CCSD code K4410 – Revision coronary artery bypass


Code Definition

CCSD code K4410 covers revision bypass for coronary artery(ies), including harvesting of grafts. Cardiac surgeons bill it to UK private medical insurers for a repeat bypass on a patient who has had one before.

The detail that trips claims sits in the bracket. Graft harvesting is already part of K4410, so it never goes on the invoice as a second line. A first bypass takes a different bypass code instead. Below, we cover the codes that clash with K4410, what insurers check and how the claim moves through Healthcode.

Key takeaways

Key takeaways

CCSD code K4410 covers revision bypass for coronary artery(ies), and graft harvesting is already included in the code.

K4410 sits in Chapter 8 of the CCSD schedule, under sub-chapter 8.8.0 Heart – Cardiac Surgery.

Use K4410 for a repeat bypass operation only, since a first bypass takes a code such as K4100.

CCSD lists the bypass codes K4100, K4180 and K4600 and the catheterization code K6514 as unacceptable combinations with K4410.

Insurers check for a matching pre-authorization, an operative note that records the previous bypass, and a diagnosis code that explains the redo.

CCSD code K4410 covers revision coronary artery bypass

CCSD code K4410 is the code for revision bypass for coronary artery(ies), including harvesting of grafts. Cardiac surgeons use it to bill a UK private medical insurer for a repeat bypass operation. It describes the surgeon’s procedure, not the hospital stay or the theater team.

CCSD stands for Clinical Coding and Schedule Development. The CCSD Group brings together Aviva, AXA Health, Bupa and Vitality. It maintains one shared schedule of CCSD codes, so a procedure carries the same code at every insurer that uses it.

Here are the reference details for K4410 at a glance.

Field Detail
Code K4410
Official descriptor Revision bypass for coronary artery(ies) (including harvesting of grafts)
Chapter 8 Thorax and intra-thoracic organs
Sub-chapter 8.8.0 Heart – Cardiac Surgery
Nearest OPCS-4 code K44.2 Revision of replacement of coronary artery (nearest equivalent, not an official mapping)
Who bills it The operating cardiac surgeon
Fee Set by each insurer, not by the CCSD Group

The CCSD Group does not set fees or reimbursement. Its coding principles are also not exhaustive. Each insurer decides whether to adopt them, so the insurer’s own rules have the last word on any claim.

A redo bypass follows five main stages

A revision bypass is open-heart surgery on a patient who has already had coronary artery bypass grafting. The surgeon places new grafts to restore blood flow past failed grafts or newly diseased arteries. A typical operation runs like this.

  • Re-entry: The surgeon reopens the chest, usually through the previous sternotomy, taking care around scar tissue and any working grafts.
  • Graft harvest: New conduits are taken, such as a saphenous vein, a radial artery or an unused internal mammary artery.
  • Bypass: Most redo operations use cardiopulmonary bypass, although some surgeons work on the beating heart.
  • Grafting: The new grafts are sewn beyond the blocked segments, and failed vein grafts may be replaced or tied off.
  • Check and close: The team confirms graft flow and heart function, places drains and closes the chest.

Because graft harvesting is written into the descriptor, the vein or artery harvest is part of K4410. It never goes on the claim as a second line.

Patient history decides K4410 over a first-time bypass code

K4410 is for a repeat bypass operation. A first bypass takes a bypass code such as K4100, even when it uses several grafts. The patient’s history decides the code, not the number of grafts placed.

Treatment through a catheter is a different procedure with its own code. Balloon angioplasty takes K4900, and angioplasty with a stent takes K4910. The decision tree below shows how the three routes split.

Decision tree for coronary procedure codes
Two questions settle the code: has the patient had a bypass before, and were the new grafts placed in open surgery? Based on CCSD descriptors and K4410’s listed combinations.

Here’s how that plays out. Say a patient had a triple bypass eight years ago, and a new angiogram shows two blocked vein grafts. The surgeon reopens the chest, harvests a radial artery and places two new grafts. That operation is one K4410 line, with Z95.1 added to show the earlier bypass.

Redo bypass carries more risk than a first operation, and percutaneous treatment is often considered first. So an insurer reviewing a K4410 claim may ask why surgery was chosen. The operative note and the referral letter should answer that before anyone asks.

Common reasons include several failed vein grafts, disease in the left main stem and anatomy that does not suit angioplasty. A previous stent failure that cannot be treated again is another.

Bypass and catheter codes that stay off a K4410 claim

The CCSD principles page for K4410 lists codes that should not be claimed with it. That page sits behind a CCSD login, so we could only read its entries through a public search index.

Treat the table as a starting point and confirm each line in the CCSD schedule.

Code What it covers Listed relationship to K4410
K4100 Coronary artery bypass, including graft harvesting and endarterectomy Unacceptable combination (confirm in CCSD)
K4180 Robotic-assisted coronary artery bypass Unacceptable combination (confirm in CCSD)
K4600 Off-pump coronary artery bypass (OPCAB) Unacceptable combination (confirm in CCSD)
K6514 Adult cardiac catheterization, brachial access Unacceptable combination (confirm in CCSD)

Each entry has a clear reason behind it. A redo bypass already covers the grafting, so adding another bypass code would claim the same work twice.

The catheterization code K6514 is listed for a similar reason, as CCSD does not expect it on the bypass claim. The same listing also names K5020, K5050 and K6700, so check those entries in the schedule too.

Valve surgery in the same operation is a separate matter. It has its own code and its own line on the claim. Each insurer then applies its own rules on what it pays for a second procedure.

Diagnosis codes should explain why a redo was needed

The diagnosis code has to tell the same story as the operative note. These ICD-10 codes are the usual matches for a revision bypass.

Diagnosis ICD-10 code Billing note
Atherosclerotic heart disease I25.1 Name the native vessels and grafts affected
Unstable angina I20.0 Record the timing if the operation was urgent
Other forms of angina pectoris I20.8 Use when the angina type is documented
Other complications of cardiac and vascular prosthetic devices, implants and grafts T82.8 Use for graft stenosis or occlusion
Presence of aortocoronary bypass graft Z95.1 Add it to show the earlier bypass

UK insurers work with the WHO version of ICD-10. Confirm each code against the insurer’s accepted list before you submit.

Get pre-authorization before the operation date

Most UK private medical insurance policies require pre-authorization for planned inpatient surgery. The patient usually contacts the insurer, but the surgeon’s team supplies the clinical detail. A complete request carries these items.

  • The CCSD code K4410, plus the code for any second planned procedure
  • The ICD-10 diagnosis codes, including the earlier bypass
  • The planned date of surgery and the hospital
  • The consultant’s insurer recognition details
  • The latest coronary angiogram report and the heart team decision

Record the authorization number on the patient’s file as soon as it arrives. If the plan changes in the operating room, contact the insurer promptly. An authorization for one code does not cover another.

The operative note has to prove it is a redo

The operative note is the evidence behind the code. Insurers can request it before or after payment, so write it with the claim in mind. It should cover these points.

  • The date and type of the earlier bypass operation
  • The state of each previous graft found at surgery
  • The new grafts placed, with the target vessel for each one
  • The conduits harvested and where they came from
  • Whether the operation used cardiopulmonary bypass
  • Any other procedure performed, described on its own

How a K4410 claim moves through Healthcode

With the note signed, the invoice can go out. Healthcode is the electronic billing service most UK private insurers use for consultant invoices. Its bills reach the insurer faster than paper and are checked against insurer rules on the way. A K4410 invoice takes six steps.

  1. Open the patient’s episode and select the insurer.
  2. Enter the membership number and the pre-authorization number.
  3. Add K4410 as the procedure code, with the date of surgery.
  4. Add the ICD-10 diagnosis codes.
  5. Enter your fee and submit the invoice.
  6. Track the claim status and answer any query quickly.

Pro Tip

Send the K4410 invoice only after the operative note is signed. Then, if the insurer asks why a revision was needed, you can reply the same day with the note attached.

Run these checks before you submit

A quick review before the invoice leaves saves a round of insurer queries later. Work through this list on every K4410 claim.

  • The authorization number matches K4410 and the date of surgery.
  • Z95.1 sits on the claim, and the note describes the earlier bypass.
  • No other bypass code, catheterization code or graft harvest line sits beside K4410.
  • Any second procedure, such as valve surgery, has its own code and line.
  • The operative note is signed and names each new graft and its target vessel.
  • The membership number matches the one the insurer holds.

Common mistakes that stall K4410 claims

Even a careful team slips on the same few points. Each of these errors can stall a K4410 claim, and each one has a straightforward fix.

Mistake What to do instead
Using K4410 for a first bypass Bill the bypass code that matches the operation.
Adding another bypass code to K4410 Leave it off, because CCSD lists the pairing as unacceptable.
Billing graft harvesting as a second line Leave it out, because K4410 already includes it.
Adding a cardiac catheterization code to the bypass claim Leave K6514 off, since CCSD lists it as unacceptable with K4410.
Relying on an authorization that no longer matches Check the code and date again before the operation.
Leaving out the earlier bypass Add Z95.1 and describe the previous operation in the note.

How Pabau keeps K4410 claims ready for the insurer

A K4410 claim pulls paperwork from several places. The authorization letter sits in one inbox, and the angiogram report in another system. The details of the first bypass may be in an old discharge letter. When a query lands weeks later, someone has to find all of it again.

Pabau, the practice management platform we build for private consultants, keeps those documents on the patient record. Pabau’s claims management software sends the claim through Healthcode from the patient record.

Your team can also track each claim’s status and reconcile payments without leaving Pabau. When the insurer asks about the redo, the operative note is already on the same screen.

Send cleaner K4410 claims through Healthcode

Pabau keeps authorizations, operative notes and invoices on one patient record. It then sends CCSD-coded claims to insurers through its Healthcode integration.

Conclusion

K4410 is the right code when the patient has had a bypass before and the surgeon placed new grafts in open surgery. A first bypass, or a blockage treated through a catheter, belongs under a different code.

The code choice is rarely what holds up payment. Claims stall when a second bypass code stays on the invoice, or when the note never mentions the earlier operation. Fix both before submission, and the insurer has little left to query.

Frequently asked questions

Can K4410 be billed for a single new graft?

Yes. The descriptor reads coronary artery(ies), so one new graft or several bill as one K4410 line. The earlier bypass decides the code, not the graft count.

What does harvesting of grafts mean in the K4410 descriptor?

It means taking the vein or artery used to build the new bypass. That is usually a saphenous vein, a radial artery or an internal mammary artery. The harvest is part of K4410, so it is never billed separately.

Which OPCS-4 code is closest to K4410?

K44.2, revision of replacement of coronary artery, is the nearest OPCS-4 code. Treat it as the closest equivalent rather than an official mapping between the two systems.

How do CCSD codes differ from OPCS-4 codes?

OPCS-4 is the NHS classification for recording procedures in hospital data. CCSD codes are the schedule UK private insurers use for billing. A private hospital may record both for the same operation.

Who sets the fee for K4410?

Each insurer sets its own fee. The CCSD Group maintains the codes but does not set fees or reimbursement. Check the insurer’s schedule before you quote the patient.
