CCSD code 64302 – Transoesophageal echocardiography as sole procedure

Key Takeaways

CCSD 64302 covers TOE including reporting only when performed as the sole cardiac procedure

Reporting is bundled into the fee; billing a separate reporting code is unbundling and will be denied

Use 64301 instead when TOE accompanies another cardiac procedure in the same session

Pre-authorisation, a written clinical report, and a documented indication are required by most private insurers

CCSD Code 64302: definition and official descriptor

CCSD Code 64302 is defined as: Transoesophageal echocardiography (including reporting) (as sole procedure). That descriptor, maintained by the Clinical Coding and Schedule Development Group, contains three pieces of information that directly affect billing decisions.

• Transoesophageal echocardiography: the specific imaging modality, not transthoracic echo or stress echo.
• Including reporting: the written procedure report is covered within this fee. A separate reporting code must not be billed alongside it.
• As sole procedure: the code applies only when TOE is the only cardiac procedure performed. If the cardiologist performs a cardioversion or a right-heart catheterisation in the same session, the companion code 64301 applies instead.

The CCSD technical guide sets out the business rules governing how codes in the schedule interact. Coders should read the technical guide alongside the code schedule itself, because the descriptor alone does not capture all bundling and sequencing conventions.

What the TOE procedure involves

A transoesophageal echocardiography (TOE) procedure involves passing a flexible probe fitted with an ultrasound transducer into the patient’s oesophagus via the mouth. Because the oesophagus lies directly behind the heart, the TOE probe produces higher-resolution images of posterior cardiac structures than a standard transthoracic echocardiogram, making it the preferred modality for several specific indications.

The typical procedure sequence runs as follows:

1. Patient preparation: fasting for at least four hours, consent obtained, baseline observations recorded, IV access established.
2. Sedation or topical anaesthesia: conscious sedation or throat spray is administered to allow comfortable probe insertion. Sedation is a co-procedure and is not included in CCSD 64302.
3. Probe insertion and image acquisition: the consultant cardiologist advances the probe into the oesophagus and acquires imaging planes across the cardiac structures of interest.
4. Recovery: the patient recovers in a monitored area until sedation effects have cleared and observations are stable.
5. Reporting: the cardiologist produces a written report interpreting the findings. This report is included within CCSD 64302 and must not be separately billed.

Clinical indications for TOE

Private insurers require that the clinical indication for TOE is documented clearly in the patient record before authorising CCSD 64302. The British Society of Echocardiography (BSE) and the British Heart Rhythm Society (BHRS) both publish guidance that defines appropriate indications. For billing purposes, the indication justifies the procedure and forms part of the medical necessity argument if a claim is queried. Common indications include:

• Valvular heart disease: detailed assessment of the mitral, aortic, tricuspid, or pulmonary valves, including stenosis, regurgitation, and prosthetic valve function.
• Atrial fibrillation cardioversion: exclusion of left atrial thrombus prior to cardioversion, an indication specifically referenced in BHRS guidance on TOE for cardioversion.
• Infective endocarditis: detection of vegetations, perivalvular abscesses, or fistulae when transthoracic echo is inconclusive.
• Aortic pathology: assessment of the thoracic aorta for dissection, aneurysm, or intramural haematoma.
• Source of embolism: investigation of the left atrial appendage or interatrial septum following an embolic stroke.
• Intraoperative monitoring: cardiac surgery cases where continuous TOE monitoring is performed (note: intraoperative TOE is a different context and may attract different CCSD coding).

Documenting the indication before the procedure, rather than retrospectively, strengthens the claim and reduces the risk of insurer challenge.

What is and is not included in CCSD 64302

The table below sets out what the 64302 fee covers and what must be coded and billed separately. Misunderstanding the inclusions and exclusions is a frequent source of unbundling errors.

CCSD 64302 vs 64301: choosing the right code

The most consequential coding decision for TOE in private cardiology is whether to use 64302 or 64301. The wrong choice either overstates the procedure (if 64302 is billed when another cardiac procedure was also performed) or understates it (if 64301 is billed for a standalone TOE at a lower fee). Both errors carry claim-denial risk and, in the case of overbilling, compliance risk.

The practical decision rule: check the procedure record before coding. If the cardiologist’s notes confirm only TOE was performed in that session, 64302 is correct. If the notes confirm TOE plus a cardioversion, ablation, or other cardiac intervention, 64301 applies to the TOE component.

Related CCSD echocardiography codes in the 64000 series

The CCSD echocardiography range includes several codes near 64302. Knowing where 64302 sits in the family helps coders identify the correct code when the procedure differs from a standard diagnostic TOE.

Always verify specific descriptors against the current CCSD schedule, which is updated periodically. Code descriptors and associated rules can change between editions.

Billing CCSD 64302 to private insurers

UK private insurers including Bupa, AXA Health, Aviva, and Vitality all use the CCSD schedule as the basis for their fee structures. Each insurer applies its own benefit schedule on top of the CCSD code set, so the reimbursable fee for 64302 varies. Do not publish or quote specific fee amounts to patients; direct them to their insurer’s member portal or to the practice’s agreed fee schedule. For practice managers handling private practice management, understanding the submission workflow is as important as knowing the code itself.

• Pre-authorisation: most private insurers require pre-authorisation for TOE before the procedure is performed. The authorisation must reference the CCSD code (64302), the clinical indication, and the named consultant. Performing the procedure without authorisation is a common reason for denial even when the code is correct. Check each insurer’s current policy; requirements differ between Bupa, AXA Health, Aviva, and Vitality and may change.
• Submitting the claim: the invoice submitted to the insurer must reference CCSD 64302, the date of service, the consultant’s name and GMC number, the facility or hospital, and the ICD-10 diagnosis code that documents the indication. Omitting the diagnosis code is a frequent administrative cause of delay.
• Fee schedules: Bupa publishes Bupa procedure fee schedules that consultants can access via the Bupa code search portal. Vitality publishes a procedure fee finder for registered providers. Healix publishes detailed CCSD fee schedule and unbundling guidelines that apply to the codes it covers.
• Consultant recognition: the performing consultant must hold recognition status with the insurer. A claim submitted by an unrecognised consultant will be declined regardless of the code accuracy.

For practices using Bupa CCSD procedure codes regularly, maintaining an accurate list of the consultant’s recognition status across each insurer prevents avoidable rejections. Review recognition status at least annually, as insurers update their approved consultant lists.

Documentation requirements for a valid TOE claim

A technically correct CCSD 64302 code will still be denied if the supporting documentation does not meet the insurer’s requirements. According to the British Society of Echocardiography (BSE), a valid TOE report should meet accreditation-level standards, including structured findings, measurements, and a clear clinical conclusion. Beyond the BSE reporting standard, private insurers typically require:

• Pre-authorisation reference number: must appear on the invoice. Claims submitted without the authorisation number are routinely rejected at the administrative stage.
• Clinical indication documented in the notes: the patient record must state the reason for the TOE before the procedure date. Retrospective insertion of an indication is a red flag in insurer audits.
• Signed consent: written consent for the procedure (and separately for sedation if applicable) must be present in the clinical record. Practices should use digital consent and documentation forms that are time-stamped and patient-signed to satisfy both clinical governance and insurer audit requirements.
• Written procedure report: the cardiologist’s written echo report must be in the record. Since CCSD 64302 includes reporting in its fee, the absence of a report undermines the claim entirely. BSE accreditation standards provide guidance on what a complete report should contain.
• Images archived: echo loop and still images should be archived in the patient record or imaging system. Some insurers request image evidence during post-payment audits.
• Consultant letter: a clinic letter to the referring physician summarising the findings and clinical management plan is standard practice and supports the narrative of medical necessity.

Practices operating from CQC-registered facilities in England should be familiar with CQC registration requirements for procedure documentation, as CQC inspection findings can be used by insurers to assess the clinical governance standard of a facility. Understanding UK data protection and GDPR compliance is also relevant when storing echo reports and images, given the sensitive nature of cardiac imaging data.

Common reasons CCSD 64302 claims are denied

Denial patterns for 64302 cluster around a small number of recurring errors. Understanding these helps practice managers build a pre-submission checklist that catches most issues before the claim leaves the practice. Robust managing a medical practice workflow includes a systematic claim review step rather than treating denials as unavoidable.

• Wrong code selection (64302 vs 64301): billing 64302 when a concurrent cardiac procedure was also performed is the most common coding error. Insurers cross-reference the procedure list in the clinical notes against the billed codes during audit. If a cardioversion appears in the notes but 64302 is billed, the claim will be queried.
• Missing or expired pre-authorisation: performing the TOE before authorisation is confirmed, or using an authorisation number that has expired, results in automatic denial at most insurers. Pre-auth is procedure-specific and date-limited; always confirm validity before booking the patient.
• Unbundling the reporting fee: billing a separate reporting code alongside 64302 is a coding error because the descriptor explicitly includes reporting. Insurers running code-edit checks will reject the secondary reporting code.
• Insufficient clinical documentation: claims supported by a brief or missing procedure report, or where the indication is absent from the pre-procedure notes, are vulnerable to challenge during insurer review and audit.
• Consultant not recognised: as noted above, recognition gaps are an administrative denial cause that has nothing to do with code accuracy. Keep recognition records current.
• Duplicate billing: submitting the same claim twice, or billing both 64301 and 64302 for the same session, triggers duplicate-claim edits and will be denied.

Billing sedation alongside CCSD 64302

Conscious sedation or topical anaesthesia is routinely administered for TOE, but sedation is not included within CCSD 64302. This creates a legitimate opportunity to bill the sedation component separately, provided it is done correctly. Getting this wrong is one of the more common unbundling pitfalls in cardiology billing.

The correct approach depends on who administers the sedation and which insurer is being billed:

• Cardiologist-administered sedation: where the consultant cardiologist administers conscious sedation without a separate anaesthetist, the appropriate CCSD sedation code should be billed alongside 64302. Confirm the applicable code against the current CCSD schedule, as sedation codes are updated.
• Separate anaesthetist: when a consultant anaesthetist is present and administers sedation or general anaesthesia, the anaesthetist bills separately under their own CCSD anaesthetic codes. The cardiologist bills 64302 for the TOE component.
• Insurer-specific rules: coverage for separately billed sedation varies by insurer and by policy type. Some policies cover conscious sedation as part of the procedure benefit; others require a separate pre-authorisation. Always verify with the specific insurer before billing sedation separately.
• Topical anaesthesia only: throat spray or topical anaesthesia without sedation is not billed as a separate anaesthetic code. It is part of the procedure setup.

Never assume that sedation coverage transfers automatically between insurers. A Bupa-covered patient and a Vitality-covered patient in the same clinic may be subject to different sedation billing rules.

How Pabau supports CCSD billing for cardiology practices

Cardiology practices billing multiple CCSD codes per patient encounter need a system that reduces the manual overhead of code lookup, invoice construction, and insurer submission. Pabau’s claims management software includes a built-in CCSD code library, so 64302 and its related codes are available for selection within the invoicing workflow without requiring staff to maintain a separate code reference spreadsheet.

Key capabilities that reduce coding errors and administrative time for cardiology teams:

• CCSD code library built in: codes including 64302 and 64301 are searchable within Pabau’s invoicing module. Staff do not need to cross-reference external code books during billing.
• Invoice automation: once the procedure is recorded in the patient record, Pabau can generate a draft invoice populated with the CCSD code, date of service, consultant details, and diagnosis. This reduces transcription errors that cause administrative denials.
• Pre-authorisation tracking: Pabau allows pre-authorisation numbers to be recorded against each appointment, so the claim cannot be submitted without the relevant authorisation reference.
• Digital consent and documentation: Pabau’s digital forms capture signed patient consent with timestamps, satisfying the documentation requirements that insurers check during audit.
• Private GP and clinic workflows: the platform is designed for private GP and clinic software environments, including specialist cardiology practices billing to multiple insurers simultaneously.

For practice managers looking to reduce time spent on billing administration, Pabau’s time-saving features for private practices cover how automated invoicing and insurer integrations reduce the manual steps between procedure completion and claim submission.

Conclusion

CCSD Code 64302 is a straightforward code when the procedure is genuinely performed as a sole procedure, but claim denials cluster around the 64302/64301 distinction, missing pre-authorisation, and unbundled reporting fees. Getting the code selection right from the outset, documenting the indication before the procedure, and confirming each insurer’s pre-auth requirements eliminates the majority of preventable rejections.

Pabau’s built-in CCSD code library and pre-authorisation tracking help cardiology practices build these checks into the standard billing workflow rather than relying on individual staff knowledge.
