CCSD Code A5110: Excision of Intradural Lesion Billing Guide

Key Takeaways

CCSD Code A5110 describes excision of an intradural lesion, classified as Complex Major complexity.

A5110 sits in Chapter 3 (Spine, spinal cord and peripheral nerves) of the CCSD Schedule of Procedures.

Freedom Health Insurance pays £1,300 (procedure) and £642 (anaesthetist) for A5110, effective 01/04/2026.

Pre-authorisation is required by most UK private insurers before billing A5110; check each insurer directly.

Pabau’s claims management software supports electronic CCSD claim submission via Healthcode integration.

A misapplied or missing CCSD code is the fastest route to a rejected claim. For neurosurgeons and spinal specialists billing UK private insurers, CCSD Code A5110 is one of the most consequential codes in Chapter 3. It covers excision of an intradural lesion, a complex spinal procedure that triggers pre-authorisation requirements, specific complexity grading, and fee schedule variations across major insurers including Bupa, AXA Health, and Freedom Health Insurance. This guide covers the clinical definition, complexity classification, verified fee data, pre-authorisation requirements, and claim submission workflow for CCSD Code A5110.

Errors here cost practices both time and revenue. Understanding the sequencing rules, insurer-specific requirements, and co-billing restrictions for this code before submitting a claim will significantly reduce rejection risk.

CCSD Code A5110: Definition and Clinical Description

CCSD Code A5110 is defined as “Excision of intradural lesion.” The term refers to the surgical removal of a lesion located within the dura mater, the outermost of the three membranes (meninges) surrounding the spinal cord and brain. Intradural lesions include meningiomas, schwannomas, ependymomas, and other tumours or cysts situated inside the dural sac.

This is a major open spinal surgical procedure requiring general anaesthesia, intraoperative neurophysiological monitoring in many cases, and a hospital stay of several days. The procedural complexity directly informs how insurers classify and reimburse the code. According to the CCSD Schedule of Procedures, procedure codes are assigned complexity grades that determine fee banding across the UK private healthcare sector.

A5110 sits in Chapter 3 of the CCSD Schedule, which covers Spine, spinal cord and peripheral nerves. Clinics working in neurosurgery or spinal surgery should note that multiple CCSD codes in this chapter carry specific co-billing restrictions. Understanding the chapter context is essential for accurate invoicing. Practices transitioning from NHS to private practice often encounter these distinctions for the first time when billing insured spinal procedures.

Fee Schedule and Reimbursement Rates

Reimbursement rates for A5110 vary materially across UK private insurers. The table below shows verified fee data from insurer schedules. Always confirm current rates directly with each insurer before submitting, as fee schedules are updated periodically.

Important: The Guernsey surgical fees list (2021) shows A5110 at £6,030, but this figure is from a 2021 document and should not be used as a current mainland UK benchmark. Always use the most recent insurer-specific schedule.

Complexity Classification and Chapter 3 Context

The CCSD Schedule assigns each procedure code a complexity grade. These grades determine the fee band applied by insurers and help indicate the level of clinical skill and resource required. For A5110, the classification varies slightly depending on the insurer’s own schedule wording:

• Complex – as listed in the Freedom Health Insurance Chapter 3 schedule (effective 01/04/2026)
• Complex Major – as listed in the National Friendly schedule of fees

The CCSD complexity grades in ascending order are: Minor, Intermediate, Major, Complex, and Complex Major. A5110 sits near the top of this hierarchy regardless of which insurer wording is used. Verify the exact grade against the official CCSD Schedule for your insurer contracts, since fee banding is applied at the insurer level and the CCSD maintains the canonical grade definitions.

Within Chapter 3, the CCSD and individual insurers apply specific coding principles. For spinal surgery, one important rule is that multiple-level surgery does not constitute a multiple procedure and is not reimbursed as such, except in the cervical region (as noted in the AXA Health Chapter 3 coding principles). This directly affects how you bill A5110 when a surgeon operates at more than one spinal level during the same encounter. Clinics managing spinal surgery invoicing should review the Bupa procedure codes fee schedule alongside insurer-specific Chapter 3 guidance to confirm whether any co-procedure restrictions apply.

Documentation Requirements for A5110 Claims

A5110 is a Complex Major procedure under Chapter 3 of the CCSD schedule, and insurers expect documentation that confirms the procedure performed matches the code billed. The following documentation elements support an A5110 claim and reduce the risk of post-submission queries or audit holds.

• Operative note: A detailed operative report confirming the spinal level operated (cervical, thoracic, lumbar), the intradural lesion identified, the surgical approach used, and whether A5110 was performed as the sole procedure or alongside any concurrent code. The note should explicitly identify the lesion type (intramedullary, extramedullary intradural, or extradural where applicable) and the resection extent achieved.
• MRI imaging: Pre-operative MRI is the standard imaging modality for intradural spinal lesion confirmation. The imaging report should be available with the claim file and should clearly identify the lesion location and characteristics that justified surgical intervention. Insurers reviewing high-complexity spinal claims regularly request the MRI report.
• Intraoperative neurophysiological monitoring (IONM) records: Where IONM was used, which is common for intradural surgery to protect spinal cord function, the monitoring report should be included in the documentation pack. If IONM is being billed as a separate component, retain the monitoring technologist’s record alongside the operative note. If IONM is bundled under the insurer’s rules, the report still serves as evidence that the monitoring was performed.
• Anaesthetic record: The anaesthetic record confirms general anaesthesia and identifies the anaesthetist who took primary charge of the case. This record supports anaesthetist fee claims, which are submitted separately from the surgical fee.
• Lesion histology where available: Where tissue was sent for histopathological analysis, the histology report should be retained and made available to the insurer if requested. Histology is not usually required at first claim submission, but it strengthens the documentation pack on audit and supports the medical necessity case if the diagnosis is challenged.
• Consultant primary-charge attestation: The consultant who performed the procedure must be identified in the record as the clinician in primary charge of the case. This is particularly relevant where multiple consultants are involved (e.g. spinal surgeon, neurologist, anaesthetist) and only the consultant in primary charge can claim the surgical fee.

Pabau’s digital forms feature lets practices build procedure-specific clinical note templates that prompt clinicians for these elements at the point of care, reducing documentation gaps before claims are submitted.

Pre-authorisation Requirements

Pre-authorisation is required before billing CCSD Code A5110 across most UK private insurers. Because A5110 is classified as a complex or complex major procedure, insurers typically require clinical evidence of necessity before agreeing to cover the cost.

Pre-authorisation requirements vary by insurer and policy type. There is no universal rule. What applies under a Bupa corporate scheme may differ from an individual Freedom Health policy. As a general framework for spinal neurosurgery procedures at Complex or Complex Major complexity:

• Obtain a valid referral letter from a registered consultant
• Submit imaging evidence (MRI is standard for intradural lesion confirmation)
• Apply for pre-authorisation before the procedure date, not retrospectively
• Record the authorisation reference number before submitting the claim
• Confirm anaesthetist fees are included in the authorisation or submit a separate request

Practices that moved into spinal surgery from NHS environments often encounter insurer pre-authorisation workflows for the first time. If your practice is leaving the NHS for private practice, building a reliable pre-authorisation tracking process before your first complex procedure will save significant administrative time. Each insurer’s pre-authorisation portal or phone line is the definitive source. Do not assume cross-insurer consistency for this code.

Submitting a Claim for A5110 via Healthcode

Most UK private insurers receive electronic claims through Healthcode, the UK private healthcare EDI (Electronic Data Interchange) platform. Submitting CCSD Code A5110 correctly through Healthcode requires attention to a specific sequence of steps.

1. Confirm the CCSD code and description: Use the exact narrative “Excision of intradural lesion” and code A5110. Do not substitute or abbreviate.
2. Include the authorisation reference number: Every claim for A5110 must carry the pre-authorisation number issued by the insurer. Claims submitted without a valid authorisation reference are routinely rejected.
3. Record the diagnosis code: Include the relevant diagnostic code alongside A5110. For intradural lesion excision, this is typically an ICD-10-CM or CCSD diagnostic code indicating the type and location of the lesion. Confirm the correct diagnostic code with your clinical coding team.
4. Separate anaesthetist billing: If the anaesthetist is invoicing separately (as is standard in private practice), their claim uses A5110 alongside the anaesthetic complexity grading. The surgeon’s claim and the anaesthetist’s claim are submitted independently through Healthcode.
5. Submit within the insurer’s claims window: Most UK private insurers require claims within 3 to 6 months of the procedure date. Missed windows result in automatic rejection.

Using claims management software that integrates with Healthcode removes the manual entry risk from this sequence. Practices that rely on paper-based or spreadsheet billing for complex spinal codes accumulate errors that compound into denied claims and delayed revenue recovery. A private practice management platform with built-in CCSD code support helps maintain audit-ready records for each submitted claim.

Co-billing Restrictions and Common Rejection Reasons

CCSD Code A5110 carries specific co-billing restrictions within Chapter 3. Billing additional codes alongside A5110 without reviewing the chapter’s coding principles is one of the most common sources of claim rejection for spinal neurosurgery invoices.

Key co-billing rules to verify before submitting A5110:

• Intraoperative monitoring: If neurophysiological monitoring was used during the procedure, check whether it can be billed as a separate code or whether it is considered bundled into A5110 under the insurer’s rules.
• Discography and chemonucleolysis: AXA Health’s Chapter 3 coding principles note that chemonucleolysis includes discography, and discography should not be charged separately. While this specific rule applies to different codes, it illustrates the bundling logic that CCSD insurers apply throughout Chapter 3.

When in doubt, contact the insurer’s provider relations team before submission. Retrospective authorisation is rarely granted for procedures at this complexity level. For practices building their private billing workflows, the private practice billing landscape rewards preparation over correction.

Common Billing Errors and How to Avoid Them for A5110

Claim denials for A5110 typically cluster around four predictable patterns. Each is preventable with checks built into the pre-submission workflow.

• Incorrect complexity grade: Submitting A5110 at the wrong complexity tier (e.g. Major instead of Complex Major) causes underpayment or rejection depending on the insurer’s system validation rules. Verify the complexity classification on the relevant insurer’s published Chapter 3 fee schedule before invoicing, not at the point of pre-authorisation alone.
• Missing or expired pre-authorisation: A5110 is a Complex or Complex Major procedure across most UK private insurers, and pre-authorisation is required before the procedure date. Submitting without an authorisation reference, or relying on an authorisation issued for a different procedure category, results in automatic rejection. Record the authorisation reference on every claim line and confirm scope (procedure code and clinician identity) at the time of issue.
• Multi-level coding errors: Operating at more than one spinal level in the same session does not automatically support multiple A5110 line items, except in the cervical region under specific insurer rules. Claiming A5110 twice for a thoracic and lumbar lesion in the same session is likely to be rejected without explicit insurer approval. Where multi-level work is performed, contact the insurer’s provider relations team before submission rather than after rejection.
• Missing or non-specific diagnosis code: A5110 submitted without a supporting ICD-10 diagnosis code, or with a vague code that does not establish medical necessity for the intradural procedure performed, is frequently returned for clarification. Pair A5110 with the most specific applicable diagnostic code (e.g. C72.x for spinal cord neoplasms, D32.x for benign neoplasm of spinal meninges) based on the operative findings and any available histology.
