Reimbursement
1. Getting Started
1.1 Choose Your Billing Path
Before diving into the details, determine which billing process applies to your situation:
Hospital/Facility Billing – For billing facility fees in hospital outpatient settings:
- Bills for equipment, room, technical staff
- Uses standard hospital outpatient methodology
- Maps to APC 5734 with established payment rates
Provider/Professional Billing – For billing physician or other provider professional fees:
- Bills for physician interpretation and clinical decision-making
- Requires crosswalk methodology due to no established RVUs
1.2 Hospital vs Provider Decision Tree
What are you billing for?
Hospital facility fees (equipment, room, tech staff)? → Go to Section 2: Hospital Facility Billing
Physician professional fees (interpretation, clinical decisions)? → Go to Section 3: Provider Professional Billing
Both facility and professional components? → Use both Section 2 and Section 3 for respective components

Frequently Asked Questions
7.1 Facility vs Professional Billing
Q: What’s the difference between facility and professional billing for ECG-AI LEF?
A: These are completely different billing processes:
FACILITY BILLING (Hospital):
- Bills for equipment, room, technical staff
- Uses standard hospital outpatient methodology
- Maps to APC 5734 with established payment rates
- Minimal additional documentation required
- High success rates with fast processing
PROFESSIONAL BILLING (Provider):
- Bills for physician interpretation and clinical decision-making
- Requires crosswalk methodology due to no established RVUs
- Extensive documentation and justification needed
- More complex appeals process
- Variable success rates depending on documentation quality
Q: Do I need crosswalk billing if I’m a hospital?
A: NO – Hospitals billing facility fees use standard APC methodology. CPT codes 0764T and 0765T map to APC 5734 with established payment rates.
Crosswalk billing ONLY applies to professional fees where physicians bill for interpretation and clinical decision-making.
Q: Can the same ECG-AI LEF procedure have both facility and professional fees?
A: YES – This is common in hospital settings:
- Hospital bills facility fee using 0764T/0765T (maps to APC 5734)
- Physician bills professional fee using same codes with modifier if needed (requires crosswalk methodology)
Q: What is APC 5734?
A: APC 5734 is the Medicare Ambulatory Payment Classification for ECG-AI LEF facility services:
- Classification: Level 4 Clinic Visits
- 2025 Payment Rate: $128.90 (Medicare national average, varies by geographic area)
- Relative Weight: 1.812
- Both 0764T and 0765T map to this APC
7.2 General Billing Questions
Q: What are CPT codes 0764T and 0765T?
A: These are Category III CPT codes assigned by the AMA for Anumana’s ECG-AI LEF technology:
- 0764T: AI analysis performed concurrently with ECG (add-on code)
- 0765T: AI analysis of previously performed ECG (stand-alone code)
Q: Why can’t I just bill these codes like any other CPT code?
A: This depends on whether you’re billing facility or professional fees:
For Hospital Facility Fees: You CAN bill them like other CPT codes! They map to APC 5734 with established payment rates.
For Professional Fees: Category III codes don’t have assigned Relative Value Units (RVUs) or established payment rates. Payers have discretion in coverage decisions, often resulting in denials without proper justification. Crosswalk billing is required (see section 3.2)
7.3 CPT Code Selection
Q: When should I use 0764T vs 0765T?
A: Use this decision tree:
ECG and AI analysis same day?
YES → 0764T (with 93000 for ECG)
NO → 0765T (stand-alone)
Patient visit includes ECG?
YES → 0764T
NO → 0765T
Retrospective ECG analysis?
YES → 0765T
NO → 0764T
Q: Can I bill both 0764T and 0765T for the same patient?
A: Not for the same ECG analysis. Choose one based on the clinical scenario:
- Same-day ECG + ECG-AI LEF = 0764T
- Previous ECG + new ECG-AI LEF analysis = 0765T
7.4 Medical Necessity
Q: What clinical scenarios justify ECG-AI LEF analysis?
A: The Anumana Low Ejection Fraction AI-ECG Algorithm is software intended to aid in screening for Left Ventricular Ejection Fraction (LVEF) less than or equal to 40% in adults at risk for heart failure. This population includes, but is not limited to:
- patients with cardiomyopathies
- patients who are post-myocardial infarction
- patients with aortic stenosis
- patients with chronic atrial fibrillation
- patients receiving pharmaceutical therapies that are cardiotoxic, and
- postpartum women.
Anumana Low Ejection Fraction AI-ECG Algorithm is not intended to be a stand-alone diagnostic device for cardiac conditions, should not be used for monitoring of patients, and should not be used on ECGs with a paced rhythm.
A positive result may suggest the need for further clinical evaluation in order to establish a diagnosis of Left Ventricular Ejection Fraction (LVEF) less than or equal to 40%. Additionally, if the patient is at high risk for the cardiac condition, a negative result should not rule out further non-invasive evaluation.
The Anumana Low Ejection Fraction AI-ECG Algorithm should be applied jointly with clinician judgment.
Q: Is ECG-AI LEF analysis covered for asymptomatic patients?
A: Yes, when appropriate risk factors are present. Document:
- Specific risk factors (diabetes, hypertension, family history)
- Clinical rationale for screening
- Potential impact on patient management
7.5 Technical Process
Q: Which crosswalk CPT codes work best?
A: Providers must use their own judgement when selecting appropriate crosswalk codes. The following codes have been accepted as successful crosswalks for professional billing:
- 93000 (ECG interpretation) – Similar physician work
- 93005 (ECG tracing) – Equipment and technical components
- 76700 (Abdominal ultrasound) – Similar interpretation complexity
- Select based on your specific work effort analysis
Q: How do I track billing success?
A: Monitor these metrics:
- Approval rate (target: >75% for professional, >90% for facility)
- Average payment amount (target: 60-80% of crosswalk allowable for professional, ~100% APC for facility)
- Time to payment (target: <60 days for professional, <21 days for facility)
- Denial reasons (for process improvement)
7.6 Compliance and Legal
Q: Is crosswalk billing compliant?
A: Yes, crosswalk billing is an established, accepted methodology for Category III codes. Ensure:
- Accurate clinical documentation
- Honest representation of services
- Proper code selection based on actual services performed
- Compliance with all applicable laws and regulations
Q: How often should I update my crosswalk analysis?
A: Review crosswalk selections:
- Quarterly – for process optimization
- When RVU values change – typically annually
- After significant denials – reassess approach
- With new clinical evidence – incorporate latest data
7.7 Implementation
Q: How do I get started if I’m new to this?
A: Hospital Facility Billing:
- Set up charge master entries for 0764T/0765T
- Train staff on basic documentation requirements
- Implement standard billing workflow
- Monitor early outcomes
Professional Billing:
- Review comprehensive materials – Study crosswalk methodology
- Select simple case – Choose straightforward clinical scenario
- Use all templates – Follow guides exactly for first few claims
- Track outcomes – Monitor success and identify improvements
- Scale gradually – Expand volume as process improves
