CCSD code 64300 – Transthoracic echocardiography

Key takeaways

CCSD code 64300 covers a complete resting transthoracic echo, including 2D, M-mode and Doppler assessment, together with the written report.

Every 64300 claim needs a signed echo report and a documented clinical indication. Missing either is a leading cause of insurer rejection.

Bupa, AXA Health, Aviva and Cigna each set their own pre-authorisation rules, so check the insurer’s provider portal before the appointment.

64300 and 64302 (transoesophageal echo) are not billed for the same session without explicit insurer agreement.

Practice management software like Pabau checks membership numbers and authorisation codes before an echo claim goes to Healthcode.

What CCSD code 64300 covers

CCSD code 64300 is the procedure code for echocardiography (including reporting) as sole procedure, which in practice means a standard transthoracic echo (TTE). The code is maintained by the Clinical Coding and Schedule Development (CCSD) Group. UK private medical insurers use its schedule to recognise and pay for procedures.

Cardiologists submit 64300 for a cardiac ultrasound performed from the chest wall. The transducer stays outside the body, no sedation is needed, and the study produces a structured report on cardiac anatomy and function. The code sits in chapter 1 of the CCSD procedural schedule, alongside the other CCSD codes for investigations and consultations.

“As sole procedure” means 64300 is not coded in addition to another procedure in the same session. The descriptor is also deliberately broad. It covers the complete echo examination rather than its individual technical components. Billing Doppler studies or chamber assessments as separate lines unbundles work the code already pays for.

Consultants moving from NHS cardiology into private practice sometimes expect private billing to follow NHS tariff logic. It does not. Under the CCSD schedule, 64300 is one code for one complete procedure, with no sub-codes to build up.

What the code includes and excludes

A correctly billed 64300 claim covers a complete transthoracic echocardiographic examination. The table below sets out what is bundled within the code and what falls outside it.

Stress echocardiography assesses cardiac function during exercise or pharmacological stress. It bills as 20132 and never under 64300. If a cardiologist performs a resting TTE and a stress study in the same episode, each needs its own code. That combination usually needs insurer pre-authorisation before submission.

Documentation insurers expect with a 64300 claim

Insurers do not pay for procedures that the clinical record cannot substantiate. A 64300 claim needs the five elements below. A missing one leads to rejection, or to an information request that delays payment.

• Written echocardiography report: A structured report meeting the British Society of Echocardiography (BSE) minimum dataset. It includes LV function, chamber dimensions, valve findings and Doppler measurements, and it must be dated and signed.
• Documented clinical indication: The referral letter or clinical notes must state the symptoms or clinical rationale. Examples include exertional dyspnoea, suspected valvular heart disease or a family history of cardiomyopathy. Coverage decisions rest with the insurer, and a documented indication does not guarantee approval. Its absence, however, almost always triggers denial.
• Pre-authorisation reference number: Where the insurer requires pre-auth (see the next section), the authorisation number must appear on the claim form. Without it, automated processing declines the claim at the first check.
• Treating consultant’s GMC number: This standard claim form field identifies the responsible clinician. It must match the consultant named on the echo report, or the claim is rejected.
• Date of service and membership number: Use the patient’s correct insurer membership number and the date the echo was performed. That is not the date the report was typed or the invoice was raised.

Most claims go electronically through Healthcode, the UK clearing house for private medical billing. Healthcode validates the pre-auth reference and GMC number against insurer records before the claim reaches the payment team. Errors at this stage return an immediate electronic rejection, so capture the clinical indication during the consultation rather than after the scan.

Pre-authorisation requirements by insurer

Pre-authorisation rules differ by insurer and can change without public notice. The table below reflects general guidance from provider portals and known insurer practice at the time of publication. Always check the relevant provider portal before submitting a 64300 claim.

As a general rule, an echo that follows a GP or consultant referral for a new cardiac symptom needs authorisation before the scan. Retrospective authorisation requests are routinely declined. Build the pre-auth step into the patient pathway at booking, rather than chasing it after the appointment.

64300 vs 64302: transthoracic and transoesophageal echo

CCSD code 64300 covers transthoracic echocardiography, and 64302 covers transoesophageal echocardiography (TOE). In a TTE the transducer sits on the chest wall. In a TOE it is passed into the oesophagus under sedation or general anaesthesia to get closer images of the heart.

Billing 64300 for a TOE exposes the practice to claim recoupment, because the fees and procedural complexity differ materially.

If the clinical record shows a TOE probe was used, submit the claim as 64302. Choosing 64300 to make the bill look smaller is still a code selection error, and insurers treat it as one. Review the procedure note before coding. The chart below runs the same check as three questions, in the order a coder should ask them.

Related codes billed alongside an echo

Several CCSD codes regularly appear in the same episode as an echocardiogram. Knowing how each relates to 64300 prevents both under-billing and improper unbundling. The table below covers the most common neighbours in a private cardiology workflow.

A cardiology consultation on the same day as a TTE is among the most common same-day combinations in UK private cardiology. Both are billable as separate items, provided each is documented with its own clinical notes. The echo report does not replace consultation documentation, and the consultation note does not substitute for a written echo report.

Bundling rules for echo components

The CCSD schedule bundles echocardiography, so the 64300 fee covers the complete examination as one billable unit. Billing individual technical components separately is unbundling. It breaches insurer billing terms and can lead to claim recovery or exclusion from insurer recognition schemes.

These components are bundled within 64300 and must not be billed as separate line items alongside it:

• Colour Doppler imaging
• Spectral Doppler (pulsed wave and continuous wave)
• M-mode recording
• Tissue Doppler imaging where performed as part of the standard examination
• Left ventricular ejection fraction calculation
• Valve gradient calculations derived from the same session

Audit echo invoices periodically to confirm that no Doppler or sub-component line has been added to a 64300 claim. This is a known audit trigger for Bupa and AXA Health. The CCSD Technical Guide is the authoritative reference wherever bundling is ambiguous.

Why echo claims are denied and how to fix them

Echo claims fail for a small number of recurring reasons, and each has a specific corrective action. The table below maps each denial trigger to its fix, based on patterns reported across UK private medical billing. Missing pre-authorisation is among the most common triggers, though no published insurer data ranks denial reasons definitively.

Review denial patterns quarterly. When the same rejection reason keeps returning, fix the workflow step that causes it instead of appealing each claim.

How to submit and appeal a 64300 claim

Most UK private cardiology claims go electronically through Healthcode, the clearing house used by Bupa, AXA Health, Aviva, Cigna and other private medical insurers. The submission sequence is the same whichever insurer pays.

1. Verify pre-authorisation before the appointment: Confirm the insurer has issued a valid pre-auth reference number. Record it in the patient record as soon as it arrives.
2. Complete the echo and the report: Make sure the written report meets the BSE minimum dataset before creating the invoice. Never raise an invoice against an incomplete draft report.
3. Create the invoice with 64300 and the pre-auth reference: Enter 64300, the date of service, the pre-auth number and the cardiologist’s GMC number. Attach the echo report and the referral letter.
4. Submit through Healthcode or the insurer’s portal: Healthcode runs electronic validation before the claim reaches the insurer’s payment team. Correct any validation errors returned at this stage before the claim is queued for processing.
5. Monitor claim status and answer information requests promptly: Insurers may send a request for further information (RFI) within the first 28 days. Responding within the insurer’s stated window, typically 28 to 42 days, keeps the claim active. Missed RFI deadlines usually lead to automatic denial.

Appealing a denied 64300 claim

If a claim is denied, find the specific reason on the insurer’s remittance or rejection notice. Gather the corrective documentation and resubmit within the appeal window. Most UK private medical insurers allow 90 days from the denial date for a formal appeal. Appeals that include a cover letter from the treating cardiologist, explaining the indication and procedure type, succeed more often than bare resubmissions.

For persistent denials on a correctly coded and documented claim, the BMA’s private practice team gives guidance on escalation, including insurer dispute resolution. GMC guidance on private practice also sets out the consultant’s responsibilities for accurate invoicing.

How Pabau helps cardiology practices get echo claims paid

In many private cardiology practices, billing staff still copy membership numbers and pre-auth references from emails onto invoices by hand. Each retyped field is a chance for one of the rejections described above. Pabau’s claims software for cardiologists works from the patient record instead.

Add the patient’s insurer and policy to their record, and each invoice routes to the correct insurer automatically. Before submission, Pabau checks that membership numbers and authorisation codes are filled in correctly. That catches the most common 64300 rejection, where pre-auth was obtained but never recorded on the invoice.

Claims go directly to Healthcode with the invoice attached, so nobody enters the same claim twice. The claims dashboard then shows each claim’s live status, from submitted and processing through to paid or error. Your billing team can see which echo claims need attention before an insurer deadline passes.

Get echo claims right the first time

Pabau checks membership numbers and authorisation codes before your echo claims go to Healthcode, then tracks each claim through to payment. See how it works in a live demo.

Conclusion

Getting 64300 paid depends on decisions made before the invoice exists. Confirm the probe route and any stress component before choosing the code. Secure pre-authorisation at booking, and check that the signed report meets the BSE dataset before billing.

Practices that build those checks into the patient pathway spend far less time on resubmissions and appeals. The cost is a few extra minutes at booking and reporting, and the return is echo claims that clear the first time.
