Why the 2026 Changes Matter
Interventional radiology coding rarely sits still for long, but the 2026 revision to CPT 61624 and 61626 is bigger than a routine wording update. It changes what the code itself already pays for. Effective January 1, 2026, both codes were rewritten to fold radiological supervision and interpretation, intraprocedural roadmapping, and the imaging guidance needed to complete the intervention directly into the base procedure.
That single change has ripple effects across claim preparation. Imaging codes that were once reported alongside 61624 and 61626 under certain circumstances — most notably CPT 75894 and 75898 — are no longer separately reportable with them. Billing teams that haven't updated their charge capture logic or claim-edit software are the ones most likely to see denials once the new rules take effect.
This guide breaks down the anatomical distinction between 61624 and 61626, walks through exactly what the 2026 revision bundled, explains the 75894/75898 exclusion in plain terms, and gives coding and billing staff a practical checklist for getting these claims right the first time.
Understanding CPT 61624 and CPT 61626
Both codes describe transcatheter permanent occlusion or embolization — stopping or blocking blood flow to a target vessel, often to control bleeding, treat a vascular malformation, or cut off blood supply to a tumor. The distinction between them comes down entirely to anatomical territory, not technique.
CPT 61624 applies when the embolization targets the central nervous system — intracranial vessels or the spinal cord. CPT 61626 applies when the target lies outside the CNS, in the head or neck, typically involving extracranial brachiocephalic branch vessels. A procedure can only be reported under one of these two codes for a given target; the anatomy documented in the operative note is what drives the selection.
Coding Consideration | CPT 61624 | CPT 61626 |
Anatomical scope | Central nervous system | Non-CNS head and neck |
Relevant regions | Intracranial vessels, spinal cord | Extracranial brachiocephalic branches |
Typical use case | Intracranial aneurysm, AVM, CNS tumor vascularity | Head/neck tumor, epistaxis, extracranial vascular lesion |
2026 imaging inclusion | RS&I, roadmapping, and procedural imaging guidance bundled | RS&I, roadmapping, and procedural imaging guidance bundled |
The practical takeaway: before assigning either code, confirm whether the treated vessel sits inside the CNS or outside it. That single anatomical fact — not the embolic material used, the catheter approach, or the clinical indication — determines which code applies.
What Changed in 2026?
Prior to 2026, imaging work performed during these embolization procedures was sometimes reported separately, depending on the specific services performed and payer policy. The 2026 CPT revision removed that variability by building the imaging components directly into 61624 and 61626.
Billing Component | Pre-2026 Approach | 2026 Approach |
Embolization procedure | Reported with 61624 or 61626 | Reported with 61624 or 61626 |
RS&I | Sometimes reported separately | Included in the code |
Intraprocedural roadmapping | Sometimes reported separately | Included in the code |
Imaging guidance to complete the intervention | Sometimes reported separately | Included in the code |
This bundling does not mean every imaging-adjacent service becomes unreportable. Work that falls outside the scope of completing the embolization itself — such as a medically necessary diagnostic angiogram performed through a separate access site and meeting applicable reporting criteria — may still have its own reporting pathway. The bundle applies specifically to the imaging that supports the embolization intervention described by 61624 and 61626.
CPT 75894 and 75898 — Understanding the New Bundling Rule
Compliance Reminder Per the AMA's November 2025 CPT Assistant guidance for the 2026 code set, CPT 61624 and 61626 should not be reported together with CPT 75894 (transcatheter therapy, embolization) or CPT 75898 (angiography through an existing catheter for follow-up study). No modifier is intended to override this exclusion. Claim-edit systems and charge masters should be updated to remove 75894/75898 from standard charge capture built around 61624 and 61626. |
Before 2026, 75894 and 75898 played a role in reporting the imaging supervision and follow-up angiography tied to embolization procedures. The 2026 revision absorbed that imaging work into 61624 and 61626 themselves, which is why the companion guidance explicitly instructs against reporting those two imaging codes alongside the revised embolization codes.
For billing teams, this means two concrete changes: first, charge tickets and EHR order sets built around the old code pairing need to be updated so 75894/75898 aren't automatically pulled in alongside 61624/61626. Second, claim-scrubbing software and payer-specific edits should be checked to confirm they reflect the 2026 exclusion rather than an outdated pre-2026 rule set.
CPT 61624 vs. 61626 — Avoiding Code Selection Mistakes
Most selection errors between these two codes trace back to one of two issues: the operative note doesn't clearly state whether the target vessel is intracranial/spinal (CNS) or extracranial (non-CNS), or the coder defaults to whichever code was used on a similar prior claim without re-checking the anatomy for this encounter.
• Confirm the vascular territory named in the operative report before assigning a code.
• Don't let the clinical indication alone drive code selection — tumor embolization, for example, can fall under either code depending on anatomical location.
• Treat each encounter independently; don't carry forward a prior claim's code without re-verifying the current documentation.
• When documentation is ambiguous about CNS versus non-CNS involvement, query the provider rather than guessing.
Documentation and Medical Necessity
Strong documentation protects both code selection accuracy and claim integrity. At minimum, the operative note should support:
• Clinical indication for the embolization
• Specific anatomical location and target vessel or vascular territory
• Whether the territory is CNS (intracranial/spinal) or non-CNS (head/neck extracranial)
• Percutaneous approach and access site used
• Embolization technique and materials, when applicable
• Procedural findings and outcome
• Confirmation that imaging guidance performed was part of completing the intervention, not a separately reportable diagnostic study
General documentation best practices — legible notes, timely completion, consistent terminology — support every claim. The CNS-versus-non-CNS distinction and the imaging-bundling language above are the two elements specific to 61624/61626 that deserve particular attention in 2026.
Common CPT 61624 and 61626 Billing Mistakes
Common Mistake | Why It Matters | Recommended Review |
Using a pre-2026 code description | May misrepresent what's bundled into the procedure | Confirm current CPT 2026 descriptor language |
Reporting 75894 or 75898 alongside 61624/61626 | Conflicts with the 2026 bundling instruction | Remove from standard charge capture and claim edits |
Confusing CNS and non-CNS territory | Leads to the wrong code being selected | Re-review the operative report's anatomical detail |
Relying on outdated payer edit files | Can create inconsistent claim scrubbing results | Update claim-edit logic to reflect 2026 CPT guidance |
Reporting imaging as separate without support | Creates compliance exposure if the imaging was part of the intervention | Validate against documentation before submission |
Medicare Reimbursement and Payer Considerations
Medicare payment for 61624 and 61626 is determined through the Medicare Physician Fee Schedule, which factors in relevant value units, geographic practice cost indices, and the site of service. Because these figures are updated annually and vary by locality, Sirius Solutions Global does not publish a universal reimbursement amount here — billing teams should verify current RVUs and payment amounts directly through CMS's fee schedule lookup tool for the applicable locality and setting.
Commercial payers are not required to mirror Medicare's bundling decisions on the same timeline, and some payer contracts carry their own coding edits. Verify individual payer policy for 61624 and 61626 rather than assuming Medicare's 2026 approach applies uniformly across all payers.
Practical Claim Preparation Checklist
☐ Confirm the correct 2026 CPT code (61624 or 61626) based on documented anatomy
☐ Verify the operative note supports CNS versus non-CNS territory clearly
☐ Remove 75894/75898 from charge capture tied to these procedures
☐ Confirm claim-edit software reflects the 2026 bundling instruction
☐ Check documentation for required procedural and imaging elements
☐ Verify applicable payer-specific requirements before submission
☐ Review remittance advice for denial patterns tied to outdated code pairings
How Better RCM Workflows Support Neurointerventional Practices
Coding accuracy is one part of a larger revenue cycle. Practices that update charge masters and claim edits promptly after a CPT revision tend to see fewer denials tied to outdated code pairings — and fewer downstream appeals. A disciplined workflow connects coding review, claim scrubbing, denial tracking, and payment reconciliation so that a change like the 2026 bundling rule gets reflected everywhere it needs to be, not just in the coding team's reference sheet.
Sirius Solutions Global works with interventional and neurointerventional practices on exactly this kind of workflow alignment — reviewing charge capture, coding accuracy, and claim-edit logic against current CPT guidance so that revenue cycle processes keep pace with coding changes rather than catching up after denials accumulate.
Frequently Asked Questions
What is CPT code 61624 used for?
CPT 61624 reports transcatheter permanent occlusion or embolization involving the central nervous system — intracranial vessels or the spinal cord.
What is the difference between CPT 61624 and 61626?
61624 covers CNS embolization (intracranial/spinal), while 61626 covers non-CNS head and neck embolization involving extracranial brachiocephalic branch vessels. The distinction is anatomical, not technique-based.
What changed for CPT 61624 and 61626 in 2026?
Effective January 1, 2026, both codes were revised to include radiological supervision and interpretation, intraprocedural roadmapping, and the imaging guidance needed to complete the intervention.
Are CPT 75894 and 75898 separately reportable with 61624 or 61626 in 2026?
No. AMA CPT Assistant guidance published in November 2025 for the 2026 code set states that 61624 and 61626 should not be reported together with 75894 or 75898.
Does CPT 61624 include imaging guidance?
Yes. As of the 2026 code set, imaging guidance necessary to complete the intervention is bundled into 61624 (and 61626), rather than reported separately.
What documentation should support neurointerventional embolization billing?
Clinical indication, specific anatomical/vascular territory, CNS versus non-CNS status, procedural approach, technique and materials used, and findings — documented clearly enough to support the code selected.
How should billing teams review Medicare reimbursement for these codes?
Check current RVUs and payment amounts through the CMS Medicare Physician Fee Schedule lookup tool for the applicable locality and site of service, since figures vary and update periodically.
