CCSD code E5703 – Bilateral open bullectomy, with or without pleurodesis

Key takeaways

CCSD code E5703 covers open bilateral thoracotomy bullectomy, not a unilateral or VATS approach.

Pleurodesis performed at the same operative sitting is captured within E5703 and must not be billed separately.

Missing pre-authorization from the insurer before the procedure is a common reason for outright claim rejection.

Pabau’s claims management software helps UK private practices track pre-auth references, attach operative documentation, and submit CCSD-coded invoices to insurers.

CCSD code E5703: What the descriptor covers

CCSD code E5703 is defined by the Clinical Coding and Schedule Development Group as “thoracotomy bullectomy – bilateral +/- pleurodesis.” Every word in that descriptor carries billing significance. Thoracotomy specifies an open surgical approach.

Bullectomy bilateral means bullae are excised from both lungs in the same operative episode. The +/- pleurodesis clause means pleurodesis, when performed, is captured within this code and does not attract a separate billing line.

That clause is newer than many billing templates. CCSD added “+/- pleurodesis” to the E5703 narrative in August 2024. A template built on the older “Thoracotomy bullectomy – bilateral” wording may still prompt a separate pleurodesis line.

Knowing the full scope prevents two expensive coding errors. The first is using E5703 for a video-assisted thoracoscopic surgery (VATS) approach. The second is adding a standalone pleurodesis code on the same claim.

The procedure: What a bilateral thoracotomy bullectomy involves

A bilateral bullectomy via open thoracotomy addresses disease in both lungs during a single anesthetic episode. The surgeon makes standard posterolateral thoracotomy incisions on each side, identifies the bullae, and excises them using stapling devices or suture techniques. The operative sequence matters for documentation purposes.

1. Patient positioning and anesthesia: Double-lumen endotracheal tube for single-lung ventilation, lateral decubitus positioning for each side.
2. Bilateral thoracotomy incisions: Open chest access on the left and right, confirmed explicitly in the operative note.
3. Bulla identification and excision: Visually confirmed bullae excised, with specimens sent to histopathology where indicated.
4. Pleurodesis (when performed): Mechanical pleurodesis via pleural abrasion, or chemical pleurodesis using talc or another sclerosant. Document the method, agent, and volume.
5. Intercostal drain placement: Chest drains inserted bilaterally before closure. A drain placed at the same sitting is expected and does not attract a separate code.
6. Closure and recovery: Standard layered closure, with drain output monitored post-operatively.

The operative note must confirm bilateral approach and bulla excision. Insurers will reject claims where the note only documents one side or uses the word “thoracoscopic.”

Clinical indications: When pneumothorax and bullous disease justify E5703

E5703 applies when bilateral lung pathology requires open surgical intervention. The two principal indications are recurrent bilateral spontaneous pneumothorax and bilateral bullous emphysema with significant hemodynamic or respiratory compromise.

• Recurrent bilateral spontaneous pneumothorax (ICD-10 J93.1): Two or more ipsilateral events, or first-presentation bilateral involvement, where conservative and drain management has failed.
• Bilateral bullous emphysema (ICD-10 J43.9): Giant bullae occupying more than one-third of hemithoracic volume bilaterally, causing exertional dyspnea, infection risk, or hemodynamic compromise.
• Giant bilateral bullae with compression (ICD-10 J43.9): Compression atelectasis of adjacent lung parenchyma, where resection is expected to restore functional capacity.

The responsible clinician assigns the ICD-10 diagnostic code. Billing teams must not select or alter diagnostic codes independently. Pre-operative CT chest imaging and pulmonary function test results support the medical necessity argument insurers require.

E5703 vs neighboring CCSD codes: Choosing the right one

CCSD code E5703 sits within the thoracic surgery chapter alongside several codes that share similar procedural language. Selecting the wrong code is a common reason for upcoding allegations and insurer audits. The critical distinctions are surgical approach (open vs thoracoscopic) and laterality (bilateral vs unilateral), and the grid below pairs each combination with its code.

If the note describes one lung only, the open-approach code is E5704. When pleurectomy or pleurodesis for pneumothorax is the main operation, E5705 is the closer match.

Descriptors in this table match the CCSD schedule as checked in October 2026. Verify them against the current CCSD Technical Guide before submitting, because narratives change between editions. For thoracic codes outside the bullectomy family, use the CCSD code index. For Bupa-specific lookups, refer to the Bupa CCSD code guide.

VATS bullectomy vs open thoracotomy: Why the approach decides the code

Using E5703 for a VATS bullectomy may constitute upcoding because VATS carries a distinct CCSD code reflecting the thoracoscopic approach. Payers treat open thoracotomy and VATS as different procedures. Open thoracotomy involves a larger incision, longer anesthetic time, greater post-operative morbidity, and a longer inpatient stay. Billing VATS as an open thoracotomy code inflates the claim above what the procedure warrants.

The operative note is the definitive record. If it states “thoracoscopic,” “VATS,” “port access,” or “minimally invasive,” E5703 does not apply. A bilateral VATS bullectomy is coded E5591, and the one-lung version is E5590.

Is pleurodesis separately billable when performed with E5703?

No. When pleurodesis is performed during the same operative sitting as the bilateral bullectomy, it is captured within CCSD code E5703. The +/- notation in the official descriptor signals this. The code covers the bullectomy with or without pleurodesis, and the reimbursement value already accounts for the additional step.

Billing a standalone pleurodesis code alongside E5703 for the same date of service constitutes unbundling. That will trigger claim rejection and may result in an audit.

One legitimate exception applies. If pleurodesis is performed as a staged, standalone procedure on a different date from the bullectomy, a separate pleurodesis code may be appropriate. Confirm with the insurer before submitting in that scenario.

Documentation requirements to support an E5703 claim

Insurers validate E5703 against the operative note. A note that omits any of the following elements gives the payer grounds to reject, query, or reduce payment. Thoracic surgical teams and billing coordinators should run a structured post-operative documentation checklist before a claim is submitted.

• Approach stated explicitly: “Open thoracotomy” or “posterolateral thoracotomy,” never “minimally invasive” or “thoracoscopic.”
• Bilaterality confirmed: Both left and right sides documented as operated in the same sitting.
• Bullae identified and excised: Location, number, and excision method (stapler type, suture technique).
• Pleurodesis method documented (if performed): Mechanical abrasion or chemical agent, volume used, and distribution.
• Chest drain placement: Size, position, and initial output bilaterally.
• Histopathology request: If bullae specimens are sent, note the request and specimen labeling.

Pre-operative documentation supporting medical necessity must also be filed with the claim. This includes a CT chest report confirming bilateral bullous disease, pulmonary function test results, the consultant referral letter, and the signed anesthetic assessment. Without these, insurers will query the clinical justification even if the code selection is correct.

Pre-authorization requirements from UK private medical insurers

All major UK private medical insurers require pre-authorization before elective thoracic surgery. Submitting an E5703 claim without a valid pre-auth reference number is the fastest route to a zero-payment outcome. Requirements and time limits vary by insurer, so check each payer’s provider guidance before any procedure.

In a UK private practice, the pre-auth check belongs in the booking workflow, before the theater date is confirmed. The table below reflects general expectations as of publication.

All pre-auth data in this table reflects general industry expectations as of early 2026. Verify current requirements with each insurer before any procedure. Requirements change, and individual policies may impose additional conditions.

Common reasons E5703 claims are rejected

E5703 rejections usually trace back to a short list of documentation or code-selection errors. Billing teams see the same patterns again and again with complex thoracic procedures.

• VATS billed as E5703: The operative note says “thoracoscopic,” but E5703 (open thoracotomy) is submitted. This may constitute upcoding. Remedy: Confirm the approach with the surgeon before code selection, and use the correct VATS code.
• Pleurodesis billed separately: A standalone pleurodesis code is added to the E5703 line. This is unbundling, because the +/- notation means pleurodesis is already captured. Remedy: Remove the separate pleurodesis line from the claim.
• Missing pre-authorization: No valid pre-auth reference number on the claim. Remedy: Obtain the reference before the procedure and record it in your billing system before generating the invoice.
• Operative note does not confirm bilateral: The note documents only one side, or uses ambiguous language. Remedy: Return to the surgeon for an addendum before submitting.
• Incorrect or missing ICD-10 code: No diagnostic code attached, or a non-specific code used. Remedy: The responsible clinician must assign the correct ICD-10 code before the claim is submitted.
• Missing anesthetic code: A bilateral open thoracotomy needs the anesthetist’s own code billed alongside it. Omitting it leaves the claim out of step with the procedure’s complexity.
• Wrong consultant registration number: The claim goes in under a consultant number that does not match the insurer’s recognized provider record. Remedy: Cross-check the consultant’s recognition number with each insurer before first submission.

Co-billing and add-on codes commonly used with E5703

Some ancillary procedures and post-operative services attract separate codes alongside E5703. Others are bundled and cannot be billed independently. Claiming a bundled service creates unbundling risk, while missing a legitimately separate service leaves revenue unclaimed.

How to submit an E5703 claim: Step by step

Private hospital billing teams and independent consultant rooms follow broadly the same sequence for CCSD code E5703 submissions. Using medical billing software that supports CCSD code submission cuts manual errors at each step.

1. Obtain pre-authorization before the procedure. Call or submit online to the insurer with the proposed CCSD code, ICD-10 diagnosis, consultant name, and proposed date. Record the reference number immediately.
2. Surgeon completes the operative note on the day of surgery. The note must confirm open thoracotomy, bilateral approach, bulla excision details, and pleurodesis status. Do not submit without a completed note.
3. Coder assigns E5703 plus the ICD-10 diagnosis code. The responsible clinician should sign off on the diagnostic code. Cross-check approach and laterality against the note one final time.
4. Attach supporting documents. Pre-auth reference, CT report, referral letter, PFT results, anesthetic assessment, and operative note. Missing even one document delays payment.
5. Submit within the insurer’s time limit. Time limits vary by insurer; check each payer’s provider guidance. Late claims are rejected on process grounds regardless of clinical validity.
6. Follow up on the remittance advice. Check the remittance for partial payments or query codes. A partial payment often signals a bundling dispute or missing document rather than outright rejection. Respond within the insurer’s appeal window, which also varies by payer.

How Pabau keeps E5703 claims complete before submission

In many UK private practices, an E5703 claim is assembled from several places. The pre-auth reference sits in an email, the operative note in a hospital system, and the CCSD code in a spreadsheet. Each handoff is a chance to drop the bilateral confirmation or add a pleurodesis line.

Pabau, the practice management and billing platform we build, keeps those pieces on the patient record. The pre-auth reference, the operative documentation and the CCSD-coded invoice sit together. Your billing team can check them against each other before the claim goes to the insurer.

The outcome is fewer claims returned for missing documents, and a clear view of which E5703 invoices are still waiting on payment.

Conclusion

Code E5703 only when the operative note proves two facts. The surgeon used an open thoracotomy, and bullae came out of both lungs in one sitting. If either fact is missing, the claim belongs under a neighboring code, and the insurer will spot it in the note.

Checking the note, the pre-auth reference and the bundled pleurodesis takes minutes before submission. Unpicking a rejected claim afterward costs your team far more time.
