CCSD code N1900 – Operation on varicocele

Key takeaways

N1900 covers open surgical ligation of a varicocele, through the inguinal (Ivanissevich) or retroperitoneal (Palomo) approach.

The approach decides the code. Laparoscopic varicocelectomy is N1910, microsurgical varicocelectomy is N1920, and percutaneous embolisation is XR442.

ICD-10 code I86.1 (scrotal varices) is the primary diagnosis pairing. N46 (male infertility) can support the claim as a secondary indication when a fertility workup is documented.

Each insurer applies its own bilateral rule, so two N1900 line items are not automatically payable at full fee.

Pabau’s claims tools hold the authorisation reference and diagnosis codes against each episode before the claim goes to Healthcode.

CCSD code N1900: Definition and clinical scope

CCSD code N1900 is the Clinical Coding and Schedule Development code for open surgical ligation of a varicocele. Its official descriptor is “Operation(s) on varicocele.”

It sits in chapter 12 of the schedule, which covers the urinary system and male reproductive organs. The other techniques have their own codes: laparoscopic varicocelectomy is N1910, and microsurgical varicocelectomy is N1920.

The schedule is maintained by the CCSD Group, which is governed by four private medical insurers: Bupa, Vitality, AXA Health and Aviva. No hospital providers sit on it. The schedule is updated periodically and serves as the reference for private healthcare billing in the United Kingdom.

Other UK private insurers, including WPA and Cigna, also map their procedure reimbursement schedules to CCSD codes. Our CCSD code library lists N1900 alongside the rest of the schedule, and the Bupa CCSD codes guide explains how Bupa applies it.

What N1900 includes

• Open inguinal ligation of the spermatic veins (Ivanissevich approach)
• Open retroperitoneal high ligation (Palomo approach)
• Other open surgical ligation or division of the varicocele veins, performed without laparoscopy or an operating microscope

What N1900 excludes

Three varicocele treatments have codes of their own and are never billed as N1900:

• Laparoscopic varicocelectomy: N1910
• Microsurgical varicocelectomy, including the subinguinal (Marmar) approach: N1920
• Percutaneous embolisation of the gonadal or spermatic vein, a radiological intervention: XR442

If a patient has surgical ligation and embolisation as staged procedures, each one needs its own CCSD code on a separate claim. Billing N1900 for a laparoscopic, microsurgical or embolisation procedure is a common coding error and a frequent cause of denial.

The procedure: What a varicocele operation involves

A varicocele is an abnormal dilatation of the pampiniform venous plexus within the spermatic cord. It most often affects the left side, because the left testicular vein drains into the left renal vein at a steep angle. Surgical correction occludes the abnormal venous channels so blood returns through normal venous drainage.

The surgical approach decides the CCSD code. N1900 applies only to the open approaches, and the laparoscopic and microsurgical operations each have their own code. The main approaches are:

• Inguinal (Ivanissevich), N1900: The surgeon makes an incision just above the inguinal ligament and ligates the spermatic veins proximal to the internal inguinal ring. It is commonly performed under general or regional anaesthesia.
• Retroperitoneal (Palomo), N1900: A higher ligation through a flank incision, used more often in paediatric cases.
• Laparoscopic, N1910: A three-port approach that reaches both sides in a single session, which matters when bilateral surgery is planned.
• Subinguinal microsurgical (Marmar), N1920: The spermatic cord is delivered below the external ring. An operating microscope helps preserve the testicular artery, lymphatics and vas deferens while the venous channels are ligated. It is considered the gold standard for minimising hydrocele risk.

The operative note must record the approach, the laterality, whether the testicular artery was preserved, and any intraoperative findings. The approach line matters most, because it tells the coder which code applies. The chart below maps each approach to its code.

Clinical indications and diagnosis codes

UK private insurers recognise a small set of clinical indications for N1900 reimbursement. Each maps to an ICD-10 diagnosis code that must accompany the claim.

UK insurers use the WHO edition of ICD-10, not the US ICD-10-CM, so the codes below are shorter than their US equivalents. A claim without a supported diagnosis code is usually rejected.

When male infertility is the primary indication, insurers typically ask for a semen analysis result and, where available, a fertility specialist’s referral letter. Some policies exclude infertility treatment altogether. Check the patient’s policy wording before submission, and document why surgery was chosen over conservative management.

Neighbouring CCSD codes and when to use them instead

Several CCSD codes are frequently confused with CCSD code N1900, and two of them describe the same operation done a different way. Selecting the wrong code typically results in underpayment or outright denial, even when the clinical documentation is strong.

A varicocele operation and a hydrocele repair in one session may go on separate line items. Each insurer’s unbundling rules decide it. Check the current Bupa schedule and the other insurers’ tables before coding a combined procedure, because unbundling policies differ.

Epididymal surgery has codes of its own too. Excision of an epididymal cyst bills as N1580, and a unilateral epididymectomy as N1520. Older code lists may also still carry CCSD code N0930 for an abdominal undescended testis, though it has been inactive since January 2009. Fixing both testes in the scrotum in one operation is a bilateral orchidopexy, billed under CCSD code N0820.

Bilateral procedures: Can N1900 be billed twice?

N1900 can be billed for both sides, but how depends on the insurer’s bilateral procedure policy. Bilateral varicocele is less common than a one-sided presentation. When a surgeon operates on both sides in one session, that policy sets the line items and the fee.

UK private insurers share no single rule. Each one says whether bilateral procedures go in as two line items at full fee, or with a reduced payment for the second side. The three largest handle it this way:

• Bupa: Bupa may apply a reduction to the second procedure when the same code is billed twice in one session. Confirm the current rule with Bupa’s provider team before billing, and include a clinical note confirming bilateral pathology.
• AXA Health: Bilateral rules sit in its specialist procedure codes schedule. Confirm the second-side reduction and the submission method before each episode, rather than relying on the last one.
• Aviva: Bilateral rules are set out in its procedure fee schedule. A pre-authorisation request for a bilateral procedure must state the planned laterality, or the claim risks a retrospective denial.

Bilateral rules are payer-specific and change periodically. State the laterality in the pre-authorisation request, and confirm the expected payment basis before the procedure takes place.

Pre-authorisation requirements for varicocele surgery

Most UK private insurers require pre-authorisation before they pay an N1900 claim. Not every policy demands it. Where a policy does, a claim sent without authorisation is denied, however strong the clinical case.

A pre-authorisation request for N1900 should carry four details:

• The scrotal ultrasound findings, including venous diameter and grade
• The duration of symptoms
• The proposed surgical approach
• The planned laterality

If male infertility is a co-indication, attach the semen analysis report too. An incomplete package is the most common reason an authorisation decision is delayed.

Because the approach sets the code, the request should name the planned code as well as the approach. If the surgeon changes approach, ask the insurer to amend the authorisation to N1910 or N1920 before the claim is sent.

Documentation required to support a valid N1900 claim

A complete N1900 claim needs documents from before, during and after surgery. A missing document at any stage can delay payment or prompt the insurer to ask for more information.

1. Pre-operative documentation: The specialist referral letter confirming the indication, and the scrotal ultrasound report with venous diameter and grade. Add the semen analysis where fertility is a stated indication. Include the pre-authorisation reference, and a consent form recording the planned procedure and laterality.
2. Operative note: The surgical approach, the laterality (left, right or bilateral), and whether the testicular artery and lymphatics were preserved. It also lists the ligatures placed and any intraoperative findings, including unexpected pathology. Complete it on the day of surgery.
3. Diagnosis coding: Primary ICD-10 code (typically I86.1) with any secondary codes attached to the claim. The diagnosis code must match the indication documented in the operative note.
4. Anaesthetic code: Where a separate anaesthetist bills, the CCSD anaesthetic code goes on its own claim. It never shares the surgeon’s N1900 line item.
5. Post-operative letter: A discharge or follow-up letter confirming the procedure went as planned, with any complications noted. It helps when a claim is queried later.

Digital consent and clinical note forms can capture laterality, approach and intraoperative findings at the point of care. The coder then works from a complete record, instead of chasing the surgeon for the missing approach line.

Common claim denials for N1900 and how to resolve them

N1900 denials follow a predictable pattern, and most can be prevented before submission. The table below sets out the most frequent reasons and the fix for each.

Fee guidance and surgeon’s schedule for N1900

CCSD code N1900 fees are set by each insurer independently and are not published as a single national rate. Consultants in independent practice also set their own self-pay fees, which typically exceed insurer reimbursement rates.

Key sources for current N1900 fee information:

• Bupa: The Bupa consultant schedule is accessible via the Bupa code search portal. Bupa’s 2026 reference lists N1900, N1910 and N1920 in the same band, Intermediate 2, at £286 each. Fees are updated periodically and differ between recognised and non-recognised consultants.
• AXA Health: The AXA Health specialist procedure codes schedule lists CCSD-mapped fees by chapter. Access requires an AXA Health provider registration.
• Aviva: Fee information for N1900 is published in the Aviva fee schedule for providers. Aviva applies standard CCSD coding but may require additional clinical evidence for infertility-linked claims.
• Healix: Healix is not an insurer. It is a third-party administrator that handles claims for some schemes, and it publishes its own CCSD-based fee table on the Healix fee schedule portal.

Confirm the current rate in the relevant insurer’s schedule before quoting any pound figure for N1900. Fees are revised annually and vary by insurer and by level of consultant recognition.

Some insurers also grade the three varicocele operations differently. National Friendly, for example, grades N1900 as Intermediate but N1910 as Major.

Our guide to the Bupa fee schedule explains how to read and apply Bupa’s published rates.

Billing N1900 on Healthcode and practice management systems

Healthcode is the main electronic billing and remittance platform UK private providers use to send CCSD claims to insurers. Most UK private insurers, including Bupa and AXA Health, accept it as the standard electronic route for consultant procedures.

The workflow for submitting N1900 on Healthcode follows these steps:

1. Patient episode creation: Open a new episode for the patient, confirming the insurer name, membership number, and policy number. These must match the details on the pre-authorisation approval exactly.
2. CCSD code entry: Search for N1900 by code or by the descriptor “varicocele.” Use N1910 or N1920 instead if the operative note records a laparoscopic or microsurgical approach.
3. Diagnosis attachment: Attach the ICD-10 diagnosis code (I86.1 as primary; N46 or N50.8 as applicable secondary codes). Some insurer portals validate the diagnosis code against an approved list at this stage.
4. Authorisation reference: Enter the pre-authorisation reference the insurer issued. A missing or wrong reference is the most common technical reason Healthcode rejects a claim outright.
5. Fee entry: Enter the agreed fee or the insurer’s scheduled rate for N1900. For a bilateral procedure, apply that insurer’s second-side rule before submission.
6. Submission and remittance: Submit the claim electronically and monitor the Electronic Remittance Advice (ERA) for payment confirmation or query notification.

How Pabau keeps varicocele claims clean from pre-auth to payment

Most urology practices run an N1900 claim across three places. The authorisation sits in an insurer email, the approach sits in the operative note, and the claim is keyed into Healthcode by hand. Every hand-off is a chance to send the wrong code or a missing reference.

Pabau, the practice management platform we build, keeps those pieces on the patient’s episode. Its claims management tools store the authorisation reference, attach ICD-10 codes from a saved list, and send the claim through Healthcode.

Claim status then comes back to the same record. Your team sees a query on a bilateral claim the day it arrives, rather than at month-end reconciliation.

Manage CCSD billing from pre-auth to payment in one place

Pabau helps UK private urology practices attach diagnosis codes, authorisation references and operative notes to each claim before submission. That cuts the back-and-forth that delays payment.

Conclusion

Code N1900 from the operative note, never from the theatre list. If the note says open inguinal or retroperitoneal ligation, N1900 is right. If it says laparoscope, microscope or embolisation, it is not, whatever was booked.

Bupa pays the three surgical codes at the same rate, so a wrong code rarely costs money up front. It costs time, because the claim comes back and the authorisation may need amending. Settle the approach and the laterality before the pre-authorisation request goes out, and most of the denials in this guide never happen.
