Oncology Billing Software That Integrates with Varian ARIA
Varian ARIA manages radiation oncology and medical oncology treatment records, Unlimited Integration syncs that data with Unlimited Financials so radiation fractions, infusion administrations, and treatment plans translate directly into specialty-validated charges, with drug waste and modifier logic applied automatically.
What changes with Varian ARIA
Without it
Radiation fraction billing complexity
Tracking delivered fractions against the treatment plan and translating that into accurate claims is labor-intensive when done manually.
Infusion waste tracking
Drug waste modifiers for infused agents documented in ARIA often require separate manual review for billing.
Treatment plan vs. claim drift
Changes to the treatment plan mid-course can create mismatches with what's billed if systems aren't synced.
With Unlimited Systems
ARIA treatment record sync
Radiation fractions and medical oncology administration records flow from ARIA into Unlimited Financials automatically.
Automated waste & modifier logic
Drug waste and JW/JZ modifiers apply automatically based on ARIA administration data.
Episode-based cycle recognition
Unlimited AI keeps multi-fraction radiation courses and infusion cycles billed consistently from start to finish.
What you get on day one
Radiation fraction charge capture
Each delivered fraction recorded in ARIA generates a specialty-validated charge automatically.
Medical oncology administration sync
Infusion and chemotherapy administration data from ARIA feeds charge entry with NDC and dosage detail.
Specialty modifier engine
Oncology-specific modifiers (59, 58, JW, JZ) apply automatically based on synced treatment data.
Audit trail to the treatment plan
Every charge links back to the ARIA treatment record that generated it, simplifying audits and appeals.
Frequently asked questions
Does this cover both radiation and medical oncology?
Yes. The ARIA integration supports both radiation therapy fraction billing and medical oncology infusion/chemotherapy charge capture.
How are drug waste modifiers handled for infusions?
Administered and wasted quantities from ARIA's medical oncology module drive automatic JW/JZ modifier application.
Can billing see the original treatment plan?
Yes, each generated charge retains a reference back to the ARIA treatment record for audit and appeal support.
