CCSD code L3380 – Reinforcement of cerebral artery aneurysm

Key takeaways

CCSD code L3380 covers reinforcement (wrapping) of a cerebral artery aneurysm. Clipping (L3320) and endovascular treatment are billed under other CCSD codes.

L3380 sits in Chapter 2 of the CCSD schedule, section 2.5 Vessels, and UK private medical insurers use it to pay surgeons and anaesthetists.

I67.1 (cerebral aneurysm, nonruptured) and the I60 subarachnoid haemorrhage codes are the usual ICD-10 pairings for an L3380 claim.

UK private medical insurers commonly require pre-authorisation for L3380. A missing authorisation number and a thin operative note are the usual causes of declined claims.

Pabau, the practice software we build, sends CCSD invoices through Healthcode and tracks their status, using the codes your team records.

CCSD code L3380: Definition and clinical scope

CCSD code L3380 is the UK private-insurer code for reinforcement of aneurysm of cerebral artery. It covers open wrapping of an intracranial aneurysm through a craniotomy. The surgeon wraps the aneurysm with muslin, gauze or synthetic mesh when clipping is unsafe or impossible.

The L prefix comes from the arteries and veins chapter of OPCS-4, the classification CCSD codes are built on. CCSD files L3380 under section 2.5 with the other open cerebrovascular procedures. CCSD has no modifiers or sub-codes for side or vessel. The operative note and the ICD-10 code carry those details instead.

Neighbouring brain and cranium procedures each have their own entry among our private practice CCSD codes.

What reinforcement of a cerebral artery aneurysm involves

Reinforcement is a wrapping technique for an intracranial aneurysm that cannot be clipped. The neurosurgeon performs a craniotomy, usually a pterional or frontal approach, to expose the aneurysm.

A sheet of muslin, gauze or synthetic mesh then goes around the dome and neck. The wrap supports the weakened arterial wall and reduces the stress that leads to rupture.

The technique differs from the two definitive treatments. Clipping places a titanium clip across the aneurysm neck and excludes it from the circulation. Endovascular coiling fills the sac with platinum coils delivered through a catheter.

Reinforcement leaves the aneurysm open to blood flow but mechanically supported. Its long-term rupture risk differs from both definitive techniques. The operative note must state which technique was used, so the insurer can match it to L3380 rather than a clipping or endovascular code.

Key steps documented in the operative report

1. Craniotomy approach: type and side (pterional, frontal or other).
2. Exposure: identification of the affected cerebral artery and the aneurysm dome.
3. Clipping assessment: the intraoperative finding that clip ligation was not feasible.
4. Wrapping: the material used (muslin, gauze or mesh) and how it was applied.
5. Closure: confirmation of aneurysm coverage and haemostasis before closing.

Clinical indications: When is reinforcement performed?

Neurosurgeons choose reinforcement when they cannot safely exclude the aneurysm from the circulation. UK private insurers expect the clinical supporting letter and the operative note to name the specific indication.

• Fusiform or wide-neck aneurysm: the geometry prevents clip placement without compromising the parent artery.
• Calcified or atherosclerotic neck: the vessel wall will not tolerate clip pressure.
• High surgical risk: comorbidities make a prolonged procedure unsafe, and wrapping is quicker than clipping.
• Incidental aneurysm: the surgeon finds it during surgery for another lesion, with too little access for definitive treatment.
• Incomplete clipping: a residual dome after a failed clip attempt is wrapped as a protective measure.
• After subarachnoid haemorrhage (SAH): wrapping gives temporary protection against a rebleed while the patient stabilises.

A claim that says only “reinforcement performed”, without the anatomical or clinical reason, invites a query from the insurer.

ICD-10 diagnosis codes used with L3380

Every L3380 claim needs a paired ICD-10 diagnosis code, and UK private insurers use WHO ICD-10. Check each descriptor in the WHO ICD-10 browser. Insurers may query or decline a claim where the diagnosis does not support the procedure.

The presenting condition decides the principal diagnosis. After an emergency admission for rupture, an I60 code usually leads. For elective reinforcement of an unruptured aneurysm, I67.1 is the principal diagnosis. Confirm the sequence with the operating neurosurgeon before you submit the invoice.

The diagram below shows how the technique and the rupture status together set both codes on the claim.

Related CCSD codes and how they differ from L3380

Section 2.5 of the CCSD schedule groups L3380 with the other open procedures on brain vessels. The Bupa CCSD codes guide explains how CCSD codes work and how to look them up.

The CCSD schedule lists unacceptable combinations for each code. Check the L3380 entry before you add clipping, craniotomy or dural repair lines to the same claim. The CCSD code A0260 entry, for example, lists L3380 as an unacceptable combination.

Where one aneurysm is clipped and a separate aneurysm is wrapped in the same session, the operative note must describe each one. Ask the insurer at pre-authorisation how it wants that session claimed.

Pre-authorisation for CCSD code L3380 with UK private insurers

UK private medical insurers commonly require pre-authorisation before a planned L3380 procedure. That includes Bupa, AXA Health, Vitality Health, Aviva, WPA, Allianz Care and H3 Insurance. Policies differ by insurer and by the patient’s cover, so check the policy before booking theatre.

The pre-authorisation request for L3380 generally includes these items:

1. Clinical supporting letter: the neurosurgeon names the procedure using the L3380 descriptor, the affected vessel and the indication. The letter also explains why clipping or endovascular treatment is not suitable.
2. Imaging reports: CT angiography, MR angiography or digital subtraction angiography (DSA) confirming the aneurysm and its anatomy.
3. Procedure and diagnosis codes: L3380 with the ICD-10 code you intend to claim, either I67.1 or the relevant I60 code.
4. Hospital admission: the hospital stay and any critical care are authorised and invoiced by the hospital, not by the surgeon.
5. Written authorisation: record the authorisation number and the approved procedure codes before theatre.

Keep each authorisation number on the patient record next to the theatre booking, so the invoice can carry it. Our medical billing compliance guide covers the documentation standards that reduce claim risk.

Documentation requirements to support an L3380 claim

UK private insurers may ask for the operative note to validate an L3380 claim, especially given its value. Have complete documentation ready before you submit the invoice, and keep it for insurer audit.

Operative note elements

• Patient identifiers and the date of surgery.
• Pre-operative diagnosis with the affected vessel specified, for example a right middle cerebral artery aneurysm.
• Procedure performed: “Reinforcement of aneurysm of cerebral artery”, using the CCSD descriptor verbatim.
• Craniotomy approach: type, side and exposure technique.
• Aneurysm description: location, size, morphology (fusiform or saccular) and ruptured or unruptured status.
• Reason clipping was not performed: the specific anatomical or clinical rationale.
• Wrapping material: muslin, gauze or surgical mesh, and how it was applied.
• Imaging: the CT angiography, MR angiography or DSA findings that guided the procedure.
• Post-procedure status: haemostasis and the immediate neurological observations.
• Surgeon attestation with the consultant’s name and GMC number.
• Authorisation number from the patient’s insurer.

Anaesthetist, hospital and imaging charges alongside L3380

UK insurer fee schedules list a specialist fee and a separate anaesthetist fee against each CCSD code. The consultant anaesthetist invoices the insurer for L3380 under their own name and provider number. The neurosurgeon does not include the anaesthetic on their invoice.

• Anaesthetist: invoices separately against the same CCSD code, under the anaesthetist fee in the insurer’s schedule.
• Hospital: invoices theatre, ward and critical care stays under its own agreement with the insurer.
• Imaging: angiography performed during or after surgery is billed by the radiology provider under its own codes.

Why L3380 claims get declined and how to fix them

Most declined L3380 claims trace back to a small set of avoidable problems, each with a fix to make before resubmission. Claims management software that keeps codes and authorisation numbers on the patient record makes each check quicker.

How Pabau keeps L3380 claims and authorisations on one record

Neurosurgical billing teams often hold the authorisation letter, the operative note and the invoice in separate places. When one reference goes missing, the claim stalls while someone chases it.

In Pabau, the codes, authorisation number and clinical notes your team records sit on the patient’s record. Its claims management sends the invoice to the insurer through Healthcode and shows each claim’s status, so a declined claim surfaces quickly.

Pabau does not choose codes or obtain authorisations. Your neurosurgeon and billing team make those decisions, and Pabau carries their work through to a submitted, tracked claim.

Keep CCSD claims and their paperwork together

Pabau sends CCSD invoices to UK private insurers through Healthcode and tracks their status. Codes, authorisation numbers and operative notes stay on one patient record, so billing staff spend less time chasing missing details.

Conclusion

CCSD code L3380 pays for one specific choice in theatre: wrapping an aneurysm that the surgeon could not clip. The claim stands or falls on whether the paperwork shows that choice.

Pair it with I67.1 or the right I60 code, and keep unacceptable combinations off the claim. Then make sure the authorisation number and an operative note explaining why clipping was not possible travel with the invoice.

Those checks take minutes before submission, while a declined high-value claim can take weeks to reverse. Book a demo to see how Pabau keeps CCSD codes, authorisation numbers and claim follow-up on one patient record.
