Hypokalemia

This code represents a lower-than-normal concentration of potassium in the blood, an electrolyte imbalance that can affect various bodily functions, particularly cardiac and neuromuscular systems. It signifies a serum potassium level below 3.5 mEq/L, which can range from mild to severe.

Use this code when documentation explicitly states a diagnosis of hypokalemia, often identified through laboratory results showing low serum potassium. This can occur in scenarios such as excessive fluid loss (e.g., vomiting, diarrhea), diuretic use, certain endocrine disorders, or inadequate dietary intake.

• Always confirm the diagnosis of hypokalemia with supporting lab values in the medical record.
• Investigate and code any underlying cause of the hypokalemia if documented, as it may be the primary diagnosis.
• Differentiate from other electrolyte imbalances; do not confuse with hyperkalemia or other potassium disorders.
