CPT code 93010 applies to professional interpretation and reporting of a 12-lead ECG, excluding cases where the physician performs the technical component. Proper billing depends on appropriate documentation, manifested medical necessity, and correct application of place of service and modifiers. Billing in alignment with payer policies, exclusion of duplicate charges, and the presence of a complete report assures coverage of denial avoidance and reimbursement, and also prevents claims from falling out of compliance with Medicare and/or commercial insurance rules.
Correct billing in cardiology necessitates an understanding of coding in the electrocardiogram (ECG) field, especially the coding for interpretations of services. One of the most frequently used codes for ECG interpretations is 93010. Many providers make the mistake of misinterpreting the meaning of this code, resulting in denials, underpayments, and compliance issues. In this guide, we explain the meaning of CPT code 93010, discuss the main billing rules, and provide some reimbursement advice.
.Understanding CPT 93010
CPT 93010 refers to the routine ECG interpretation report and is a code used when a physician or other qualified professional performs only the ECG service professional component. This, however, does not mean they do the technical part, which involves the actual ECG tracing.
An ECG is a test that is used to evaluate the electrical activity in the heart. The 12-lead ECG is the most common test used for the identification of arrhythmias, heart attacks, and other issues that may be present in the conduction of the heart. In most health care facilities, especially in the emergency department and other hospital departments, the technical portion of the test is carried out by the hospital staff, and the physician does separate billing for the interpretation of the test. CPT 93010 code is applicable in these scenarios.
Distinction from Other ECG Codes
93010 is unique from other ECG codes. For example, CPT 93000 is the global service that includes the tracing and the interpretation. CPT 93005 is the technical component only, meaning the tracing is done, but no interpretation is provided. Correct selection is based on who did what, under what arrangements, and what the service was.
Description of the Service
Interpretation and Report Requirements
For billing to be successful, the physician is required to document an interpretation and have a written report. The report cannot consist of only the phrase “normal ECG”. The report must include the clinical findings about the rhythm interpretation, special intervals, general axis assessment, and any noted abnormalities. The report needs to reflect the medical necessity of the findings in relation to the patient’s symptoms or the diagnosis.
It is not uncommon in a hospital for several physicians to look at the same ECG tracing. However, only the physician who is sitting on the interpretation that is related to the patient’s care and is in a separate document, may bill 93010. Duplicate billing for the same tracing may lead to an audit and generate a recoupment.
Criteria for Medical Necessity
Reimbursement hinges upon medical necessity. For an ECG to be deemed clinically warranted, a physician must provide a rationale, such as the patient experiencing complaints of chest pain or other presenting complaints suggestive of shortness of breath, an episode of syncope, or requests for hypertension evaluations as well as monitoring chronic cardiac conditions. The diagnosis code linked to 93010 must corroborate the need for the ECG to be interpreted.
Some payers may deny coverage for routine ECG screenings when performed without valid clinical symptomatic complaints or relevant risk factors. It is, therefore, upon the clinician to defend the medical necessity.
Billing Guidelines for CPT Code 93010
Professional Component Billing
CPT 93010 denotes only the professional service of the ECG. This implies that it is billed when the physician’s involvement is limited to providing an interpretation and a report and the physician does not provide the technical service of the tracing. In a hospital setup, the hospital generally bills the technical services using 93005 and the physician claims 93010.
In a situation where the physician’s office is where the ECG is performed and the physician does the tracing and the interpretation, the correct billing code is 93000 and not the combination of 93005 and 93010.
Use of Place of Service Codes and Modifiers
Place of service codes must be precise as to where a service is rendered. When billing 93010 in a hospital outpatient or inpatient setting, the correct hospital place of service code must be used. Reporting place of service codes incorrectly may result in underpayment of a claim or denial of a claim.
In certain situations, a modifier may be warranted. Modifier 26 is a case in point; it denotes a professional component when billing a code that has both a professional and technical component. Since 93010 is considered to represent the professional component, modifier 26 is not typically warranted when billing 93010. Providers should consult the policies of individual payers to determine modifier usage.
Count Limitations
Numerous payers utilize count edits to ECG services. While several ECGs may be medically warranted during an emergency visit or hospitalization, the absence of clear documentation to support multiple interpretations may raise eyebrows. When billing more than a single 93010 on the same date of service, the justification for repeated interpretations must be clear in the documentation.
If a patient presents with evolving chest pain, and multiple ECGs are done to track changes, each interpretation must be documented. Each interpretation should demonstrate a change, with distinct findings and should be time stamped.
Reimbursement Considerations
Medicare Reimbursement
Per the Medicare guidelines, CPT code 93010 is reimbursed according to the Medicare Physician Fee Schedule’s guidelines, which takes into account the geographical location of the provider as well as the annual conversion factor. Since 93010 is the professional component only, reimbursement is less than the global code 93000.
Medicare requires the interpreting physician to be enrolled, as well as credentialed, to the proper level, and the interpretation must be personally done as well as signed by the billing provider. Not signing the report could cause it to be denied in an audit.
Commercial Payer Policies
Commercial insurance does follow Medicare’s guidelines in many instances, but each payer can have their own policies. Some payers bundle the interpretation of ECGs into ED evaluation and management services, provided that the documentation does not support reimbursing them separately. To prevent the ECG from being denied, it is essential to be clear in the documentation that the ECG interpretation is separate from the E/M note.
Private payers may also impact their reimbursement and contract terms. Practices should periodically review payer contracts to ensure they are being paid according to agreed fee schedules.
Best Practice for Documentation
Comprehensive Reporting
All documents must have a detailed description of all procedures done because this will ensure Medicare will pay and the facility stays billing compliant. Each interpretation of an ECG must have a description of each of the following: any abnormal heart rhythms, heart rate, PR interval, the duration of the QRS, the duration of the QT interval if applicable, any axis deviation, and any significant abnormalities. Each interpretation must be signed and dated by the physician.
From a billing standpoint, a formal report must be done, and an ECG over-read cannot be done for billing code 93010. Each ECG done gets audited and the audit also reviews the physician’s report and documentation.
Linking to Diagnosis Codes
A denial of an ECG report can occur due to the diagnosis code assigned. The ICD-10 code used must reflect the diagnosis of the patient for the report to be billed. An ICD-10 code diagnosis of chest pain, arrhythmia, and ischemic heart disease meets the criteria of medical necessity for the ECG performance. A diagnosis that is unrelated is a sure way to have the claim denied.
Common Billing Errors
One of the greatest billing miscues within offices happens when billing 93010 rather than 93000 when reportable codes can be combined. An additional miscue is not providing a separate interpretation when billing a hospital stay.
Billing for services provided is a large area for potential risk. If an emergency physician and a cardiologist both interpret the same ECG, then only the cardiologist whose billing for 93010 is used for management and is appropriately documented can submit a claim. Internal policies should clarify some of these situations.
Practices should also pay attention to claim denials for bundling. If 93010 is denied for being part of an E/M service, then the documentation should be revised to show that the E/M documentation does not include the interpretive ECG for billing purposes.
Reimbursement Optimization Strategies
Conduct Regular Audits
Regular audits and internal reviews should be documented so that external audits do not have first claim to the information. Internal audits of a running sample of ECG interpretations can be helpful.
Educate Clinical Staff
Clinical staff should be educated and trained on documentation standards and payer policies and expectations so that denials are reduced.
Use Clear Templates
Formulaic ECG interpretation and reporting templates have been shown to increase the ease and confidence with which providers perform ECG interpretation, and as a result, they should be used to increase the ease and confidence and be available for extension.
Final Thoughts
CPT code 93010 is important for billing in cardiology and emergency medicine. It includes the professional side of an interpretation of a 12-lead ECG and requires a detailed report to get paid. Knowing the appropriate situations for the use of 93010 as opposed to 93000 or 93005 is critical for avoiding denials and other compliance issues. Regarding compliance, billing for reimbursement requires accurate documentation of the medical necessity and the correct application of billing rules along with knowledge of the policies of the payers. This provides a framework for the enforcement of both sides of the equation–spending the time to maintain detailed controls along with the regular application of the required auditing functions for reimbursement to be justified.
Make An Appintment With A2ZFAQs
CPT code 93010 only includes the professional component of a 12-lead electrocardiogram (ECG) which is the physician’s interpretation and written report. It definitely excludes the technical part of performing and recording the ECG tracing. To qualify for payment, the interpretation must be dictated and signed.
CPT code 93010 should be billed when the physician does only the interpretation and report, which is usually in a hospital, or a facility, where the technical part is done by the facility. CPT code 93000 is applicable when the technical and professional parts are done in the same office.
Modifier 26 is almost never necessary with billing 93010 since the code, by virtue, is assumed to be the professional component only. Nevertheless, providers should be careful to check the rules of individual payers as some insurers have special rules that may require such.
Documentation must include a descriptive interpretation with rhythm analysis, heart rate, intervals, axis, and clinical impression. Reports saying “ECG normal” are insufficient. The report must be signed and be tied to a diagnosis that is deemed medically necessary.
As a rule, only the physician whose interpretation is integrally involved in patient management and is stated separately may bill 93010. If medical necessity is documented to support multiple distinct interpretations, it may result in claim denials or auditing problems if the same ECG tracing is billed multiple times.
