Other hyperaldosteronism

This code signifies forms of hyperaldosteronism that are not primary (Conn's syndrome), secondary, or Bartter's syndrome. It represents an excessive production of aldosterone from the adrenal glands due to less common or unspecified etiologies. This leads to electrolyte imbalances, hypertension, and other related symptoms.

Use this code when documentation specifies hyperaldosteronism that doesn't fit the criteria for primary, secondary, or Bartter's syndrome. This includes cases where the specific cause of the elevated aldosterone is identified but falls outside the more common classifications, or when the cause is not yet fully elucidated but hyperaldosteronism is confirmed. Supporting documentation would include laboratory findings of elevated aldosterone and suppressed renin, along with clinical signs of hyperaldosteronism, without a clear primary or secondary cause.

• Do not use this code if the documentation clearly indicates primary hyperaldosteronism (Conn's syndrome) or secondary hyperaldosteronism.
• Ensure the medical record specifies "other" or an unlisted cause of hyperaldosteronism to justify this code.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity impacting treatment.
