Official Description

Buprenorphine

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 80348 refers to a laboratory test specifically designed to measure the levels of buprenorphine and its metabolites in biological samples such as urine, serum, or plasma. Buprenorphine is classified as a semi-synthetic opioid partial agonist, which means it activates opioid receptors in the brain but to a lesser degree than full agonists. This property makes it particularly useful in the treatment of opioid addiction, as it can help manage withdrawal symptoms and cravings without producing the same level of euphoria associated with stronger opioids. Additionally, buprenorphine is utilized for controlling acute or chronic pain in individuals who are not tolerant to opioids. The medication is available in various formulations, including oral tablets (such as Subutex, Suboxone, and Zubsolv) for the treatment of opioid dependence, and sublingual preparations (like Temgesic) for managing moderate to severe pain. For acute pain management, buprenorphine can be administered via injection (Buprenex), while chronic pain may be treated with transdermal patches (Norspan, Butrans) that deliver the drug through the skin over an extended period. To perform the test, a blood sample is typically obtained through venipuncture, which is a separately reportable procedure. Urine samples can be collected either by random voiding or through catheterization. The testing process involves advanced techniques such as quantitative high-performance liquid chromatography-tandem mass spectrometry for serum or plasma samples, and quantitative liquid chromatography-tandem mass spectrometry for urine samples. These methods ensure accurate measurement of buprenorphine levels, which is essential for monitoring treatment efficacy and compliance in patients undergoing therapy for opioid addiction or pain management.

1. Indications

The laboratory test associated with CPT® Code 80348 is indicated for the following conditions:

  • Opioid Addiction Treatment This test is performed to monitor patients undergoing treatment for opioid addiction with buprenorphine, ensuring adherence to the prescribed therapy.
  • Pain Management It is utilized to assess the levels of buprenorphine in patients receiving the drug for the management of acute or chronic pain, particularly in those who are not opioid-tolerant.

2. Procedure

The procedure for conducting the buprenorphine test involves several key steps, which are detailed as follows:

  • 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. This process is typically performed by a trained healthcare professional. For urine testing, samples can be collected either by random voiding, where the patient provides a urine sample at any time, or through catheterization, which involves inserting a catheter into the bladder to obtain urine directly.
  • Step 2: Sample Preparation Once the samples are collected, they must be prepared for analysis. This preparation may involve centrifugation of the blood samples to separate the serum or plasma from the cellular components. The urine samples may also require specific handling to ensure accurate testing results.
  • Step 3: Analytical Testing The prepared samples are then subjected to quantitative analysis using advanced laboratory techniques. For serum or plasma, quantitative high-performance liquid chromatography-tandem mass spectrometry is employed, which allows for precise measurement of buprenorphine and its metabolites. For urine samples, quantitative liquid chromatography-tandem mass spectrometry is utilized, providing similar accuracy in detecting the presence and concentration of buprenorphine.

3. Post-Procedure

After the completion of the buprenorphine testing procedure, the samples are analyzed, and the results are typically available within a specified timeframe, depending on the laboratory's processing capabilities. Healthcare providers will review the test results to determine the appropriate course of action for the patient, which may include adjustments to the treatment plan based on the buprenorphine levels detected. It is essential for healthcare professionals to communicate the results to the patient and discuss any necessary follow-up actions or additional testing that may be required. Proper documentation of the test results and any subsequent decisions made is crucial for maintaining compliance and ensuring continuity of care.

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.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
