The ergonovine provocation test, identified by CPT® Code 93024, is a diagnostic procedure utilized to assess the cause of chest pain in patients who have no signs of atherosclerotic coronary artery disease or other coronary abnormalities as determined by arteriography. This test is particularly valuable in distinguishing between chest pain resulting from coronary artery spasm and that associated with esophageal spasm. During the procedure, ergonovine, which is also known as ergometrine or Methergine, is administered intravenously to the patient in a controlled manner. The administration begins with an initial dose of 0.1 mg, followed by incremental doses every five minutes until the patient reports chest pain. Throughout the test, the patient is continuously monitored via electrocardiography (ECG) to detect any changes that may indicate coronary artery spasm. If the ECG shows alterations consistent with spasm, the chest pain is classified as cardiac in origin, specifically spasm-induced angina. Conversely, if no significant ECG changes are observed, the pain is attributed to esophageal spasm. Upon the onset of pain, immediate intervention is provided to alleviate the spasm, ensuring patient safety and comfort during the evaluation process.

The ergonovine provocation test is indicated for patients experiencing unexplained chest pain, particularly when there is no evidence of atherosclerotic coronary artery disease or other coronary abnormalities as confirmed by arteriography. This test is specifically useful in the following scenarios:
The ergonovine provocation test involves a series of carefully monitored steps to ensure accurate assessment of the patient's condition. The procedure is as follows:
After the ergonovine provocation test, the patient is monitored for any residual effects of the medication and to ensure that the chest pain has resolved. The healthcare provider will review the ECG findings and the patient's symptoms to determine the appropriate diagnosis and subsequent management plan. Patients may be advised to rest and avoid strenuous activities for a short period following the test, depending on their individual response and any medications administered during the procedure.

| 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. | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 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. | GC | This service has been performed in part by a resident under the direction of a teaching physician | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter |
