Radiology billing hinges on the 26/TC component split, NCCI bundling of multiple studies, contrast pass-through capture, and repeat-study modifiers 76/77. Add medical-necessity gaps and facility-vs-freestanding misalignment, and general billers miss revenue on every study. MedFactor delivers radiology-specific RCM that protects every claim.

From diagnostic imaging to interventional procedures, we tailor billing to the coding rules of every radiology subspecialty.
CT, MRI, ultrasound, and X-ray with correct 26/TC component splits, contrast capture, and medical-necessity documentation.
Image-guided procedures with catheter and vascular coding, NCCI bundling, and facility/professional component accuracy.
MRI brain and spine, CT angiography, and advanced neuro studies with contrast and 26/TC split precision.
MRI and CT of joints and extremities with modifier 59 for distinct studies and repeat-study modifier 76/77 capture.
Mammography, breast ultrasound, and biopsy with bilateral modifier 50 and screening-to-diagnostic workflow capture.
High-volume stat imaging with after-hours coverage, repeat-study modifiers, and rapid-turnaround claim submission.
Every radiology study is either billed globally (one code, no modifier) or split into a professional component (modifier 26, physician interpretation) and a technical component (modifier TC, equipment and facility). Billing global where a split is required, or splitting where global is required, is the #1 source of radiology revenue leakage.
One imaging study, three billing scenarios. The right choice depends on who owns the equipment and who reads the study.
The practice owns the imaging equipment and the physician interprets the study in-house. One code is billed with no modifier, the practice captures both the professional and technical revenue.
The physician interprets a study performed at an outside or hospital facility. Only the professional component (modifier 26) is billed, the facility keeps the technical component.
The facility owns the equipment and acquires the images, and an independent physician reads elsewhere. Only the technical component (modifier TC) is billed by the facility.
Radiology billing is governed by 26/TC component splits, NCCI bundling, and contrast pass-through rules that general billing companies cannot navigate effectively.
Studies billed globally where the payer requires a 26/TC split, or split where global is required, losing the component revenue on every study.
Multiple related studies performed the same session denied as bundled when modifier 59 isn’t appended for genuinely distinct studies.
Low-osmolar contrast pass-through (Q9967) not billed per mL in non-facility settings, or double-billed where packaged into the study.
Repeat studies performed the same day denied without modifier 76 (same physician) or 77 (different physician).
Advanced imaging denied for medical-necessity gaps when the diagnosis doesn’t support the study level (e.g., MRI without vs. with contrast).
Facility and professional billing misaligned across hospital-based and freestanding imaging, causing duplicate or missed component claims.

Real results from radiology practices that partnered with MedFactor for specialty revenue cycle management.
A multi-modality imaging center was billing studies globally where payers required a 26/TC split and losing the professional component. MedFactor implemented payer-specific component billing, recovering substantial study revenue in eight months.
A CT-heavy practice was dropping low-osmolar contrast pass-through and letting distinct studies bundle without modifier 59. MedFactor implemented per-mL Q-code capture and modifier 59 logic, recovering contrast and distinct-study revenue.
A multi-site radiology group had facility and professional billing misaligned across hospital-based and freestanding locations. MedFactor unified component billing across sites, lifting net collections across the entire practice.
No matter where your radiology practice operates, our team understands the payer landscape and regulatory requirements in your region.
Payer-specific component billing rules applied correctly across Medicare, Medicaid, and commercial payers.
Facility and freestanding imaging billing aligned to the correct site-of-service component rules.
Low-osmolar contrast Q-code capture applied per payer policy across all 50 states.
Modifier 59 and X{E,S,P,U} applied per NCCI edits for distinct studies in every region.
Common questions from radiology practices considering MedFactor’s specialty RCM services.
Every imaging study has a professional component (modifier 26, the physician interpretation and report) and a technical component (modifier TC, the equipment, facility, and image acquisition). When the practice owns the equipment and the physician reads the study in-house, the global code is billed with no modifier. When a physician interprets a study performed at an outside or hospital facility, only the 26 is billed and the facility keeps the TC. When the facility owns the equipment and an independent physician reads elsewhere, only the TC is billed. We verify who owns the equipment and who interprets each study, then bill the correct global, 26, or TC configuration per payer rules.
A study is billed globally (one code, no modifier) when the same practice owns the imaging equipment and provides the physician interpretation. It is split when the equipment and the interpretation live in different entities, for example, a hospital owns the scanner and a radiology group reads the study, or an outside facility acquires the images and your physician interprets them. Medicare and many commercial payers require the split in those cases. Billing global where a split is required (or splitting where global is allowed) is the single largest radiology leakage point, so we confirm the ownership and reading arrangement per study before submission.
Contrast administration is usually packaged into the primary imaging code, but low-osmolar contrast may be billed separately using HCPCS Q-codes. Q9967 covers low-osmolar contrast material at 300-399 mg/mL iodine concentration, billed per milliliter administered. In non-facility settings (physician offices and freestanding imaging centers) the Q-code is typically paid separately under ASP methodology; in hospital outpatient settings it is generally packaged into the APC payment and reported for tracking only. We bill the Q-code per the exact mL recorded in the contrast log and apply packaged-contrast logic where separate payment isn’t allowed, so contrast is captured where the payer permits it and not double-billed where it isn’t.
The National Correct Coding Initiative (NCCI) bundles certain imaging studies when performed in the same session because they overlap clinically or anatomically. When the studies are genuinely distinct, different anatomic structures, separate encounters, or separate indications, modifier 59 (or the X{E,S,P,U} subset: XE separate encounter, XS separate structure, XP separate practitioner, XU unusual non-overlapping service) is appended to override the edit and pay both studies. We verify each edit pair before submission and append the correct distinct-service modifier only when the studies are truly distinct, preventing both bundling denials and inappropriate override denials.
When the same imaging study is repeated on the same day, modifier 76 (repeat procedure by the same physician) is appended if the same reader performs both studies, and modifier 77 (repeat procedure by another physician) is appended if a different reader performs the repeat. Without the correct repeat modifier, the second study is typically denied as a duplicate. We track repeat studies by date of service and reader and append 76 or 77 based on which physician performed the repeat, so same-day repeat imaging is paid rather than denied as a duplicate claim.
We integrate with all major radiology platforms including PACS and RIS systems, Epic, Cerner, Athenahealth, and leading practice management systems. Our team works with your imaging study detail, contrast logs, and reading reports so study-level data flows cleanly to correct claim submission, including the 26/TC component ownership, contrast per-mL volume, and modifier 59/76/77 detail that drives accurate radiology coding.
