Cardiology Coding Alert

Use New Transport Codes to Bill Time in Ambulance

CPT 2002 introduced a pair of new E/M codes to report critical care services provided by the cardiologist during transport from one facility to another. Although Medicare does not recognize these codes and instructs physicians to use existing critical care codes instead, the new codes provide more accuracy when cardiologists bill private carriers that recognize them, says Nikki Vendegna, CPC, a cardiology coding and reimbursement specialist in Overland Park, Kan.

The two codes are:

  • 99289 Physician constant attention of the critically ill or injured patient during an interfacility transport; first 30-74 minutes
  • +99290 each additional 30 minutes (list separately in addition to code for primary service).

    According to CPT, these codes should be used to report direct, face-to-face care by the physician only.

    Using the Time-Based Codes

    Like the critical care codes (99291-99292), the transportation codes are time-based, Vendegna says. You should report the first 30 to 74 minutes of time spent in direct, face-to-face contact with the patient during transportation using 99289, whereas 99290 should be used for any subsequent time that takes at least 30 minutes. If the transportation takes less than 30 minutes, another E/M code (not critical care) must be reported.

    Note: Because CPT instructs physicians to report 99290 in 30-minute increments, this code may need to be reported more than once, either by listing the code multiple times or by listing the increments in the units box of the CMS 1500 claim form.

    To correctly bill time-based codes, you must monitor and document the amount of direct, face-to-face time the cardiologist spends with the patient during transport, Vendegna says.

    At least half the time specified in any time-based code must be documented. That means that when billing 99289 (one hour), the physician's notes must describe at least 30 minutes of face-to-face care. Similarly, at least 15 minutes must be documented for each (30-minute) unit of 99290. Although not required, start and stop times should be included, whenever possible.

    According to CPT, the following should not be considered when determining how to code such services appropriately:

  • Procedures performed by other members of the transporting team
  • Procedures or services performed by the cardiologist before transport
  • Separately payable procedures or services performed during transport (these include most services other than routine monitoring evaluations, such as heart rate, respiratory rate, blood pressure and pulse oximetry)
  • Physician-directed care by telephone (CPT states this service may be reported with code 99288 [Physician direction of emergency medical systems (EMS) emergency care, advanced life support], butMedicare's fee schedule maintains this is a "bundled" code, i.e., always part of another procedure.)

    The time spent performing any of these procedures or services should not be included when calculating the amount of time involved in the transport of the critically ill or injured patient.

    Any time spent treating the patient or coordinating care before the cardiologist assumes primary responsibility of the patient at the referring hospital or facility should not be included. And the time spent performing face-to-face care during transport ends "when the receiving hospital/facility accepts responsibility for the patient's care," CPT says.

    These codes should not be billed in conjunction with 99082 (Unusual travel [e.g., transportation and escort of patient]). This carrier-priced code is used when a physician travels with a patient who is not critically ill or injured.

    According to section 15026 of the Medicare Carriers Manual, this type of travel is generally already incorporated in the practice expense relative value units (RVUs) of any given procedure or service and is not separately payable. But carriers may pay separately if the physician "submits documentation to demonstrate that the travel was very unusual."

    Medicare and Private Payers

    The Medicare fee schedule says 99289 and 99290 have an "I" status, which means the codes are not valid for Medicare purposes. The fee schedule states that for such codes, "Medicare uses another code for reporting of, and payment for, these services."

    Private payers may accept codes with the highest degree of specificity, based on CPT guidelines. Not only do 99289 and 99290 more accurately describe travel with a critically ill or injured patient, but the 2002 CPT manual specifically says in the introduction to the critical care section that "codes 99291-99292 should not be reported for the physician's attendance during the transport of critically ill or injured patients to or from a facility or hospital. Physician transport services of critically ill or injured patients are separately reportable, see 99289, 99290."

    Therefore, unless specifically instructed not to use these codes by your payer, you should report such services with the new patient transport codes.

    According to Marko Yakovlevitch, MD, FACP, FACC, a cardiologist in private practice in Seattle, accompanying a patient during transport is rare, but it does happen.

    Yakovlevitch cites the following example: A 62-year-old woman with chest pain and hypotension presents at a rural hospital and is found to have an acute anterior wall infarction. She has a history of intracranial hemorrhage and therefore is not a candidate for thrombolytic therapy. The hospital does not have a cardiac catheterization laboratory. The cardiologist at the hospital administers aspirin and intravenous heparin and starts intravenous dopamine to support her blood pressure. He is concerned that she is having a large infarct and needs acute angioplasty to open the obstructed artery.

    The patient remains unstable, so he decides to accompany the patient to a larger hospital in a nearby town. The trip takes 35 minutes, all of which the cardiologist spends face-to-face with the patient providing supportive therapy before the receiving hospital takes responsibility for her care.

    In this case, the care provided to the woman during transport should be reported with 99289, assuming that at least 30 minutes of the face-to-face time the cardiologist spent with the patient is documented. The woman is not a Medicare beneficiary, and the private carrier prefers the new codes to critical care codes so utilization trends can be monitored.
