Correct Coding Initiative (CCI) describes correct usage of the 59 modifier for repeat procedural services performed on the same day.CMS Manual System, Publication 100-03,Medicare National Coverage Determinations Manual,Chapter 1, 20.15, Electrocardiogram Service, "No payment is made for EKG interpretations by individuals other than physicians' and "A separate charge by an attending or consulting physician for EKG interpretation is allowed only when it is the normal practice to make such charge".CMS Manual System, Publication 100-02,Medicare Benefit Policy Manual,Chapter 15, 190 and 200, allow for services supplied by physician assistants and nurse practitioners.CMS Manual System, Publication 100-02,Medicare Benefit Policy Manual,Chapter 15, 250, states that payment may be made under Part B for the medical and other health services enumerated in paragraph C, but only where no payment can be made for such services under Part A.Article TextThe following billing and coding guidance is to be used with its associated Local Coverage Determination.Coding Guidelines:The results of the ECG must be relevant to the management of the patient.When an ECG is performed on the same day as a cardiac stress test, but is not part of that stress test, it is separately payable. The ECG must add additional information to the stress test. For example, an ECG may be reasonable and necessary to rule out an acute MI prior to a same day stress ECG performed to evaluate possible accelerating angina. Typically, when the ECG stress test is scheduled in advance, a separate ECG on the same day is not reasonable and necessary.An ECG is not a covered benefit when used for screening purposes or as part of a routine physical examination. Routine physical examinations (screening) are evaluation and management services supplied in the absence of associated signs, symptoms or complaints. These services are denied as not a benefit of the Medicare program. Patients may choose to pay privately for these services.A second ECG performed to replace a technically inadequate ECG may not be reported as an additional service.Rhythm ECGs are used to evaluate signs and symptoms that may reflect a cardiac rhythm disorder.A rhythm ECG interpretation and report only (93042) is included in a 12-lead ECG interpretation and report (93000 or 93010).A rhythm ECG tracing (93040 or 93041) is included in a 12-lead ECG tracing (93000 or 93005).When several ECG rhythm (or monitor) strips from a single date of service are reviewed at a single setting, report only one unit of service, regardless of the number of strips reviewed.If one physician bills a rhythm strip interpretation, and another physician bills an ECG interpretation for the same patient on the same date of service, then both services must be reasonable and necessary. Typically, the patient will receive and requireprolongedrhythm monitoring in addition to a 12-lead ECG.An ECG furnished on anemergencybasis by a laboratory or a portable X-ray supplier requires that a physician be in attendance at the time the service was performed or immediately thereafter.Payments for a home-based ECG above the ECG base amount (i.e., for transportation costs) requires a medical need for performing the service in the patient's home, in addition to the need for the ECG itself. Typically, qualifying patients will be homebound or bed-confined.Payment for the technical component of an ECG will be denied when the facility is paid for the technical component through the fiscal intermediary (i.e., during a Part A covered nursing home stay). In these cases, the ECG supplier is paid by the facility under a contract arrangement.Payment for more than one Professional Component (PC) of a single ECG:Medicare will not pay twice for a service that is required only once to diagnose or treat an illness or injury. Typically, this A/B MAC will pay for only one PC of an ECG. This A/B MAC may pay for a second PC when the additional physician expertise is necessary and reasonable to diagnose or treat the patient, such as to clarify a questionable finding. The physician performing the initial PC must have a valid reason to require another physicians expertise, such as, to interpret a confusing ECG. The second physician's knowledge and expertise must be significantly greater than that of the first reader, and it must contribute substantially to the interpretation.Multiple Interpretations of a Diagnostic Test in Institutional Settings:Medicare generally pays for only one reading of a diagnostic test. Medicares rules are clearly explained in the Internet-Only Manual, Pub. 100-04, Medicare Claims Processing Manual, Chapter 13, Section 100.1 which made clear with public notice and comment that CMS policy would not pay for routine second readings). While Chapter 13 is titled, Radiology Services, Section 100.1 is titled X-rays and EKGs furnished to Emergency Room Patients. The principles apply to double-readings of diagnostic tests in general. The following paragraphs quote extensively from Section 100.1. [Emphasis added by this A/B MAC]Generally, A/B MACs (B) must pay for only one interpretation of an EKGor x-ray procedure furnished to an emergency room patient. They pay for a second interpretation (which may be identified through the use of modifier -77)only under unusual circumstances(for which documentation is provided) such as a questionable finding for which the physician performing the initial interpretation believes another physicians expertise is needed or a changed diagnosis resulting from a second interpretation of the results of the procedure. When A/B MACs (B) receive only one claim for an interpretation, they must presume that the one service billed was a service to the individual beneficiary rather than a quality control measure and pay the claim if it otherwise meets any applicable reasonable and necessary test.When A/B MACs (B) receive multiple claims for the same interpretation, they must generally pay for the first bill received. A/B MACs (B) must pay for the interpretation and report that directly contributed to the diagnosis and treatment of the individual patient. Consideration is not given to physician specialty as the primary factor in deciding which interpretation and report to pay regardless of when the service is performed. Consideration is not given to designation as the hospitals official interpretation as a factor in determining which claim to pay. A/B MACs (B) pay for the interpretation billed by the cardiologist or radiologist if the interpretation of the procedure is performed at the same time as the diagnosis and treatment of the beneficiary. (This interpretation may be an oral report to the treating physician that will be written at a later time.) [End quotations]Section 100.1 provides one example of a medically appropriate double payment for a second interpretation, an example where an ER physician diagnoses pneumonia but a radiologist provides a requested second reading for possible tumor. For double reading of an EKG, a similar circumstance must apply, an unusual reason why a second interpretation (for example, a reading by a cardiologist) was specifically medically necessary. Otherwise, the second interpretation must be denied per the manual as a quality control service.Alternatively, if the first physician defers diagnosis with a telegraphic note and passes the test to the second physician for his/her diagnostic interpretation, only the second physician should bill. Chapter 13, Section 100.1 states that a telegraphic note in an E/M record is considered part of the E/M service and not a separate report. For example, a treating physician may see an x-ray with a radiologists report of a fractured tibia, and he may note x-ray, fx tibia in his E/M summary, but he may not charge an additional radiologic interpretation fee. The CMS manual states as follows:A/B MACs (B) generally distinguish between an interpretation and report of an x-ray or an EKG procedure and a review of the procedure. A professional component billing based on a review of the findings of these procedures, without a complete, written report similar to that which would be prepared by a specialist in the field, does not meet the conditions for separate payment of the service. This is because the review is already included in the emergencydepartment evaluation and management (E/M) payment. For example, a notation in the medical records saying fx-tibia or EKG-normal would not suffice as a separately payable interpretation and report of the procedure and should be considered a review of the findings payable through the E/M code. An interpretation and report should address the findings, relevant clinical issues, and comparative data (when available). [end quotation.]Each payable interpretation must include a complete, written report similar to one that is prepared by a specialist in the field. The content of the written report must address the relevant clinical issues, available comparative data, and test findings. The format of the report must be separately identifiable. It may be included under a separate heading within the clinical record or written on the ECG tracing itself, with a reference in the clinical record.Documentation Guidelines:Supportive documentation evidencing the condition and treatment is expected to be documented in the medical record and be available upon request.An interpretation and report must address the findings and comparative data, if available (i.e., a prior ECG).The patients medical record must be legible and clearly indicate the reasonableness and necessity of the service.The documentation must show that the service was reasonable and necessary for at least one of the covered conditions in this policy.A laboratory or a portable X-ray supplier that supplies an ECG must maintain in its records the referring physicians written order and the identity of the employee taking the tracing.Patients presenting with an acute ischemic episode may require several ECGs on one or more days to delineate the severity and progression of that episode when needed to properly treat the patient.Unstable patients (e.g., electrolyte imbalance, recurrent rhythm disturbances, recurrent chest pain) may require more than one ECG annually to diagnose the condition or assess response to treatment.Typically, patients with chronic stable heart disease, or other diseases potentially affecting the heart do not require an ECG more frequently than annually.
