Reader Question:

80051 Isn't Quite Right for This Case

Question:  A physician orders blood electrolytes potassium, sodium, calcium, chloride, magnesium, and phosphate for a patient. Should we code one of the panels that includes many of these elements for performing the test?

Answer: No, you should not report one of the organ and disease-oriented panel codes from 80047-80076 for performing these tests. None of the CPT® listed panels contain the precise blood tests requested by the physician in your case. For instance, 80051 (Electrolyte panel; This panel must include the following: Carbon dioxide [bicarbonate] [82374]; Chloride [82435]; Potassium [84132]; Sodium [84295]) includes chloride, potassium, and sodium, but it also includes carbon dioxide, which the physician didn’t order.

Regarding the panels, CPT® states, “These panels were developed for coding purposes only and should not be interpreted as clinical parameters.” If the ordering physician requests a group of tests not identified by a panel code, based on the patient’s specific clinical condition, you should code each ordered test.

For this case, use the following codes:

·         84132, Potassium; serum, plasma or whole blood

·         84295, Sodium; serum, plasma or whole blood

·         82310, Calcium; total

·         82435, Chloride; blood

·         83735, Magnesium

·         84100, Phosphorus inorganic (phosphate).
