CCSD code B2913 – Latissimus dorsi breast reconstruction with implant

Key takeaways

CCSD code B2913 covers LD flap plus prosthesis breast reconstruction, including delayed reconstruction. Immediate reconstruction performed with a mastectomy is billed under B2912.

Both components, the flap and the prosthesis, must be confirmed in the operative note for the claim to be accepted.

Get pre-authorization from the insurer before the procedure. Claims without a valid pre-auth number are routinely rejected.

Pabau, the practice management platform we build, pre-fills CCSD claims from the patient record and sends them to Healthcode for UK private practices.

CCSD code B2913: Official descriptor and scope

CCSD code B2913 is listed in the Classification of Surgical and Diagnostic Codes schedule. Its official descriptor reads: Reconstruction of breast using latissimus dorsi including implantation of prosthesis (including delayed reconstruction). The descriptor matters in three ways.

First, it bundles two surgical components into a single code. The surgeon harvests and transposes the latissimus dorsi muscle flap, then places a breast prosthesis at the reconstruction site.

Second, the parenthetical “including delayed reconstruction” confirms the code covers reconstruction in its own operative episode, weeks, months or years after the mastectomy. A mastectomy with immediate latissimus dorsi reconstruction in the same episode has its own code, B2912.

Third, the code sits in the CCSD schedule that major UK private medical insurers use for claim adjudication. Our Bupa CCSD codes guide shows how one of those insurers applies the schedule.

The table below summarizes the code’s key attributes as they appear in the CCSD schedule.

Codes in the CCSD schedule are updated periodically, so check you are working from the current release before submitting a claim. The searchable CCSD codes library lists the neighboring breast codes in the same reference layout.

The latissimus dorsi flap procedure: Clinical overview

The latissimus dorsi flap is a myocutaneous flap taken from the patient’s upper back. The surgeon harvests a paddle of skin and the underlying latissimus dorsi muscle, keeping the neurovascular pedicle intact. The flap is then tunneled under the skin to the front of the chest wall. A breast prosthesis is then placed beneath the transposed muscle to create volume. For B2913, the operative note must document all three stages: Flap harvest, flap tunneling and prosthesis placement.

The procedure is performed under general anesthesia and is typically managed as an inpatient stay. The CCSD descriptor does not set a length of stay, so confirm the insurer’s expectations at pre-authorization. A recognized post-operative complication is seroma formation at the donor site on the back, which may require aspiration during follow-up. British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) guidance documents this complication. Any post-operative aspiration or wound management is billed separately.

Immediate vs delayed reconstruction: How timing affects billing

Timing decides the code. When the latissimus dorsi reconstruction happens in the same operative episode as the mastectomy, the combined procedure is billed under B2912. Its descriptor reads “Mastectomy and immediate reconstruction of breast using latissimus dorsi”. B2913 covers LD flap and prosthesis reconstruction without a same-episode mastectomy, which includes delayed reconstruction.

In staged reconstruction, a tissue expander is sometimes inserted at mastectomy and exchanged for a permanent prosthesis later. If the LD flap is then added at the definitive reconstruction stage, B2913 applies. The earlier expander episode is coded separately. When the expander went in at the mastectomy, that episode is usually billed as B3012.

What B2913 includes and what it does not

Understanding the scope of B2913 prevents both under-billing and unbundling errors. The table below sets out what the code bundles and what must be billed separately or verified per insurer.

The prosthesis device cost is a common source of confusion. The descriptor confirms that prosthesis implantation is within B2913 scope. Whether the insurer reimburses the device cost under the same line or as a separate supply item varies by insurer. Check the applicable insurer’s provider guide before submitting.

Adjacent codes to CCSD code B2913

Choosing B2913 correctly requires ruling out closely related CCSD codes. The table below compares B2913 with the most commonly confused adjacent codes. Specific adjacent code numbers should be verified against the current CCSD schedule release, as code numbers are periodically updated.

Three questions settle the code when you review an operative note. Was the latissimus dorsi muscle harvested and used for the reconstruction? Was a prosthesis implanted? Was the mastectomy done in an earlier, separate episode? Three yeses point to B2913, and the grid below maps the other answers.

A prosthesis placed without any flap falls outside the LD family. It is coded as B3015 for a fixed implant or B3014 for an expandable one.

Documentation requirements for a valid B2913 claim

A complete and valid B2913 claim requires specific documentation before submission via Healthcode or directly to the insurer. Missing any of these items is the most common cause of avoidable rejections.

• Pre-authorization number: A valid pre-auth reference from the insurer, obtained before the procedure. The pre-auth must specifically cover the reconstruction episode, not just the mastectomy.
• Operative note: A signed consultant’s operative report confirming all three procedural components: LD flap harvest, flap tunneling to the chest wall and prosthesis implantation. Notes that describe only one component are the leading cause of B2913 denials.
• Confirmed diagnosis: Documentation of the underlying diagnosis (typically post-mastectomy breast reconstruction), with the prior mastectomy confirmed for delayed reconstruction cases.
• Admission record: Confirmation of the episode, including admission and discharge dates. B2913 is typically performed as an inpatient procedure, so a day-case record may prompt a query from the insurer.
• Consultant registration details: The billing consultant’s GMC number and recognized provider reference for the relevant insurer.
• Correctly completed claim form: All fields populated via Healthcode, including the CCSD code, insurer membership number, date of procedure, and pre-auth reference.

Practices using digital clinical forms can structure operative documentation to capture every required component at the point of care. That cuts the time spent chasing incomplete notes before claim submission.

Pre-authorization: What Bupa, AXA Health and other insurers require

Pre-authorization is a standard requirement for breast reconstruction across the major UK private medical insurers. Billing B2913 without a valid pre-authorization number will, in most cases, result in claim rejection. The process varies by insurer, so confirm requirements through each insurer’s provider portal before proceeding.

General guidance for the main UK private insurers:

• Bupa: Reconstruction following mastectomy is typically covered when clinically indicated. The treating consultant must obtain a Bupa authorization number before the procedure. Bupa’s code search portal allows providers to verify code recognition and any linked requirements. Submitting without a Bupa authorization number means the claim will be rejected regardless of clinical merit.
• AXA Health: Requires prior authorization for all inpatient surgical procedures. The consultant’s secretary should contact AXA Health’s provider services team before booking the procedure.
• Aviva: Uses a pre-treatment authorization system. Aviva’s fee schedule covers CCSD-coded surgical procedures and can be used to verify the procedure’s recognition before submission.
• Vitality Health and other insurers: Each has its own pre-auth process. The billing team should maintain an up-to-date contact list for each insurer’s provider authorization service.

Reconstruction following breast cancer treatment is generally considered clinically indicated by UK private insurers. Policy wording and exclusions, such as cosmetic enhancement beyond the reconstructed side, still need to be confirmed per policy. Insurers may also require the clinical justification letter from the consultant, particularly for delayed reconstruction performed some years after the mastectomy.

Common reasons CCSD code B2913 claims are denied

The reasons below cover the frequent B2913 rejections in standard UK private billing practice. Each one can be caught before the claim is sent.

• Missing or expired pre-authorization: The most common reason. Claims submitted without a valid pre-auth number are rejected at triage before any clinical review. Pre-auth numbers also expire, so a procedure performed after the authorization window needs a new pre-auth.
• Operative note confirms only one component: The note records the LD flap but not the prosthesis implantation, or the reverse. The insurer then cannot verify both elements. This is B2913’s most procedure-specific denial trigger.
• Wrong code for an immediate reconstruction: Billing B2913 plus a mastectomy code for a same-episode procedure invites a rejection. The combined episode belongs under B2912.
• Incorrect bilateral coding: If bilateral reconstruction was performed, some insurers require two separate claim lines or a specific bilateral indicator. Submitting a single B2913 line for a bilateral procedure without insurer-specific guidance may result in partial payment or rejection. Confirm per insurer before submitting.
• Mismatched procedure and diagnosis codes: The diagnosis documented must support post-mastectomy breast reconstruction. If the diagnosis code on the claim does not align with a history of mastectomy, insurers will query the medical necessity.
• Late submission: UK private insurers typically impose claim submission time limits (often six to twelve months from the date of service). Claims outside this window are rejected without assessment. Check each insurer’s time limit and submit promptly.
• Unrecognized consultant: If the billing consultant is not registered on the insurer’s recognized provider list, the claim will not be processed. Ensure consultant registration is current before the procedure.

Error-checking claims management software surfaces incomplete claim fields before submission. That catches the missing operative-note details and pre-auth references behind many of these denials.

How to submit a B2913 claim via Healthcode

Healthcode is the primary electronic billing clearinghouse for UK private healthcare and the route through which most CCSD-coded claims reach insurers. For B2913, the submission process follows these steps.

1. Log in and select the correct insurer and schedule: In the Healthcode billing platform, select the patient’s insurer. Then confirm the CCSD schedule is active for that insurer. The claim form will load the relevant fields.
2. Enter CCSD code B2913: In the procedure code field, enter B2913. The descriptor will populate automatically. Check it matches the procedure, and switch to B2912 if the mastectomy was in the same episode.
3. Enter the pre-authorization reference: Paste the insurer-issued pre-auth number into the authorization reference field. This field is mandatory, and the claim cannot be submitted without it.
4. Add associated codes: Add the anesthetist’s CCSD code if billing on the consultant’s behalf (confirm this arrangement in advance). If a contralateral symmetrization or nipple reconstruction was performed in the same episode, add the relevant codes as separate lines.
5. Attach or reference supporting documentation: Where the insurer’s portal allows document attachment, attach the operative note. Where it does not, retain the note on file and be ready to supply it promptly if the insurer requests it post-submission.
6. Review and submit: Review all fields for completeness before submission. Pay particular attention to the patient membership number, the date of procedure, and the consultant’s provider reference. Submit and retain the Healthcode transaction reference for follow-up.

Billing B2913 with associated codes: Anesthesia and additional procedures

B2913 covers the surgeon’s procedural fee only. The full billing picture for an LD flap reconstruction episode typically includes several associated codes. The table below sets out the most common additional billing elements and how they relate to B2913.

In a staged pathway, the B2913 claim should reference the earlier tissue expander episode where relevant. Some insurers will request the operative note from the expander insertion episode to confirm the staged pathway.

How Pabau keeps B2913 claims complete before submission

A typical billing team tracks pre-auth numbers in a spreadsheet and chases operative notes by email. The claim is keyed into Healthcode by hand, and a missing prosthesis line only surfaces when the insurer rejects it.

In Pabau, the operative note, the insurer details and the invoice sit in the same patient record. When the invoice is ready, Pabau pre-fills the claim and sends it to Healthcode, then tracks it from Pending to Paid.

For plastic and reconstructive surgery teams, that means fewer rejected claims to rework. It also leaves a clear record linking staged episodes, from the expander insertion to the definitive LD reconstruction.

Send complete CCSD claims the first time

Pabau keeps operative notes, insurer details and CCSD claims in one patient record, then sends the claim to Healthcode without re-keying.

Conclusion

Code the episode, not just the procedure. If the mastectomy happened in the same operation, the claim belongs under B2912. If the LD flap and prosthesis come in a later, separate episode, B2913 is the right call.

Once the code is settled, two checks decide whether the claim pays. The operative note has to name both the flap and the prosthesis, and the pre-authorization has to be valid on the day of surgery.

Get those right and a B2913 claim clears triage without a query. Book a demo to see how Pabau sends reconstruction claims to Healthcode straight from the patient record.
