How To Use CPT Code 93018

CPT 93018 is a code used for the interpretation and report of cardiovascular stress tests; this article will cover its description, procedure, qualifying circumstances, usage, documentation requirements, billing guidelines, historical information, similar codes, and examples.

1. What is CPT 93018?

CPT 93018 is a medical billing code used to represent the interpretation and report of a cardiovascular stress test. This test is performed to analyze and interpret the electrical activity of the heart under stress induced by exercise or medication. The code is specifically used for the professional component of the service, which includes the analysis, interpretation, and report of the test results.

2. 93018 CPT code description

The official description of CPT code 93018 is: “Cardiovascular stress test using maximal or submaximal treadmill or bicycle exercise, continuous electrocardiographic monitoring, and/or pharmacological stress; interpretation and report only.”

3. Procedure

The 93018 procedure involves the following steps:

  1. Patient preparation: The patient is prepared for the stress test, which may involve exercise on a treadmill or bicycle, or the administration of a medication to increase the heart rate.
  2. Continuous monitoring: The patient’s heart is continuously monitored using electrocardiographic (ECG) equipment during the stress test.
  3. Data collection: Blood pressure and ECG readings are collected at regular intervals throughout the test.
  4. Test completion: The stress test is completed once the patient reaches a predetermined level of exertion or experiences symptoms that warrant stopping the test.
  5. Analysis and interpretation: The provider analyzes and interprets the collected data to identify any abnormalities in the heart’s functioning.
  6. Report: The provider completes a detailed report of their findings, which is then used for further evaluation and treatment planning.

4. Qualifying circumstances

Patients who are eligible to receive CPT code 93018 services include those with suspected or known cardiovascular disease, those experiencing symptoms such as chest pain or shortness of breath, and those undergoing preoperative evaluation for non-cardiac surgery. Additionally, patients with risk factors for cardiovascular disease, such as hypertension, diabetes, or a family history of heart disease, may also be eligible for this service.

5. When to use CPT code 93018

It is appropriate to bill the 93018 CPT code when the provider is only responsible for the interpretation and report of the cardiovascular stress test. This code should not be used if the provider is also responsible for the supervision and technical components of the test. In such cases, CPT code 93015 should be used instead. If the provider is only responsible for the technical component, CPT code 93017 should be used.

6. Documentation requirements

To support a claim for CPT 93018, the following information should be documented:

  • Patient’s medical history and reason for the stress test
  • Details of the stress test procedure, including the type of exercise or medication used to induce stress
  • Record of continuous ECG monitoring and blood pressure measurements taken during the test
  • Any symptoms experienced by the patient during the test
  • Provider’s analysis and interpretation of the test results
  • Detailed report of the provider’s findings

7. Billing guidelines

When billing for CPT code 93018, it is important to remember that this code represents the professional component of the service and should not be appended with modifier 26. If the provider is responsible for both the technical and professional components, CPT code 93015 should be used. If the provider is only responsible for the technical component, CPT code 93017 should be used.

8. Historical information

CPT 93018 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.
