Hypopotassemia

This code represents a lower-than-normal concentration of potassium in the blood, an electrolyte imbalance that can affect nerve and muscle function, including the heart. It is often a consequence of various underlying conditions or medication side effects.

Use this code when documentation indicates a serum potassium level below the normal range (typically <3.5 mEq/L). Common scenarios include patients experiencing diuretic therapy, vomiting, diarrhea, or certain endocrine disorders. Supporting documentation should include laboratory results confirming hypokalemia.

• Always look for the underlying cause of hypopotassemia, as it may require additional coding.
• Distinguish from other electrolyte imbalances; this code is specific to potassium deficiency.
• Ensure documentation specifies "hypopotassemia" or "hypokalemia" with supporting lab values.
