CCSD code M1110 – Diagnostic endoscopic kidney examination

Key takeaways

CCSD code M1110 covers a diagnostic endoscopic examination of the kidney, and a biopsy taken during that look is part of the code.

If the surgeon treats a stone or a cyst in the same procedure, the therapeutic code replaces M1110 on the claim.

CCSD lists six unacceptable combinations for M1110, including diagnostic ureterorenoscopy (M1120) and endoscopic examination of the ureter (M3000).

Confirm pre-authorization before the procedure date, and tell the insurer if the code changes from the one it authorized.

Pabau’s claims management software keeps the operative note, the pre-auth reference and the Healthcode submission on one patient record.

CCSD code M1110 is a diagnostic look inside the kidney

CCSD code M1110 is the procedure code UK private insurers use for a diagnostic endoscopic examination of the kidney, including biopsy. The urologist passes an endoscope into the kidney, inspects it and, where needed, takes a tissue sample. No treatment is billed under this code.

The code sits in Chapter 12 of the Clinical Coding and Schedule Development (CCSD) schedule, which covers the urinary system and male reproductive organs. Within that chapter it belongs to sub-chapter 12.1.0, Kidney/Renal Pelvic.

Billing M1110 well comes down to one question, asked of every operative note. Did the surgeon only look, or did they treat something? The answer decides whether M1110 stays on the claim or gives way to another code.

Our index of CCSD codes lists the neighboring kidney, ureter and bladder procedures.

M1110 has close neighbors in the Chapter 12 kidney codes

M1110 errors usually start with a code that describes the same organ with a different purpose or route. The table sets the codes most often confused with it side by side, using each code’s CCSD narrative.

The therapeutic side of the same line is covered in our guide to CCSD code M1000.

M1110 or M1120? Let the operative note decide

OPCS-4, the classification the NHS uses, files diagnostic endoscopy of the kidney under category M11. The same category holds retrograde endoscopic examination of the kidney NEC (M11.3), which is where an NHS ureterorenoscopy usually lands.

CCSD splits the two. Diagnostic ureterorenoscopy has its own code, M1120, and it appears on the M1110 unacceptable-combination list. A coder translating from an NHS OPCS code can therefore land on M1110 when the note describes a ureterorenoscopy.

The M1110 narrative does not name an access route, so code from what the note describes. Three quick questions settle most cases:

• Was anything treated? If yes, M1110 drops out and the therapeutic code takes the line.
• Does the note describe a ureterorenoscopy? Then weigh M1120 against M1110, and bill only one of them.
• Did the look stay below the kidney? M3000 covers the ureter, and M4510 covers a flexible cystoscopy of the bladder alone.

When the note leaves the route unclear, ask the surgeon before you code. A one-line addendum costs far less than a rejected claim.

Add the open-biopsy check to those three questions and you have a short decision flow to run against every note.

Here is how an M1110 claim moves from booking to payment

A clean M1110 claim passes through six stages. When one comes back rejected, the cause is usually a check skipped at one of them.

1. Booking. The practice requests pre-authorization with the planned CCSD code, the diagnosis, and the consultant and hospital details.
2. Procedure day. The surgeon completes the operative note, stating the side, the findings and whether a biopsy was taken.
3. Coding. The coder reads the note against the neighboring codes and confirms that no therapeutic step took place.
4. Authorization check. If the final code differs from the authorized one, the practice tells the insurer before invoicing.
5. Submission. The invoice carries M1110, the ICD-10 diagnosis, the pre-auth reference and the membership number, then goes through Healthcode or the insurer’s portal.
6. Remittance. The insurer pays, queries or rejects the claim. A query often asks for the operative note, so keep it to hand.

Pre-authorization for M1110 belongs before the procedure date

Most UK private medical insurers expect members to authorize a urology procedure before it happens. Rules differ by plan and change between policy years, so treat the table as a starting point and confirm with each insurer.

A diagnostic kidney endoscopy is usually booked because earlier tests left a question open, such as an unexplained finding on imaging. Put that reason on the request, because it is the clinical case for the look.

Our guide to Bupa CCSD codes walks through Bupa’s authorization steps in more detail.

The operative note has to carry the M1110 claim

Insurers audit M1110 against the operative note, so the note must show a diagnostic examination and nothing more. Record each of these items:

• Approach and instrument: How the kidney was reached and which endoscope was used.
• Side: Left, right or both, matching the side on the invoice.
• Findings: What the surgeon saw, in enough detail to justify the look.
• Biopsy: Whether a sample was taken, from where, and that it went to histology.
• No treatment: A plain statement that no stone, cyst or lesion was treated.
• Anesthesia and complications: The anesthetic used and any problem during the procedure, even a minor one.
• Indication: The reason for the examination, which should match the ICD-10 diagnosis on the claim.

A templated note with a field for each item beats free dictation. The surgeon cannot skip a field the form asks for.

Six codes CCSD won’t accept alongside M1110

CCSD publishes an unacceptable-combination list for M1110. None of the codes below should sit on the same claim as M1110 for one procedure.

CCSD calls its coding principles non-exhaustive guidelines. Each insurer decides whether to adopt a given combination, so a pair missing from this list is not automatically payable.

Why M1110 claims come back rejected

Rejections on M1110 repeat the same few patterns, and each one is preventable at the desk. For claims that still return, our guide to denial management in healthcare covers tracking and appeals.

A typical case shows how this plays out. A patient is booked for a diagnostic endoscopy under M1110 after an unclear scan. During the procedure, the surgeon finds a small kidney stone and fragments it.

The episode now belongs under M0910, which CCSD bars alongside M1110. The practice calls the insurer, has the authorization moved to M0910, and bills that code alone. Billing both codes, or keeping M1110 after the stone work, would have drawn a rejection.

Common M1110 coding mistakes start before the claim

Coding errors on M1110 tend to be judgment calls made too early or too quickly. Four of them come up again and again:

• Coding from the operating list. The list shows what was planned. The note shows what was done, and only the note counts.
• Translating straight from OPCS-4. An NHS ureterorenoscopy coded to M11.3 does not map neatly to M1110, because CCSD gives diagnostic ureterorenoscopy its own code, M1120.
• Adding a biopsy line. The narrative already includes the biopsy, so a separate biopsy code is unbundling.
• Assuming an unlisted pair is fine. Insurers can apply bundling rules of their own beyond the CCSD list.

Run this checklist before you submit M1110

Before the claim leaves the practice, tick each line. If one fails, fix it first.

• The note describes an examination and no treatment.
• The side is on both the note and the invoice.
• No code from the unacceptable-combination list sits on the same claim.
• There is no separate biopsy line.
• The pre-auth reference is current and names M1110.
• The ICD-10 diagnosis matches the indication in the note.
• The membership number and insurer details match the policy.

How Pabau keeps M1110 claims clean from note to Healthcode

In many urology practices, the operative note, the pre-auth reference and the invoice sit in separate places. The coder then rebuilds the episode at billing time, which is where wrong codes and missing references creep in.

Pabau, the practice management platform we build, keeps all three on the same patient record. Its claims management software checks that required fields, such as the membership number and authorization code, are filled in before sending.

Claims then go through Healthcode to insurers such as Bupa, AXA Health and Vitality. The submission stays on the patient’s record, so the note is one click away when an insurer queries the claim.

Send clean CCSD claims for urology

Pabau keeps the operative note, the pre-auth reference and the CCSD code on one record, then sends the claim through Healthcode to UK insurers.

Conclusion

M1110 is one of the simpler kidney codes to get right. The claim just has to reflect what happened during the procedure, not what was booked.

The habit worth building is a second read of the note before the code goes on the invoice. If something was treated, the code changes and so does the authorization. That check takes a minute and saves a resubmission weeks later.
