CCSD code B2983: Immediate free TRAM breast reconstruction

CCSD code B2983 is the UK private billing code for a mastectomy with immediate free TRAM flap reconstruction in one operation. The descriptor is precise. The catch is that many insurers have stopped using it. Bupa’s and The Exeter’s current schedules code free TRAM reconstruction as B2985, whether it’s immediate or delayed.

For a billing team, that means a clinically perfect claim can still bounce. Below, we’ll cover what the code means, how the claim moves from pre-authorization to payment, and what to check before you submit.

Key takeaways

CCSD code B2983 covers a mastectomy with immediate breast reconstruction using a free TRAM flap, in a single operation.

Its neighbors are B2982 (immediate pedicled TRAM), B2984 (delayed pedicled TRAM) and B2985 (delayed free TRAM).

Current Bupa and The Exeter schedules fold immediate and delayed free TRAM into B2985, so check B2983 is still accepted.

A stacked DIEP flap reconstruction is a different procedure with its own codes, so never bill it as B2983.

Claims need an operative note naming the free flap, the same-session mastectomy, laterality, the indication and a pre-authorization reference.

B2983 pairs a mastectomy with a free TRAM flap in one operation

CCSD code B2983 is the code for “mastectomy and immediate reconstruction of breast using free TRAM.” That wording comes from the States of Guernsey 2026 surgical tariff, which still publishes the code with that descriptor.

CCSD stands for Clinical Coding & Schedule Development. It is the UK body that maintains procedure and diagnostic codes for private healthcare across every specialty. Its member insurers are Aviva, AXA Health, Bupa and Vitality. The group sets codes and descriptors, while each insurer sets its own fees.

Within the schedule, B2983 sits in the breast section, inside a run of reconstruction codes. That run separates the flap type (pedicled or free) from the timing (immediate or delayed). If you’re new to the schedule, our guide to CCSD codes explains how it’s organized.

Both of those choices change the code, so they’re worth unpacking before you touch the claim.

Flap type and timing are what make it B2983

Two details decide the code: how the flap gets its blood supply, and when the reconstruction happens.

A TRAM flap uses skin, fat and part of the rectus abdominis muscle from the lower abdomen to rebuild the breast. In a free TRAM, the surgeon detaches the tissue completely. Its blood vessels are then reconnected to vessels in the chest under a microscope.

A pedicled TRAM skips that microvascular step. The flap stays attached to its original blood supply and is tunneled up to the chest. That’s why it has its own code, B2982.

Timing is the second split. B2983 is the immediate version, where the reconstructive surgeon builds the new breast under the same anesthetic as the mastectomy. A reconstruction at a later operation takes a delayed code instead.

The grid below shows how the two answers combine, and which codes current payer schedules still carry.

B2983’s reference details fit in one table

With the clinical picture settled, here’s the reference data for B2983 in one place. Fees are set by each insurer, so check the payer’s own schedule at the time of the claim.

Newer payer schedules fold B2983 into B2985

Many insurers no longer list B2983 at all. The older CCSD structure used four TRAM codes, one for each mix of flap type and timing. Newer insurer schedules have folded the immediate codes into the delayed ones, which now read “including delayed reconstruction.”

In practice, an insurer that no longer recognizes B2983 will usually expect the free TRAM reconstruction under CCSD code B2985. Ask the insurer how it wants the mastectomy itself coded, because that differs between payers.

A stacked DIEP flap never belongs under B2983

Some online sources describe B2983 as a stacked DIEP reconstruction. That descriptor doesn’t match any published schedule we checked. In Bupa’s 2026 reference, stacked DIEP reconstructions sit under B2993 and B2999, and a single DIEP flap is B2986.

The difference is easy to spot on paper. A DIEP flap spares the rectus muscle, while a TRAM flap takes part of it. The operative note should make the flap type obvious, because that single detail decides the code.

A B2983 claim clears five checkpoints before it pays

Pre-authorization comes first. Most UK private insurers expect it before a mastectomy with immediate flap reconstruction. Operating without it puts the whole claim at risk. From there, the claim follows the same path each time.

1. Check the code. Look up B2983 in the insurer’s own code search, and plan for B2985 if it’s missing.
2. Request approval before surgery. Send the proposed codes, the indication and the patient’s policy number.
3. Get written confirmation. A phone agreement is not an authorization, so wait for a reference number.
4. Quote the reference on the claim. Claims without it are often rejected on administrative grounds.
5. Watch the expiry date. If surgery moves outside the approved window, ask the insurer to extend it first.

Here’s how the first checkpoint plays out. A Bupa patient is booked for a left mastectomy with an immediate free TRAM. The surgeon’s letter lists B2983, but Bupa’s code search doesn’t.

So the billing team requests approval for B2985 and asks the provider team how to code the mastectomy. The approval, the operation and the claim now carry the same code.

Each insurer keeps its own list, so bookmark these places to check.

Run this documentation checklist before you submit

Insurers review major reconstruction claims closely, and most ask for records before they pay. Tick off each item below before the claim leaves the practice.

• Operative note: names the free TRAM flap, the microvascular anastomosis and the recipient vessels, and confirms the mastectomy happened in the same operation.
• Laterality: states left or right breast, and whether the other side was treated in the same session.
• Indication: records the diagnosis or risk-reducing reason for the mastectomy, with histology and the multidisciplinary team decision where available.
• Consent: a signed consent form covering both the mastectomy and the reconstruction.
• Pre-authorization: the insurer’s written approval reference, quoted on the claim.

Practice management software like Pabau keeps these records in one patient file, so the claim is ready when the insurer asks. Digital consent and intake forms also remove the risk of an unsigned or missing page.

B2983 denials follow six predictable patterns

Even with a clean file, a few mistakes keep coming back on this code. Most of them start before the operation, which is also where they’re easiest to fix. The table pairs each pattern with the step that prevents it.

Pabau keeps the note, the approval and the claim together

A reconstruction claim passes through several hands, from the surgeon’s operative note to the billing team’s submission. A missing reference or a retired code at any step sends it back.

Pabau’s claims management software pre-fills the claim from the patient record. It also checks required fields, such as membership numbers and authorization codes, before you can send it.

For UK private insurers, Pabau’s Healthcode integration submits CCSD-coded claims straight from the patient record. If an insurer rejects one, you correct the code in one place and resubmit.

Conclusion

With B2983, the operative note usually settles the clinical side of coding. Free or pedicled, immediate or delayed, it’s all on the page. The harder question is whether this insurer still recognizes the code.

So make the insurer’s code search your first step, not your last. Confirm the code at pre-authorization, and the claim you send after surgery will match the approval you already hold.
