Key Takeaways
CCSD Code T7602 = microvascular free tissue transfer (when added to other codes) including closure of secondary defect – a Tier 2 add-on code, not a standalone procedure code.
Always bill T7602 alongside a primary procedure code; using it as a sole procedure is an error – use T7603 for standalone microvascular free tissue transfer.
Indicative fees range from £1,483 to £8,010 depending on the insurer and percentage tier; always verify current rates directly with each insurer before invoicing.
Pabau’s claims management software helps UK private practices structure CCSD code combinations, reducing add-on code errors and supporting clean claim submission to Bupa, AXA Health, and other insurers.
CCSD Code T7602: Definition and clinical description
Private practices billing reconstructive surgery frequently run into claim errors on microvascular procedures – and the most common source is misclassifying an add-on code as a standalone one. CCSD Code CCSD defines T7602 as microvascular free tissue transfer (when added to other codes) including closure of secondary defect. That parenthetical – “when added to other codes” – is the critical detail. T7602 cannot stand alone on a claim.
The Bupa CCSD codes framework, which mirrors the broader CCSD Schedule of Procedures, groups microvascular free tissue transfer under three closely related codes: T7602, T7603, and T7604. Selecting the wrong one is a straightforward way to trigger a claim denial or an audit query. This guide explains each code’s scope, when T7602 applies, and what UK private practitioners need to know before submitting.
T7602, T7603, and T7604: Understanding the microvascular code family
The three T76xx codes each describe a distinct clinical scenario. Confusing them is the most common coding error in microvascular billing within UK private healthcare.
| Code | Description | Use as sole procedure? |
|---|---|---|
| T7602 | Microvascular free tissue transfer (when added to other codes) including closure of secondary defect | No – add-on only |
| T7603 | Microvascular free tissue transfer (as sole procedure including closure of secondary defect) | Yes |
| T7604 | Vein/artery graft as part of microvascular free tissue transfer | No – supplementary component |
T7602 applies when microvascular free tissue transfer accompanies another primary reconstructive or oncological procedure. A common example: a surgeon performing a jaw resection for malignancy also performs a free flap reconstruction in the same operative episode. The resection carries its own primary code; T7602 describes the microvascular component added to it.
Use T7603 for cases where the microvascular free tissue transfer is the sole surgical procedure that session. T7604 supplements T7602 or T7603 when a vein or artery graft is needed as part of the vascular anastomosis. These are distinct clinical scenarios, not interchangeable options.
Surgeons who regularly combine complex reconstructive procedures should review the CCSD Technical Guide (updated October 2025) for the current bundling and unbundling rules that govern how T7602 interacts with primary procedure codes.
When to use CCSD Code T7602: Clinical scenarios
The defining criterion for T7602 is surgical context: microvascular free tissue transfer performed as part of, and billed alongside, another procedure in the same operative episode. Surgeons who are opening a cosmetic surgery clinic or running an established plastic surgery practice will encounter this code most frequently in oncological reconstruction, trauma repair, and complex soft tissue coverage cases.
Common clinical scenarios where T7602 is appropriate:
- Head and neck oncological reconstruction – free flap (e.g. radial forearm, anterolateral thigh, fibula) performed alongside tumour resection
- Breast reconstruction – DIEP or TRAM flap reconstruction performed alongside mastectomy or alongside implant removal
- Lower limb reconstruction – free flap coverage of a traumatic or post-oncological defect performed alongside debridement or bone fixation
- Scalp or skull base reconstruction – microvascular flap repair added to a neurosurgical or ENT procedure
In each scenario, a separate primary procedure code accounts for the resection, fixation, or debridement. T7602 codes the free tissue transfer added to it. When no primary procedure accompanies the free flap work, T7603 is the correct choice.
Practices running a plastic surgery practice management system benefit from having code templates that automatically pair T7602 with its required primary procedure, reducing the risk of submitting the add-on code alone.
Pro Tip
Before submitting any claim using T7602, confirm that the primary procedure code is present on the same claim line. Many claim denials for T7602 are not about the microvascular code itself – they are about the missing primary code that T7602 is supposed to accompany. Check the CCSD Technical Guide’s bundling rules if you are unsure which primary codes can legitimately accompany T7602.
Fee schedules and indicative pricing for T7602
CCSD Code T7602 carries some of the higher indicative fees in the microvascular code family, reflecting the technical complexity of free tissue transfer and its add-on nature within multi-procedure operative episodes. Fee figures vary significantly by insurer, year of schedule, and the percentage tier applied to the surgeon’s base rate.
Based on the ICD (UK) Ltd Surgical Fees Schedule 2023, indicative fee ranges for T7602 across percentage tiers are as follows. Treat these as illustrative only — do not use them as current billing rates without verifying directly with the relevant insurer.
These figures are from a 2023 schedule. Always confirm current rates with the specific insurer at the time of billing. Bupa, AXA Health, Healix, and other UK private insurers each maintain their own fee schedules, and T7602 rates may differ from the above. The Bupa code search portal, AXA Health specialist code portal, and Healix fee schedule each allow registered providers to look up current reimbursement rates for T7602 directly.

Coding rules and claim submission for CCSD Code T7602
Getting the clinical indication right is only half the work. The following rules govern how T7602 is correctly positioned on a UK private healthcare claim.
Add-on code sequencing
T7602 must appear on the claim alongside the primary procedure code it supplements. It cannot be submitted as the sole procedure. Most UK private insurers, including Bupa and AXA Health, will reject a claim that lists T7602 without an accompanying primary code. The primary code should reflect the principal operative work performed – the resection, reconstruction, or repair that necessitated the free flap.
Combining T7602 with T7604
Where a vein or artery graft is required as part of the microvascular anastomosis, you can add T7604 to the claim alongside T7602 and the primary code. T7604 describes the vascular graft component specifically; it is not a substitute for T7602. Check the insurer’s current coding principles bulletin to confirm whether T7604 can be claimed separately from T7602 under that insurer’s schedule, as bundling rules vary.
Pre-authorisation requirements
Most UK private insurers require pre-authorisation for major reconstructive procedures. When obtaining authorisation, ensure the reference covers both the primary procedure and the microvascular component. Do not list only the primary procedure and add T7602 at invoicing — insurers flag this regularly. Failure to include T7602 in the authorisation request is a common source of post-claim disputes. Authorisation requirements can change; always verify current rules with the insurer’s provider services team before the operative date.
OPCS-4 alignment
T7602 is a CCSD code, not an OPCS-4 code. Private healthcare billing in the UK uses CCSD codes, while NHS secondary care uses OPCS-4. The two systems are distinct and should not be conflated on claims. If your practice also handles NHS-funded episodes within a private facility, confirm which coding system applies to each claim before submission. Practices handling the transition from NHS work to private practice should review the practical differences when leaving NHS for private practice.
Streamline your CCSD billing workflow
Pabau helps UK private practices manage CCSD procedure codes, build claim templates for complex multi-code procedures, and submit clean claims to Bupa, AXA Health, and other insurers – reducing rejections and speeding up reimbursement.
Insurer-specific rules for T7602
Each UK private insurer applies its own interpretation of CCSD coding principles. T7602 claims submitted to Bupa, AXA Health, Aviva, Healix, H3 Insurance, and others may be assessed under slightly different criteria. The core add-on rule (T7602 requires a primary code) is consistent across insurers. Fee levels, pre-authorisation thresholds, and bundling decisions, however, are insurer-specific.
- Bupa – uses the CCSD Schedule as the industry standard for independent healthcare procedure coding. Bupa assesses T7602 claims against its own fee schedule; use the Bupa code search portal to confirm current reimbursement rates and any applicable coding notes before submission.
- AXA Health – publishes chapter-level coding guidance on its specialist forms portal. Chapter rules for reconstructive and plastic surgery procedures govern how add-on codes including T7602 interact with primary codes.
- H3 Insurance – bases its procedure coding on the CCSD Schedule of Procedures. H3’s fee schedule (2022 and onwards) includes T7602 fee tiers aligned with CCSD conventions.
- Healix – provides a fee schedule and unbundling guidelines for CCSD-coded procedures. Healix may apply its specific unbundling rules to T7602 if the claim includes multiple reconstructive codes.
UK practitioners exploring the benefits of private practice billing will quickly find that insurer-specific rules for surgical codes require active monitoring – fee schedules update annually and insurers publish coding principles bulletins throughout the year via the CCSD Group (contactable via [email protected]).
GDPR compliance is also relevant: practices must handle patient data processed in support of a billing claim – including procedure codes and clinical documentation – in line with GDPR requirements for UK clinics. This includes retention periods for billing records and data minimisation in claim submissions.
Pro Tip
Request a copy of each insurer’s current coding principles bulletin at the start of each calendar year. Bupa, AXA Health, and other major UK private insurers update their schedules annually. A coding rule that applied to T7602 in January may have changed by October. The CCSD Group also publishes quarterly coding principles bulletins – sign up at ccsd.org.uk to receive them.
Common errors when billing T7602
Microvascular billing errors are rarely about clinical documentation – they are usually about code selection and claim construction. These are the most common mistakes practices make with T7602.
- Using T7602 as the sole procedure – submitting T7602 without a primary code. Use T7603 when the free tissue transfer is the only procedure performed that session.
- Omitting T7604 when a vascular graft was performed – if a vein or artery graft was part of the anastomosis, T7604 should accompany T7602 and the primary code. Omitting it understates the procedure and reduces legitimate reimbursement.
- Using T7602 on NHS claims – T7602 is a CCSD code used in UK private healthcare billing. It does not apply to NHS secondary care claims, which use OPCS-4 codes.
- Failing to include T7602 in the pre-authorisation request – obtaining authorisation for the primary procedure only, then adding T7602 at invoicing, is a frequent source of disputes with insurers.
- Applying incorrect percentage tiers – T7602 fee tiers (67%, 50%, 25%) are not self-selected by the surgeon. The insurer’s fee schedule and the contract under which the practice is recognised determine them.
Practices that use claims management software for UK private healthcare can build validated claim templates for complex multi-code procedures. This reduces the likelihood of these errors reaching the insurer. A template that requires a primary code before T7602 can be selected catches the most common rejection reason at the point of claim construction. That is far better than discovering the error after a denial.

Practices working in the field of private healthcare in the UK often find that billing accuracy for complex surgical codes has a direct impact on cash flow, particularly for high-value procedures like microvascular reconstruction where the difference between a clean claim and a denial can represent several thousand pounds per operative episode.
Conclusion
T7602 covers a technically demanding procedure as a specific add-on code. Its billing rules are clear once understood: it must accompany a primary procedure code, it differs from T7603 (sole procedure) and T7604 (vascular graft component), and fee levels vary materially by insurer and percentage tier.

Frequently Asked Questions
CCSD Code T7602 covers microvascular free tissue transfer (when added to other codes) including closure of secondary defect as a UK private healthcare procedure code. It is an add-on code, meaning you must always bill it alongside a primary procedure code and cannot use it as the sole procedure on a claim.
Use T7602 when the surgeon performs microvascular free tissue transfer as part of a multi-procedure operative episode and adds it to another primary code. Use T7603 when the microvascular free tissue transfer is the sole procedure performed that session, coded independently without a primary accompanying code.
Yes, in most cases. T7604 codes a vein or artery graft performed as part of the microvascular anastomosis. When a vascular graft was required during the free tissue transfer, you can add T7604 to the claim alongside T7602 and the primary procedure code, provided each insurer’s current bundling rules permit it.
Fee schedules for T7602 vary by insurer and insurers update them annually. Use the Bupa code search portal (codes.bupa.co.uk), the AXA Health specialist code portal, or the Healix fee schedule portal to look up current rates. Use published indicative figures (such as the ICD (UK) Ltd 2023 schedule) only for orientation, not as current billing rates.
No. CCSD created T7602 exclusively for UK private healthcare billing. NHS secondary care claims use OPCS-4 procedure codes, a separate classification system entirely. Never submit T7602 on an NHS claim.
