Quantitative measurement of carboxyhemoglobin in a blood sample.
Modifiers 90 (reference laboratory) and 91 (repeat test) may be applicable depending on the circumstances.
Medical necessity for this test is established when a patient presents with symptoms suggestive of carbon monoxide poisoning, or has a history of exposure to carbon monoxide-producing sources. The test is crucial to guide appropriate treatment and monitor the patient's response to therapy.
The clinical responsibility lies with the laboratory analyst who performs the quantitative measurement of carboxyhemoglobin in a blood sample using appropriate laboratory techniques and equipment. The ordering physician is responsible for interpreting the results in the context of the patient's clinical presentation.
In simple words: This lab test measures the amount of carbon monoxide attached to your blood's hemoglobin. Carbon monoxide is a poisonous gas that prevents your blood from carrying enough oxygen. This test helps doctors figure out how severe carbon monoxide poisoning is.
This CPT code (82375) represents the quantitative determination of carboxyhemoglobin levels in a blood specimen.Carboxyhemoglobin is a complex formed by the binding of carbon monoxide (CO) to hemoglobin, impairing oxygen transport. The analysis is performed using methods such as spectrophotometry or co-oximetry to measure the amount of carboxyhemoglobin present, expressed as a percentage of total hemoglobin. The results help assess the severity of carbon monoxide poisoning.
Example 1: A patient presents to the emergency department following a house fire with symptoms of headache, dizziness, and nausea.A carboxyhemoglobin level is ordered to assess the severity of carbon monoxide poisoning., A patient is found unconscious in a garage with a running vehicle. Emergency medical services obtain a blood sample for carboxyhemoglobin measurement to confirm carbon monoxide poisoning., A patient reports feeling fatigued and unwell after prolonged exposure to vehicle exhaust fumes in a poorly ventilated area.A carboxyhemoglobin test is used as part of a comprehensive evaluation of potential carbon monoxide exposure.
* Patient demographics and identifying information.* Detailed history of potential carbon monoxide exposure, including duration, source, and environment.* Symptoms experienced by the patient.* Date and time of sample collection.* Laboratory report containing the quantitative carboxyhemoglobin level (%).* Physician's order specifying the test.
** The result is reported as a percentage of total hemoglobin saturated with carbon monoxide.Levels above certain thresholds indicate significant carbon monoxide poisoning, requiring immediate intervention.
