CCSD code G1400 – VATS oesophageal lesion excision

Key takeaways

CCSD code G1400 is the surgeon’s code for VATS excision of a lesion of the esophagus, listed in CCSD Chapter 8, Thorax.

G1400 covers the surgeon’s operative fee only, so the anesthetist and the hospital invoice separately.

The surgical route decides the code. Endoscopic work, such as rigid esophagoscopy (G1900), is coded separately from a VATS excision.

Bupa, AXA Health, Aviva and Vitality expect pre-authorization before the operation, and a missing reference is the most avoidable denial.

An operative note that names the thoracoscopic approach, the lesion and any conversion to open surgery is what defends the code at review.

CCSD code G1400 is a thoracic surgeon’s VATS code

CCSD code G1400 is the code a thoracic surgeon uses to bill a UK private insurer for VATS excision of a lesion of the esophagus. The surgeon removes the lesion through small chest ports, guided by a thoracoscope, instead of opening the chest.

The selection risk is the route. The same lesion can be removed through a thoracoscope, treated through an endoscope, or excised through an open incision. Each route has its own CCSD code, so G1400 only fits when the operation stayed thoracoscopic. Before you raise the invoice, check what the code pays for, where it stops and what insurers look for.

What G1400 covers, and where the invoice stops

G1400 pays the operating surgeon for the thoracoscopic excision of an esophageal lesion. It was added to the CCSD schedule in January 2010, under the Video Assisted Thoracic Surgery (VATS) category of Chapter 8.

• Included: the surgeon’s operative fee for the VATS excision, per the CCSD code principles (confirm inclusions in the CCSD login).
• Billed separately: the anesthetist’s fee, which goes on its own invoice under that insurer’s anesthetist rules.
• Billed separately: hospital charges, such as operating room time, the inpatient stay and consumables, which the hospital invoices directly.
• Coded separately: follow-up outpatient consultations after discharge.

Some code pairings are flagged by CCSD as unacceptable combinations. Those rules sit behind the CCSD login, so check G1400’s own list there before you add a second procedure code to the same episode.

Inside a VATS esophageal lesion excision

Knowing the operation makes the operative note easier to check against the code. Most lesions removed this way are benign submucosal growths, such as leiomyomas or duplication cysts.

1. Access: the surgeon places small ports between the ribs and works from a video image, usually with the lung on that side deflated.
2. Location: the lesion is found on the esophageal wall, and an endoscopy during the operation often helps confirm its position.
3. Excision: the lesion is shelled out or excised, and the surgeon checks that the esophageal lining is intact.
4. Closure: the muscle layer is repaired where needed, a chest drain may be left, and the ports are closed.

If the surgeon converts to an open thoracotomy, G1400 no longer describes the operation. Code the open procedure that was performed, and record why the conversion was needed.

Neighboring esophageal codes: The route decides the code

Esophageal lesions can be treated through a thoracoscope, an endoscope or an open incision. Each route has its own code, and the diagram below maps each one to the code that fits.

The table adds the official descriptors, plus two endoscopic codes that sit nearby in the schedule but treat a different problem.

Descriptors above come from the public CCSD code pages, and our CCSD codes library covers the rest of the schedule. Fees, exclusions and combination rules sit behind the CCSD login, so confirm them there.

Other esophageal operations have their own codes too. Repair of a ruptured esophagus, for example, is billed under G0740. For another VATS code from the same specialty, see our guide to E5591.

Payer requirements: Pre-authorization comes first

Every major UK private medical insurer wants to approve a planned VATS operation before it happens. Their referral and portal rules differ, though, so check each one on its provider portal before the operation date.

Recognition matters as much as authorization. Each insurer keeps its own list of recognized consultants. A G1400 claim from a surgeon outside that list will not be paid, however good the notes are. For the wider code structure Bupa uses, see our Bupa CCSD codes guide.

How a G1400 claim moves through Healthcode

Most UK insurers accept electronic claims through Healthcode. A clean G1400 submission follows six steps.

1. Confirm recognition: check that your billing profile is recognized by the patient’s insurer. An unrecognized profile rejects before clinical review.
2. Enter patient and policy details: add the full name, date of birth, membership number and pre-authorization reference. Any mismatch triggers a front-end rejection.
3. Enter G1400: type the code exactly as the current schedule lists it. Never swap in a nearby code to match a fee.
4. Add the diagnosis: record the condition that justified surgery, using an ICD-10 code where the insurer asks for one.
5. Attach the operative note: upload it as a PDF, especially if the case converted or ran longer than planned.
6. Track the claim: note the Healthcode reference and submission date, then follow up any claim still unpaid after 30 days.

Documentation that holds up under insurer review

Insurers don’t judge the operation itself. Instead, they judge whether your notes support the code on the invoice. For G1400, the operative record should show five things.

1. The approach: state that the operation was video-assisted thoracoscopic, and give the side of entry.
2. The lesion: its location on the esophagus, its size and the suspected or confirmed type.
3. The indication: why removal was needed, such as symptoms, growth on imaging or an uncertain diagnosis.
4. The outcome: complete excision, mucosal integrity and any drain left in place.
5. The surgeon: name, GMC number and the hospital where the operation took place.

Structured digital forms help here. When these fields are captured at the point of care, nobody has to rebuild the note from memory weeks later.

Before you submit: A five-point G1400 checklist

A two-minute check before the claim leaves the practice saves weeks of chasing afterwards. Run through these points on every G1400 invoice.

• The operation was thoracoscopic from start to finish, with no conversion to open surgery.
• The pre-authorization reference on the invoice matches the one the insurer issued.
• The surgeon is recognized by this insurer, and the invoice carries their details, not the anesthetist’s.
• No second procedure code is added without checking CCSD’s combination rules first.
• The operative note and diagnosis are attached, not just referenced.

Why G1400 claims get denied, and how to fix them

Denials on G1400 follow a predictable pattern. Most trace back to one of six causes, and each has a simple fix.

If a claim comes back denied, don’t resend the same invoice. Find which cause applies, fix it, then resubmit with a short note explaining the change. Where you disagree with the decision, use the insurer’s formal appeals route.

Common G1400 coding mistakes to avoid

Beyond denials, a few habits create audit risk. Insurers watch for code patterns that drift from what peers bill for the same work.

• Coding the plan, not the operation: if the approach changed in the operating room, the code changes too.
• Coding the wrong route: an endoscopic or open removal takes its own code, even when the lesion is the same.
• Letting admin staff pick the code: code selection is a clinical decision, made from the operative note.
• Working from an old schedule: CCSD publishes updates through the year, so check the current version before you bill.

How Pabau keeps a G1400 claim on track

In many surgical practices, the pre-auth reference lives in an email, the operative note in a hospital system, and the invoice in a spreadsheet. Each handoff is a chance for the claim to break.

Pabau brings those steps into one patient record. Its claims management software sends CCSD-coded claims to Healthcode straight from that record. It also checks that required fields, such as the membership number and authorization code, are complete before the claim goes out.

As a result, the reference captured at booking is still there at invoice time. You can also track each claim’s status in the same place.

Keep every G1400 claim tied to its pre-auth

Pabau sends CCSD-coded claims to Healthcode from the patient record and checks required fields before submission. Pre-auth references and claim status stay in one place.

Conclusion

G1400 is a narrow code. It pays the thoracic surgeon for removing an esophageal lesion by VATS. Other work on the case is billed separately. Most G1400 problems start when the route on the invoice doesn’t match the route in the operative note.

So anchor every claim to the operative note. Confirm the approach, secure pre-authorization early, and keep the anesthetist’s invoice separate. Do that, and G1400 claims tend to pay the first time. Book a demo to see how Pabau keeps CCSD claims and their pre-auth references together for private surgical practices.
