CCSD Code L2360: Repair of Interrupted Aortic Arch

Key Takeaways

CCSD code L2360 covers the surgical repair of interrupted aortic arch in the UK private healthcare billing system.

Pre-authorisation from private insurers is typically required before submitting L2360 claims.

Co-coding for VSD repair, PDA ligation, and cardiopulmonary bypass is common and must be supported by clinical documentation.

Healthcode supports electronic submission of CCSD codes, including complex cardiothoracic procedures.

Accurate operative reports and discharge summaries are the foundation of a successful L2360 claim.

Introduction

CCSD code L2360 repair of interrupted aortic arch is one of the most complex procedures in the UK private healthcare billing system. Interrupted aortic arch is a rare but life-threatening congenital heart defect, and the surgical repair demands an equally precise approach to clinical coding and claim submission. For paediatric cardiothoracic teams and private practice billing administrators, getting L2360 right from the outset determines whether a claim clears first time or generates a time-consuming dispute with the insurer.

The CCSD Group maintains the Clinical Coding and Schedule Development schedule used by private insurers across the United Kingdom. Unlike NHS billing, which relies on Healthcare Resource Groups (HRGs) and OPCS-4 procedure codes, CCSD codes form the basis of every private medical insurance (PMI) invoice for hospital and specialist procedures. This article covers the clinical definition of L2360, documentation requirements, insurer-specific billing protocols, related codes, and practical guidance for submitting clean claims through Healthcode or direct insurer portals.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Clinical Definition

Interrupted aortic arch (IAA) is a congenital cardiac defect in which the aortic arch is discontinuous, meaning the descending aorta has no direct connection to the ascending aorta. Blood flow to the lower body depends entirely on the patent ductus arteriosus (PDA), which closes within days of birth without medical intervention. Without ductal patency – maintained in the neonatal period by prostaglandin E1 infusion and documented carefully in the clinical record – the defect is fatal.

The British Congenital Cardiac Association (BCCA) and the Society for Cardiothoracic Surgery in Great Britain and Ireland (SCTS) classify IAA by the location of the interruption relative to major arch vessels. Type B, involving interruption between the left carotid and left subclavian arteries, is the most common presentation and frequently co-occurs with ventricular septal defect (VSD) and bicuspid aortic valve. Type A (distal to the left subclavian) and Type C (proximal to the left carotid) are considerably rarer.

CCSD code L2360 repair of interrupted aortic arch covers the complete surgical correction of this defect. The procedure involves cardiopulmonary bypass, deep hypothermic circulatory arrest in many cases, and direct anastomosis of the aortic arch segments. Where concurrent defects are present, such as VSD, those repairs require separate CCSD codes billed alongside L2360. The CCSD Group’s schedule naming convention confirms L2360 as the designated code for this procedure in the UK private billing context.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Where It Sits in the Schedule

Within the CCSD schedule, L2360 falls under the cardiothoracic surgery chapter. The L-series codes cover cardiac and thoracic procedures. Paediatric cardiothoracic coding under CCSD requires careful attention to the scope of each code, because insurers apply the schedule’s definitions strictly when assessing claims. A procedure billed as L2360 that extends into staged repair territory – covering work completed across multiple operative episodes – may require a different coding approach or accompanying documentation explaining the clinical rationale for splitting the billing episodes.

Billing administrators working with Bupa CCSD codes or other major insurer schedules should verify the current CCSD code description against the insurer’s own fee schedule before submitting. Fee schedules are updated annually, and code descriptions can shift. Cross-referencing the CCSD technical guide (updated October 2025) is the safest way to confirm active code status before invoice submission.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Key Billing Data

The table below summarises the core billing attributes of CCSD code L2360 repair of interrupted aortic arch for quick clinical reference.

Fee amounts for L2360 are not published in this guide. All major UK insurers – including Bupa, AXA Health, Aviva, Vitality Health, WPA, Cigna, Healix, and Allianz Care – maintain their own fee schedules for CCSD-coded procedures. These amounts vary by insurer and are subject to annual revision. The Healix fee schedule and the Aviva procedure fee schedule are publicly accessible starting points for providers working with those insurers. Always request the current schedule from your recognised insurer representative before invoicing.

Coding Guidelines and Documentation Requirements for CCSD Code L2360

The CCSD Group’s technical guidance establishes the documentation standards that underpin every private billing claim. For a procedure as complex as CCSD code L2360 repair of interrupted aortic arch, the documentation burden is correspondingly high – and for good reason. Insurers assessing a claim for major congenital cardiac surgery will scrutinise the operative record in detail.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Documentation Checklist

Every L2360 claim should be supported by the following documentation. These are not optional additions – they are the minimum standard for a clean claim submission to any major UK private insurer.

• Pre-operative diagnosis: Confirmed IAA classification (Type A, B, or C), echocardiographic findings, and co-existing cardiac defects (VSD, PDA, bicuspid aortic valve)
• Pre-authorisation reference: The insurer-issued authorisation number for the procedure, obtained before the operative episode begins
• Operative report: Detailed account of the surgical approach, use of cardiopulmonary bypass, circulatory arrest technique, and the specific repair performed – direct anastomosis, patch augmentation, or interposition graft
• Anaesthesia record: Duration and type of anaesthesia, relevant to anaesthesia code submission alongside L2360
• ICU admission and discharge summary: Post-operative course, length of critical care stay, and any complications – required by most insurers for complex cardiac procedures
• Co-defect documentation: If VSD repair or PDA ligation was performed concurrently, the operative note must describe each procedure distinctly to support multi-code billing
• Pathology or imaging reports: Pre-operative cardiac catheterisation or CT angiography findings confirming the diagnosis

Incomplete operative reports are the single most common cause of delayed payment on complex cardiac surgery claims. Where the report does not clearly distinguish between the arch repair and any concurrent intracardiac work, insurers may query whether L2360 covers the entire procedure or whether additional codes are appropriate. Clarity in the operative narrative prevents this ambiguity from arising.

Private Medical Insurance Billing and Pre-Authorisation for CCSD Code L2360

All complex cardiac surgery under CCSD coding – and CCSD code L2360 repair of interrupted aortic arch is no exception – typically requires pre-authorisation from the patient’s insurer before the procedure takes place. This applies across all major UK private medical insurance providers, though the specific pre-authorisation process varies by insurer.

Pre-authorisation for L2360 involves submitting the patient’s diagnosis, proposed procedure, and clinical urgency to the insurer’s medical team for approval. In practice, neonatal emergencies may necessitate immediate surgical intervention before formal authorisation is granted. In those circumstances, most insurers have a retrospective authorisation pathway for emergency procedures. Documenting the clinical urgency clearly in the patient record – including the timeline from presentation to surgery – supports the retrospective request and reduces the risk of non-payment.

CCSD Code L2360: Insurer-Specific Billing Requirements

Each major UK insurer maintains its own requirements for CCSD claim submission. The following reflects publicly available guidance from recognised insurers. Practices should confirm current requirements directly with each insurer, as policies are subject to change.

Bupa: Claims for complex cardiothoracic procedures are submitted via Bupa’s recognised provider portal or through Healthcode. The Bupa code search tool allows providers to verify CCSD code acceptance and check for any Bupa-specific code modifications before submitting. Bupa requires pre-authorisation for all elective cardiac surgery and expects the authorisation reference on the invoice.

AXA Health: Surgical invoices are submitted using AXA’s specialist procedure code system. The AXA Health procedure code portal publishes current accepted codes and chapter-level fee information. AXA Health requires itemised invoicing for complex procedures with multiple co-codes.

Aviva: The Aviva invoicing guidelines specify how CCSD codes should be presented on invoices for complex surgical episodes. Aviva requires separate line items for the primary procedure and each co-coded procedure, with supporting documentation available on request.

Vitality Health: Providers can use the Vitality fee finder to look up the current fee applicable to L2360 under the Vitality schedule. Vitality applies unbundling rules, so billing administrators should verify that each co-code is accepted as a separate billable item and not subsumed within the primary code.

Cigna: The Cigna UK fee schedule outlines CCSD-based reimbursement rates and contains explicit guidance on unbundling rules for complex procedures. Providers treating internationally insured patients through Cigna should note that different plan structures may affect coverage for congenital cardiac surgery.

CCSD Code L2360: Related Codes and Co-Coding Guidance

Interrupted aortic arch rarely presents in isolation. The majority of surgical cases involve concurrent intracardiac defects, and CCSD billing for L2360 almost always involves co-coding for one or more additional procedures. Getting the co-coding right requires both an accurate operative report and an understanding of how the CCSD schedule treats concurrent work.

CCSD Code L2360 Related Codes: Frequently Co-Billed Procedures

The following procedures are commonly performed alongside the repair of interrupted aortic arch and may require separate CCSD codes. Billing administrators should confirm the current CCSD code reference for each, as code numbers are subject to update by the CCSD Group.

• Ventricular septal defect (VSD) repair: VSD co-occurs in approximately 50% of IAA cases. Where VSD repair is performed in the same operative episode as the arch repair, it is typically billed as a distinct procedure with its own CCSD code. The operative report must document each step of the intracardiac repair separately from the arch reconstruction to support multi-code billing.
• Patent ductus arteriosus (PDA) ligation: PDA management – whether surgical ligation or device closure – may be performed concurrently or as a staged prior procedure. If performed in the same operative episode as L2360, the clinical record should clarify the sequence and method.
• Cardiopulmonary bypass: Use of bypass is not automatically included within L2360 under CCSD rules. Billing administrators should confirm whether bypass is a component of the L2360 description or requires a separate procedural code in the current CCSD schedule.
• Anaesthesia codes: Cardiac surgical anaesthesia for congenital procedures carries its own CCSD coding requirements. The anaesthetic team typically invoices separately, but coordinating documentation between surgical and anaesthetic teams reduces the risk of conflicting claims at the insurer level.
• Post-operative critical care: ICU admission following complex congenital cardiac surgery may attract additional per-diem or episode codes depending on the insurer’s fee structure. Confirm coverage terms with the relevant insurer at the pre-authorisation stage.

Where uncertainty exists about whether a concurrent procedure is included within L2360 or should be co-coded separately, the CCSD Group’s technical guide provides the authoritative interpretation. Consulting the guide before submission – rather than after a query – prevents retroactive coding disputes.

CCSD Code L2360 and OPCS-4: Cross-Reference Guidance

OPCS-4 (the Classification of Interventions and Procedures used by the NHS) contains codes for aortic arch repair within the K-series. However, the direct mapping between OPCS-4 K-series codes and CCSD L2360 is not confirmed in publicly available documentation at the time of writing, and billing administrators should exercise caution when cross-referencing these two systems. For NHS-private crossover scenarios – such as procedures performed under private care in an NHS facility – clinicians may need to document both CCSD and OPCS-4 codes in the patient record. The NHS Classifications Browser is the authoritative source for current OPCS-4 procedure codes.

CCSD Code L2360: Common Denial Reasons and How to Avoid Them

Claims for CCSD code L2360 repair of interrupted aortic arch are among the more complex submissions in private cardiothoracic billing. Several patterns account for the majority of insurer queries and denials on this code.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Missing Pre-Authorisation

Submitting a claim without a valid pre-authorisation reference is the most straightforward denial to prevent. Every non-emergency L2360 procedure should have an insurer-issued authorisation number recorded in the billing file before the patient is admitted. For emergency procedures, activate the insurer’s retrospective authorisation pathway on the first working day after surgery and document the clinical emergency clearly in the patient record. The Association of British Insurers (ABI) member guidance acknowledges that emergency cardiac procedures present unique authorisation challenges – using this framework supports your retrospective claim.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Incomplete or Ambiguous Operative Reports

An operative report that bundles all surgical work into a single narrative – without distinguishing the arch repair from intracardiac procedures – gives insurers grounds to question the multi-code billing. Each procedure line on the invoice needs a corresponding passage in the operative report that describes it distinctly. Surgical teams should brief their documentation practices with the billing team periodically. Practices managing digital patient records can use structured note templates to ensure operative documentation meets billing requirements consistently.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Unbundling Disputes

Unbundling occurs when a procedure billed as multiple separate codes is deemed by the insurer to be included within a single comprehensive code. For L2360 claims that include co-codes for bypass, VSD repair, or PDA ligation, the risk of an unbundling query is real. The Healix fee schedule guidelines explicitly address unbundling for complex cardiac surgery. Review the current insurer-specific unbundling rules before invoicing, and document why each co-coded procedure is clinically distinct and billable separately.

CCSD Code L2360 Repair of Interrupted Aortic Arch: Submission via Healthcode

Healthcode is the UK’s primary electronic billing network for private healthcare, and CCSD code submissions via Healthcode are broadly supported for cardiothoracic procedures. When submitting L2360 via Healthcode, ensure the invoice includes the correct CCSD code, the pre-authorisation reference, the treating clinician’s GMC number, and the hospital facility code. Electronic submission reduces the administrative lag associated with paper invoicing and provides a documented audit trail – important for complex claims that may attract insurer review. Practices using integrated claims management software can automate parts of this workflow, reducing manual entry errors on high-value surgical claims.
