Cardiology practices operate in one of the most complex billing environments in healthcare. They must navigate multi-step diagnostic workflows, invasive procedures, device monitoring, strict NCCI edits, payer-specific documentation rules, and extensive prior authorization requirements. Because of this complexity, many practices turn to outsourced billing companies for revenue cycle support.
But not all billing companies offer the same level of service—especially when it comes to EHR integration. Some companies work outside the EHR using manual imports, while others provide deep integration that connects scheduling, documentation, coding, charge capture, and claims submission inside a unified system.
This article compares different types of cardiology billing companies based on how well they integrate with EHR platforms and how those integrations impact accuracy, workflow efficiency, and denial reduction.
Why EHR Integration Matters in Cardiology Billing
Before comparing companies, it’s important to understand why integration is so crucial in cardiology.
1. Multi-step clinical workflows
Cardiology involves:
- Office visits
- Echo
- Stress tests
- Nuclear imaging
- Holter and event monitoring
- Cath/PCI procedures
- EP studies
- Device checks (remote + in-person)
Each element produces documentation that must flow accurately into billing.
2. High volume of technical and professional components
Most cardiology services involve:
- Technical component (TC)
- Professional interpretation (26)
Poorly integrated systems cause mismatched charges or missing components.
3. Frequent changes in Medicare and commercial payer rules
LCD/NCD requirements, device frequency rules, and NCCI edits require real-time updates.
4. Multiple data sources
Cardiology practices often use:
- EHR
- PACS or imaging systems
- Device monitoring platforms
- Hospital portals
- Scheduling systems
- Separate cath lab documentation systems
- External labs
Billing accuracy relies on correctly syncing these workflows.
Because of these complexities, billing companies with limited or no EHR integration often struggle to submit complete, timely, and accurate claims.
Types of Cardiology Billing Companies (Based on EHR Integration)
There are three main categories of cardiology billing companies.
1. Billing Companies With No Direct EHR Integration
These companies perform billing outside the EHR completely.
They request exported reports or scanned documents to create claims.
Common methods:
- Manual charge sheets
- Faxed encounter forms
- Scanned visit notes
- End-of-day or weekly exported reports
- CSV batch files from the EHR
Advantages:
- Lower cost
- Minimal onboarding effort
- Suitable for very small practices
- Works even if the EHR has no API or integration tools
Disadvantages (Significant for Cardiology):
- High risk of missing charges
- Missing technical or professional components
- Missing add-on codes
- Delayed documentation transfer
- Inaccurate coding due to incomplete clinical detail
- No real-time eligibility or documentation visibility
- Slow pathway for prior authorization coordination
- High frequency of front-end errors
- Limited ability to track device monitoring intervals
- Manual review of NCCI edits
Best suited for:
Solo providers with low procedural volume and minimal technical billing.
For multi-provider cardiology groups, this model is generally not recommended due to risk of claim leakage and incomplete documentation.
2. Billing Companies With Partial or Indirect EHR Integration
These companies connect to the EHR using:
- Daily HL7 feeds
- Batch exports
- Portal access to reports
- Shared work queues
- Partial API-level data pulls
- Direct read-only access to clinical documentation
This is the most common category across billing vendors.
Advantages:
- More accurate charge capture
- Faster access to clinical notes
- Better visibility into procedure reports
- Improved modifier accuracy
- Easier auditing
- Higher clean claim rate than non-integrated companies
Limitations:
- Not fully real-time
- Imaging and device monitoring platforms may not sync
- Separate cath lab systems often remain siloed
- Add-on codes and NCCI edit validation still require manual checks
- Prior authorization workflows may still be outside the EHR
- Documentation templates are not standardized through the billing vendor
- Cannot fully automate charge capture
Best suited for:
Medium-sized cardiology practices with:
- Moderate procedural volume
- EHRs that allow partial integration (eClinicalWorks, Kareo, DrChrono, etc.)
This category works well, but the practice will still experience some manual processes.
3. Billing Companies With Full, Deep, Real-Time EHR Integration
These companies integrate deeply using:
- Real-time HL7
- Full API connections
- Embedded charge capture modules
- Integrated authorization and order management
- Direct access to clinical documentation
- Automatic syncing of imaging, device data, and cath lab reports
- Real-time NCCI edit engines
- EHR-based rule sets for cardiology-specific coding
What deep integration looks like:
- Charges flow automatically from the clinical workflow
- Echo, stress, and nuclear reports sync directly
- Device checks sync from in-person and remote systems
- Cath/PCI documentation flows into structured billing templates
- Modifiers and add-on codes auto-generate based on documentation
- ICD-10 suggestions align with medical necessity policies
- Prior authorizations appear inside scheduling and charge screens
Advantages:
- Highest clean claim rate
- Fewer missing charges
- Faster claim submission
- Reduced documentation errors
- Strong NCCI, MUE, and LCD/NCD compliance
- Better frequency limit management (remote monitoring + device checks)
- Easier auditing
- Improved communication between clinical and billing teams
Limitations:
- Higher onboarding effort
- Requires EHR compatibility
- Often more expensive
- Requires training for clinicians and billing teams
Best suited for:
High-volume cardiology groups with:
- Multiple providers
- Multiple locations
- Cath lab or EP lab volume
- Stress echo/nuclear cardiology programs
- Ongoing device monitoring needs
For these practices, deep integration often leads to the highest revenue stability and lowest denial rates.

Final Thoughts
Choosing a cardiology billing company begins with assessing how deeply it integrates with your EHR. Companies with no integration often struggle with missing charges and documentation delays. Partially integrated vendors offer improvements but still require manual coordination. Fully integrated billing companies provide the most accurate, efficient, and denial-resistant workflow—especially for multi-provider cardiology groups.
Organizations such as Global Tech Billing LLC often work with practices to evaluate EHR compatibility and implement structured workflows that align charge capture, documentation, and claims submission within a unified system.
FAQs
1. Why is EHR integration important for cardiology billing?
Because cardiology involves multi-step procedures and separate technical/professional components that must sync accurately.

Partial integration relies on limited data feeds, while full integration provides real-time syncing of documentation, charges, imaging, and device monitoring.
3. Do billing companies without integration cause more denials?
Typically yes—due to missing documentation, missing charges, and inaccurate coding.
4. Which model offers the most accurate charge capture?
Full, real-time EHR integration.
5. Can non-integrated companies still work for small practices?
Yes, but only for low-volume cardiology practices with limited technical billing.
6. What type of integration is best for high-volume cath or EP labs?
Deep, real-time EHR integration with structured charge capture and NCCI logic.
