Official Description

Ethchlorvynol

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82690 refers to a laboratory test that measures the therapeutic levels of ethchlorvynol, a sedative and hypnotic medication commonly known by its brand name, Placidyl. Ethchlorvynol is classified as a tertiary carbinol and is typically prescribed for short-term management of insomnia. The testing can be performed using either a blood sample or a urine sample. For blood testing, a venipuncture is required, which is a procedure where a needle is inserted into a vein to collect blood. Alternatively, a urine sample can be collected through random voiding, which involves the patient urinating into a container without any specific preparation. The analysis of the samples is conducted using gas chromatography, a technique that separates and analyzes compounds in the samples to determine the concentration of ethchlorvynol present. This test is crucial for monitoring the levels of the medication in the body to ensure they remain within therapeutic ranges, thereby optimizing treatment efficacy and minimizing potential side effects.

1. Indications

The procedure associated with CPT® Code 82690 is indicated for the following conditions:

  • Monitoring Therapeutic Levels The test is performed to monitor the therapeutic levels of ethchlorvynol in patients who are prescribed this medication for insomnia.
  • Assessing Medication Compliance It helps in assessing whether patients are adhering to their prescribed dosage of ethchlorvynol.
  • Evaluating Potential Toxicity The test is also indicated for evaluating potential toxicity or adverse effects associated with ethchlorvynol use.

2. Procedure

The procedure for obtaining the necessary samples for testing ethchlorvynol levels involves specific steps that ensure accurate results.

  • Step 1: Sample Collection The first step in the procedure is the collection of either a blood or urine sample. For blood testing, a healthcare professional performs a venipuncture, which involves inserting a needle into a vein, typically in the arm, to draw a blood sample. This process is done using sterile techniques to prevent contamination and ensure patient safety. Alternatively, a urine sample can be collected through random voiding, where the patient is instructed to urinate into a sterile container without any prior preparation. This method is less invasive and can be performed quickly in a clinical setting.
  • Step 2: Sample Processing Once the samples are collected, they are processed for analysis. Blood samples may be separated into serum or plasma, depending on the laboratory's protocols. The urine sample is also prepared for testing. Both types of samples are then subjected to gas chromatography, a sophisticated analytical technique that separates the components of the samples based on their chemical properties. This method allows for precise measurement of ethchlorvynol levels in the samples.

3. Post-Procedure

After the procedure, the collected samples are sent to the laboratory for analysis. Patients may be advised to wait for the results, which typically take a few days, depending on the laboratory's processing time. It is important for healthcare providers to review the results to determine if the ethchlorvynol levels are within the therapeutic range. If levels are found to be too high, adjustments to the medication dosage may be necessary to prevent potential toxicity. Patients should also be monitored for any side effects or adverse reactions related to ethchlorvynol use during the treatment period.
