adenoma. Coders can also assign E26.02 for glucocorticoid-remediable aldosteronism, which includes familial types. Other primary hyperaldosteronism types such as idiopathic or hyperplasia-related forms fall under E26.09. Secondary hyperaldosteronism, often linked to conditions like juxtaglomerular hyperplasia, is captured by E26.1. Additionally, E26.81 codes for Bartter’s syndrome, a genetic disorder presenting as hypokalemic and hypochloremic alkalosis. The unspecified hyperaldosteronism uses E26.9, covering cases without a defined cause. These distinctions help healthcare providers and coders document the specific pathology in patients with elevated aldosterone levels.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Bartter Syndrome
A group of disorders caused by defective salt reabsorption in the ascending LOOP OF HENLE. It is characterized by severe salt-wasting, HYPOKALEMIA; HYPERCALCIURIA; metabolic ALKALOSIS, and hyper-reninemic HYPERALDOSTERONISM without HYPERTENSION. There are several subtypes including ones due to mutations in the renal specific SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.
Hyperaldosteronism
A condition caused by the overproduction of ALDOSTERONE. It is characterized by sodium retention and potassium excretion with resultant HYPERTENSION and HYPOKALEMIA.
