This CPT code represents the laboratory analysis of chloride levels in a blood sample.
Modifiers 59, 76, and 91 may be applicable depending on the circumstances of the test. Consult payer guidelines for specific rules.
Medical necessity for a chloride blood test is established when the clinician requires information about the patient's electrolyte balance, particularly chloride levels, to evaluate dehydration, acid-base disorders, kidney function, or other conditions associated with electrolyte imbalances.
The clinical responsibility lies with the laboratory personnel who perform the analysis.The ordering physician is responsible for medical decision-making based on the results.
In simple words: This blood test measures the amount of chloride in your blood. Chloride is a mineral that helps keep your body's fluids balanced. The test can help doctors check for problems with your body's fluids or acids, or with your kidneys or heart.
CPT code 82435 encompasses the analytical procedure for determining the concentration of chloride ions (Cl-) in a blood specimen, typically serum.The test involves the use of chemical reagents and analytical instrumentation to quantify chloride levels, contributing to the assessment of electrolyte balance and various physiological functions. Results are expressed in units of mEq/L or mmol/L.The test is often part of a broader panel of electrolyte tests or comprehensive metabolic panels.
Example 1: A patient presents with symptoms of dehydration, including fatigue and dizziness.The physician orders a basic metabolic panel, including chloride, to evaluate electrolyte imbalances., A patient with a history of heart failure undergoes routine monitoring, which includes an electrolyte panel with serum chloride measurement to assess fluid balance and cardiac function., A patient with severe vomiting and diarrhea is admitted to the hospital. Repeated chloride tests are conducted to monitor fluid and electrolyte status during treatment.
Physician's order specifying the chloride blood test; Properly labeled blood sample with patient identification;Laboratory report detailing the test results and units of measurement;Relevant clinical information in the patient's medical record to support the medical necessity of the test.
