CCSD Code XR306: Endovascular Treatment of Cerebral Aneurysm

Key Takeaways

CCSD code XR306 covers endovascular treatment of cerebral aneurysm, including coil embolisation and flow diversion techniques.

Always pair XR306 with the correct ICD-10 code: I67.1 (cerebral aneurysm, nonruptured) for elective cases or I60 (subarachnoid haemorrhage) for ruptured presentations.

Pre-authorisation is required by major UK private insurers before performing XR306; verify requirements with each insurer individually.

Device costs – coils, flow diverters, stents – may be billed separately from the XR306 procedure fee; confirm passthrough billing rules with each insurer.

Submit XR306 claims via Healthcode using your pre-authorisation number, consultant episode reference, and full procedural documentation.

Endovascular treatment of cerebral aneurysm is one of the most technically demanding procedures in interventional neuroradiology – and billing it correctly through UK private insurers is equally precise work. CCSD code XR306 endovascular treatment cerebral aneurysm is the designated billing code for these procedures under the Clinical Coding and Schedule Development (CCSD) framework, covering coil embolisation, flow diversion, and related endovascular techniques performed in the private sector.

This guide is written for interventional radiologists, neuroradiologists, neurosurgeons, and practice managers billing through insurers such as Bupa, AXA Health, Vitality, and Aviva. It covers the procedure scope of XR306, supporting and add-on codes, ICD-10 diagnosis code pairings, pre-authorisation workflows, documentation requirements, and Healthcode submission guidance. Fee amounts are not stated here – they vary by insurer, year, and individual policy, and should always be verified directly against the relevant insurer’s current schedule.

CCSD Code XR306 Endovascular Treatment Cerebral Aneurysm: Procedure Overview

XR306 sits within the interventional radiology and neuroradiology section of the CCSD schedule of procedures, which is maintained by the Clinical Coding and Schedule Development Group. The code covers the endovascular occlusion of a cerebral aneurysm, performed via intra-arterial access under fluoroscopic or digital subtraction angiography (DSA) guidance. Procedures captured under XR306 include standard coil embolisation, stent-assisted coiling, balloon-assisted coiling, and flow diversion using devices such as the Pipeline Embolisation Device (PED).

The procedure is distinct from open surgical clipping, which carries a separate CCSD code. When a patient undergoes both diagnostic cerebral angiography and endovascular treatment in the same episode, the interventionist should review CCSD bundling rules, as the diagnostic imaging component may or may not be separately codeable depending on the insurer’s schedule and unbundling guidelines. Always verify against the current CCSD technical guidance before submitting combined claims.

CCSD Code XR306 and Coil Embolisation

Coil embolisation remains the most commonly performed technique captured by CCSD code XR306 endovascular treatment cerebral aneurysm. The procedure involves advancing a microcatheter into the aneurysm sac under DSA guidance, then deploying platinum coils until the aneurysm is occluded. The British Society of Interventional Radiology (BSIR) recognises coiling as the preferred approach for most intracranial aneurysms, consistent with evidence from the International Subarachnoid Aneurysm Trial (ISAT). In private practice, this technical complexity is reflected in XR306 being categorised as a high-value interventional procedure requiring documented pre-authorisation from the insurer before the procedure date.

For practice managers handling claims management for interventional radiology consultants, it is worth noting that coil type and quantity are typically documented separately from the procedure code. Some insurers allow passthrough billing for coil costs as implantable device items; others include device costs within the procedure fee. The distinction has a direct impact on how the invoice is structured.

Stent-Assisted and Balloon-Assisted Coiling

Wide-necked aneurysms may require stent-assisted or balloon-assisted coiling to prevent coil herniation into the parent vessel. These adjunctive techniques are performed as part of the same interventional episode and are generally subsumed within XR306 rather than coded separately. However, some insurers may permit a modifier or add-on code when a second interventional device is deployed alongside the primary coiling procedure. Confirm current policy with each insurer before assuming all components are included under a single XR306 line.

Flow Diversion Techniques

Flow diversion – most commonly using the Pipeline Embolisation Device – redirects blood flow away from the aneurysm sac using a mesh stent deployed across the aneurysm neck. This technique is typically used for large or giant aneurysms not amenable to conventional coiling. XR306 covers flow diversion as an endovascular cerebrovascular procedure; the device itself (the flow diverter) is a high-cost implantable item that may be eligible for separate implant passthrough billing. Because flow diverter costs can be substantial, clarifying implant reimbursement policy with Bupa, AXA Health, or the relevant insurer before the procedure date is a prerequisite of good private practice management.

CCSD Code XR306 Chart: Techniques, ICD-10 Pairings, and Key Documentation

The table below summarises the main clinical scenarios in which CCSD code XR306 endovascular treatment cerebral aneurysm is applied, the corresponding ICD-10 diagnosis codes, and the documentation elements that support each claim. Always verify against the current NHS Classifications Browser and your insurer’s schedule before submitting.

ICD-10 code accuracy is critical for claim adjudication. Using I67.1 (cerebral aneurysm, nonruptured) for an elective procedure and I60 (subarachnoid haemorrhage) for an emergency ruptured presentation ensures the diagnosis aligns with the clinical episode. Mispairing – for instance, submitting I67.1 on an emergency claim arising from subarachnoid haemorrhage – may trigger a query from the insurer or delay settlement. NHS Digital clinical coding guidance and the NHS Classifications Browser provide the authoritative UK reference for ICD-10 5th edition code definitions.

CCSD Code XR306: Clinical Indications and Technique Selection

From a billing perspective, understanding the clinical decision behind XR306 matters because insurers may request clinical justification when reviewing high-value claims. NICE guidance on cerebrovascular intervention, together with BSIR clinical standards, supports endovascular coiling as the preferred treatment for most intracranial aneurysms – particularly those in the posterior circulation, small aneurysms with a favourable neck ratio, and patients who are not suitable candidates for open surgery. This evidence base underpins the clinical necessity argument that practice managers may need to present during insurer queries.

The clinical decision between endovascular treatment and open surgical clipping (a separate CCSD code) is made by the treating neurovascular team based on aneurysm morphology, patient factors, and institutional expertise. Neither this guide nor the XR306 code itself prescribes which technique should be used – the CCSD code simply reflects what was performed. Consultants moving from NHS to private practice should be aware that private insurers may have their own clinical criteria for authorising XR306 procedures, separate from NHS commissioning policies.

ICD-10 Diagnosis Codes to Pair with CCSD Code XR306

Pairing the correct ICD-10 diagnosis code with XR306 is not a formality – it is a substantive billing requirement that affects claim adjudication. Two primary codes apply depending on the clinical presentation:

• I67.1 – Cerebral aneurysm, nonruptured: Used for elective endovascular treatment of an unruptured aneurysm. This is the most common pairing in planned private practice cases.
• I60 – Subarachnoid haemorrhage: Used when the procedure is performed in the context of a ruptured aneurysm with subarachnoid haemorrhage. The I60 category includes subcategories based on haemorrhage source (e.g. I60.0-I60.9) – select the most specific code that reflects the clinical record. Pabau’s blog on intracranial haemorrhage ICD-10 codes provides additional context on cerebrovascular haemorrhage coding.

Always confirm ICD-10 code selection against NHS Digital clinical coding guidelines and the current CCSD schedule notes. If the clinical record includes a secondary diagnosis – for instance, a comorbid condition that influenced the decision to use endovascular rather than surgical treatment – include it as a secondary code on the invoice where the insurer’s claim form supports multi-code submission.

Billing CCSD Code XR306: Supporting Codes and Bundling Rules

XR306 captures the primary endovascular procedure, but a complete neurovascular intervention typically involves several additional clinical components. Whether those components are separately billable – or bundled into the XR306 fee – depends on the insurer’s schedule and the CCSD technical rules. The CCSD Technical Guide sets out the core business rules for code bundling and unbundling; always use the current version.

CCSD Code XR306: Anaesthesia and DSA Add-Ons

Endovascular cerebral aneurysm treatment is performed under general anaesthesia in most UK private units. The anaesthetist bills their fee separately using the appropriate CCSD anaesthesia code – this is not included within XR306. Similarly, the neuroanaesthetic team’s assistant, where present, may bill separately if the insurer’s schedule recognises assistant surgeon fees for this procedure type.

Digital subtraction angiography (DSA) is integral to performing XR306 – the procedure cannot be carried out without fluoroscopic guidance. In most cases, DSA is considered part of the procedure and is not separately billable alongside XR306. However, if a diagnostic DSA was performed as a discrete prior episode to assess the aneurysm before a planned intervention, and was billed separately at that time, it may legitimately be coded as a distinct procedure. The key question is whether the imaging was diagnostic or interventional guidance – and whether the two episodes were clinically and temporally separate. Check Healix, Bupa, and AXA Health schedules individually, as their unbundling rules differ. The Healix fee schedule includes specific unbundling guidance for interventional radiology procedures.

Implant Passthrough Billing for XR306

The cost of embolic devices – platinum coils, flow diverters, stent-assisted coiling systems – represents a significant proportion of the total cost of an XR306 episode. Many UK private insurers operate an implant passthrough mechanism, allowing hospitals or procedure centres to invoice for device costs separately from the surgeon’s procedure fee. However, passthrough policies vary considerably:

• Bupa: Operates a recognised implant list with specific approval requirements. High-cost devices such as flow diverters may require a separate pre-authorisation before the device can be billed. Use the Bupa code search tool to confirm whether a device has a recognised CCSD or implant code and whether prior approval is required.
• AXA Health: Has its own implant and device approval process via its specialist forms portal. Confirm device eligibility before the procedure date.
• Vitality: Fee and device coverage should be checked via the Vitality fee finder before scheduling the procedure.
• Aviva and WPA: Device passthrough rules are outlined in their respective fee schedules. Contact the insurer’s provider services team for high-cost device approval.

The hospital or independent treatment centre typically handles device billing through their own invoicing channel, separate from the consultant’s fee claim. Practice managers working within independent practice should clarify billing responsibility – consultant versus hospital – before the episode begins. Good private practice billing governance means resolving these questions at the point of booking, not at the point of invoice.

CCSD Code XR306: Pre-Authorisation and Insurer Requirements

Pre-authorisation is the single most important administrative step before performing any XR306 procedure in UK private practice. Without a valid pre-authorisation number from the insurer, the claim is almost certain to be rejected or subject to substantial delay. Because XR306 is categorised as a high-cost interventional procedure across all major UK private insurer schedules, authorisation is required in advance – not applied for retrospectively. Emergency cases involving ruptured aneurysms may have a modified pathway, but even in urgent situations, notifying the insurer at the earliest opportunity and obtaining a retrospective authorisation reference is standard practice.

Bupa and AXA Health Requirements

Bupa requires a pre-authorisation number before any planned neurovascular intervention. The request is typically initiated by the referring consultant’s secretary or the patient’s GP, and must specify the procedure code (XR306), the proposed hospital or treatment centre, and the diagnosis (ICD-10 code). Bupa’s provider services team will assign a pre-authorisation number, which must appear on every invoice related to the episode – the consultant fee, the hospital fee, and any device or implant invoices. Pabau’s guide to Bupa CCSD codes provides a broader reference for Bupa billing workflows in UK private practice.

AXA Health operates a similar pre-authorisation model. The specialist must be recognised by AXA Health, and the procedure must be requested through AXA’s authorisation system before treatment. AXA may request supporting clinical information – imaging reports, MDT discussion notes, or NICE guideline references – particularly for high-cost interventional procedures such as flow diversion.

Consultant vs Hospital Fee Responsibilities

In UK private practice, the consultant’s fee and the hospital or facility fee are always invoiced separately. For XR306, the interventional radiologist or neurosurgeon bills their professional fee directly to the insurer under their GMC number and recognised consultant reference. The hospital or independent treatment centre invoices separately for theatre time, nursing care, anaesthetic support, imaging consumables, and device costs.

This dual billing structure means the total cost of an XR306 episode reaches the insurer through two separate channels. Practice managers overseeing private practice EHR and billing workflows should ensure both invoice streams reference the same pre-authorisation number and episode date. Discrepancies between the consultant’s and hospital’s claim references are a common source of query letters and delayed settlement.

Documentation Requirements for CCSD Code XR306

Thorough clinical documentation is both a patient safety requirement and the foundation of a defensible billing claim. For CCSD code XR306 endovascular treatment cerebral aneurysm, the documentation standard expected by UK private insurers mirrors what the General Medical Council (GMC) and the Royal College of Radiologists (RCR) require for any complex interventional procedure.

Clinical Record Requirements for CCSD Code XR306

The minimum documentation set for an XR306 claim should include:

1. Referral letter and clinical indication: Confirms the clinical necessity for intervention and the referring physician’s identification details.
2. Pre-procedure imaging report: DSA or MRA/CTA report documenting aneurysm location, size, morphology, and neck characteristics. This supports the choice of technique and the ICD-10 code selection.
3. Pre-authorisation number: Issued by the insurer before the procedure date. Must be recorded in the patient’s billing file.
4. Operative / procedure note: Completed by the interventionist, describing vascular access, catheter navigation, device deployment, completion angiography findings, and any complications. This is the primary document against which the XR306 code is justified.
5. Anaesthetic record: Documents the anaesthetic episode, which supports the separate anaesthesia fee claim.
6. Implant records: Device serial numbers, batch codes, and quantities for all coils, stents, or flow diverters deployed. Required for implant passthrough billing and for patient safety traceability under Care Quality Commission (CQC) regulations.
7. Consent documentation: Signed informed consent covering the procedure, its risks, and the alternatives – including open surgical clipping.

Practices using digital consent and clinical forms can capture, store, and retrieve these documents within the patient record, which reduces the administrative overhead of responding to insurer queries. UK GDPR obligations under the Information Commissioner’s Office (ICO) apply to all patient billing records; for a structured compliance overview, the UK GDPR compliance checklist is a practical reference for private practice teams.

Healthcode Submission Guidance for XR306

Healthcode is the standard electronic billing and submission platform used by the majority of UK private hospitals and independent consultants to submit claims to private insurers. For XR306, the submission workflow through Healthcode follows the standard CCSD claim structure:

1. Log in to Healthcode and create a new claim for the relevant insurer (Bupa, AXA Health, Vitality, Aviva, Cigna, WPA, or other).
2. Enter the patient’s membership number and policy reference as provided on the insurer’s authorisation confirmation.
3. Enter the pre-authorisation number issued for the XR306 episode.
4. Select CCSD code XR306 as the primary procedure code.
5. Attach the ICD-10 diagnosis code (I67.1 or I60 as appropriate).
6. Include any supporting or add-on codes for separately billable components (anaesthesia, assistant surgeon fee, if applicable per insurer schedule).
7. Submit the claim and retain the Healthcode submission reference for your records.

CQC-registered facilities are required to maintain records of all implantable devices used in procedures, which creates a natural crossover between clinical governance and billing documentation. Practice managers overseeing compliance for neurovascular interventions should be familiar with both the CQC’s regulatory role and the compliance management systems available to private practices. Ensuring CQC registration requirements are met for facilities performing endovascular neurovascular procedures is a prerequisite before billing XR306 at all.

Conclusion

CCSD code XR306 endovascular treatment cerebral aneurysm demands the same precision in billing as it does in the angiography suite. The code covers a technically complex interventional episode – from standard coil embolisation to flow diversion – and billing it correctly requires accurate ICD-10 code pairing, verified pre-authorisation from the insurer, and complete procedural documentation before submission through Healthcode.

Fee amounts are not fixed in this guide because they vary by insurer, year, and individual policy tier. Always verify current XR306 fee values directly against your insurer’s schedule – Bupa, AXA Health, Vitality, Aviva, WPA, Cigna, and Healix each publish their own schedule. The CCSD Technical Guide provides the authoritative business rules for code bundling and add-on billing. When in doubt, contact the insurer’s provider services team before the procedure date rather than after the invoice is rejected.
