CCSD code M2511 – Bilateral ureterocele excision
M2511 is the CCSD code for excision of ureteroceles on both sides at the same operation, with or without ureteric reimplantation. It covers open or laparoscopic removal from the bladder wall, and any reimplantation at the same sitting is bundled into the code.
Excision on one side only is coded M2510, and endoscopic incision or puncture is coded M3202. M2511 sits in Chapter 12 of the CCSD schedule, Urinary system and male reproductive organs. Most UK private insurers require pre-authorisation before the operation.

Key takeaways
CCSD Code M2511 covers excision of a ureterocele on both sides at the same sitting, with or without ureteric reimplantation.
M2510 is the unilateral code, so a one-sided excision billed as M2511 is up-coding, and M2510 is never billed twice for a bilateral case.
Endoscopic incision or puncture of a ureterocele is coded M3202, not M2511, whichever side or sides are treated.
On a UK claim, pair M2511 with WHO ICD-10 code Q62.3, because the five-character US codes Q62.31 to Q62.39 are not valid here.
CCSD sets the code, not the fee: Bupa, AXA Health, Aviva and other insurers each set their own fee for M2511 and require pre-authorisation.
CCSD Code M2511: Definition and clinical scope
CCSD Code M2511 is the Clinical Coding and Schedule Development (CCSD) procedure code for excision of ureterocele (with or without ureteric reimplantation), bilateral. You will find it in the CCSD Schedules, which hold the standard procedure and diagnostic test codes for UK private healthcare. UK private medical insurers such as Bupa, AXA Health and Aviva use the schedule to identify procedures on claims and pre-authorisation requests.
M2511 sits in Chapter 12 of the schedule, Urinary system and male reproductive organs, under the ureter procedures. Also, you can compare it with the other Chapter 12 urology procedures in our CCSD code library.
Three parts of the descriptor decide what the code covers:
- Excision of ureterocele: Open or laparoscopic surgical removal of the ureterocele from the bladder wall. Endoscopic incision or puncture is a different procedure, coded M3202.
- With or without ureteric reimplantation: Reimplantation is optional. When the surgeon reimplants the ureters at the same sitting, M2511 already includes that step.
- Bilateral: The surgeon excises both ureteroceles, one on each side, at the same operation. If the surgeon treats only one side, the correct code is M2510.
The procedure: What bilateral ureterocele excision involves
A ureterocele is a cystic dilatation of the distal ureter where it passes through the bladder wall. It is a congenital anomaly, usually found in infancy or early childhood. It also often occurs with a duplex collecting system, where two ureters drain one kidney and the upper-pole ureter forms the ureterocele.
Surgeons choose bilateral excision when ureteroceles on both sides need surgical correction in the same operative episode. Surgeons can perform the excision by two routes, and both fall within M2511:
- Open excision: The surgeon opens the bladder, excises each ureterocele under direct vision, and reconstructs the bladder wall and bladder neck.
- Laparoscopic excision: A minimally invasive route, used where the anatomy allows and the surgeon has suitable paediatric laparoscopic training.
- With reimplantation: Surgeons add ureteroneocystostomy when excision alone would leave reflux or an inadequate ureteric orifice.
- Without reimplantation: Simple excision, used when ureteric drainage is preserved and vesicoureteric reflux (VUR) is absent.
Endoscopic decompression is often the first step in neonates and infants. It is not excision, though, so M3202 applies rather than M2511. When an open or laparoscopic excision follows later, that later operation is the one that carries M2511.
Clinical indications for bilateral ureterocele excision
The pre-authorisation request and the operative note should name one or more of these established indications:
- Bilateral ureteric obstruction: Ureteroceles causing significant hydronephrosis or impaired drainage on both sides, confirmed on ultrasound or a MAG3 renogram.
- Recurrent urinary tract infections: Obstructive or reflux-related infections that have failed conservative management. Infants are the main concern, because repeated infection risks renal scarring.
- Bilateral vesicoureteric reflux: High-grade VUR with bilateral ureteroceles, where reflux threatens renal function on both sides.
- Bilateral duplex systems with symptomatic ureteroceles: The upper-pole ureterocele causes obstruction or reflux on each side.
- Failed endoscopic treatment: Persistent obstruction or new reflux after earlier endoscopic incision on one or both sides.
Vague wording such as “bilateral renal anomaly” without a functional consequence gives the insurer no reason to approve surgery. Instead, name the indication and the imaging that confirmed it.
M2511 vs M2510: Choosing the correct CCSD code
The most important code-selection decision for this procedure is laterality. M2511 is bilateral, and M2510 covers the same excision on one side only.
CCSD builds bilaterality into the code itself. There is no bilateral modifier to add, so M2511 goes on the claim as a single line. Billing M2510 twice for a bilateral operation is incorrect, and so is listing M2510 and M2511 together for one sitting.
This differs from US CPT coding, where a unilateral code is often reported with a bilateral modifier. Under CCSD, the code alone tells the insurer that the surgeon treated both sides.
What M2511 includes and excludes
Thus, knowing the code boundaries prevents both up-coding and under-coding. The table below maps common scenarios inside and outside M2511.
Adjacent and related CCSD codes
Billers often confuse several codes near M2511 in Chapter 12 with it during claim preparation. Most errors come from misreading the approach, the laterality, or whether a ureterocele was excised at all. The Bupa CCSD code schedule explains how one major insurer applies the codes.
Key distinction: M3202 and M2511 are the pair most often confused. The operative note must state whether the ureteroceles were excised or only incised endoscopically.
Where reimplantation is the whole operation and no ureterocele is excised, use the replantation codes instead. That means M2030 for both ureters and M2080 for one.
Two questions settle the code for any ureterocele operation. First, what does the note say was done to the ureterocele? Second, how many sides were treated?

Pro Tip
When a duplex system needs heminephrectomy and ureterocele excision at the same sitting, code each procedure separately. Use M0380 for a laparoscopic heminephrectomy or M0300 for an open partial nephrectomy, alongside M2511. Document each procedure distinctly and confirm the insurer has authorised every code before surgery.
Paired ICD-10 diagnosis codes for M2511 claims
Every M2511 claim needs at least one ICD-10 diagnosis code for the condition treated. UK claims use the WHO-based ICD-10 5th Edition, which the NHS Classifications Browser publishes. Verify each code against the edition in use on the date of surgery.
UK ICD-10 stops at four characters for these codes, so Q62.3 is the code to use. Q62.31, Q62.32 and Q62.39 belong to the US ICD-10-CM and are not valid on a UK claim. In that US system, Q62.39 means other obstructive defects, not an unspecified code.
The supplementary codes are not needed on every claim. Instead, they strengthen the clinical case at pre-authorisation, and when reflux shaped the operative plan.
Documentation requirements for M2511
Incomplete operative documentation is the most preventable reason an M2511 claim comes back. The operative note must support every element of the descriptor, and it should be complete before the patient is discharged.
- Bilaterality confirmed: The note must state that the left and the right ureteroceles were both excised. A phrase such as bilateral ureterocele managed is not enough, so document each side.
- Approach per side: State whether each excision was open or laparoscopic. The approach does not change the code, but it supports clinical review.
- Excision, not incision: Describe each ureterocele being excised from the bladder wall. A note describing only incision, puncture or decompression supports M3202, not M2511.
- Reimplantation status: Record whether each ureter was reimplanted and the technique used, such as Cohen cross-trigonal or Politano-Leadbetter. If neither was reimplanted, say so.
- Anatomical findings: Note duplex systems, ectopic ureters or reflux found during surgery. These findings support the supplementary ICD-10 codes.
- Surgeon attestation: The operating surgeon signs and dates the note. An unsigned note is a common paperwork reason for an insurer query.
However, pre-operative imaging, such as ultrasound, a MAG3 renogram or a micturating cystourethrogram (MCUG), does not travel with the claim. Keep it on the patient record, because insurers may ask for it at audit or when they dispute authorisation.
Pro Tip
Build an operative note template for ureterocele excision with a separate field for each side. Fields for laterality, approach, reimplantation technique and imaging stop the note from leaving out the detail that separates M2511 from M2510.
Insurer pre-authorisation for CCSD Code M2511
M2511 is a major elective paediatric urology procedure, so UK private insurers, including Bupa, AXA Health, Aviva and Vitality, usually require pre-authorisation before elective surgery. A claim without an authorisation reference is one of the most common reasons insurers refuse an M2511 claim.
- Contact the insurer before the theatre date. Each insurer runs its own pre-authorisation portal or phone line for consultants and billing teams.
- Submit the proposed CCSD code and diagnosis. Give M2511 as the procedure code and Q62.3 as the ICD-10 code, plus any supplementary diagnoses.
- Provide the clinical evidence. Most insurers want the consultant’s outpatient letter, the imaging reports and the reason for open or laparoscopic excision over endoscopic treatment.
- Record the authorisation reference. It must appear on the claim, or the insurer will not pay.
- Check the authorised scope. Insurers grant authorisation for specific codes. A heminephrectomy added on the day may need a further request, and retrospective approval is at the insurer’s discretion.
In addition, the anaesthetist usually needs the same authorisation reference for their own invoice. Share it with them once you confirm the theatre list.
Policies change, so confirm current requirements with each insurer. The Bupa code search shows how Bupa treats each CCSD code for its members.
Insurer fees and complexity banding for M2511
CCSD publishes codes and descriptors, not prices. So it does not set a fee for M2511, and there is no national tariff for private procedures. Each insurer decides what it will pay for the code under its own fee schedule.
- Insurer fee schedules: Bupa, AXA Health, Aviva, Vitality and other insurers each publish the maximum surgeon fee they pay per CCSD code. The figure for M2511 differs between insurers.
- Complexity bands: Insurers and hospitals group codes into complexity bands, and the band shapes the fee and the hospital package price. Check the band each insurer assigns M2511 rather than assuming one.
- Shortfalls: If your fee exceeds the insurer’s limit, the patient may owe the difference. Agree this in writing before surgery, because some insurers restrict shortfalls for recognised consultants.
- Self-pay patients: Without insurance, the practice and hospital quote a package price directly. CCSD codes still help to itemise the invoice.
Therefore, do not quote a fee for M2511 from memory or from another insurer’s schedule. Check the current figure with the patient’s insurer before you send a treatment estimate.
Common denial reasons for M2511 claims
Insurers refuse M2511 claims for a familiar set of reasons. Each one maps to a check you can build into the workflow before submission.
When an insurer refuses a claim, read the insurer’s reason before you resubmit. Resubmitting without fixing the stated reason usually brings a second refusal.
Billing M2511 in private practice: Step-by-step
A structured workflow prevents the denial reasons above. These steps apply to most UK private insurer claims for M2511.
- Obtain pre-authorisation. Submit M2511 and the ICD-10 diagnosis to the insurer before the procedure date, and record the reference.
- Capture the operative note at the point of surgery. Confirm both sides, the approach, reimplantation status and anatomical findings, then get the surgeon’s signature.
- Confirm the code. Check the note describes excision on both sides. One side means M2510, and endoscopic treatment means M3202.
- Pair the diagnosis codes. Add Q62.3 as the primary diagnosis, plus Q62.5, Q62.6 or N13.7 where documented.
- Add concurrent procedures. List a heminephrectomy as its own line, M0380 or M0300, and check that the insurer authorised it.
- Submit the claim electronically. Most UK practices send insurer claims through Healthcode. Include the procedure date, your insurer provider number and the authorisation reference.
- Follow up unpaid claims. Track each claim against the insurer’s usual payment time and chase any that run over.
Anaesthesia and concurrent procedure coding
Surgeons perform M2511 under general anaesthesia, usually in children. The anaesthetist bills their own fee on a separate invoice, so the surgeon’s M2511 claim carries no anaesthesia element.
- Concurrent heminephrectomy: Bill M0380 or M0300 alongside M2511, chosen by approach. Each needs authorisation where the insurer approves codes separately.
- Diagnostic cystoscopy before excision: M2511 usually includes cystoscopy as a direct precursor to excision. Check the insurer’s bundling rules, because policies vary.
- Reimplantation: Reimplanting either or both ureters at the same sitting is already inside M2511. Do not add M2030 or M2080.
How Pabau keeps M2511 claims complete before submission
An M2511 claim depends on three records: the insurer’s authorisation reference, the signed operative note and the invoice. When those sit in a portal, a shared drive and a spreadsheet, a missing detail only shows up when the claim comes back.
Pabau, the practice management platform we build, keeps all three on the patient record. Your surgeons can build an operative note template with a field for each side. The coder then sees the laterality before choosing between M2510 and M2511.

Pabau’s claims management software tracks pre-authorisation status and sends insurer claims through Healthcode. It also shows which claims are still unpaid, so your team chases them before they age.

Manage CCSD claims across insurers from one place
Pabau helps private surgical practices track pre-authorisation, keep operative notes on the patient record and submit CCSD-coded claims through Healthcode. Your team spends less time chasing refused claims.

Conclusion
M2511 is a simple code to assign once the operative note proves excision on both sides. Claims fail on the paperwork around it: a missing authorisation reference, a note that names one side, or a US diagnosis code.
So make pre-authorisation a condition of booking theatre, and give surgeons a note template with a field for each side. That small step before surgery spares your team a round of corrections after it.

Frequently asked questions
What does CCSD Code M2511 cover?
CCSD Code M2511 covers open or laparoscopic excision of ureteroceles on both sides at the same operation, with or without ureteric reimplantation. The code already includes reimplantation at the same sitting. Excision on one side only takes code M2510.
Is ureteric reimplantation always included in M2511?
Reimplantation is optional, because the descriptor covers excision with or without it. When the surgeon reimplants either or both ureters at the same sitting, M2511 already includes that step. Do not add M2030 or M2080, and record in the operative note whether reimplantation took place.
What ICD-10 diagnosis codes pair with M2511?
On a UK claim, the primary diagnosis is Q62.3, other obstructive defects of renal pelvis and ureter, which includes congenital ureterocele. Add Q62.5, Q62.6 or N13.7 where documented. The codes Q62.31, Q62.32 and Q62.39 are US ICD-10-CM codes and are not valid on a UK claim.
Does M2511 need pre-authorisation from UK insurers?
Yes, in most cases. Bupa, AXA Health, Aviva and Vitality usually require pre-authorisation before elective surgery. Submit M2511 with the ICD-10 diagnosis and clinical evidence before the theatre date, and put the authorisation reference on the claim.
How does M2511 differ from M2510?
M2510 covers excision of a ureterocele on one side, and M2511 covers excision on both sides at the same sitting. Billing M2511 for a one-sided operation is up-coding. Billing M2510 twice for a bilateral operation is also incorrect, because CCSD has no bilateral modifier.
How much do insurers pay for M2511?
CCSD sets the code, not the fee. Each insurer publishes its own fee schedule and complexity banding, so the amount paid for M2511 differs between Bupa, AXA Health, Aviva and others. Check the current figure with the patient’s insurer before you send a treatment estimate.
