CCSD code K1800 – Placement of valve to cardiac conduit

Key takeaways

CCSD code K1800 covers placement of a valve to a cardiac conduit, under Heart – Cardiac Surgery in Chapter 8.

The CCSD record carries an inactive date, so confirm the code is payable with the insurer before surgery.

K1850, K3500 and 64302 are unacceptable combinations with K1800, so keep them off its claim.

A matching authorization and an operative note that describes a placement carry most of the claim.

CCSD code K1800 covers a valve fitted into a cardiac conduit

CCSD code K1800 is the code for placement of valve to cardiac conduit. Cardiac surgeons bill it to UK private medical insurers when they fit a valve into a heart conduit. CCSD stands for Clinical Coding and Schedule Development, the group that sets the codes insurers use.

A cardiac conduit is a tube that carries blood between the heart and a major vessel. Surgeons often place one during congenital heart repairs. The valve inside it stops blood flowing backward, and K1800 covers fitting that valve. Replacing the heart’s own aortic valve is a separate operation, coded K2600.

The code sits in Chapter 8 of the schedule, Thorax and intra-thoracic organs, under Heart – Cardiac Surgery. Its earlier narrative read “Creation of valved cardiac conduit.” Older insurer documents may still use that wording.

Check that K1800 is still live before you bill it

The CCSD record for K1800 shows an inactive date of January 1, 2006. Yet the same record lists combination rules created in January 2010. From the record alone, its current status is unclear.

Make status the first check on every K1800 case. Ask the insurer whether the code is payable on the patient’s policy before you request authorization. If they name another code, record it alongside their reference number.

CCSD schedule searches sit behind a login. Practices with an account can confirm the entry there. Others should rely on the insurer’s own code lookup. Our CCSD codes library covers neighboring cardiac procedures too.

Three codes can’t share a claim with K1800

The CCSD record lists three unacceptable combinations for K1800. Each one blocks a pairing that would charge for overlapping work.

• K1850: revision placement of valve to cardiac conduit. Pick one of the pair, based on whether the operation places or revises the valve.
• K3500: therapeutic transluminal operation(s) on valve of heart. This covers catheter-based valve work and can’t appear on a K1800 claim.
• 64302: transoesophageal echocardiography as a sole procedure. Echo imaging during the valve surgery isn’t added on top of K1800.

An unacceptable pair on the claim invites a query. Remove it before the claim leaves the practice, rather than after a rejection.

How a K1800 claim moves from surgery to payment

Cardiac cases run over weeks, so each step needs its own record. The diagram below pairs each step with the check that protects it.

1. Confirm cover and status: at referral, check the policy covers the surgery and that K1800 is payable.
2. Request authorization: send K1800, the diagnosis and the planned date. Save the authorization number to the patient record.
3. Review the operative note: after surgery, check it names the conduit, the valve and the placement.
4. Build the claim: add K1800, the matching ICD-10 diagnosis, the authorization number and the date of service.
5. Submit electronically: send it through Healthcode, or the insurer’s own portal where your practice uses one.
6. Track and respond: answer any insurer query with the operative note, within the insurer’s deadline.

The anesthesiologist bills separately, under their own codes. Their fee never belongs on the surgeon’s K1800 claim.

Before you submit: The five-point check

Run these checks on every K1800 claim. Each one takes seconds and matches a common reason for a query.

• The insurer has confirmed K1800 is payable, and you noted who confirmed it and when.
• The authorization number on the claim matches the insurer’s approval.
• The operative note describes a valve placed into a conduit, not a revision.
• No K1850, K3500 or 64302 line appears on the same claim.
• The surgeon’s details, date of service and membership number match the insurer’s records.

Common K1800 mistakes, and the fix for each

Most K1800 problems start before the claim is built. Watch for these four.

• Billing a revision as K1800. If the note describes revising an earlier valve placement, code K1850 instead.
• Adding echo as a separate line. Keep 64302 off the claim, because CCSD lists the pair as unacceptable.
• Assuming the code is current. Confirm status at referral, given the inactive date on the record.
• Quoting a fee from memory. CCSD sets codes, not fees. Check the patient’s insurer schedule before you quote a price.

How Pabau keeps K1800 claims moving through Healthcode

A cardiac case can run for weeks between referral, authorization and surgery. Details retyped into a claim that late are where errors slip in.

Pabau, the practice management software we build, connects directly to Healthcode for UK private insurance billing. Claims are built from the patient record, so the code, authorization number and membership details carry across. Before you send, Pabau checks the required claim fields are complete.

After submission, you can follow each claim’s status and reconcile the payment against it. See how claims management in Pabau works. The result is fewer returned claims and one place to answer an insurer query.

Send cleaner CCSD claims to Healthcode

Pabau builds Healthcode claims from the patient record and checks required fields before you send. Your team spends less time chasing returned claims.

Conclusion

K1800 is a narrow code with one open question: whether the insurer still pays it. Settle that at referral, and the rest of the claim becomes routine.

After that, two habits matter most. Keep the three unacceptable pairings off the claim, and make sure the operative note describes a placement. Together, they prevent the queries that hold up cardiac claims.
