CMS Modified NCD 163 for the Gravlee Jet Washer, Effective March 7, 2026 — Here's What Billing Teams Need to Know
The Centers for Medicare & Medicaid Services modified NCD 163, the National Coverage Determination governing Medicare coverage of the Gravlee Jet Washer, effective March 7, 2026. This coverage policy applies to a sterile, disposable device used to detect endometrial cancer — and the medical necessity rules here are strict. The policy does not list specific CPT or HCPCS codes, so your billing team needs to pay close attention to the clinical criteria driving coverage vs. denial.

CMS Gravlee Jet Washer Coverage Criteria and Medical Necessity Requirements 2026
NCD 163 in the CMS Medicare system covers the Gravlee Jet Washer as a diagnostic device for detecting endometrial cancer. Coverage depends entirely on one factor: the patient must show clinical symptoms or signs of endometrial disease before the procedure is performed.
The policy defines qualifying symptoms as irregular or heavy vaginal bleeding. That's the standard. If the patient presents with those symptoms, the device and related diagnostic services are eligible for Medicare reimbursement.
Medical necessity here isn't a checkbox — it's the entire gate. CMS won't pay if the patient is asymptomatic, period. This is one of the cleaner bright lines you'll see in a coverage policy. There's no gray area about severity, frequency, or duration of symptoms. The patient either has clinical symptoms of endometrial disease or they don't.
The CMS Gravlee Jet Washer coverage policy classifies this under the Diagnostic Tests (other) benefit category. That classification matters for how you route the claim and what documentation your team needs to support the medical necessity determination before the claim goes out the door.
Prior authorization requirements are not specifically addressed in NCD 163. However, given the strict symptom-based criteria, your documentation needs to be airtight before billing. If your Medicare Administrative Contractor has issued a local coverage determination that adds requirements on top of this NCD, those MAC-level rules take precedence for your region. Check with your MAC before assuming the NCD is the only standard in play.
CMS Gravlee Jet Washer Exclusions and Non-Covered Indications
The policy makes one exclusion crystal clear: the Gravlee Jet Washer is not covered when used on asymptomatic patients.
CMS cites §1862(a)(7) of the Social Security Act, which prohibits Medicare payment for routine physical examinations. The Gravlee Jet Washer falls under that prohibition when the clinical justification is screening rather than diagnosis driven by symptoms. This isn't a gray-area exclusion — it's statutory.
The real issue here is documentation. The clinical and billing record needs to show that the patient had active symptoms at the time of the encounter. If your documentation says "routine exam" or doesn't reference irregular or heavy bleeding, the claim will get denied. This is the most common claim denial risk associated with this policy, and it's entirely preventable.
Don't assume the ordering provider's notes will cover you automatically. Your billing team needs to verify the symptom documentation is present and specific before submitting.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Symptomatic patient with irregular or heavy vaginal bleeding, evaluated for endometrial cancer | Covered | No specific codes listed in NCD 163 | Documentation of symptoms required to support medical necessity |
| Asymptomatic patient — routine physical exam or screening | Not Covered | N/A | Excluded under §1862(a)(7) of the Social Security Act; routine exam payment is precluded by statute |
CMS Gravlee Jet Washer Billing Guidelines and Action Items 2026
The billing guidelines for NCD 163 are straightforward, but they demand precision. Here's what your team should do before March 7, 2026, and on every claim going forward.
| # | Action Item |
|---|---|
| 1 | Audit your documentation workflow before the effective date of March 7, 2026. Confirm that every Gravlee Jet Washer claim has a corresponding note documenting the patient's symptoms — specifically irregular or heavy vaginal bleeding. No symptoms, no coverage. |
| 2 | Train your coders on the asymptomatic exclusion. This is the single biggest claim denial risk under NCD 163. If a coder sees a routine gynecologic visit and doesn't flag the missing symptom documentation, the claim will be denied on medical necessity grounds. Make this part of your standard pre-bill audit checklist. |
| 3 | Check with your Medicare Administrative Contractor for any regional LCD layered on top of NCD 163. The NCD sets the floor, but your MAC may have issued a local coverage determination with additional documentation or coding requirements. Don't assume the NCD is your only standard. |
| 4 | Confirm code assignment with your MAC or compliance officer. NCD 163 does not list specific CPT or HCPCS codes. That gap creates real billing risk. Your MAC can clarify which procedure and service codes apply to Gravlee Jet Washer claims in your region. If you're not sure how to code this, talk to your compliance officer or billing consultant before submitting. |
| 5 | Cross-reference NCD 230.6 (Vabra Aspirator) if you bill both devices. CMS explicitly cross-references the Vabra Aspirator NCD in this policy. The coverage logic is similar — symptomatic patients only, no routine screening. If your practice bills both devices, apply the same documentation standard across both. A denial on one is often a signal to audit the other. |
| 6 | Review Chapter 16, §90 of the Medicare Benefit Policy Manual. CMS references this section directly in NCD 163. It covers noncovered services and exclusions under the Act. If your billing team hasn't read it, now is the right time — especially the provisions around routine exams under §1862(a)(7). |
| 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 CPT and HCPCS Codes
The policy data for NCD 163 in the CMS Medicare system does not list specific CPT or HCPCS codes. CMS has not assigned a designated billing code within this NCD.
This is unusual and creates real reimbursement uncertainty. Your billing team should not guess at codes. Contact your MAC directly to confirm which procedure codes apply to Gravlee Jet Washer claims in your jurisdiction.
Key ICD-10-CM Diagnosis Codes
NCD 163 does not list specific ICD-10-CM codes. However, given the coverage criteria — symptoms of endometrial disease such as irregular or heavy vaginal bleeding — your diagnosis coding should reflect those clinical presentations. Work with your clinical documentation team to ensure the ICD-10 codes on the claim align with the symptom-based medical necessity standard.
Common relevant diagnosis categories would involve abnormal uterine bleeding or suspected endometrial pathology, but your compliance officer or coding consultant should confirm the appropriate codes for your specific patient scenarios. Don't submit claims with diagnosis codes that suggest routine screening or an asymptomatic encounter — those will trigger denials under §1862(a)(7).
