Interventional Radiology Billing Services
An interventional radiology case can carry five separate pieces of billable work: vascular access, selective catheter placement, the intervention itself, radiological supervision and interpretation (S&I), and imaging guidance. Some of those are bundled into the procedure code and some are not, depending on the code family. Qualigenix codes IR cases from the dictated procedure report, vessel by vessel, so each separately payable component is billed and nothing bundled is billed twice.
What Interventional Radiology Billing Takes
Interventional radiology billing takes coding each catheter placement, intervention, S&I, and imaging guidance service according to its code family's bundling rules, assigning the correct site of service (hospital, ASC, or office-based lab), and obtaining prior authorization for embolization, ablation, vein procedures, and device implants. Qualigenix's coders bill IR practices and hospital IR departments with a 98.2% first-pass clean claim rate on first submission. Start with a free billing audit at 786-259-0231.
01
Catheter, S&I, and Guidance Coding
Selective catheter placement is coded to the highest order reached in each vascular family, using 36215–36218 above the diaphragm and 36245–36248 in the abdomen, pelvis, and legs. Many newer IR codes, including embolization (37241–37244), image-guided fluid drainage (49405–49407), and fine needle aspiration (10005–10012), already include imaging guidance and S&I. Older code pairs still bill the procedure and the S&I separately. Applying the wrong rule either loses a payable line or creates an NCCI denial.
02
Procedure and Device Prior Auth
Commercial and Medicare Advantage plans often require approval for uterine fibroid and prostate artery embolization, tumor ablation, and high-cost devices. Traditional Medicare also requires prior authorization for vein ablation performed in hospital outpatient departments, under the OPD prior authorization program that added it in July 2023.
03
Peripheral Territory Coding
Lower-extremity revascularization codes are assigned by territory (iliac, femoral/popliteal, and tibial/peroneal) and by the most intensive service in each vessel, following the hierarchy of angioplasty, atherectomy, stent, and stent with atherectomy. Coding each device used instead of the highest service per vessel, or missing a second vessel in the same territory, changes payment.
04
Hospital, ASC, and OBL Billing
In a hospital or ASC, the radiologist bills the professional component with modifier 26 and the facility bills the technical side. In an office-based lab, the practice bills globally and carries the cost of the supplies and devices. Place of service has to match: 19 or 22 for hospital outpatient, 24 for an ASC, and 11 for an office.
05
Pre-Case Coverage Checks
Elective procedures such as fibroid embolization and varicose vein treatment, and oncologic procedures such as Y-90 radioembolization, carry payer coverage criteria that need to be checked before the case is scheduled, not after.
06
Vessel-Level Documentation
The report needs to name each vessel catheterized, the order of selectivity, the lesion treated, the device used, and the laterality. Diagnostic angiography on the same day as an intervention is billable only when no prior study is available, the prior study is inadequate, or the patient's condition has changed, and the note has to say which.
07
Recurring Denials
The recurring IR denials come from NCCI edits on bundled guidance and S&I, missing RT and LT modifiers, diagnostic angiography billed without the documentation that supports it, and payment reductions when several imaging procedures are performed in one session.
08
Medicare OPD and Order Rules
Beyond OPD prior authorization, Medicare requires diagnostic imaging to be ordered by the treating practitioner (42 CFR 410.32) and performed under the supervision level CMS assigns to each code. Device and supply codes have to match what the procedure report says was used.
How Qualigenix Turns IR Procedure Notes Into Clean Claims
Qualigenix turns IR procedure notes into clean claims by coding from the final dictated report, vessel by vessel, and checking each line against NCCI edits before submission.
Vessel-by-Vessel Coding
Coders map every catheter placement, intervention, and imaging service in the report to its code, then apply the bundling rule for that code family.
Procedure-Matched Auth
Each authorization request includes the planned procedure codes, the device, and the clinical criteria the payer requires. We check the approval again if the plan changes on the table.
Territory and Hierarchy Checks
We confirm one code per vessel at the highest service performed and capture additional vessels in each territory.
Network
We set global or professional-only billing, the place-of-service code, and the device billing by setting for every case.
Pre-Scheduling Coverage Checks
We check benefits and payer coverage criteria for elective and oncologic procedures before scheduling.
Report Review
When a report is missing a vessel name, order of selectivity, laterality, or the reason for same-day angiography, we send it back to the radiologist before billing.
Denial Appeals
Our denial team overturns 79% of the denials it works, with an average appeal turnaround under 9 days. Appeals cite the CPT rule or NCCI policy that supports the billed line.
NCCI Compliance Monitoring
We audit IR claims each month against current NCCI edits and Medicare contractor policies for peripheral vascular and venous procedures.
CASE STUDY 01
How a 3-provider podiatry group cleared $214K in aged A/R
THE SITUATION
A 3-provider podiatry group with roughly 60% Medicare payer mix carried $412,000 in A/R, 38% of it past 120 days. Routine foot care claims (11720, 11721, 11055–11057) had stalled on inconsistent Q7/Q8/Q9 modifiers and class-finding documentation, so payers held or partially paid and nobody worked the remainder. Medicare crossover to secondaries was not being posted, and small patient balances were written off.
WHAT QUALIGENIX DID
We ran a full A/R aging segmentation, worked claims by payer and denial reason rather than by date, rebilled the stalled routine-care claims with corrected modifiers, and reactivated secondary and crossover billing.

How a solo podiatrist lifted first-pass acceptance to 96%
THE SITUATION
A solo podiatrist coding 320 encounters a month was stuck at 82% first-pass acceptance. Routine foot care went out without the systemic-condition diagnosis pairing and class findings Medicare requires, so it read as non-covered. Wound debridement was coded to the wrong depth (11042 for skin and subcutaneous where the note supported 11043 for muscle and fascia). Same-day E/M with a procedure went out without modifier 25 and got bundled.
WHAT QUALIGENIX DID
We rebuilt the coding workflow: diagnosis-to-CPT pairing rules for at-risk foot care, correct Q-modifier logic, depth-based debridement coding tied to the operative note, and disciplined use of modifiers 25 and 59/XS.

How a 2-location podiatry practice cut its denial rate by two-thirds
THE SITUATION
A 2-location podiatry practice sat at a 19% denial rate, mostly Medicare routine-foot-care and nail-debridement rejections. The denials clustered in three buckets: medical-necessity rejections on routine foot care (missing qualifying diagnosis and class findings), frequency-edit denials on nail debridement billed inside the 60-day window, and missing Q modifiers that flagged services as non-covered.
WHAT QUALIGENIX DID
We built a front-end denial-prevention layer, checking eligibility and coverage against payer LCDs before claims went out, plus a structured appeal workflow with documentation templates mapped to each denial reason.

IR Coding by Procedure Family
Qualigenix codes interventional radiology by procedure family, because each family bundles guidance and catheter work differently.
Angiography and Catheterization
Codes: 36200–36248, 75600–75893. Nonselective and selective catheter placement by vascular family and order, with the matching angiography S&I codes where they are reported separately.

QUESTIONS BUYERS ASK
Qualigenix prices interventional radiology billing after reviewing your case volume, settings, payer mix, and the services you want to hand over. Most IR groups start with a free billing audit so the quote reflects real numbers.
We code each vascular family to the highest order of selectivity reached, using 36215–36218 above the diaphragm and 36245–36248 below it, and add codes for additional vessels in the same family where CPT allows.
We check every claim against current NCCI edits and the bundling rules for each IR code family before it is sent, and we audit IR claims every month. A free audit shows where your current claims conflict with NCCI edits.
Yes. We work IR claim backlogs by denial reason and timely-filing limit, starting with the highest-value cases. A free AR review shows how much is still recoverable.
Commercial and Medicare Advantage plans commonly require approval for embolization, tumor ablation, vein procedures, and high-cost devices. Traditional Medicare requires prior authorization for vein ablation in hospital outpatient departments. How do you code selective catheters?
Yes. Office-based lab cases are billed globally with place of service 11, while hospital and ASC cases are billed as the professional component with modifier 26 and the facility's place-of-service code.
Qualigenix works across 133 EMR/EHR platforms, including radiology information systems. We confirm access to your RIS and EHR during the free billing audit.
Qualigenix's average onboarding time is 6 days. That covers system access, payer enrollment checks, and coder assignment before we take over claim submission.
