The American Medical Association’s CPT code set defines CPT 58563 as: Hysteroscopy, surgical; with endometrial ablation (eg, endometrial resection, electrosurgical ablation, thermoablation). This code sits within the surgical hysteroscopy section and covers any energy-based method used to destroy or remove the endometrial lining via a hysteroscope.
In practical terms, the procedure involves inserting a hysteroscope into the uterine cavity under direct visualization, then applying one of several energy modalities to ablate the endometrium. Common systems billed under CPT code 58563 include NovaSure (radiofrequency energy), Her Option (cryoablation), and Minerva (plasma energy). None of these devices have device-specific CPT codes; all are reported under 58563 regardless of the technology used, per current coding guidance.
Indications and medical necessity for CPT 58563
Payer medical necessity criteria for CPT 58563 center on abnormal uterine bleeding that has not responded to conservative management. Most major payers require documented failed medical therapy (hormonal treatment or other pharmacologic options) before approving the procedure. The clinical indications most consistently accepted across Medicare and commercial plans include:
- Heavy menstrual bleeding (menorrhagia) unresponsive to medical management
- Irregular uterine bleeding with benign pathology on endometrial sampling
- Dysfunctional uterine bleeding in patients who are not candidates for or who decline hysterectomy
- Benign endometrial polyps or hyperplasia where ablation is the chosen treatment
The operative report must reflect that the patient has completed a trial of conservative therapy. A claim submitted without this documentation will typically generate a medical necessity denial regardless of the diagnosis code selection. Understanding medical billing fundamentals can help practice staff build documentation workflows that capture this information consistently before claim submission.
ICD-10 codes billed with CPT code 58563
Accurate ICD-10-CM code selection is essential for linking CPT 58563 to an accepted diagnosis. The most commonly paired codes, verified against current FY coding guidelines, appear below. Confirm these against the CDC/NCHS ICD-10-CM web tool each October when annual updates take effect.
Medicare reimbursement and fee schedule for CPT code 58563
CPT code 58563 is reimbursed differently depending on where the procedure is performed. CMS applies facility rates when the procedure is done in a hospital outpatient department (HOPD) or ambulatory surgical center (ASC), and non-facility rates when performed in a physician office setting. For most ablation procedures, the ASC or HOPD is the standard site of service. Use the Claim.MD clearinghouse integration to verify eligibility and run real-time payer checks before submitting claims for 58563, reducing the risk of place-of-service mismatches.
Payment rates are set annually under the Medicare Physician Fee Schedule (MPFS) and are subject to geographic adjustment through the Geographic Practice Cost Indices (GPCI). The figures below reflect national averages; actual payments vary by locality. Check the CMS MPFS lookup tool for your specific payment locality and current fiscal year rates. Understanding electronic remittance advice is essential for reconciling what CMS actually pays against expected amounts, particularly given geographic adjustments.
RVU breakdown for CPT 58563
Relative Value Units determine Medicare payment. The three RVU components for CPT code 58563 combine into a total that is multiplied by the annual conversion factor. The FastRVU 2026 lookup tool provides current work, practice expense, and malpractice RVU values by locality.
Important: RVU values are updated annually. Verify current figures against the CMS MPFS files or the FastRVU tool before using them for revenue projections. The basic principles of revenue cycle management apply directly to how RVU-based payments flow through a practice’s billing system.
Facility vs non-facility payment rates
Endometrial ablation is most often performed in an ASC or HOPD, meaning the facility rate applies to the physician’s claim. The facility absorbs the supply and equipment costs and bills CMS separately under the ASC payment system. Billing CPT code 58563 with Place of Service 11 (office) when the procedure was actually performed at an ASC triggers a claim mismatch and will result in denial or overpayment recovery.
Pro Tip
Verify the place of service code on every 58563 claim before submission. POS 22 (on-campus HOPD), POS 23 (emergency), and POS 24 (ASC) each carry distinct rate implications. A mismatch between where the procedure was performed and the POS code on the claim is one of the most common and most preventable denial triggers for endometrial ablation billing.
Global period for CPT code 58563
CPT code 58563 carries a 90-day global surgical period. This means all routine post-operative care provided by the operating physician within 90 days of the procedure is included in the surgical payment and cannot be billed separately. The global period begins the day after the procedure.
Services that remain separately billable during the global period include:
- Visits for conditions unrelated to the ablation (bill with modifier -24 and appropriate diagnosis code)
- Treatment of complications requiring a return to the operating room (bill with modifier -78)
- Staged procedures or additional unrelated surgical services (modifier -79)
- Evaluation and management services provided by a different physician in the same group
Solid revenue cycle management practices require flagging all encounters for patients within 90 days of a 58563 procedure to confirm whether the visit is global-included or separately billable before submitting a claim.
Modifiers for CPT code 58563
Appending the correct modifier is critical when additional circumstances affect how CPT code 58563 is billed. The table below covers the modifiers most frequently applied in OB/GYN coding.
Documentation requirements for billing CPT 58563
Every operative note for CPT code 58563 must support both the procedure performed and the medical necessity for performing it. A thin operative report is the single most common reason clean claims become denials during post-payment audit. Understanding superbill components and how the operative report feeds into them helps practices build documentation-to-billing workflows that hold up under payer review.
The operative note should document all of the following elements:
- Approach: confirm the procedure was performed hysteroscopically (not laparoscopically or via open approach)
- Energy modality: specify the ablation technology used (electrosurgical, thermal balloon, radiofrequency, cryoablation, or laser)
- Device used: document the device name and model (NovaSure, Her Option, Minerva, etc.)
- Uterine cavity findings: describe the endometrial lining appearance, any polyps, fibroids, or adhesions observed
- Ablation extent: confirm ablation was completed as intended or note any limitations
- Failed conservative treatment history: reference prior medical therapy trials (hormonal agents, progestins, NSAIDs) that did not produce adequate results
- Indication: the specific clinical reason for the procedure, linked to the ICD-10 code on the claim
Pabau’s claims management software allows OB/GYN practices to attach operative reports directly to procedure records, reducing the turnaround time for documentation requests during payer audits.

Related CPT codes: 58558, 58561, 58555, and 58552
CPT code 58563 is one of several hysteroscopy codes that OB/GYN billers must distinguish carefully. Selecting the wrong code in this family is a common unbundling risk. The AAPC Codify CPT lookup provides official descriptors for each code side by side.
CPT 58563 vs CPT 58558: Key differences
The most common coding error in this family is billing CPT 58558 (polypectomy/biopsy) and CPT code 58563 (endometrial ablation) together for the same hysteroscopic session without a modifier. CMS NCCI edits bundle these two codes because diagnostic hysteroscopy is considered a component of surgical hysteroscopy.
Billing both without modifier -59 or an X-modifier will generate an automatic edit. Modifier -59 may be appended only when the biopsy or polypectomy was performed as a distinctly separate service with its own documentation supporting a different indication.
Bundling rules and unbundling risks for CPT 58563
CMS National Correct Coding Initiative (NCCI) edits apply to CPT code 58563 and restrict which codes can be billed together in the same session. The key bundling relationships to know:
- 58555 bundles into 58563: Diagnostic hysteroscopy is a component of surgical hysteroscopy; cannot be billed separately without modifier -59 and documented distinct indication
- 58558 bundles into 58563: Polypectomy/biopsy bundles when performed as part of the same hysteroscopic session
- Anesthesia codes: General anesthesia is not separately reportable by the operating physician; the anesthesiologist bills independently
Understanding clean claim requirements for bundled procedures helps billing staff decide when modifier use is appropriate versus when it creates audit exposure. NCCI edits are updated quarterly, so verify the current edit table before applying any modifier intended to unbundle 58563 from companion codes.
The documentation standards applied across CPT code families follow the same principle: Each separately billed service needs its own documented clinical rationale.
Common billing errors and how to avoid them with CPT 58563
The billing errors that most consistently delay or deny payment for CPT code 58563 are predictable. Most are addressable with a pre-submission checklist. Proactive denial management workflows catch these before claims leave the practice.
Practices that adopt medical billing compliance protocols for high-denial CPT codes see significantly fewer post-payment recoupments. A structured approach to medical billing across the entire OB/GYN code family is more effective than addressing individual denials after the fact.
Payer-specific coverage policies for CPT 58563
Coverage criteria for endometrial ablation under CPT code 58563 vary meaningfully across commercial payers. Prior authorization is required by most major commercial plans; requirements vary by payer and plan, so verify current policy before scheduling. Key payer considerations include:
- Medicare: covers endometrial ablation when medical necessity is documented; no blanket age restriction but clinical indications must be established
- Aetna and Anthem/BCBS: typically require documentation of failed medical management (minimum 3-6 months of hormonal therapy) and a normal endometrial biopsy before approving ablation
- UHC and Cigna: payer policies not directly verified for all plan types; treat as requiring prior authorization and confirm with the specific plan before scheduling
- Age and parity restrictions: some payers restrict coverage to patients who are premenopausal and have completed childbearing; confirm the specific plan’s criteria
The American College of Obstetricians and Gynecologists (ACOG) publishes clinical practice guidelines for endometrial ablation that can support prior authorization appeals when a payer denies on medical necessity grounds.
Pro Tip
Build a payer-specific prior authorization tracker within your practice management system. For CPT code 58563, document the PA number, authorization date, authorized date of service range, and approved ICD-10 codes for every case. When a claim denies for authorization reasons after the procedure, a documented PA trail is the fastest path to resolution.
Conclusion
CPT code 58563 is one of the higher-value OB/GYN surgical codes, and its denial rate reflects how often documentation and place-of-service details are missed rather than miscoded. The procedure itself is straightforward to code; the complexity is in proving medical necessity, selecting the right ICD-10 pair, and managing the 90-day global period correctly.

Frequently Asked Questions
What is CPT code 58563?
CPT code 58563 is a surgical hysteroscopy code describing endometrial ablation, which covers all energy-based methods of destroying the uterine lining including electrosurgical, thermal balloon, radiofrequency, cryoablation, and laser techniques. It is used regardless of which specific device (NovaSure, Her Option, Minerva) performs the ablation.
What is the difference between CPT 58563 and 58558?
CPT 58558 covers hysteroscopic biopsy, polypectomy, or D&C without an ablation component, while CPT code 58563 covers endometrial ablation specifically. NCCI edits bundle 58558 into 58563 when both are performed in the same session; modifier -59 may override only when a distinctly separate, documented service exists.
What ICD-10 codes are used with CPT 58563?
The most common ICD-10-CM codes paired with CPT 58563 are N92.0 (excessive and frequent menstruation with regular cycle) and N92.1 (excessive and frequent menstruation with irregular cycle). N92.4, N85.00, and N84.0 are also used depending on the specific clinical presentation. Verify all codes against the current fiscal year ICD-10-CM release each October.
What is the global period for CPT code 58563?
CPT code 58563 has a 90-day global period beginning the day after the procedure. Routine post-operative care during this window is included in the surgical payment. Visits for unrelated conditions (modifier -24), return to OR for complications (modifier -78), and staged unrelated procedures (modifier -79) can be billed separately with appropriate documentation.
Is endometrial ablation covered by Medicare?
Yes, Medicare covers endometrial ablation under CPT code 58563 when medical necessity is properly documented, including evidence that conservative management was attempted without adequate results. There is no blanket age restriction, but the operative note must support the clinical indication and the ICD-10 code must link to an accepted diagnosis.
Can CPT 58563 and 58558 be billed together?
Generally no, not without modifier -59 and documentation of a distinct service. NCCI edits bundle CPT 58558 into CPT code 58563 when both are reported for the same hysteroscopic session. Bilateral billing without a modifier will be denied; modifier use without a separately documented indication creates audit risk.
