CCSD code C1420 – Graft of skin to eyelid

Key takeaways

CCSD code C1420 is the UK private medical insurance code for a graft of skin to eyelid, listed in chapter 4 (Eye and orbital contents).

Freedom Health Insurance pays C1420 as an Intermediate procedure, at £300 for the specialist and £213 for the anesthetist (January 2026).

Lid codes that already include a graft, such as C1513 and C1523, are billed instead of C1420, never alongside it.

Most UK private insurers expect pre-authorization before a planned eyelid graft, and the reference number belongs on the claim.

Pabau’s claims management software keeps the authorization reference, operative note and CCSD claim on one patient record.

What is CCSD code C1420?

CCSD code C1420 is the UK private medical insurance code whose official descriptor is “Graft of skin to eyelid.” It covers harvesting a skin graft and fixing it over a defect of the upper or lower eyelid.

The code sits in chapter 4 (Eye and orbital contents) of the schedule, in section 4.2, “Eyebrow and lid.” It belongs to the C-series of CCSD codes that ophthalmic and oculoplastic surgeons bill.

The schedule is maintained by the Clinical Coding & Schedule Development (CCSD) Group. Bupa, AXA Health, Vitality, Cigna, WPA and Aviva use it to invoice and reimburse private medical insurance claims across the UK. Each insurer then sets its own fee against the code.

The descriptor does not split full-thickness from split-thickness grafts. The operative note has to name the graft type, because insurers review it before they pay.

When is an eyelid skin graft performed?

An eyelid skin graft is used when a defect is too large to close directly or to repair with local tissue alone. The usual reasons for a C1420 procedure are:

• Basal cell carcinoma (BCC) excision: Periocular BCC is one of the most frequent indications. Wide excision can leave a defect that needs new skin, particularly along the lower lid.
• Squamous cell carcinoma and other eyelid cancers: Defects left after excision follow the same reconstruction logic as BCC.
• Cicatricial ectropion: Scarring from burns, trauma or earlier surgery pulls the lower lid away from the eye. A graft releases the scar and restores the lid position.
• Lid retraction after earlier surgery: Too much skin removed at an earlier eyelid operation can stop the lid from closing. A graft replaces the missing skin.
• Post-traumatic defects: Lacerations or avulsion injuries with skin loss that cannot be closed directly.
• Radiation damage: Periocular skin damaged by earlier radiotherapy may need a graft to rebuild a working lid.

Record the indication in the operative note alongside the ICD-10 diagnosis code. Insurers judge medical necessity from the diagnosis and the surgical plan together.

Insurers also check that the graft is reconstructive. Freedom’s chapter 4 notes say it does not cover blepharoplasty, which must not be coded as eyelid reconstruction. If a graft repairs a lid that cosmetic surgery left unable to close, write the functional problem into the notes.

How an eyelid skin graft is performed

Knowing the surgical steps helps coders check that the operative note supports a C1420 claim.

1. Recipient bed preparation: The surgeon cleans the defect and releases any scarring. The bed is then sized and shaped to take the graft with minimal tension.
2. Donor site selection: Full-thickness skin grafts are preferred because they match the color and texture of thin eyelid skin. Skin from in front of or behind the ear is the usual choice, with upper lid or inner arm skin as alternatives.
3. Graft harvest: The graft is cut with a scalpel to include the full dermis and epidermis. The surgeon then removes the fat from its underside to help it take.
4. Graft placement: The graft is sutured to the bed, dermal side down. Quilting sutures may be added to reduce dead space.
5. Donor site closure: The donor site is usually closed directly. A large donor defect may need its own repair, which matters for coding (see the next section).
6. Dressing: A bolster dressing is tied over the graft to hold it against the bed for the first five to seven days.

The operative note should cover each step, name the donor site and state the graft type. A line such as “eyelid reconstruction performed” will not get through an insurer’s clinical review.

What CCSD code C1420 includes and excludes

The donor site question causes many C1420 errors. Chapter 4 of the schedule lists no separate code for harvesting the graft, so a simple harvest and closure form part of C1420.

The bigger risk runs the other way. Several lid codes already include a graft in their descriptor. Adding C1420 on top of one of them bills the same graft twice.

Check each insurer’s current schedule before you bill, because bundling rules are set insurer by insurer.

Four questions, asked in order, settle which code carries the graft. The flow below adds the Freedom fee each code earns.

Adjacent and related CCSD codes

These chapter 4 codes sit closest to C1420. The Bupa CCSD codes guide lists the full descriptors for the ophthalmology chapter.

A temporary tarsorrhaphy is sometimes placed to protect a lower lid graft while it heals. It bills separately under its own code, C1640.

C1420 fees across UK private insurers

CCSD codes carry no national fee. Each insurer publishes its own schedule and sets what it pays for C1420.

Two published schedules give a benchmark. Freedom’s Elite schedule (January 2026) puts C1420 in its Intermediate band at £300 for the specialist and £213 for the anesthetist. National Friendly’s schedule (October 2025) pays £348.

• Bupa: Check the current C1420 rate in the Bupa code search portal for the relevant schedule year.
• AXA Health, Aviva, Vitality, WPA and Cigna: Rates sit in each insurer’s provider portal or fee schedule. Some depend on the consultant’s recognition agreement.
• Shortfalls: Where the consultant’s fee is higher than the insurer’s rate, tell the patient the expected shortfall in writing before surgery.
• Schedule version: Note the date on the schedule you quote from, because insurers revise their fees periodically.

How CCSD code C1420 maps to CPT codes

Some practices also bill international patients under US CPT coding, where a full-thickness eyelid graft usually maps to CPT 15260. The mapping below is approximate, because the two systems share no official crosswalk.

The main difference is size. CPT pays by graft area, while C1420 is a single code for the whole graft. UK insurers pay C1420 against their own CCSD schedules, never against CPT values.

Documentation requirements for CCSD code C1420

Complete documentation is the part of a C1420 claim the practice controls most. Digital intake and consent forms can build the required fields into consent, pre-op assessment and operative notes.

Every C1420 claim file should hold the following:

• Operative note: States the indication, defect size, graft type (full- or split-thickness), donor site and how it was closed.
• ICD-10 diagnosis code: UK insurers use WHO ICD-10. Common codes include C44.1 (malignant neoplasm of skin of eyelid, including canthus), H02.1 (ectropion of eyelid) and S01.1 (open wound of eyelid and periocular area). Burns of the eyelid take T26.0.
• Clinical photographs: Insurers often ask for photographs of the defect with the authorization request, and may ask again at audit.
• Histopathology report: Needed where the graft follows a tumor excision, because it confirms the indication.
• Authorization reference: The insurer’s reference number, copied onto the claim.
• Consent form: Signed consent showing the patient was told about the risks, alternatives and expected recovery.
• Fee estimate: A copy of the written fee information given to the patient, including any expected shortfall.

Check this list against your medical billing compliance routine, so notes are signed and attached before submission.

Pre-authorization for an eyelid skin graft

Most major UK private insurers expect pre-authorization before planned eyelid surgery. Requirements differ by insurer, policy and urgency, so confirm with the insurer before you list the patient.

A pre-authorization request usually needs:

• The patient’s membership or policy number
• CCSD code C1420, plus any other procedure codes planned for the same session
• The ICD-10 diagnosis code and a short clinical summary
• Photographs of the defect, and the histopathology report where a tumor was removed
• The planned surgery date and hospital

Plans sometimes change during surgery, for example when a planned C1420 becomes a C1700 reconstruction. Call the insurer and update the authorization, because a billed code that differs from the authorized one will usually be queried.

Why C1420 claims get denied

C1420 claims fail for a short list of reasons. Most of them are caught by claims management software that flags missing fields before submission.

A denial management workflow makes sure each rejection is investigated and resubmitted inside the insurer’s appeal window.

Billing C1420 with another procedure in the same session

Excision followed by a graft is the most common pairing. List each procedure with its own CCSD code, for example C1210 and C1420, and get both authorized.

Insurers set their own rules on paying a second procedure in the same session. Read the insurer’s schedule notes before you assume both fees are paid in full. If both eyelids are grafted, ask the insurer how it wants the second side shown on the claim.

Anesthetic billing alongside C1420

Eyelid grafts are done under general anesthetic or under local anesthetic with sedation. The anesthetist bills separately, so the anesthetic never goes on the surgeon’s claim.

Freedom lists a £213 anesthetist fee for C1420 in its January 2026 schedule. Make sure the anesthetist’s claim carries the authorization too, where the insurer requires it.

How Pabau carries a C1420 claim from surgery to Healthcode

Many C1420 denials start with paperwork kept outside the billing system. The authorization reference sits in an email, or the operative note reaches the insurer after the claim does.

Pabau, the practice management platform we build, keeps those pieces on one patient record. The CCSD codes, membership number, authorization reference and operative note sit together, and Pabau checks the required fields before a claim can be sent.

Pabau connects to Healthcode, so the claim builds from the patient record instead of being typed again. Insurer remittances then match against each invoice, and your team can see which graft claims are paid and which need a chase.

Conclusion

C1420 is an easy code to choose and an easy one to over-bill. The graft belongs to C1420 only when no other lid code already includes it.

Settle the code before surgery. Put every planned procedure on the authorization request, record the graft type and donor site in the note, and check the insurer’s current fee. Doing this before listing the patient protects the fee and avoids a query months later.

If the plan changes during surgery, update the authorization the same day. Book a demo to see how Pabau keeps authorization references, operative notes and CCSD claims on one patient record.
