CCSD code H0900 – Left hemicolon excision

Key takeaways

CCSD code H0900 covers excision of the left hemicolon in UK private healthcare, under CCSD reference Fk.065.

The approach picks the code: H0900 for the open operation, H1880 for laparoscopic assistance and H1882 for robotic assistance.

No H09 series exists, because H0900 is the only H09xx code. Right-sided and total colon resections take H0700, H0610 or H0510.

UK private medical insurers such as Bupa and AXA Health expect pre-authorization, and the authorization number belongs on the invoice.

Pair H0900 with an ICD-10 diagnosis that matches the segment removed, such as C18.6 for a descending colon tumor.

What is CCSD code H0900?

CCSD code H0900 is the UK private healthcare code for excision of the left hemicolon, an operation surgeons usually call a left hemicolectomy. It sits in section 11.5.0 Large Intestine, within chapter 11.0.0 Abdomen (Excl. Urinary & Reproductive Organs) of the CCSD Schedule. Its CCSD reference is Fk.065.

CCSD stands for Clinical Coding and Schedule Development. The CCSD Group maintains the codes UK private consultants quote on their invoices. Private medical insurers such as Bupa, AXA Health, Aviva, Vitality and WPA use them to identify the procedure they are paying for.

The official descriptor is “Excision of left hemicolon.” Quote that wording on invoices and insurer correspondence. You can confirm any code and its descriptor on the CCSD website.

The CCSD Group does not set fees or decide reimbursement. Each insurer applies its own fee schedule and benefit rules to H0900. For Bupa patients, check how Bupa uses CCSD codes before you quote a fee.

The procedure: What excision of the left hemicolon involves

A left hemicolectomy removes the descending colon, the part of the large intestine supplied by the inferior mesenteric artery. How much of the neighboring bowel comes out depends on the diagnosis and the margins the surgeon needs.

• Descending colon: The core of every left hemicolectomy.
• Splenic flexure: Mobilized, and often removed, when the disease sits at or near the flexure.
• Left transverse colon: Included when a cancer operation needs a wider margin on the proximal side.
• Proximal sigmoid colon: Included when the distal margin extends past the descending colon.

In an open operation, the surgeon works through an abdominal incision. The left colon is mobilized and the inferior mesenteric vessels, or their branches, are divided. The segment is removed, and the bowel ends are joined with an anastomosis or brought out as a stoma.

Code from what the operation note says came out, not from the name on the operating schedule. If the note describes a different segment or extent, one of the related codes below fits better.

Open, laparoscopic or robotic: Choosing between H0900, H1880 and H1882

The CCSD Schedule separates left colon resection by surgical approach. It does this with separate codes, not with an approach modifier added to H0900.

So a laparoscopic left hemicolectomy is billed as CCSD code H1880, not as H0900 with a modifier. Read the approach from the operation note, never from the booking.

Some laparoscopic operations are converted to open surgery. CCSD’s coding principles and the insurer’s rules decide which code applies after a conversion. Check both before you submit, and record the conversion and its reason in the operation note.

Related CCSD codes: How H0900 fits in the CCSD Schedule

There is no “H09 series” of colectomy codes. H0900 is the only code in the H09xx range, so the neighboring codes below describe other segments, extents or approaches.

Each descriptor above is quoted from the CCSD Schedule. If the note shows only the sigmoid colon came out, H1000 is the code to check. For a right-sided operation, start with H0700. The grid below sorts the left and right codes by segment and approach.

ICD-10 diagnoses commonly paired with H0900

H0900 fits disease in the left colon. Insurers ask for the diagnosis at pre-authorization, and the ICD-10 code should match the segment removed.

The WHO ICD-10 browser gives the official description for each code. For cancer cases, include the staging in the pre-authorization request. A diagnosis that points elsewhere in the colon, such as C18.3 for the hepatic flexure, does not support H0900.

Documentation requirements for an H0900 claim

Insurers can ask for clinical records before they pay a surgical claim. Keep this set on file for every H0900 operation:

• Operation note: It names the procedure, states the open approach, and records the segment removed and the resection margins.
• Reconstruction: The note says whether an anastomosis was formed or a stoma was brought out, and which type.
• Authorization number: Record the insurer’s authorization number before you raise the invoice.
• Signed consent: The consent form names the same procedure and approach as the operation note.
• Histopathology request: It shows the specimen went for analysis, which supports a cancer or polyp diagnosis.
• ICD-10 diagnosis: It matches the disease confirmed by imaging, colonoscopy or histology.

A missing operation note or authorization number causes avoidable delays. A short checklist for each code, part of everyday medical billing compliance, confirms both are on file before the claim goes out.

Pre-authorization: What UK private medical insurers expect

Patients with private medical insurance normally need their insurer’s authorization before planned treatment. A left hemicolectomy is major surgery, so contact the insurer well before the operation date.

Insurers set their own rules, and those rules change. Confirm the current process with the patient’s insurer. A typical request includes:

1. The CCSD code and diagnosis: H0900 with the ICD-10 code that explains why the operation is needed.
2. Supporting investigations: The colonoscopy report, imaging findings, and multidisciplinary team notes for a cancer case.
3. Consultant and hospital details: The surgeon, the anesthetist and the hospital where the operation will take place.
4. The planned admission: The date and the expected length of stay.

The insurer confirms what the policy covers and issues an authorization number. If the approach changes after authorization, tell the insurer, because the code changes with it.

Billing H0900: Surgeon, anesthetist, hospital and added procedures

H0900 describes the surgeon’s procedure. The anesthetist and the hospital invoice for their own part of the same admission, quoting the same date and authorization number.

Steps that are part of the resection, such as mobilizing the colon and closing the wound, belong inside H0900. Adding a code for an incidental step invites an unbundling query.

A separate procedure is different, such as a stoma formed when no anastomosis is made. The CCSD entry for H0900 links to coding principles that set out which combinations are allowed. Check them, and the insurer’s rules, before you put a second code on the claim.

Common reasons H0900 claims are rejected

H0900 rejections follow a predictable pattern, and most can be prevented before submission. Effective denial management in healthcare starts with knowing why claims fail.

How to challenge a rejected claim

Start with the cause on the rejection notice. An administrative error, such as a missing authorization number, usually needs a corrected claim rather than a complaint.

1. Correct and resubmit: Fix the code, diagnosis or missing detail, then resubmit with the operation note attached.
2. Query the decision with the insurer: For a clinical or coverage decision, send the operation note, the authorization reference and a letter from the surgeon.
3. Use the insurer’s complaints process: If the query fails, the patient can make a formal complaint as the policyholder. UK insurers generally have eight weeks to send a final response.
4. Refer to the Financial Ombudsman Service: If the patient disagrees with the final response, or none arrives in eight weeks, they can refer the complaint. They usually have six months from the final response to do so.

The Financial Ombudsman Service is free for consumers. Each insurer publishes its own complaints process, so follow the steps on its website.

How Pabau supports H0900 claims

Paperwork for a colon resection often ends up in several places. The operation note sits in one system, the consent form in another, and the invoice in a third. Each hand-off risks a wrong approach code or a lost authorization number.

Pabau keeps those documents on one patient record. Patients sign consent and medical history forms online, and the signed copies land on the same file. Pabau Scribe, our AI scribe, drafts clinical notes, so the record of each consultation is ready sooner.

Your team still chooses the code. Invoicing runs through Pabau’s claims software for consultants, from the same patient record. The authorization number and the operation note then sit next to the invoice when you check it.

Keep every H0900 claim document in one place

Pabau keeps the operation note, signed consent and invoice on one patient record, so your team can check each claim before it goes out.

Conclusion

Code H0900 only when the left hemicolon was removed through an open incision. A laparoscopic operation goes on H1880 and a robotic-assisted one on H1882, so the operation note decides the code.

Before you submit, confirm three facts. The note states the approach, the authorization number is on the invoice, and the ICD-10 code matches the left colon. A short check costs less than a rejection and a resubmission.
