Official Description

Heavy metal (eg, arsenic, barium, beryllium, bismuth, antimony, mercury); qualitative, any number of analytes

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Heavy metals are elements that exhibit metallic properties and are naturally found in the environment. They can be present due to various sources, including environmental pollution from industrial activities, fuel waste, and toxic exposure related to manufacturing processes. While certain heavy metals are essential for human health in trace amounts, excessive accumulation can lead to toxicity and adverse health effects. The CPT® Code 83015 refers to a laboratory test that qualitatively assesses the presence of heavy metals, such as arsenic, barium, beryllium, bismuth, antimony, and mercury, in any number of analytes. This test is particularly relevant in situations where there has been known exposure to heavy metals, such as in occupational settings or during environmental disasters. Additionally, it may be indicated when patients present with symptoms that suggest heavy metal exposure, including anemia, neurological changes, brain dysfunction, kidney or liver damage, or fetal loss. The testing can be conducted on various biological samples, including blood, urine, hair, fingernails, or other body tissues. It is important to note that while CPT® Code 83015 focuses on qualitative analysis, there is a related code, CPT® Code 83018, which is used for quantitative analysis to determine the specific amounts of heavy metals present in a laboratory specimen. The methodology for testing may vary depending on the specific heavy metal being evaluated.

1. Indications

Heavy metal testing using CPT® Code 83015 is indicated in various clinical scenarios where there is a concern for exposure to toxic heavy metals. The following conditions may warrant this testing:

  • Known Exposure: Testing is performed when there has been a documented exposure to heavy metals, particularly in occupational settings or during environmental incidents.
  • Symptoms of Toxicity: The test may be indicated in patients exhibiting symptoms suggestive of heavy metal exposure, such as anemia, neurological changes, brain dysfunction, kidney or liver damage, or fetal loss.

2. Procedure

The procedure for conducting a qualitative heavy metal test under CPT® Code 83015 involves several key steps, which are outlined below:

  • Sample Collection: A biological sample is collected from the patient. This sample may include blood, urine, hair, fingernails, or other body tissues, depending on the clinical context and the specific heavy metals being tested.
  • Laboratory Analysis: The collected sample is sent to a laboratory where it undergoes qualitative analysis to determine the presence of specific heavy metals. The laboratory utilizes various testing methodologies tailored to the specific heavy metals being evaluated.
  • Result Interpretation: Once the analysis is complete, the laboratory provides results indicating whether any of the targeted heavy metals are present in the sample. These results are then interpreted by healthcare professionals in conjunction with the patient's clinical history and symptoms.

3. Post-Procedure

After the heavy metal testing is completed, healthcare providers will review the results with the patient. If heavy metals are detected, further evaluation and management may be necessary, which could include additional testing, treatment for heavy metal toxicity, or referrals to specialists. Patients may also be monitored for any ongoing symptoms or complications related to heavy metal exposure. It is essential for healthcare providers to consider the patient's history and clinical presentation when determining the appropriate follow-up care and interventions.
