Official Description

Oxycodone

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A laboratory test identified by CPT® Code 80365 is specifically designed to measure the presence and concentration of oxycodone, a semi-synthetic opioid, in biological samples such as urine, serum, or plasma. Oxycodone is classified as a narcotic analgesic and is commonly utilized in the management of moderate to severe acute or chronic pain. This medication can be administered independently or in conjunction with other analgesics, such as aspirin or acetaminophen, to enhance pain relief. The administration of oxycodone can occur through various routes, including oral ingestion or injection. To perform this test, a blood sample is typically collected via venipuncture, which is a separate procedure that must be reported independently. Alternatively, urine samples can be obtained through random voiding or catheterization. The testing process involves screening urine samples using a qualitative enzyme immunoassay, while urine, serum, and plasma samples are analyzed quantitatively using liquid chromatography-tandem mass spectrometry, a highly sensitive and specific method for detecting and quantifying substances in biological fluids.

1. Indications

The oxycodone laboratory test (CPT® Code 80365) is indicated for the following conditions:

  • Monitoring Pain Management: This test is performed to assess the levels of oxycodone in patients who are undergoing treatment for moderate to severe acute or chronic pain, ensuring that the medication is being administered effectively.
  • Substance Abuse Evaluation: The test may be utilized in the evaluation of potential substance abuse or misuse of oxycodone, helping healthcare providers to identify patients who may be at risk.
  • Compliance Verification: It is used to verify patient compliance with prescribed oxycodone therapy, ensuring that patients are taking the medication as directed.

2. Procedure

The procedure for conducting the oxycodone test involves several key steps, which are detailed below:

  • Step 1: Sample Collection The first step in the procedure is the collection of biological samples. For serum or plasma testing, a blood sample is obtained through venipuncture, which involves inserting a needle into a vein to draw blood. For urine testing, a sample can be collected either through random voiding, where the patient provides a urine sample at any time, or through catheterization, which involves inserting a catheter into the bladder to collect urine directly.
  • Step 2: Sample Screening Once the samples are collected, the urine sample undergoes initial screening using a qualitative enzyme immunoassay. This screening method is designed to detect the presence of oxycodone in the urine, providing a preliminary assessment of drug levels.
  • Step 3: Quantitative Analysis Following the screening, urine, serum, and plasma samples are subjected to quantitative analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS). This advanced testing method allows for precise measurement of oxycodone concentrations in the samples, providing detailed information about the drug levels present in the patient's system.

3. Post-Procedure

After the completion of the oxycodone testing procedure, the samples are analyzed, and results are typically available within a specified timeframe, depending on the laboratory's processing capabilities. Patients may not require any specific post-procedure care, as the sample collection methods are minimally invasive. However, healthcare providers should ensure that patients are informed about the test results and any necessary follow-up actions based on the findings. It is also important to document the results accurately in the patient's medical record for ongoing monitoring and treatment planning.

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.
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
