CCSD code G1900 – Rigid oesophagoscopy billing code

Key takeaways

CCSD code G1900 covers rigid oesophagoscopy, including any biopsy, laser or diathermy destruction of lesions done during it.

Biopsy and lesion destruction are part of the G1900 descriptor, so they never go on the invoice as extra procedure lines.

A flexible scope points to the OGD codes instead, such as G6500 for a diagnostic OGD.

Bupa updated its unbundling rule for G0101, radical oesophagectomy, from 1 April 2026, and G1900 is on that list.

Pabau sends CCSD-coded claims through Healthcode and holds each one until required fields, such as the authorization code, are complete.

G1900 is the code for a rigid scope, not a flexible one

CCSD code G1900 is the UK private billing code for rigid oesophagoscopy, including biopsy, laser or diathermy destruction of lesions. It sits in Chapter 10 of the CCSD schedule, the chapter for endoscopic procedures of the gastrointestinal tract.

The word that decides the code is rigid. Surgeons reach for a rigid oesophagoscope for specific jobs, usually under general anesthetic. Most diagnostic upper GI work, by contrast, uses a flexible endoscope.

So coding starts with the instrument. If the operative note describes a flexible OGD, G1900 is the wrong code, however similar the findings look. Once the note confirms a rigid scope, a single G1900 line covers the procedure and the treatment done through it.

Biopsy and lesion destruction are already paid for

The G1900 descriptor names three steps inside the code. Biopsy, laser destruction of lesions and diathermy destruction of lesions all belong to the same rigid oesophagoscopy line.

That shapes the invoice. A surgeon who biopsies a lesion and then treats it with diathermy still bills one G1900, not three procedures.

Some work around the procedure still sits outside the code. Each of these is billed by the provider who did it:

• Anesthesia: The anesthetist bills their own fee for the session.
• Histology: The pathology provider bills for analyzing any biopsy samples.
• A second procedure: A separate operation in the same session has its own code, subject to the insurer’s bundling rules.

Put together, the scope and the descriptor decide what one G1900 line can carry.

The scope you used decides the code

G1900 shares the oesophagus with several flexible endoscopy codes and one thoracoscopic code, G1400. Match the code to the instrument first, then to the main therapeutic step in the note.

The descriptors above are quoted from Bupa’s April 2026 schedule bulletin. Confirm each one against the live CCSD schedule before you bill.

Whether two of these codes can share a claim depends on the CCSD list of unacceptable combinations. That list sits behind a CCSD login, so check it in the schedule itself rather than in a summary.

A strong operative note answers four questions

An insurer’s reviewer needs to match the note to the G1900 descriptor quickly. A note that answers these four questions makes that match easy:

• Which scope? State that a rigid oesophagoscope was used. That one word separates G1900 from the OGD codes.
• Why? Record the clinical indication that led to the procedure.
• What was found? Describe the findings and where they sit, for example as a distance from the incisors.
• What was done? List any biopsies and any laser or diathermy treatment, plus complications and how the team managed them.

Link each biopsy sample to its pathology request as well. The histology bill and the procedure bill then describe the same episode, which keeps queries short.

Bupa changed an oesophagectomy rule in April 2026

Bundling rules decide which codes an insurer will pay together. Bupa’s bulletin of 15 April 2026 lists an updated unbundling rule for G0101. That code covers radical oesophagectomy or oesophagogastrectomy, including dissection of mediastinal lymph nodes.

G1900 appears in that rule, effective 1 April 2026. Other oesophageal endoscopy codes sit on the same list, including G6500, G4410, G4430 and G4440.

In practice, a rigid oesophagoscopy in the same session as a radical oesophagectomy needs a rule check before both lines go to Bupa. The bulletin names its online code search at codes.bupa.co.uk as the current version of the schedule. Our Bupa CCSD codes guide explains how that schedule works.

Other insurers apply their own rules on top of the CCSD schedule. Check each payer’s published schedule before you treat a pairing as payable.

Three mistakes that stall a G1900 claim

Each of these slips turns a G1900 claim into a query, and each is easy to catch before the claim leaves the practice:

• Coding the findings, not the scope: A flexible OGD billed as G1900 fails the descriptor, however similar the findings look.
• Itemizing included work: Separate lines for a biopsy or diathermy treatment duplicate work the G1900 fee already covers.
• A note that never says rigid: Without that word, the reviewer cannot match the note to G1900, so the claim turns into a query.

Five checks keep a G1900 claim clean

Many UK private practices send insurer claims through Healthcode, the electronic billing exchange for private healthcare. Whichever route you use, run the same checks on every G1900 claim:

1. Confirm the authorization. Check that the patient’s insurer has authorized the procedure, and record the reference on the episode.
2. Match the code to the scope. Confirm the operative note says rigid before you select G1900.
3. Keep included work off the invoice. Leave out separate lines for biopsy, laser or diathermy done during the procedure.
4. Check bundling for a second procedure. Look up the insurer’s rules when another code shares the date, such as G0101 for Bupa.
5. Match the date and the consultant. The date of service and the treating consultant should agree with the hospital record.

Fees come from each insurer’s own schedule, not from CCSD. Check the payer’s current fee for G1900 before invoicing, so a shortfall never surprises the patient.

Pabau keeps the scope note and the claim together

Endoscopy billing often breaks between two systems. The operative note lives in one place, and someone retypes the details into a claim somewhere else.

Pabau, the practice management platform we build for private practices, holds both on the same patient record. Custom note templates let surgeons record scope type, findings, biopsies and treatment in the same order every time.

When the claim is ready, Pabau’s claims management software sends it to Healthcode from that record. It holds the claim until required fields, such as the membership number and authorization code, are complete. Claim status then shows on the record, so your team can see which claims still need attention.

Send cleaner CCSD claims from the patient record

Pabau keeps endoscopy notes, insurer details and Healthcode claims on one patient record. Your team sends G1900 claims with the authorization reference already in place.

Conclusion

G1900 is a narrow code, and that makes it easy to get right. The scope type, the descriptor and the insurer’s bundling rules settle most coding questions before anyone builds a claim.

The price is discipline in the note. When the surgeon writes rigid and lists any biopsy or diathermy, your coders can bill with confidence. When the note is vague, each claim turns into a query.

Book a demo to see how Pabau links your endoscopy notes to Healthcode claims, so every G1900 claim leaves complete.
