CCSD code E5704 – Thoracotomy bullectomy billing guide

Key takeaways

CCSD code E5704 covers a unilateral open thoracotomy bullectomy, with or without pleurodesis, in a patient with emphysema.

VATS bullectomy (E5590), robotic-assisted bullectomy (E5708) and bilateral thoracotomy bullectomy (E5703) each have their own CCSD code.

Pleurodesis done in the same operation is included in E5704, so it is not billed as a second procedure.

UK private medical insurers such as Bupa, AXA Health, Aviva and Vitality usually expect pre-authorisation before admission.

Pair E5704 with an ICD-10 emphysema code from J43, and add a J93 pneumothorax code where it is part of the indication.

CCSD code E5704: definition and official descriptor

CCSD code E5704 is the UK private-insurance procedure code for a unilateral open thoracotomy bullectomy, with or without pleurodesis, in the presence of emphysema. The official descriptor reads: Thoracotomy bullectomy – unilateral +/- pleurodesis in presence of emphysema. Each part of that wording is a claim condition.

The schedule is maintained by CCSD, the Clinical Coding & Schedule Development Group, which UK private medical insurers set up to share one procedure code set. Bupa, AXA Health, Aviva and Vitality are among the insurers that use CCSD codes. Each insurer still sets its own fees and claim rules. Our CCSD billing guides cover the other codes in the schedule one at a time.

E5704 sits in Chapter 8 (Thorax and intra-thoracic organs), in the Bronchi/lungs/pleura section. Our Bupa CCSD codes guide explains how to look up one insurer’s fee for a code like this.

Four conditions in the descriptor decide whether E5704 applies. All four must be met and documented.

What happens during a thoracotomy bullectomy

In a thoracotomy bullectomy, the surgeon opens the chest through a posterolateral incision and finds the emphysematous bullae on the affected lung. The bullae are excised, typically by stapled resection. The surgeon then checks the remaining lung, controls bleeding and places intercostal drains before closing.

If the plan includes pleurodesis, the surgeon abrades the parietal pleura or instils a sclerosing agent such as talc before closure. Coders should confirm the following points from the operative report before assigning E5704.

1. Approach confirmed as open thoracotomy. The notes describe a chest incision, not port sites, thoracoscopic entry or a surgical robot.
2. Bullae identified and excised. The operative or pathology description names bullae or emphysematous blebs as the resected tissue.
3. Side documented. The report states left or right lung, because E5704 covers one side only.
4. Emphysema confirmed. Pre-operative imaging, lung function results or the consultant’s diagnosis supports a J43 code.
5. Pleurodesis status recorded. The report says whether it was performed and, if so, which method was used.

If any of these points is missing from the operative report, expect the insurer to query or reject the claim.

Clinical indications: when E5704 applies

E5704 applies when a patient with documented emphysema has bullae causing compressive symptoms or recurrent pneumothorax that conservative care cannot manage. The indication should appear in both the referral letter and the pre-operative workup. Typical indications include the following.

• Giant bullae occupying a large part of the hemithorax and compressing functioning lung tissue
• Recurrent spontaneous pneumothorax caused by bullous rupture
• Progressive breathlessness despite medical treatment, with bullous disease on CT and an obstructive pattern on spirometry
• A bulla that keeps enlarging on sequential imaging
• An infected bulla that does not respond to antibiotics

Recurrent pneumothorax needs a closer look. If the surgeon performs a pleurectomy or pleurodesis to treat the pneumothorax, rather than a bullectomy for emphysema, the claim belongs under E5705.

Insurers check that the stated indication appears in the specialist referral and the operative plan. A note that only says bullous emphysema, with no functional or structural consequence, is unlikely to pass a medical review. Each insurer runs its own review, so vague wording raises the chance of a query.

Does E5704 include pleurodesis, or is it billed separately?

Pleurodesis is included in E5704 when it is done in the same operation. The +/- in the descriptor means the code covers the bullectomy whether or not pleurodesis is performed. It is not billed as a separate item at the same sitting.

Three scenarios come up in practice, and each one is billed differently.

Do not add a pleurodesis code such as T1030 (VATS pleurodesis/pleurectomy) to E5704 for the same operation. The same applies to T1240 (insertion of tube drain into pleural cavity). Drains placed at the end of a thoracotomy are part of the operation. Verify any combination with the insurer before billing.

The CCSD Technical Guide sets out the general rules on which components fall within a main procedure code. Insurers decide individually how strictly they apply each combination rule.

E5704 vs related CCSD thoracic codes: choosing the right one

Choosing the wrong thoracic code is the most costly mistake for this procedure. The approach, the number of sides and the indication each point to a different code. The grid below shows how the first two questions settle it.

The VATS distinction carries the highest risk. Surgeons increasingly prefer thoracoscopic and robotic approaches, and a coder who defaults to E5704 will miscode those cases. Look for the words thoracotomy, posterolateral incision or open approach in the operative report. Port-site or trocar references point to VATS or robotic surgery, and a keyhole operation on both lungs is coded E5591.

Documentation requirements for E5704 claims

Thoracic surgery claims attract closer review from UK private medical insurers than most elective procedures. For E5704, assemble the full claim package before submission, because a missing document usually brings the claim back with a query.

Structured operative templates and digital intake forms capture the required details at the point of care. They also cut the back-and-forth between billing staff and the surgical team when an insurer asks for more information.

An E5704 claim is usually supported by the following documents.

• Operative report. It states the open thoracotomy approach, the bullae excised, the side and the pleurodesis status.
• Recent CT chest report. It confirms bullous disease and describes the size and location of the bullae.
• Lung function results. Spirometry should show an obstructive pattern consistent with emphysema.
• Specialist referral letter. It names the indication and, ideally, the conservative treatment that failed.
• Discharge summary. It records the primary diagnosis, the procedure, the side and the post-operative course.
• Pre-authorisation number. Insurers that require pre-authorisation match this number against the claim.
• ICD-10 diagnosis codes. Use a J43 emphysema code as the primary diagnosis, plus J93 for pneumothorax where relevant.

Pre-authorisation: what UK insurers require before approving E5704

UK private medical insurers usually expect pre-authorisation before a planned admission for surgery such as E5704. Without an authorisation number, the claim may be rejected or held for review whatever its clinical merit.

A pre-authorisation request from the treating thoracic surgeon typically includes the following.

1. Specialist referral from the GP or respiratory physician, confirming the diagnosis and the surgical recommendation
2. Recent imaging, usually a CT chest report describing the bullae
3. Lung function results showing the obstructive pattern
4. A letter of medical necessity explaining why surgery is preferred over continued conservative care
5. Admission details, including the hospital, the admission date and the expected length of stay

Requirements differ by insurer. The Bupa procedure code portal and Vitality’s fee finder both let providers look up a CCSD code before submission. Confirm the evidence list with each insurer, as their rules change.

Codes commonly billed alongside E5704

E5704 covers the surgeon’s fee for the main procedure only. Other parts of the episode are billed separately, and each one should be checked against the insurer’s rules before submission.

The Healix fee schedule shows how one administrator handles codes billed alongside a main surgical procedure. Each insurer publishes its own rules, so never assume one set applies everywhere.

Why E5704 claims get denied, and how to prevent it

Most E5704 denials come from approach miscoding, missing documents or a missing pre-authorisation. Disputes over whether the policy covers the operation are less common. The table below pairs the most frequent denial reasons with their fixes.

How Pabau supports E5704 billing through Healthcode

Many thoracic practices still track E5704 claims across operative letters, spreadsheets and insurer portals. Each handoff is a chance to drop the authorisation number or mistype the diagnosis.

In Pabau, the code, the diagnosis and the authorisation number sit on one claim record. You record the code and diagnosis on the claim, then submit it through Healthcode and track its status. Pabau does not choose the code, so the coding checks above still apply. Our claims management software page shows the full workflow.

A typical E5704 workflow runs in seven steps.

1. Create the procedure episode on the patient record, with the admission date and treating surgeon.
2. Enter CCSD code E5704 and check the descriptor matches the operation performed.
3. Add the ICD-10 diagnosis, with a J43 code first and any J93 code where documented.
4. Record the pre-authorisation number from the insurer.
5. Note the pleurodesis status in the operative record to support any audit.
6. Keep the supporting documents on the patient record, including the operative report, CT report and discharge summary.
7. Submit through Healthcode and confirm the insurer has received the claim.

Manage CCSD billing from a single platform

Pabau lets thoracic surgery practices record CCSD codes, diagnosis codes and pre-authorisation numbers on each claim. Claims then go to UK insurers through Healthcode.

Conclusion

E5704 pays for one specific operation: an open bullectomy on one lung in a patient with emphysema. Most rejected claims trace back to a coding choice made before submission, such as a VATS or bilateral case coded as E5704. A pleurodesis billed twice or a missing authorisation number causes the rest.

Settle the approach, the side and the diagnosis from the operative report first, then build the claim around them. To see how Pabau keeps CCSD claims moving from the operating list to Healthcode, book a demo with our team.
