TL;DR: The Centers for Medicare & Medicaid Services modified NCD 163 covering the Gravlee Jet Washer, effective March 7, 2026. The core rule hasn't changed, but the policy update confirms what gets paid and what doesn't — and the asymptomatic exclusion is where most claims go wrong.
CMS Gravlee Jet Washer coverage policy under NCD 163 in the Medicare system draws a hard line: this device is covered only when a patient shows clinical symptoms of endometrial disease. No symptoms, no reimbursement. This policy does not list specific CPT or HCPCS codes, so your billing team needs to pay close attention to the diagnostic and procedure codes your practice currently uses for this service.

CMS Gravlee Jet Washer Coverage Criteria and Medical Necessity Requirements 2026
NCD 163 is the National Coverage Determination governing Medicare coverage of the Gravlee Jet Washer — a sterile, disposable diagnostic device used to detect endometrial cancer. The Centers for Medicare & Medicaid Services classifies this under the Diagnostic Tests benefit category.
The medical necessity standard here is narrow and specific. CMS covers the device and its related diagnostic services only when the patient shows clinical symptoms or signs suggestive of endometrial disease. The policy cites irregular or heavy vaginal bleeding as the primary clinical indicator.
That's a tight standard. Your documentation needs to reflect active, present symptoms — not a history of symptoms that resolved, and not a clinician's concern about future risk.
There are no prior authorization requirements listed in NCD 163 for this device. That said, the absence of a prior auth requirement doesn't make this a low-risk claim. The symptom documentation requirement is the gatekeeper here, and a missing or vague clinical note is as damaging as a missing prior authorization.
The real issue with CMS Gravlee Jet Washer coverage policy is the word "indicated." CMS uses it deliberately: the device is indicated where a patient exhibits symptoms. If your documentation doesn't establish that clinical indication clearly, the claim is exposed — regardless of what procedure was performed.
CMS Gravlee Jet Washer Exclusions and Non-Covered Indications
This is where billing teams lose money. The exclusion is clean and absolute: CMS will not pay for the Gravlee Jet Washer — or any related diagnostic services — when the exam is performed on an asymptomatic patient.
CMS cites §1862(a)(7) of the Social Security Act directly. That's the statutory provision that bars Medicare payment for routine physical checkups. If the Gravlee Jet Washer is used as a screening tool during a wellness visit or annual exam, CMS treats it as a routine checkup service. Full stop.
The claim denial risk here is high. If a gynecologist uses this device during a preventive visit — even with good clinical intentions — and the documentation doesn't show a symptomatic indication, CMS won't pay. Your billing team will see the denial, but by then the service is already rendered and the window for correction is narrow.
Cross-check your encounter documentation before billing. The physician's note needs to establish the symptom — not just list the procedure. "Patient presented with irregular vaginal bleeding" is useful. "Annual gynecologic exam" is not.
This is also worth flagging in your compliance workflow. If your practice uses the Gravlee Jet Washer with any regularity, audit a sample of recent claims. Check whether the documentation consistently shows symptomatic presentation. If it doesn't, loop in your compliance officer before March 7, 2026.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Patient with irregular or heavy vaginal bleeding (symptomatic for endometrial disease) | Covered | Not specified in NCD 163 | Documentation must establish active symptoms |
| Related diagnostic services performed alongside the device (symptomatic patient) | Covered | Not specified in NCD 163 | Services must be tied to symptomatic indication |
| Use of device on asymptomatic patient | Not Covered | Not specified in NCD 163 | Excluded under §1862(a)(7) — routine checkup prohibition |
| Related diagnostic services for asymptomatic patient | Not Covered | Not specified in NCD 163 | Exclusion applies to both device and associated services |
| Routine screening or preventive exam use | Not Covered | Not specified in NCD 163 | Treated as routine physical checkup under Medicare statute |
CMS Gravlee Jet Washer Billing Guidelines and Action Items 2026
Gravlee Jet Washer billing under NCD 163 is not complicated — but it's unforgiving. The asymptomatic exclusion creates a clean bright line, and CMS doesn't give you a middle ground. Here's what your team needs to do before the effective date of March 7, 2026.
| # | Action Item |
|---|---|
| 1 | Audit your documentation templates for gynecologic diagnostic procedures. Make sure your templates prompt physicians to record the specific symptom driving the use of this device. "Irregular vaginal bleeding" or "heavy vaginal bleeding" needs to appear in the clinical note — not just the procedure order. |
| 2 | Flag any encounters where this device was used during a preventive or wellness visit. Pull claims from the past 12 months where the Gravlee Jet Washer was billed alongside a preventive care code. If the documentation doesn't show an independent symptomatic indication, those claims are vulnerable on audit. |
| 3 | Brief your gynecology billing staff on the §1862(a)(7) exclusion. This statutory exclusion isn't new, but the policy modification makes it worth a refresher. Anyone reviewing these claims needs to understand that "no symptoms" means "no payment" — regardless of clinical intent. |
| 4 | Confirm your charge capture reflects the diagnostic indication, not just the procedure. Because NCD 163 does not list specific CPT or HCPCS codes, your coding team is likely mapping this to general diagnostic procedure codes. Make sure the diagnosis codes attached to those claims reflect the symptomatic presentation. |
| 5 | Review the cross-referenced NCD on the Vabra Aspirator (NCD 230.6). CMS explicitly links these two policies. The Vabra Aspirator NCD covers a similar device used for endometrial sampling. If your practice bills for both devices, the coverage logic is parallel — symptomatic patients only, no routine screening. |
| 6 | Consult your Medicare Administrative Contractor if you have questions about local billing guidelines. NCD 163 is a national policy, but your MAC may have additional local coverage determination guidance or billing instructions that apply in your region. When in doubt, call your MAC before the effective date. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for the Gravlee Jet Washer Under NCD 163
Covered Codes (When Medical Necessity Criteria Are Met)
NCD 163 does not list specific CPT, HCPCS, or ICD-10 codes. CMS has not assigned dedicated codes to the Gravlee Jet Washer in this policy document.
Your billing team should work with your coding staff to identify the appropriate diagnostic procedure codes your practice currently uses for this service. The coverage policy applies to the device itself and to related diagnostic services — the code set you use needs to be internally consistent and documented.
Do not fabricate or assume codes based on similar devices. If you're unsure which codes apply to your specific claim scenario, contact your MAC or consult a certified medical coder with gynecologic billing experience.
Cross-Reference Note
CMS directs billing teams to two additional resources:
- NCD 230.6 — Vabra Aspirator: Covers a similar endometrial sampling device under the same symptomatic-patient-only standard. Review this NCD if your practice bills for the Vabra Aspirator alongside or instead of the Gravlee Jet Washer.
- Medicare Benefit Policy Manual, Chapter 16, §90: Contains additional guidance on the statutory exclusion for routine checkups under §1862(a)(7). If your compliance officer is reviewing this policy, start there.
What This Policy Change Actually Means for Your Practice
The modification to NCD 163 doesn't introduce new coverage categories or change the reimbursement structure. What it does is reaffirm a sharp boundary that already existed. CMS is telling you — again — that this device is diagnostic, not preventive. Payment follows symptoms.
The risk profile here is moderate but real. Gynecology practices that use this device regularly are most exposed. If any part of your workflow routes the Gravlee Jet Washer into wellness visits or annual exams, you're building a claim denial pattern that an audit will find.
The billing guidelines are clear. Document the symptom. Don't bill asymptomatic patients. Cross-check with NCD 230.6 if you also use the Vabra Aspirator. And if your compliance officer hasn't looked at this policy in the past year, the March 7, 2026 effective date is a good reason to put it on the agenda.
