The Centers for Medicare & Medicaid Services just announced a nationwide six-month moratorium on new Medicare enrollments for hospices and home health agencies (HHAs) as part of a major anti-fraud initiative coordinated with Vice President JD Vance’s Anti-Fraud Task Force.
The PWW Advisory Group has reviewed the release from CMS, which signals to the ambulance industry, that CMS is increasingly willing to use aggressive enrollment controls in provider categories it considers “high fraud risk.” Ambulance providers should pay attention because CMS has already used the moratorium tool against nonemergency ambulance suppliers in the past — particularly in areas like Dallas, Houston, Philadelphia, Newark, and Chicago.
CMS imposed temporary enrollment moratoria on new nonemergency ambulance suppliers because of fraud concerns tied largely to repetitive dialysis transport and questionable medical necessity.
The major implications for ambulances are likely the following:
1. CMS Is Expanding the “Fraud Prevention Before Enrollment” Model
For ambulance providers, particularly nonemergency providers, this raises the possibility of:
- Future regional ambulance moratoria;
- Heightened screening for new ambulance enrollments;
- Stricter ownership-change reviews; and
- More aggressive site visits for new enrollment and revalidation.
2. Nonemergency Ambulance Remains a Historic Fraud Target
CMS and OIG have long identified repetitive BLS dialysis transports as a fraud hotspot. Common historic allegations include: medically unnecessary dialysis transports; cloned PCS forms; “bed confined” boilerplate language; kickback relationships with facilities; and transports that could have occurred by wheelchair van. Because of that history, ambulance remains vulnerable to future moratoria if CMS sees geographic spikes, unusual utilization, and billing anomalies.
3. Ownership Changes Could Become a Bigger Issue
One important sentence in the announcement: “The moratoria will apply to all applications for initial Medicare enrollment and certain changes in majority ownership…”Ambulance companies involved in acquisitions, PE rollups, management agreements, rapid expansion, or seller-financed ownership transitions may face heightened scrutiny.
4. Expect More Data-Driven Ambulance Analytics
Potential future ambulance metrics CMS could target:
- Dialysis utilization rates;
- Transport frequency per beneficiary;
- PCS physician patterns;
- Mileage outliers;
- High ALS billing ratios;
- hospice ambulance utilization; and
- SNF transport relationships.
5. Increased Site Visits and Operational Verification
For ambulance providers, that could evolve into more surprise site inspections during revalidation (right now, some MAC agencies give you a heads up), and even enhanced vehicle verification (listed on 855, inspected), and staffing verification.
6. Dialysis and SNF Relationships Will Continue to Receive Attention
This announcement reinforces a broader federal theme: high-volume, recurring transport/service relationships are viewed as fraud sensitive. That includes ambulance relationships involving dialysis centers, SNFs, hospice providers, and behavioral health facilities. The government continues to scrutinize arrangements that create incentives for volume generation, steering, discounted services, and "swapping."
Strategic Takeaways for Ambulance Providers
For ambulance providers, especially nonemergency providers, now is the time to:
- Tighten PCS compliance;
- Audit repetitive transport programs;
- Closely validate medical necessity documentation;
- Prepare for site visits and enhanced screening (make sure staff know what to expect and that it could be unannounced); and
- Ensure facility relationships withstand AKS scrutiny.
