CCSD code 0455O: HSV-1 and 2 DNA NAAT test billing guide

Key Takeaways

CCSD code 0455O covers the herpes simplex virus (HSV) type 1 and 2 DNA nucleic acid amplification test (NAAT), a laboratory diagnostic test rather than a surgical procedure.

Reimbursement for CCSD code 0455O is set independently by each insurer (Bupa, AXA Health, Aviva, Allianz Care, Vitality), not by the CCSD Group itself.

Insurers expect clear documentation of the clinical indication, specimen details, and the laboratory report before they will pay a claim submitted under CCSD code 0455O.

Practice management software like Pabau helps UK private practices structure CCSD-coded invoices, track pre-authorization status, and cut down on coding errors before a claim goes out.

CCSD code 0455O is the billing code UK private insurers use for the herpes simplex virus (HSV) type 1 and 2 DNA nucleic acid amplification test (NAAT). It sits within the Clinical Coding and Schedule Development (CCSD) Schedule, the coding framework every major private insurer in the UK uses to price and process claims.

This guide covers what CCSD code 0455O is, which insurers accept it, what documentation you need to submit, how to avoid common billing errors, and how Pabau can help your practice bill this test accurately.

What CCSD code 0455O covers

CCSD code 0455O identifies the herpes simplex virus (HSV) type 1 and 2 DNA nucleic acid amplification test (NAAT) in the CCSD Schedule. It is a laboratory diagnostic test, not a surgical procedure. A clinician collects a specimen, a laboratory analyzes it, and the result confirms or rules out HSV-1 or HSV-2 infection.

Because the complete CCSD schedule is commercially sensitive and login-gated, practices should confirm the exact narrative for CCSD code 0455O through the CCSD schedule access portal or an insurer’s own code search tool, such as Bupa’s code search. The description here reflects the test’s clinical context based on published insurer fee schedules and CCSD technical documentation.

Confirming the exact test narrative

The CCSD Technical Guide (October 2025) sets out the coding conventions and business rules that govern how codes like 0455O should be applied, including which additional codes, if any, can legitimately be billed alongside it. Check this guide, or the relevant insurer’s fee schedule, before relying on a secondhand description of any CCSD code.

Who orders and performs this test

GPs, sexual health (GUM) clinicians, dermatologists, and gynecologists most commonly order the HSV DNA NAAT test, usually to investigate symptomatic lesions or confirm a suspected herpes diagnosis as part of a wider sexual health assessment. Related infections, such as those covered under ICD-10 code A55, are often screened for at the same time.

The ordering clinician collects the specimen, and a laboratory performs the NAAT analysis and reports the result back for the clinical record. Many insurers require pre-authorization before the test is ordered under a private policy, and skipping that step is a common cause of denial. For background on UK private billing more broadly, see the guide to running a private practice in the UK.

Insurer fee schedules and reimbursement

The CCSD Group does not set fees. Each insurer publishes its own schedule of benefits, and the reimbursement level for CCSD code 0455O depends on which insurer the patient holds a policy with, and any insurer-specific unbundling rules that apply.

The table below summarizes how the major UK insurers structure their CCSD-coded fee schedules for diagnostic and pathology tests. Pre-authorization requirements vary by insurer and by the patient’s specific plan, so always check the current terms rather than assuming a blanket rule.

Practices billing across multiple insurers should keep an up-to-date record of each insurer’s current fee schedule for codes like 0455O. Fees change at annual schedule reviews, and billing at an outdated rate creates reconciliation issues that slow payment. Pabau’s claims management software helps practices track insurer-specific billing rules and flag discrepancies before submission.

Documentation requirements for CCSD code 0455O

Insufficient documentation is the most common reason CCSD-coded claims get disputed or denied. For CCSD code 0455O, insurers typically expect the following to be in place before a claim is processed.

• Referral or test request: A referral from a GP or another appropriate clinician confirming the clinical indication for testing, along with the patient’s insurer details.
• Pre-authorization reference number: Confirmation from the insurer that the test has been approved, including the authorization number to be quoted on the invoice.
• Ordering clinician details: The ordering clinician’s name, GMC number, insurer recognition number, and registered practice address.
• Specimen details: The sample type, collection site, and collection date.
• Laboratory report: The result issued by the laboratory, including the result classification (positive, negative, or indeterminate).
• Procedure date and CCSD code: The invoice must state CCSD code 0455O with the correct specimen collection date. The code must match the laboratory request and report exactly.

Some insurers ask for the full laboratory report rather than a summary result before settling the claim. Check each insurer’s specific requirements before submission. Practices transitioning from NHS to private billing will find the transition easier with guidance on moving from NHS to private practice, which covers documentation workflows in more detail.

Data protection for HSV test records

Patient records created and stored in connection with CCSD-coded tests are subject to the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. The Information Commissioner’s Office (ICO) requires that clinical records are retained securely, accessed only by authorized personnel, and held for no longer than the retention period defined by NHS or clinical guidelines (typically a minimum of eight years for adult patient records).

Private practices billing under CCSD code 0455O should have a documented data retention and destruction policy. Pabau’s digital forms capture patient consent and clinical history in a structured, audit-ready format. For a practical compliance checklist, the UK GDPR checklist for healthcare providers covers the key obligations relevant to private practices.

How to submit a claim using CCSD code 0455O

Most major UK insurers now accept electronic invoice submission, either through their own provider portals or through practice management systems with direct insurer integration. Submitting claims electronically reduces processing time and creates a verifiable submission trail.

Step-by-step claim submission

1. Confirm pre-authorization: Before submitting, verify that the pre-authorization reference is current and has not expired. Most insurers issue time-limited authorizations tied to a specific test and date range.
2. Generate the invoice: Create an itemized invoice including CCSD code 0455O, the exact narrative from the insurer’s schedule, the specimen collection date, the ordering clinician’s details, and the pre-authorization reference number.
3. Attach supporting documents: Include or reference the referral or test request and the laboratory report. Some insurer portals require these to be uploaded at the point of submission; others accept them on request.
4. Submit via the insurer’s portal or EDI: Submit through the insurer’s designated channel. Bupa and AXA Health both operate provider portals with CCSD code validation at submission. Allianz Care provides its own submission guidance for registered providers.
5. Track the claim status: Follow up if no acknowledgement is received within five working days. Unacknowledged claims sometimes fail at the submission stage due to format errors rather than clinical disputes.

Practices that bill multiple insurers regularly benefit from a centralized claim tracking workflow. Pabau’s claims management tools are designed for exactly this scenario, giving practice managers a single view across outstanding, submitted, and paid claims regardless of which insurer is involved. If your practice is also navigating CQC registration requirements alongside private billing, the guide to the CQC’s regulatory role is worth reviewing alongside your billing workflow.

Common billing errors and how to avoid them

Claim denials for CCSD-coded diagnostic tests are frequently caused by a small set of avoidable errors. Spotting these patterns helps practices correct them before submission rather than after a denial.

Unbundling errors

Unbundling occurs when a test that should be billed as a single CCSD code is split across multiple codes to increase the invoice total. UK insurers actively audit for unbundling. If CCSD code 0455O covers the test itself, elements such as specimen collection or an associated same-day consultation should not be billed separately unless the insurer’s schedule explicitly permits it.

The CCSD Technical Guide provides detailed guidance on coding conventions and the circumstances under which additional codes may legitimately be applied alongside a primary test code.

Miscoding the test type

CCSD codes for laboratory tests are billed as ordered, not adjusted for complexity the way some procedure codes are. Submitting a different test code than what the laboratory actually performed, for example billing 0455O when a broader sexual health panel was run instead of the specific HSV NAAT test, is a common audit trigger. The laboratory report must match the code submitted.

Billing without a valid referral

Most insurers require the patient to have been referred by a GP or another appropriate clinician before a test like this is covered. Billing CCSD code 0455O without a supporting referral or request on file is a straightforward denial ground. This is especially relevant for patients who self-refer to a private practice for testing, where the insurer may question whether the test was medically indicated. The guidance on GP referral pathways in UK private healthcare covers the referral process in more detail.

Missing or outdated pre-authorization

Pre-authorization references have expiry dates. Performing the test after the authorization has expired, even if the original authorization was valid, means the insurer is under no obligation to pay. Always check the expiry date on the authorization confirmation before the test is booked.

CCSD coding principles that apply to this code

The CCSD Group publishes coding principles bulletins periodically, updating practitioners on changes to the schedule, new codes, and revisions to existing narratives. These bulletins are issued to registered CCSD users and are commercially sensitive. Practices should make sure they are subscribed to updates through the CCSD membership system.

Repeat and follow-up testing

A DNA NAAT test does not have a bilateral equivalent in the way a surgical procedure might, so bilateral coding rules do not apply to CCSD code 0455O. What comes up more often is repeat testing. A clinician might re-order the same test if an initial result was inconclusive, or if a patient presents with a new symptomatic episode weeks or months later.

Insurers may query a second claim for the same code within a short window, so the referral or request for each test should clearly state why it was ordered again. Other laboratory-based CCSD codes, such as CCSD code 0054S, follow the same principle: repeat billing needs its own clinical justification on file.

How CCSD code requests work

If a test or procedure does not have a suitable existing CCSD code, practices can submit a code request to the CCSD Group. Requests are reviewed by the group and, if approved, added to the schedule in a later update bulletin. This process typically takes several months, so practices performing novel or emerging tests should check the schedule regularly for new codes rather than defaulting to an approximate existing code.

Practices managing CQC registration alongside CCSD billing will find the CQC inspection checklist a useful compliance reference. For a broader view of private practice compliance requirements, Pabau’s compliance management tools support documentation, audit trails, and policy tracking across UK private healthcare settings. The Bupa procedure codes and fee schedule guide provides additional context on how CCSD codes map to Bupa’s specific billing requirements.

If your practice bills across other code sets too, the guides to CPT code 00215 and HCPCS code Q4104 walk through the same documentation discipline for anesthesia and wound-care billing. Pabau’s template library also covers structured documentation for non-diagnostic services, such as the AccuTite aftercare instructions template, if your practice offers a broader range of treatments.

Conclusion

Accurate use of CCSD code 0455O requires more than selecting the right code from the schedule. Pre-authorization, complete specimen and laboratory documentation, and insurer-specific submission requirements all need to be in place before the invoice is raised. Errors at any of these stages create delays, disputes, and write-offs that affect the practice’s cash flow.

Pabau’s insurer claims tracking software is built for UK private healthcare practices billing across multiple insurers. It helps teams structure CCSD-coded invoices correctly, track pre-authorization status, and flag documentation gaps before claims are submitted.
