Top 5 Radiology Billing Companies to Outsource

Last Updated on September 3, 2025 by admin

Radiology billing in 2025 isn’t what it was even a few years ago. 

With CMS tightening policies, payers putting medical necessity under a microscope, and coding guidelines growing more complex, especially for modalities like interventional radiology, billing has evolved from a back-office function to a strategic revenue driver. 

Practices now face higher denial rates, under-coding risks, and slower reimbursements, all of which strain cash flow and compliance if not managed well.

These challenges highlight the need for robust radiology denial management strategies that focus on clean claim submission and accurate coding.

This year’s Medicare Physician Fee Schedule brought even more pressure, cutting the conversion factor by 2.83% and reducing reimbursement for high-volume like CT and MRI by up to 4.4%. For radiology groups, that means doing more with less, and doing it correctly every time.

Today, the best radiology billing companies aren’t just claims processors; they’re true partners who combine specialty expertise, compliance rigor, and smart automation to keep your revenue cycle strong and adaptable. 

As technology and regulations keep shifting, having the right billing partner can make the difference between staying profitable and falling behind.

Understanding What Impacts Radiology Billing Costs

Outsourcing your radiology billing can significantly improve collections and reduce denials, but understanding how pricing works helps you make the right decision for your practice.

Most radiology billing companies charge a percentage of net collections, while some offer flat-rate or per-claim pricing for higher volumes. Costs can vary based on your speciality mix and the level of support you need. For example, interventional radiology cases typically require more experienced coders and closer payer scrutiny, which can affect pricing.

Here are a few factors that can influence your cost:

• Claim Volume: Higher volumes often qualify for lower rates because your billing partner can spread costs more efficiently.
• Case Complexity: Practices with complex procedures or high volumes of prior authorizations may pay more than diagnostic-only imaging centers.
