CPT® Code 83050

Methemoglobin is a form of hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body. In methemoglobin, the iron within the heme group is oxidized to the ferric state, which prevents it from effectively releasing oxygen to tissues. Normally, about 1-2% of hemoglobin in the human body exists as methemoglobin; however, elevated levels can occur due to genetic factors or more commonly, as a result of exposure to certain drugs or environmental toxins. The measurement of methemoglobin levels is crucial in diagnosing conditions related to oxygen transport and can help identify potential toxic exposures. To obtain a sample for this test, a venipuncture is performed, which is a separate procedure that must be reported accordingly. It is important to distinguish between the tests for the presence of methemoglobin and the quantitative measurement of its levels, as different CPT® codes are used for each. Specifically, CPT® Code 83050 is utilized when quantifying the amount of methemoglobin in the blood.
