CCSD code Q1700 – Therapeutic endoscopic uterus operations

Key takeaways

CCSD code Q1700 covers hysteroscopic endometrial ablation, such as rollerball, loop resection and thermal fluid systems, with or without Mirena coil insertion.

Microwave and radiofrequency ablation are excluded from Q1700 and have their own CCSD codes.

The most common denial cause is coding a microwave or NovaSure procedure under Q1700, so confirm the operative technique before code selection.

Bupa, AXA Health, Aviva and Vitality all require pre-authorisation before endometrial ablation, and proceeding without it typically results in non-payment.

Pabau’s digital forms and claims tools help gynaecology practices capture the operative detail and authorisation codes that payers check on Q1700 claims.

CCSD code Q1700: Definition and clinical scope

CCSD code Q1700 is the Clinical Coding and Schedule Development code for therapeutic hysteroscopic operations on the uterus. Its official descriptor includes endometrial ablation, excludes microwave or radiofrequency ablation, and allows Mirena coil insertion in the same procedure. The CCSD schedule files it under Chapter 14, Uterus/Adnexa.

The code applies when the endometrium is destroyed with energy delivered through the hysteroscope, using any modality other than the two exclusions.

The “therapeutic endoscopic” descriptor distinguishes Q1700 from diagnostic hysteroscopy codes. A purely diagnostic hysteroscopy, with no operative intervention, falls under a different CCSD code. Q1700 applies only when a therapeutic procedure is carried out through the hysteroscope.

The procedure: What therapeutic endoscopic operations on the uterus involve

Therapeutic endoscopic operations on the uterus are hysteroscopic surgical procedures performed to treat abnormal uterine bleeding, most commonly menorrhagia. The procedure is typically performed as a day case under general or regional anaesthesia, with the hysteroscope introduced transcervically to access the uterine cavity.

Techniques within Q1700’s scope include:

• Rollerball ablation: An electrosurgical rollerball electrode destroys the endometrial lining by rolling it across the uterine surface under direct hysteroscopic vision.
• Loop resection (TCRE): Transcervical resection of the endometrium shaves away the endometrial layer with a wire loop electrode. It is often combined with rollerball for the cornua.
• Thermal balloon ablation: A fluid-filled balloon is heated inside the uterus to destroy the endometrium. It is eligible under Q1700 provided the system is not microwave- or radiofrequency-based.
• Other hysteroscopic thermal systems: Systems such as hydrothermal ablation fall within scope, provided they are not microwave- or radiofrequency-based.

The typical patient has abnormal uterine bleeding (ICD-10 N92.x or N93.x), has completed childbearing, and has not responded to medical management. NICE guidance NG88 sets out the clinical pathway, with hysterectomy as a further surgical option. That operation has its own CCSD codes, such as Q0880. The Royal College of Obstetricians and Gynaecologists (RCOG) and the British Society for Gynaecological Endoscopy (BSGE) provide clinical standards for the procedure.

What Q1700 includes and what it excludes

The exclusion clause in the Q1700 descriptor is explicit. Microwave endometrial ablation and radiofrequency endometrial ablation are both carved out and require separate CCSD codes. Using CCSD code Q1700 for either of these techniques is a miscoding that payers will challenge.

When selecting a code from the operative note, the coder must identify the energy modality by name, as the diagram below shows. If the note says “NovaSure” or “Microsulis MEA system,” Q1700 does not apply. If the note describes hysteroscopic rollerball, loop resection, or thermal fluid delivery without naming a microwave or RF device, Q1700 is the correct code.

Related and neighbouring CCSD codes

Several CCSD codes sit adjacent to Q1700 in the gynaecological endoscopy family. Knowing their boundaries prevents miscoding and supports accurate claim building. Billing guides for neighbouring procedures sit in the CCSD code library.

OPCS-4 and NHS equivalent codes

OPCS-4 is the NHS procedure classification used for NHS episodes and NHS reference costs. Practitioners working across NHS and private settings often need to cross-reference CCSD Q1700 to OPCS-4. Hysteroscopic therapeutic procedures sit in OPCS-4 category Q17, therapeutic endoscopic operations on uterus, and the subcode depends on the technique. Practices that also bill US payers report hysteroscopic endometrial ablation as CPT 58563.

OPCS-4 and CCSD do not map 1:1. The NHS Classifications Browser at classbrowser.nhs.uk provides authoritative OPCS-4 lookup. Treat any cross-reference as guidance only, and verify the subcode against the current OPCS-4 release for NHS coding purposes.

Diagnosis codes to pair with Q1700

A complete private healthcare claim requires both the CCSD procedure code and the appropriate ICD-10 diagnosis code. Missing or mismatched diagnosis codes are a leading cause of claim rejection. The ICD-10 codes most commonly submitted alongside Q1700 are:

The principal diagnosis code should reflect the clinical reason the procedure was performed, not the procedure itself. If more than one diagnosis applies, list the primary indication first. Confirm coding with the consultant’s clinical letter and discharge summary before submission.

Documentation requirements for a valid Q1700 claim

Payer adjudicators reviewing a Q1700 claim look for evidence in the operative note on two points. The procedure was performed hysteroscopically, and neither excluded modality was used. Vague documentation is the second most common trigger for claim queries after miscoding. Using digital operative note templates that prompt for each required field reduces the risk of incomplete records.

A valid operative note for a Q1700 claim should include:

• Instrument confirmation: Name the hysteroscope and energy source used (e.g. “Karl Storz 10mm operative hysteroscope with rollerball electrode”).
• Technique description: State the ablation method explicitly (rollerball, loop resection, thermal fluid system name).
• Exclusion confirmation: Confirm the system used was not microwave- or radiofrequency-based, particularly where the technique could be ambiguous.
• Indication: Document the clinical indication (menorrhagia, AUB) and that conservative management had been tried.
• Anaesthetic details: Type of anaesthesia (general, regional, local), administered by whom.
• Setting: Day case or inpatient, with the facility name and date.
• Post-operative findings: Any incidental findings at hysteroscopy (polyps, fibroids) and whether a concurrent procedure was performed.

If a concurrent procedure such as polypectomy was performed, document it as a distinct surgical step. Folding it into the ablation description undermines separate billing where the payer permits it. An endometrial biopsy taken at the same sitting has its own code, Q2020, and the same payer bundling check applies.

Pre-authorisation requirements for endometrial ablation

All major UK private health insurers require pre-authorisation before elective endometrial ablation. Proceeding without authorisation typically results in the claim being declined regardless of the coding accuracy. Payer rules change, so verify current policy on the insurer’s provider portal before the procedure date. For detailed guidance on submitting claims to Bupa, see Bupa’s CCSD billing requirements.

When authorisation is granted, retain the authorisation reference number. This number must appear on the claim invoice. If the procedure date changes, check whether the authorisation requires updating.

Bundling rules: Billing CCSD code Q1700 alongside other codes

Bundling rules determine which CCSD codes can be billed concurrently with Q1700 on the same claim. Errors here cause two problems. Overbilling adds concurrent codes that Q1700 already includes, and underbilling misses a legitimately separate procedure.

Bundling rules are insurer-specific and may differ between Bupa, AXA Health, Aviva, and Vitality. Where the clinical record supports a concurrent procedure, add a brief explanation note to the claim. Reference the operative note section that documents the distinct surgical step.

Common CCSD Q1700 claim denial reasons and how to prevent them

Understanding why Q1700 claims are rejected lets billing teams act before submission rather than after. The most frequent denial triggers and their preventive actions are listed below.

Claims software such as Pabau, the practice management platform we build, validates each claim before it leaves the practice. That check catches missing or invalid details, such as an absent authorisation code, before the insurer sees them.

How to submit a Q1700 claim: Step-by-step

Most CCSD reference pages list code definitions but not the submission workflow. This step-by-step covers the path from operative list to paid invoice. Pabau’s claims management software sends the claim through Healthcode and tracks it from pending to paid.

1. Confirm the technique from the operative note. Identify the energy modality by name. If the note says “rollerball” or “loop resection,” Q1700 applies. If it says “NovaSure,” “Microsulis,” or “microwave,” use the specific code for that modality.
2. Obtain pre-authorisation. Submit the pre-auth request to the relevant insurer before the procedure date, citing the planned CCSD code Q1700, the ICD-10 indication, and the consultant’s details. Retain the authorisation reference number.
3. Build the claim with the correct code pair. Enter CCSD code Q1700 as the primary procedure code. Add the ICD-10 diagnosis code (most commonly N92.0 for menorrhagia). Add any legitimately separate concurrent procedure codes only after verifying bundling rules with the payer.
4. Include the authorisation reference on the invoice. Every claim invoice must carry the insurer’s authorisation number. Missing it is an instant rejection at most payer portals.
5. Attach or reference the operative note. Some insurers require the operative note to accompany the claim; others request it only on query. Confirm the payer’s submission format via their provider portal.
6. Submit and track. Submit electronically via the insurer’s provider portal or approved claims pathway. Check the insurer’s stated acknowledgement time on its portal and set a follow-up reminder.
7. Respond to queries promptly. If the payer requests additional information (typically the operative note or clarification of technique), respond within the query window stated in the payer’s terms. Late responses result in the claim lapsing.

How Pabau keeps Q1700 claims documented and authorised

Gynaecology practices billing under CCSD face the same tension as any specialty. The consultant spends the day in theatre, away from a billing workstation. Practice managers need the right detail captured during the patient journey, without phoning the consultant each time a payer queries a claim.

Pabau keeps the clinical record and the billing record on one patient file. Treatment note templates prompt for the hysteroscope, energy source and technique, so the operative note carries the evidence a coder needs for Q1700.

Each insurer’s pre-authorisation is stored as a case, and its authorisation code follows the appointment through to the claim. Claim validation flags missing details before the claim goes to Healthcode, and a rejected claim comes back with its reason attached.

Manage CCSD billing workflows without the paperwork headaches

Pabau helps gynaecology practices and private healthcare teams document procedures correctly, track pre-authorisation status, and submit accurate claims, all from one place.

Conclusion

Q1700 claims rarely fail on the code itself. They fail when the operative note never names the energy source, or when the claim reaches the insurer without its authorisation reference.

Fix both at the source. Build the modality into the operative note template, and log the authorisation before the theatre date. A coder can then choose between Q1700 and the MEA or RFA codes quickly, and defend the choice if the insurer queries it.
