Radiology billing sits at the intersection of high-volume services, complex modifier rules, mandatory prior authorization, and intense payer scrutiny — and generic medical billing software was never built to handle it. The most costly radiology billing errors happen at the code level: missing modifier -TC or -26 on component claims, contrast protocol misclassification for CT and MRI, NCCI bundling violations, and expired prior authorization from Radiology Benefit Management (RBM) companies. MedCods was built specifically to eliminate all of these — with automatic TC/26 component detection, modality-specific CPT validation, RBM prior auth via FHIR API (eviCore, AIM Specialty Health, Carelon), and a 98.2% first-pass clean claim rate for radiology clients.

Radiology billing is uniquely complex because it requires capabilities that general-purpose billing platforms simply don’t carry. Three failure points account for the majority of imaging center revenue loss:
1
Every radiology claim must be correctly categorized as global (full service by one provider), technical component (-TC, covering equipment and technologist), or professional component (-26, covering the radiologist's interpretation). The payment split runs approximately 60% TC and 40% to the radiologist. Incorrect modifier usage — missing -TC, missing -26, using the global code when components should be split, or billing the wrong modifier in position 1 — triggers automatic denials or systematic underpayments. MedCods detects the PC/TC indicator for every CPT code and routes claims correctly, automatically, before submission.
2
85% of commercial payers and Medicare Advantage plans now require prior authorization for advanced imaging (CT, MRI, PET/CT, nuclear medicine) through Radiology Benefit Management companies — eviCore, AIM Specialty Health, and Carelon. Manual phone and fax submissions to RBM companies consume 2–3 hours of staff time per day and take 2–3 business days to resolve. MedCods replaces this entire process with FHIR-based API submission — auth requests triggered at order entry, confirmed in minutes, authorization numbers linked automatically to the associated claim.

CT codes split by contrast protocol: without contrast, with contrast, and with-and-without contrast — each a different CPT code. MRI codes require body region, laterality, and contrast status. A single contrast misclassification (billing 74177 instead of 74178 for a with-and-without study) costs the reimbursement difference and triggers a denial. MedCods validates contrast protocol at charge entry against the imaging order documentation, eliminating this category of error entirely.
MedCods carries the complete radiology CPT code set across all seven categories, pre-loaded with PC/TC indicators, contrast protocol rules, payer-specific coverage policies, and 2026 Medicare fee schedule rates. All modifiers are pre-mapped. All NCCI bundling edits are built in. No manual lookups required.

PC/TC indicator verified for every CPT code. TC and professional component claims routed automatically to facility and radiologist. Modifier sequencing (-TC or -26 in position 1) validated. Bilateral studies (-50) handled correctly.
CT contrast protocol (without/with/w&w) and MRI body region, laterality, and contrast status validated at charge entry. Prevents the most common CT/MRI coding errors that trigger systematic denials.
Denial heatmaps by modality, payer, and CPT code. CO-50, CO-16, CO-97, CO-4 most common in radiology — all addressed by pre-submission validation. AAPC-certified radiology coders handle complex appeals including RBM reconsideration via our denial management center.
FHIR-based API prior auth replaces phone and fax for all RBM companies. Triggered at order entry for CT, MRI, PET/CT, and nuclear medicine. Auth# linked to claim. Expired auth alerts fire before appointment. Integrated directly with insurance eligibility verification modules.
3M+ coding rules with dedicated radiology module: NCCI bundling edits, LCD medical necessity, Medicare 2026 fee schedule (+0.8% CF), modifier -59/-XU payer preference, and AI-assisted imaging CPT codes tracked by payer coverage. Powered by the core MAXIMUS AI Engine.
AAPC-certified specialist with radiology billing expertise: TC/26 disputes, RBM appeals, LCD medical necessity, interventional radiology coding, and No Surprises Act independent dispute resolution for out-of-network reads.
High-volume, high-prior-auth environments where TC billing dominates and RBM prior auth can consume hours of staff time daily. MedCods automates prior auth at order entry and validates every TC claim automatically — eliminating the two largest sources of imaging center revenue loss.
Professional component billing environments where -26 modifier accuracy and LCD medical necessity documentation are the primary denial drivers. MedCods validates both at charge entry and provides AAPC-certified coder review for complex CO-50 (medical necessity) denials.
Complex add-on codes, supervision and interpretation requirements, and bundling rules specific to IR procedures require a billing platform that understands how IR work is actually performed. MedCods carries all IR codes pre-loaded with payer-specific bundling rules and modifier guidance. Connects closely with our adjacent pathology billing solutions.
Multi-state billing, place-of-service distinctions for professional component claims, and state-specific payer requirements create complexity that standard billing software misses. MedCods handles the POS distinction automatically — professional component claims reflect where the procedure was performed, not where the radiologist reads — and supports multi-state credentialing.
Radiology billing is uniquely complex because it involves technical and professional component splitting (TC/-26), mandatory prior authorization through RBM companies (eviCore, AIM, Carelon), contrast-protocol-specific CPT coding for CT and MRI, NCCI bundling edits specific to imaging, and high-volume claim environments where a single systematic error costs thousands monthly. Generic billing software was not built to handle these rules automatically.
TC/26 billing separates a radiology service into two claims: the technical component (-TC), covering equipment and technologist costs, and the professional component (-26), covering the radiologist’s interpretation. The payment split runs ~60% TC and ~40% to the radiologist. MedCods automatically checks the PC/TC indicator for every CPT code and routes claims correctly — global, TC-only, or -26 only — with modifier sequencing validated automatically.
MedCods integrates with eviCore, AIM Specialty Health, and Carelon via FHIR-based API — replacing phone and fax. Prior auth requests for CT, MRI, PET/CT, and nuclear medicine are triggered automatically at order entry. Authorization is confirmed in minutes (vs 2–3 business days by phone), the auth# is linked directly to the associated claim, and expired auth alerts fire before the patient’s appointment.
MedCods supports the full radiology CPT range (70010–79999) across all seven categories: diagnostic radiology (X-ray, fluoroscopy), CT, MRI, ultrasound, mammography, nuclear medicine, and interventional radiology. Radiation oncology (77261–77799) and the 2026 AI-assisted imaging Category III codes (0691T–0710T) are also included. All codes carry PC/TC indicators, contrast protocol rules, and payer-specific coverage policies pre-loaded.
The top five radiology denial causes in 2026 are: (1) missing or expired RBM prior authorization (CO-197), (2) medical necessity failure — ICD-10 doesn’t support the imaging CPT code per LCD (CO-50), (3) contrast protocol misclassification (CO-16), (4) TC/26 modifier errors (CO-4), and (5) NCCI bundling violations (CO-97). MedCods prevents all five at charge entry through MAXIMUS AI validation.
Yes. For teleradiology, MedCods automatically handles the place-of-service distinction — professional component claims reflect where the procedure was performed, not where the radiologist reads. For interventional radiology, all IR codes are pre-loaded with payer-specific bundling rules, add-on code guidance, and supervision and interpretation requirements.
Most radiology practices are fully live within 5–7 business days. MedCods handles RIS/EHR integration (Epic Radiant, Cerner, Ambra, Intelerad, Sectra), payer enrollment verification, RBM API setup (eviCore, AIM, Carelon), and staff training. All radiology CPT code sets, modifier rules, and payer-specific prior auth workflows are pre-loaded — no manual configuration required.
Radiology revenue leaks from the same three places in every imaging center: TC/26 errors that go undetected for months, prior auth denials that compound daily, and contrast protocol coding mistakes that trigger systematic underpayments.
