Official Description

Alcohol (ethanol); any specimen except breath

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82055 refers to the laboratory testing of alcohol (ethanol) levels in any specimen type, excluding breath samples. Ethanol is classified as a central nervous system depressant, and measuring its levels is crucial for documenting prior consumption or administration of the substance. This code specifically encompasses tests performed on blood or urine samples to determine the concentration of alcohol present. For blood testing, a sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the blood sample is typically conducted using advanced techniques such as gas liquid chromatography or enzymatic methods. In the case of urine testing, the samples are evaluated using either alcohol dehydrogenase or gas chromatography-flame ionization detection methods. It is important to note that this code does not include breath tests, which are covered under CPT® Code 82075. Breath tests measure the levels of alcohol exhaled in the breath, correlating the concentration of alcohol in the alveoli air to blood alcohol content (BAC) through various methods, including chemical analysis, infrared spectroscopy, or fuel cell technology. Overall, CPT® Code 82055 is essential for accurately assessing alcohol levels in patients, aiding in clinical decision-making and legal considerations.

1. Indications

The procedure associated with CPT® Code 82055 is indicated for various clinical scenarios where the measurement of alcohol (ethanol) levels is necessary. These indications include:

  • Assessment of Alcohol Intoxication This test is performed to evaluate a patient's level of intoxication, particularly in emergency situations or when a patient presents with altered mental status.
  • Monitoring Alcohol Consumption It is used to monitor individuals with a history of alcohol use disorder or those undergoing treatment for alcohol dependence.
  • Legal and Forensic Testing The test may be required in legal cases, such as driving under the influence (DUI) incidents, to provide evidence of blood alcohol concentration.
  • Preoperative Assessment It can be part of preoperative evaluations to ensure patient safety, especially in individuals with a history of alcohol use.

2. Procedure

The procedure for CPT® Code 82055 involves several key steps to ensure accurate measurement of alcohol levels in the specified specimens. The following procedural steps are outlined:

  • Step 1: Sample Collection A blood sample is obtained through a process known as venipuncture, where a needle is inserted into a vein to draw blood. This step is critical as it ensures that the sample is collected in a sterile manner to prevent contamination and ensure the integrity of the test results.
  • Step 2: Sample Preparation Once the blood sample is collected, it may be processed to separate the serum or plasma, depending on the testing requirements. For urine samples, a clean catch or random urine sample may be collected, ensuring that the specimen is suitable for testing.
  • Step 3: Analytical Testing The collected blood or urine samples are then analyzed using specific techniques. Blood samples are typically examined using gas liquid chromatography or enzymatic methods, which provide precise measurements of ethanol concentration. For urine samples, testing may involve alcohol dehydrogenase or gas chromatography-flame ionization detection methods, which are effective in quantifying alcohol levels.

3. Post-Procedure

After the procedure associated with CPT® Code 82055, the following post-procedure considerations are important. Patients may be monitored for any adverse reactions, especially if the test was performed in an emergency setting. The results of the alcohol level test are typically available within a short timeframe, allowing for timely clinical decision-making. It is essential for healthcare providers to interpret the results in conjunction with the patient's clinical presentation and history. Additionally, documentation of the test results and the circumstances surrounding the testing is crucial for legal and medical records. Follow-up care may be necessary for patients with elevated alcohol levels, particularly if they are at risk for alcohol-related complications or require intervention for alcohol use disorder.
