Key Takeaways
CCSD code 0011G is a UK private healthcare diagnostic code for genetic analysis of familial adenomatous polyposis (FAP), a specialist pathology test that examines the APC gene.
Familial adenomatous polyposis is an inherited condition that causes hundreds of colorectal polyps and, left untreated, a near-certain risk of bowel cancer, so an accurate APC gene result guides surveillance and family testing.
Because 0011G is a diagnostic test code rather than a procedure code, it is handled differently on insurer invoices, and each insurer sets its own fee and pre-authorisation rules.
Practice management software like Pabau helps UK private practices record the clinical indication, attach the laboratory report, and submit CCSD claims accurately without switching systems.
CCSD code 0011G is the UK private healthcare code for genetic analysis of familial adenomatous polyposis (FAP). It identifies a specialist pathology test that examines the APC gene for the inherited mutation behind FAP, an autosomal dominant condition that causes multiple adenomatous polyps in the colon and rectum.
The analysis looks for a germline mutation in the APC gene, a tumour suppressor gene on chromosome 5. A confirmed mutation explains a patient’s polyps, supports the FAP diagnosis, and lets the same mutation be checked for in relatives who may have inherited the same risk.
CCSD code 0011G: familial adenomatous polyposis genetic analysis
On the CCSD (Clinical Coding and Schedule Development) schedule, 0011G sits with diagnostic pathology and genetics tests rather than surgical procedures. Providers new to private practice management often meet CCSD codes for the first time when they set up insurer billing for laboratory and genetic work.
Individual CCSD narratives and current fees sit behind a registered login, so confirm the exact wording and reimbursement rate for CCSD code 0011G through the CCSD schedule or your insurer’s code portal before you submit.
What is familial adenomatous polyposis (FAP)?
Familial adenomatous polyposis is an inherited disorder that causes large numbers of adenomatous polyps to form in the large bowel, often from the teenage years. Classic FAP produces hundreds to thousands of polyps across the colon and rectum.
Left untreated, the lifetime risk of colorectal cancer approaches 100%, usually by around age 40. FAP is rare, affecting roughly 1 in 5,000 to 1 in 18,000 people, and it affects men and women equally.
FAP is passed down in an autosomal dominant pattern, so a child of an affected parent has a one-in-two chance of inheriting it. Some people have a milder form, attenuated familial adenomatous polyposis, with fewer polyps that tend to appear later in life.
The APC gene and what the analysis detects
The APC gene (adenomatous polyposis coli) is a tumour suppressor gene. When one copy carries a germline mutation, the brake it normally puts on cell growth in the bowel lining is lost, and polyps begin to develop.
Most FAP-causing changes are truncating mutations that shorten the APC protein. Laboratories detect them with DNA sequencing and add MLPA (multiplex ligation-dependent probe amplification) to pick up large deletions that sequencing can miss.
An APC gene mutation is found in roughly 60% to 80% of families with classic FAP. When a family’s specific mutation is already known, testing a relative is close to definitive. A negative result does not rule FAP out, so clinical surveillance continues either way.
Sometimes the laboratory reports an APC gene variant of unknown significance, meaning the change cannot yet be classified as harmful or harmless. These results need specialist interpretation before they guide care.
When APC genetic testing is used
Genetic analysis for FAP is usually requested after a colonoscopy shows a large number of adenomas, or when a patient develops an FAP-associated cancer. It is also offered to first-degree relatives of someone with a confirmed mutation.
- A colonoscopy showing more than 20 to 100 adenomatous polyps
- A personal or family history of FAP or early colorectal cancer
- Predictive testing for relatives of a patient with a known APC gene mutation
A result feeds directly into the patient’s care plan, from the timing of colonoscopy to decisions about colectomy, and into genetic counselling for the wider family.
How the CCSD schedule handles CCSD code 0011G
The CCSD schedule is maintained by the Clinical Coding and Schedule Development group and is the standard reference for private healthcare coding in the UK. Insurers including Bupa confirm they use CCSD industry-standard codes to identify clinical activity for reimbursement.
CCSD code 0011G is a diagnostic test code, not a procedure code, and that distinction changes how it is handled in practice.
- Diagnostic codes are handled separately from procedures. Under CCSD guidance, diagnostic test charges are not loaded into procedure code tables the way surgical procedures are. Confirm with your practice system administrator how 0011G should be configured for billing.
- CCSD sets the code, not the fee. The CCSD group defines the code narrative and its schedule chapter. Each insurer sets its own fee independently, so always check the insurer portal for the current rate.
- Pre-authorisation governs coverage. Whether a patient’s policy covers genetic testing is decided by the insurer at pre-authorisation, not by the code itself. Never assume coverage without written authorisation.
Genetic and molecular tests are often reviewed more closely than routine pathology, because policies differ on whether, and when, they fund inherited-disease testing. Providers leaving the NHS for private practice are frequently surprised by how insurer-specific these rules can be.
Documentation requirements for CCSD code 0011G
Clear documentation is what separates a paid genetic-testing claim from a denied one. For CCSD code 0011G, the supporting record should cover five areas.
All records linked to CCSD billing must be kept in line with UK GDPR obligations. Genetic test results are sensitive personal data, so store them with the same care as the rest of the clinical record. Notes supporting a claim should be retained for at least eight years for adult patients, consistent with NHS and Medical Defence Union guidance.
Pro Tip
Check that the sample collection or test date falls within the pre-authorisation window before you invoice. Many insurers reject claims where the service date sits outside the authorised period, even by a single day. Build a date-validation step into your workflow to catch this before submission.
Insurer-specific rules for CCSD code 0011G
Each major UK private medical insurer adds its own rules on top of the CCSD narrative, and genetic testing is an area where cover varies. The table below summarises how the four insurers most often billed with CCSD codes approach it.
Bupa billing rules
Bupa uses CCSD codes as its industry-standard billing framework for clinical activity in independent healthcare. Providers must hold Bupa recognition before submitting claims.
Bupa’s code search portal lets recognised providers confirm the exact narrative and fee for CCSD code 0011G. Genetic and molecular diagnostics may also need the test to be run by a recognised laboratory, so check both your recognition and the lab’s before submitting.
AXA Health billing rules
AXA Health bases its fee schedule on the CCSD schedule and publishes contracted rates for fee-approved specialists via the AXA Health portal. For genetic testing, confirm both your contracted status and whether the patient’s policy funds inherited-disease testing. Non-contracted providers may be reimbursed at a lower rate, leaving the patient to cover the shortfall.
Allianz Care billing rules
Allianz Care publishes a national UK Recognition Fee Schedule based on CCSD codes. For genetic and diagnostic tests, confirm whether the policy covers inherited-disease testing and whether the sample must go to a specific laboratory. Submit claims electronically where possible to reduce processing delays.
Aviva billing rules
Aviva requires providers to hold Aviva recognition before submitting claims, and bases its fee schedule for CCSD codes on the same CCSD framework as other UK insurers. For genetic and diagnostic tests, confirm the policy funds inherited-disease testing before the sample is taken, then submit CCSD code 0011G electronically via Healthcode.

Common CCSD code 0011G claim errors and how to avoid them
Most CCSD billing denials trace back to a small number of recurring mistakes. Practices using dedicated claims management software catch the majority before the claim reaches the insurer. Those relying on manual spreadsheets or generic invoicing tools tend to repeat the same errors.

- Wrong schedule context. Billing 0011G as a procedure when it is a diagnostic test leads to immediate rejection. Confirm the diagnostic classification before coding.
- Missing authorisation number. Every major UK PMI provider requires a valid pre-authorisation reference on the invoice. Without one, the claim is denied regardless of clinical accuracy.
- No clinical indication recorded. Genetic tests are routinely reviewed for medical necessity. A claim with no documented polyp count or family history is a common reason for query or denial.
- Non-recognised laboratory. If the APC gene analysis is run by a laboratory the insurer does not recognise, the claim can be refused even when the code is correct.
- Incorrect fee charged. Billing above the insurer’s contracted or recognised fee is the usual cause of patient shortfall disputes. Cross-check the fee against the current published schedule.
- Provider recognition lapse. Recognition must be current at the date of service. A lapsed status causes rejection even when the code and documentation are correct.
CCSD billing accuracy is a compliance function in its own right under most insurer contracts, and under UK GDPR where financial and health data meet. The same principles behind compliance for physiotherapy clinics apply just as much to genetic and diagnostic billing in UK private practice.
Pro Tip
Review your insurer recognition, and any recognised-laboratory list, once a year rather than waiting for a denial to arrive. Recognition lapses are rarely flagged in advance. Set a reminder for spring, when new CCSD fee schedules typically take effect, and check your status and rates at the same time.
How to submit CCSD code 0011G electronically
Electronic submission via Healthcode is the standard route for CCSD billing in UK private practice. Healthcode is the central electronic billing hub connecting private providers with all major insurers. Practices using practice management software that integrates with Healthcode can submit CCSD claims directly without re-keying data into a separate portal.
The electronic submission process for CCSD code 0011G follows four steps.
- Confirm pre-authorisation. Obtain the insurer’s written authorisation for the genetic test before the sample is taken. Record the reference number in the patient record.
- Generate the specialist invoice. Include CCSD code 0011G, the correct fee for the relevant insurer, the sample or service date, your GMC or GDC number, and the patient’s PMI membership number.
- Attach the laboratory report and clinical indication. Many insurers want the accredited laboratory’s APC gene result and the reason for testing. Check insurer guidance for 0011G specifically.
- Submit via Healthcode or the insurer’s portal. Bupa, AXA Health, and Aviva all accept electronic claims via Healthcode. Allianz Care accepts electronic submission via its provider portal. Keep a submission receipt for your records.
Practices running software for GP practices or specialist systems that do not connect to Healthcode natively can still submit electronically by uploading invoices through insurer portals. The key is matching the invoice data to the CCSD code narrative precisely to avoid automated rejection.

CCSD code 0011G and related genetic and diagnostic codes
CCSD codes do not exist in isolation. CCSD code 0011G sits alongside other genetic, diagnostic, and consultation codes, and knowing the boundaries between them prevents both under-coding and unbundling errors.
- Consultation codes (0001G series). The appointment where testing is discussed is coded and billed separately from the genetic analysis itself, so make sure both appear on the claim.
- Other inherited-cancer gene tests. FAP is not the only hereditary bowel-cancer syndrome. Testing for Lynch syndrome, linked to the HNPCC genes, or for MUTYH-associated polyposis uses its own codes, so match the code to the gene actually analysed.
- Diagnostic versus procedure schedules. As a diagnostic test, 0011G is handled differently from surgical procedure codes on insurer systems. Confirm which schedule governs the activity before you bill.
The CCSD Technical Guide is the authoritative reference for code relationships, chapter allocation, and billing conventions. Any practice regularly billing CCSD codes should keep a current copy accessible to its billing team. Providers focused on time-saving practice features often find that a well-configured template for each code family reduces cross-code errors.
Conclusion
CCSD billing denials rarely come from the science. They come from missing authorisation references, the wrong schedule context, and fee mismatches that a structured workflow would catch before submission.
CCSD code 0011G follows the wider CCSD pattern. The code identifies the FAP genetic analysis, the insurer sets the fee, and documentation quality decides whether the claim pays.
Practice management software like Pabau helps UK private practices build that workflow, linking patient records to invoices, flagging incomplete documentation, and tracking claim status across multiple insurers.

Familial adenomatous polyposis is an inherited condition that causes hundreds to thousands of adenomatous polyps in the colon and rectum, usually from the teenage years. Without treatment, the risk of colorectal cancer approaches 100% by around age 40. It is caused by a mutation in the APC gene and passed down in an autosomal dominant pattern.
APC gene analysis looks for a germline mutation in the APC gene, the tumour suppressor gene behind FAP. A mutation is found in roughly 60% to 80% of families with classic FAP. When a family’s mutation is already known, testing a relative is close to definitive, though a negative result does not rule the condition out.
Each private medical insurer sets its own reimbursement fee for CCSD code 0011G. The Clinical Coding and Schedule Development (CCSD) group defines the code narrative but does not set rates. Always check the relevant insurer’s published fee schedule before invoicing.
The most common reasons are a missing pre-authorisation reference, billing the code as a procedure rather than a diagnostic test, no recorded clinical indication for genetic testing, using a laboratory the insurer does not recognise, and charging above the contracted fee.
