CPT® Code 82438

Chloride is a negatively charged ion, classified as an electrolyte, which plays a crucial role in maintaining the body's fluid balance and acid-base equilibrium. It interacts with other electrolytes, including potassium, sodium (commonly found in salt), and carbon dioxide (CO2), to regulate various physiological functions. The measurement of chloride levels is essential in clinical settings, as it can provide valuable insights into a patient's health status. Specifically, the test associated with CPT® Code 82438 is utilized to assess chloride concentrations from sources other than urine or blood. This test is particularly significant in the evaluation of conditions such as hypokalemia, a state of low potassium levels in the blood, and renal tubular acidosis, a disorder affecting the kidneys' ability to maintain acid-base balance. By analyzing chloride levels, healthcare providers can better understand underlying health issues and guide appropriate treatment strategies.
