Article Guidance

Article Text


This Billing and Coding Article provides billing and coding guidance for Local Coverage Determination (LCD) L38396 Cardiology Non-Emergent Outpatient Stress Testing. Please refer to the LCD for reasonable and necessary requirements.

Coding Guidance

Notice: It is not appropriate to bill Medicare for services that are not covered (as described by the entire LCD) as if they are covered. When billing for non-covered services, use the appropriate modifier.

Current Procedural Terminology (CPT) code 78434 should be reported in conjunction with CPT code 78431 or 78492.

Evaluation of the individual’s left ventricular wall motion and ejection fractions are routinely performed during SPECT MPI and are included in the code’s definition.

Attenuation correction, when performed, is included in the MPI service.

Documentation Requirements

  1. All documentation must be maintained in the patient's medical record and made available to the contractor upon request.
  2. Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service[s]). The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.
  3. The submitted medical record must support the use of the selected ICD-10-CM code(s). The submitted CPT/HCPCS code must describe the service performed.
  4. If the provider of the service is other than the ordering/referring physician, the provider of the service must maintain hard copy documentation of test results and interpretation, along with copies of the ordering/referring physician’s order for the studies.
  5. The ordering physician must state the clinical indication/medical necessity for the study in the order for the test.
  6. Documentation must be maintained by the referring physician in the beneficiary’s medical record that the required conditions (as indicated in the “Coverage Indications, Limitations and/or Medical Necessity” section of the LCD) for the stress test performed have been met.
  7. The rationale for selecting pharmacologic stress testing rather than exercise stress testing must be documented in the medical record.
  8. In the instance where regional wall motion abnormalities and ejection fraction have been assessed during the same episode of care by other testing modalities (e.g., echocardiography), the medical necessity of repeating this assessment through the use of nuclear imaging modalities must be clearly documented in the medical record.
  9. All segments of the service must have a formal interpretation and report.

ICD-10-CM Codes that Support Medical Necessity

Group 1

(306 Codes)
Group 1 Paragraph


It is the provider’s responsibility to select codes carried out to the highest level of specificity and selected from the ICD-10-CM code book appropriate to the year in which the service is rendered for the claim(s) submitted.

The following ICD-10-CM codes support medical necessity and provide coverage for CPT codes: 93015, 93016, 93017, and 93018.

Group 1 Medical Necessity ICD-10-CM Codes Asterisk Explanation


*ICD-10 codes I12.0, I13.11, and I13.2, require that ICD-10 code N18.5 or N18.6 also be reported to identify the stage of chronic kidney disease.

*For ICD-10 codes I12.9, I13.0, and I13.10, use an additional ICD-10 code N18.1, N18.2, N18.31, N18.32 or N18.4 to identify the stage of chronic kidney disease.

*For ICD-10 codes I09.81, I11.0, I13.0 and I13.2, use an additional ICD-10 code I50.1, I50.21, I50.22, I50.23, I50.31, I50.32, I50.33, I50.41, I50.42, I50.43, I50.811, I50.812, I50.813, I50.814, I50.82, I50.83, I50.84, or I50.89 to identify type of heart failure.

*Use ICD-10 code R77.8 for an elevated cardiac troponin.

*Use ICD-10 code R93.1 for recently demonstrated coronary stenosis of uncertain functional significance on a coronary angiogram or CCTA and for coronary calcium Agatston score >400.

*Use ICD-10 code R94.31 for > 1 mm ST segment depression, LVH with repolarization abnormalities, short Q waves or an abnormality that has not yet been identified on the EKG indicating a need for a stress test.

*Use ICD-10 code Z79.899 for patients who will be treated with an interleukin-2 product and for imaging indications related to patients on digoxin, beta blocker, calcium channel blocker and/or other antiarrhythmic medication therapy.

*For ICD-10 codes I12.0, I13.11, and I13.2, use an additional ICD-10 code N18.5 or N18.6 to identify the stage of chronic kidney disease.

*For ICD-10 codes I12.9, I13.0, and I13.10, use an additional ICD-10 code N18.1, N18.2, N18.31, N18.32, or N18.4 to identify the stage of chronic kidney disease.

*For ICD-10 codes I09.81, I11.0, I13.0 and I13.2, use an additional ICD-10 code I50.1, I50.21, I50.22, I50.23, I50.31, I50.32, I50.33, I50.41, I50.42, I50.43, I50.811, I50.812, I50.813, I50.814, I50.82, I50.83, I50.84, or I50.89 to identify type of heart failure.

Group 3 Medical Necessity ICD-10-CM Codes Asterisk Explanation


*For ICD-10 codes I12.0, I13.11, and I13.2, use an additional ICD-10 code N18.5 or N18.6 to identify the stage of chronic kidney disease.

*For ICD-10 codes I12.9, I13.0, and I13.10, use an additional ICD-10 code N18.1, N18.2, N18.31, N18.32, or N18.4 to identify the stage of chronic kidney disease.

*For ICD-10 codes I09.81, I11.0, I13.0 and I13.2, use an additional ICD-10 code I50.1, I50.21, I50.22, I50.23, I50.31, I50.32, I50.33, I50.41, I50.42, I50.43, I50.811, I50.812, I50.813, I50.814, I50.82, I50.83, I50.84, or I50.89 to identify type of heart failure.

*Use ICD-10 code I49.8 for Brugada Syndrome.

*Use ICD-10 code R93.1 for recently demonstrated coronary stenosis of uncertain functional significance on a coronary angiogram or CCTA and for coronary calcium Agatston score >400.

*Use ICD-10 code R94.31 for > 1 mm ST segment depression, LVH with repolarization abnormalities, short Q waves or an abnormality that has not yet been identified on the EKG indicating a need for a stress test.

*Use ICD-10 code R94.39 when an abnormal or non-diagnostic stress test is the reason cardiac imaging is being performed.

*Use ICD-10 code Z79.899 for patients who will be treated with an interleukin-2 product and for imaging indications related to patients on digoxin, beta blocker, calcium channel blocker and/or other antiarrhythmic medication therapy.

Group 4 Medical Necessity ICD-10-CM Codes Asterisk Explanation


*For ICD-10 codes I12.0, I13.11, and I13.2, use an additional ICD-10 code N18.5 or N18.6 to identify the stage of chronic kidney disease.

*For ICD-10 codes I12.9, I13.0, and I13.10, use an additional ICD-10 code N18.1, N18.2, N18.31, N18.32, or N18.4 to identify the stage of chronic kidney disease.

*For ICD-10 codes I09.81, I11.0, I13.0 and I13.2, use an additional ICD-10 code I50.1, I50.21, I50.22, I50.23, I50.31, I50.32, I50.33, I50.41, I50.42, I50.43, I50.811, I50.812, I50.813, I50.814, I50.82, I50.83, I50.84, or I50.89 to identify type of heart failure.

*Use ICD-10 code I49.8 for Brugada Syndrome.

*The billing for the evaluation for cardiac sarcoidosis requires dual diagnoses. Use ICD-10 code I43 with an appropriate ICD-10 code D86.0, D86.1, D86.2, D86.3, D86.81, D86.82, D86.83, D86.84, D86.85, D86.86, D86.87, or D86.89.

*Use ICD-10 code R77.8 for an elevated cardiac troponin.

*Use ICD-10 code R93.1 for recently demonstrated coronary stenosis of uncertain functional significance on a coronary angiogram or CCTA and for coronary calcium Agatston score >400.

*Use ICD-10 code R94.31 for > 1 mm ST segment depression, LVH with repolarization abnormalities, short Q waves or an abnormality that has not yet been identified on the EKG indicating a need for a stress test.

*Use ICD-10 code R94.39 when an abnormal or non-diagnostic stress test is the reason cardiac imaging is being performed.

*Use ICD-10 code Z79.899 for patients who will be treated with an interleukin-2 product and for imaging indications related to patients on digoxin, beta blocker, calcium channel blocker and/or other antiarrhythmic medication therapy.
