Hyperpotassemia

This code signifies an abnormally high concentration of potassium in the blood, exceeding the normal physiological range. Hyperkalemia can lead to serious cardiac arrhythmias and neuromuscular dysfunction if left untreated. It often indicates an underlying medical condition affecting potassium regulation.

Use this code when documentation explicitly states hyperkalemia or elevated serum potassium levels. This typically occurs in patients with renal failure, metabolic acidosis, or those on certain medications like ACE inhibitors or potassium-sparing diuretics. Lab results confirming high potassium are essential for accurate coding.

• Always review lab results and physician documentation for the specific potassium level and any associated symptoms or underlying causes.
• Distinguish from hypokalemia (low potassium), which has a different code.
• Consider sequencing this code as a secondary diagnosis if the hyperkalemia is a complication of another primary condition, such as chronic kidney disease.
