CCSD code 20310 – Follow-up outpatient consultation

Key takeaways

CCSD code 20310 covers a follow-up outpatient consultation by a consultant-grade clinician within an active episode of care.

It is distinct from 20300, the initial consultation code, and confusing the two is the leading cause of denial.

A remote follow-up has its own CCSD code, 20365, so 20310 is not the code for a telephone or video review.

Pre-authorization, episode linkage and a dated clinical note are expected by Bupa, AXA Health, Aviva and Vitality Health.

Pabau submits CCSD claims through Healthcode with the patient, treatment and insurer details already filled in.

CCSD code 20310: Definition and clinical scope

CCSD code 20310 is the Clinical Coding and Schedule Development code for a follow-up outpatient consultation. It covers a subsequent face-to-face review by a consultant in an outpatient setting. That review has to fall inside the same authorized episode of care in which the initial consultation, code 20300, was billed.

The CCSD Group maintains the schedule this descriptor is drawn from, and your insurer’s portal carries the current wording. The code sits in the CCSD consultation family alongside 20300, 20320 and 20330. Like every CCSD code, it applies only to UK private healthcare billing, with no equivalent in the NHS tariff or in CPT coding.

What the 20310 fee covers

The 20310 fee pays for the consultation itself. That means the clinician’s time, the assessment, the management advice and the letter back to the referrer. It does not cover procedures, investigations or imaging performed at the same attendance. Those carry their own CCSD procedure codes, submitted alongside 20310 on the same claim.

Key scope boundaries to know before billing:

• Face-to-face requirement: 20310 describes an in-person review. CCSD publishes a separate code for a remote follow-up outpatient consultation, 20365, so a telephone or video review is coded there instead. Check each payer’s remote consultation policy before billing either code.
• Consultant grade: the clinician must hold consultant-grade registration with the GMC or the relevant professional body. A registrar or SHO seeing the patient independently cannot bill under 20310. Check your insurer’s recognition letter for its grade requirements.
• Episode linkage: the follow-up has to sit within an active, pre-authorized episode of care. A consultation after the episode has closed, or for a new and unrelated presenting problem, needs a fresh 20300 and new authorization.
• Not for an admitted patient: once the patient is admitted, day-to-day care by the treating consultant is coded 20320. A review by a second specialist, or a consultation in an emergency, is coded 20330.
• Procedures billed separately: injections, minor surgery or diagnostic tests performed at the same attendance require their own CCSD codes.

CCSD code 20310 vs 20300: Key differences

The most common coding error on follow-up claims is billing 20300 instead of 20310, or the reverse. Both codes cover a consultant-led outpatient consultation, but they are not interchangeable. 20300 is for the first assessment in a new episode of care, and 20310 is for every subsequent review inside that same episode.

Billing 20300 for a patient already inside an active episode is an over-claim. Any payer that cross-references episode history will reject it.

Related CCSD consultation codes

20310 sits in a family of six consultation codes, split by setting and by whether the review happens in person. The grid below shows which attendance takes which code. The wider schedule these sit in is indexed under CCSD codes.

If a patient who completed treatment under one episode returns months later with a recurrence, that visit needs a new 20300. The episode has to be open at the date of service for 20310 to be valid.

Documentation requirements for a 20310 claim

A 20310 claim is paid only where the documentation shows a consultant-led follow-up inside a live episode. Most rejections at the documentation stage are preventable, and the fix is usually a field nobody filled in.

Every 20310 claim should be supported by:

• A dated clinical note: the note records the date of the follow-up and the consultant’s name. It also records the reason for review, the clinical findings and the management plan. Most payers want the note available on request, and some ask for it to accompany the claim.
• Episode and authorization number: the claim has to reference the same episode number and pre-authorization reference issued when 20300 was billed. A mismatched episode number is one of the leading causes of automated rejection.
• Consultant identification: the billing name must match the recognized consultant on the insurer’s system. Where a locum or associate conducted the review, check with the payer whether the registered consultant can still bill under their own name.
• Date of service: the service date on the claim has to fall within the episode’s authorized period. A claim dated after the episode expired is denied even where the visit itself happened on time.

Digital consultation forms write the date, the clinician’s name and the episode reference straight into the patient record. That removes the commonest cause of a missing field at claim time. Practice management software like Pabau attaches the completed form to the encounter it belongs to, so the note and the claim never drift apart.

Which UK insurers accept 20310?

Every major UK private medical insurer accepts CCSD code 20310 as the standard follow-up outpatient consultation code. Pre-authorization requirements and episode limits differ between them, so confirm the specifics with each payer before billing. The table below covers the four largest UK private medical insurers, and their policies are revised periodically.

Vitality accepts digital invoices only and asks providers to submit through Healthcode, which is the same route the other three payers use.

How to submit a 20310 claim

Most UK private consultants submit CCSD claims electronically through Healthcode, the EDI billing network the major UK insurers share. The steps below describe a Healthcode submission, and a paper claim follows the same sequence.

1. Confirm pre-authorization before the appointment. Obtain an authorization number from the patient’s insurer. Record it on the patient’s record and confirm the episode is still open.
2. Complete the clinical note on the day of the consultation. Date it, sign it and record the episode reference. Do not submit the claim without a matching note.
3. Enter 20310 in your billing system. Populate the claim with the date of service, the consultant’s recognized name, the patient’s membership number and the authorization reference.
4. Add any co-billed procedure codes. Where an injection or minor procedure happened at the same visit, include those codes on the same claim. Never bundle a procedure fee into the consultation code.
5. Submit electronically through Healthcode. Review the submission confirmation and keep the Healthcode reference number. Most payers acknowledge receipt within 24 hours.
6. Track the claim until it settles. A query or a rejection appears on the Healthcode portal with a reason code, which tells you which of the conditions below failed.

Why 20310 claims get denied

Denial rates on follow-up consultation claims run higher than on initial consultations. 20310 depends on three things 20300 does not: a prior 20300 claim, an open episode and a valid pre-authorization number. Any one of the three can be wrong. The most frequent denial reasons are:

• No prior 20300 on file: the insurer holds no record of an initial consultation in the same episode. This happens where 20300 was never submitted, was itself denied, or was billed under a different episode reference.
• Expired episode of care: the authorized episode period closed before the date of the follow-up. The fix is to request an extension before the next appointment, rather than after the claim has been submitted.
• Missing or invalid pre-authorization number: the authorization reference on the claim does not match the insurer’s record. Check you are using the authorization for the correct episode and the correct patient.
• Clinician not recognized at consultant grade: the billing clinician does not appear on the insurer’s recognized specialist list. Payers will not reimburse a 20310 claim from a clinician whose recognition has lapsed or was never established.
• Duplicate claim: a claim for the same patient, date and code has already been processed. This occurs when claims are re-submitted without first checking whether the original was paid.
• Follow-up frequency limit reached: some insurers cap the number of follow-up consultations per episode. Verify the patient’s benefit limit before scheduling further follow-ups.

How to appeal a denied 20310 claim

The appeals route for a denied 20310 claim is broadly consistent across payers. It is also the first question a billing team faces after a rejection, and the sequence below is what usually resolves one.

1. Read the denial reason code carefully. Healthcode and most insurer portals return a specific reason code. Match it against the list above before doing anything else.
2. Gather your documentation. Pull the original pre-authorization confirmation, the clinical note dated on the day of service, and the prior 20300 claim reference for the same episode.
3. Write a concise appeal letter. State the authorization number, the service date, the denial reason, and how your documentation satisfies the code requirement. Attach copies, never originals.
4. Cite the payer’s own CCSD guidance. Reference the insurer’s current provider billing guide for 20310 specifically. Bupa’s code search portal and AXA Health’s specialist forms portal both publish their current position.
5. Submit within the insurer’s appeals window. Each payer publishes its own deadline, and missing it closes the claim permanently. Check that window before you start gathering documents.
6. Escalate if the first appeal fails. Ask for a formal review by the insurer’s medical director team. Where the decision turns on clinical judgment, a supporting letter from the treating consultant carries real weight.

Fees and reimbursement for follow-up consultations

Fee levels for CCSD code 20310 vary by insurer and are revised on each payer’s own schedule, usually once a year. No single published fee applies across all insurers, so check current rates against each fee schedule.

The structure is consistent, though: the 20310 rate sits below the 20300 rate, because a review is shorter than a first assessment.

Self-pay patients are billed at the consultant’s own published rate, which need not follow the insurer schedule. Many consultants set that rate slightly above it, since self-pay work carries none of the insurer-driven volume.

For verified figures, go to each payer directly:

• Bupa: the Bupa Code Search portal lists recognized procedure fees by code
• AXA Health: fee chapters are published through the AXA specialist forms portal
• Aviva: rates for recognized consultants sit in the Aviva fee schedule
• Vitality Health: consultation rates are looked up through the Vitality Fee finder

How Pabau builds a 20310 claim from the consultation record

Practice management software that connects to Healthcode removes most of the manual steps in a 20310 workflow. Instead of retyping the code, the episode reference and the consultant’s details into a portal, a connected system reads them from the patient record.

Pabau supports CCSD billing through its claims management software. Insurer details sit on the patient record, so a claim routes to the right payer and the patient, treatment and insurer fields arrive pre-filled.

Validation checks run in the background and hold the submission until required details such as the membership number and authorization code are present.

Every claim then sits on one dashboard, moving through pending, submitted, processing, paid or error, filterable by date, insurer or invoice ID. For a practice running a high volume of follow-up consultations, that replaces the spreadsheet usually kept alongside the portal.

Conclusion

CCSD code 20310 is simple in principle. Bill it for a consultant-led follow-up outpatient consultation inside an active, pre-authorized episode of care.

The errors cluster in three places: confusing 20310 with 20300, submitting without a valid authorization reference, and letting the episode lapse before the visit.

Getting those three right prevents most rejections before they happen, and it costs far less time than any appeal. Pabau links the consultation record to the Healthcode submission, so the claim carries what the payer asked for. Book a demo to see how it handles CCSD billing for a UK private practice.
