The CPT® Code 82693 refers to a laboratory test specifically designed to measure the levels of ethylene glycol in the blood. Ethylene glycol is a colorless, odorless organic compound that is primarily utilized as an antifreeze agent in automotive applications. Due to its toxic nature, even minimal exposure or ingestion of ethylene glycol can lead to severe health complications, including damage to vital organs such as the brain, liver, kidneys, and lungs. The ingestion of ethylene glycol can disrupt normal body chemistry, resulting in a condition known as metabolic acidosis, which can further progress to shock, organ failure, or even death if not promptly addressed. This blood test is crucial in clinical settings when there is a suspicion or confirmation of ethylene glycol poisoning, whether accidental or intentional. To conduct the test, a blood sample is collected through a procedure known as venipuncture, which is reported separately. The analysis of the blood sample is performed using a quantitative enzymatic assay, allowing for precise measurement of ethylene glycol levels in serum or plasma.

The ethylene glycol blood test (CPT® Code 82693) is indicated in specific clinical scenarios where there is a concern for ethylene glycol exposure. The following conditions warrant the performance of this test:
The procedure for conducting the ethylene glycol blood test involves several key steps that ensure accurate measurement of the compound in the blood. The following procedural steps are outlined:
After the blood sample has been collected and processed, the patient may experience minimal discomfort at the venipuncture site, which typically resolves quickly. There are no specific post-procedure care instructions related to the ethylene glycol test itself; however, it is essential for healthcare providers to monitor the patient for any signs of toxicity or complications related to ethylene glycol exposure. The results of the test will guide further clinical management, including potential treatments for poisoning, such as the administration of antidotes or supportive care as needed.

| 90 | Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number. | 91 | Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient. |
