Radiology Billing Services
Specialized revenue cycle management for radiology groups, imaging centers, and teleradiology companies. We handle modifier 26/TC split billing, CPT coding, prior authorization, NCCI compliance, and full denial management across every imaging modality.
Why Radiology Billing Is Different
The Most Technically Complex Billing Specialty in Medicine
Radiology billing sits at the intersection of procedural medicine, diagnostic interpretation, and facility operations — and it requires mastery of all three. Unlike most medical specialties where a physician performs and bills a single service, radiology routinely involves split billing between the professional and technical components: the radiologist bills for the interpretation, while a separate entity bills for the imaging equipment, technologist, and facility overhead.
This bifurcation — governed by modifiers 26 and TC — creates an entire layer of billing complexity that most generalist billers handle incorrectly. A hospital-based radiologist who incorrectly omits modifier 26 on CMS-1500 claims effectively bills for services the hospital is also billing on UB-04, triggering duplicate billing audits and overpayment demands that can span multiple years of claims history.
Beyond modifier management, radiology billing must navigate the National Correct Coding Initiative (NCCI) bundling edits, which govern when guidance codes can be billed alongside procedural codes; ACR appropriateness criteria documentation requirements for advanced imaging; prior authorization workflows for CT, MRI, and PET scans; and RVU-based reimbursement optimization across the Medicare Physician Fee Schedule. Each imaging modality adds its own layer of specialty-specific rules — interventional radiology alone combines surgical procedure coding with radiology supervision codes and catheter placement hierarchies.
The result is a specialty where billing errors are both common and expensive. Healix RCM's radiology billing team trains exclusively on radiology revenue cycle — and the results reflect it.

Modifier Strategy
Mastering Radiology Modifiers — Where Most Practices Lose Revenue
Modifier errors in radiology are not minor billing mistakes — they are audit triggers and revenue leaks. Getting them right requires deep knowledge of ownership structure, facility type, and payer-specific rules.
Appended when the radiologist provides only the interpretation and written report — not the equipment or technical staff. Used when the radiologist does not own the imaging equipment.
Appended to claim the equipment operation, imaging staff, facility overhead, and supplies — but not the physician interpretation. Billed by the facility or the entity owning the equipment.
When a radiologist both performs and interprets the study using equipment they own, no modifier is needed. The global fee covers both technical and professional components.
GC indicates a service performed in part by a resident under the supervision of a teaching physician. GE indicates the teaching physician was not present but the service met the primary care exception.
Indicates that a procedure or service is distinct and separate from other services performed on the same day. Used to bypass NCCI bundling edits when two codes are legitimately billed together.
Required when billing bilateral services separately or when the payer requires laterality documentation for extremity or paired-organ studies.
Our Process
Our Radiology Revenue Cycle — From Order to Payment
A six-step workflow engineered specifically for radiology revenue cycles — from eligibility verification before imaging to denial recovery after adjudication.
Insurance Verification & Authorization
Same DayEvery scheduled study triggers real-time insurance verification and authorization confirmation. We confirm active coverage, radiology benefits, and whether the specific modality and CPT code require prior authorization before the patient is imaged.
Charge Capture & CPT Assignment
Same DayRadiologist interpretations and technologist reports feed directly into our charge capture workflow. Our certified radiology coders assign precise CPT codes, ICD-10 diagnoses, and the correct modifier set based on ownership structure, facility type, and payer-specific rules.
Prior Authorization Management
1–3 DaysAdvanced imaging — CT, MRI, PET, and nuclear medicine — requires prior authorization from most commercial payers. We submit PA requests with clinical documentation, ACR appropriateness criteria, and referring physician notes to maximize first-pass approval rates.
Claims Scrubbing & Electronic Submission
24 HoursClaims undergo multi-layer scrubbing against Medicare Physician Fee Schedule edits, NCCI bundling rules, and payer-specific claim requirements before submission. Clean claims are transmitted electronically within 24 hours of final report sign-off.
Payment Posting & Reconciliation
2 Business DaysERA-based auto-posting handles the majority of remittance. Manual EOB processing captures paper check payments and edge cases. Every payment is reconciled against expected reimbursement rates to identify underpayments before they are accepted.
Denial Management & Appeals
48 HoursAll denied claims are triaged by denial reason within 48 hours of receipt. Our radiology billing specialists file corrected claims, first-level appeals, and escalated appeals with clinical documentation and peer-reviewed literature support where required.
Denial Prevention

FAQ
Radiology Billing Questions Answered
QWhat is the difference between billing modifier 26 vs. TC in radiology?
Modifier 26 (Professional Component) is appended by the radiologist billing only for their interpretation and written report. Modifier TC (Technical Component) is appended by the entity billing for the equipment operation, imaging staff, and facility overhead. When the same entity provides both, no modifier is used and the global fee is billed. Incorrect modifier assignment is the most audited issue in radiology billing and can result in overpayment demands or significant underpayment.
QWhich radiology CPT codes require prior authorization?
Most major commercial payers require prior authorization for CT scans (70450–74250), MRI studies (70540–73723), PET scans (78816), and nuclear medicine procedures (78012–78999). Medicare does not require PA for diagnostic radiology, but commercial payers including UnitedHealthcare, Aetna, Cigna, and BCBS have robust PA requirements for advanced imaging. Failure to obtain PA before imaging is the leading cause of claim denial for high-value radiology services.
QHow does radiology billing differ for hospital-based vs. freestanding practices?
Hospital-based radiology groups typically bill only the professional component (modifier 26) on a CMS-1500, while the hospital facility bills the technical component on a UB-04. Freestanding radiology practices that own their equipment may bill the global fee. Teleradiologists exclusively bill modifier 26 for all interpretations regardless of where the patient is located. Each model has distinct enrollment, contracting, and billing requirements.
QWhat is NCCI and how does it affect radiology claims?
The National Correct Coding Initiative (NCCI) is CMS's set of claim edits that prevent improper payment for services that should be bundled. In radiology, the most common NCCI edits involve guidance codes (ultrasound guidance 76942, fluoroscopic guidance 77001) being bundled with related procedural codes. Modifier 59 or X-modifiers can bypass certain NCCI edits, but only when documentation supports the distinct nature of each service. Incorrect bundling unbundling is an OIG audit target.
QHow is RVU-based reimbursement calculated for radiology?
Medicare reimbursement is calculated by multiplying the total RVUs (work RVU + practice expense RVU + malpractice RVU) by the Medicare Conversion Factor (approximately $33.89 for 2025). RVUs for radiology are published in the Medicare Physician Fee Schedule (MPFS). When billing modifier 26, only the work RVU and professional practice expense apply. Understanding RVU components helps identify underpayment by commercial payers with contracts based on a percentage of Medicare rates.
QDo you handle billing for interventional radiology (IR) procedures?
Yes. Interventional radiology billing is among the most complex in medicine, combining radiology guidance codes with surgical procedure codes across multiple CPT code sections. Our IR billing specialists are trained on S&I (supervision and interpretation) code pairing, catheter placement hierarchy, embolization coding, and the bundling rules that govern IR procedures. We also manage facility billing coordination for hospital-based IR suites.
QCan you help recover radiology claims that were previously denied or written off?
Absolutely. We conduct a structured AR recovery analysis to identify claims within timely filing and appeal deadlines. For Medicare, first-level redetermination must be filed within 120 days of denial; ALJ hearings are available for claims over $180. For commercial payers, most allow 60–180 days for first-level appeals. We recover denied claims through corrected claim submissions, peer-to-peer physician reviews, and formal written appeals with clinical evidence.
QWhat radiology billing software and EHR systems do you support?
Our team works within your existing system — we do not require platform migration. We support all major radiology information systems (RIS) and practice management platforms including Merge RIS, Intelerad, PowerScribe, Ambra Health, Epic Radiant, and Meditech. We also integrate with teleradiology workflow tools and PACS for seamless charge capture and reporting.
