What You Should Know:
– Out-of-network ground ambulance rides accounted for a larger percentage of ground ambulance claim lines1 than in-network rides from 2018 to 2022. In 2022, out-of-network transport accounted for 59.4% of all ground ambulance claim lines, while in-network transports made up 40.6% of the distribution, according to other findings reported in a FAIR Health brief released today, A Window into Utilization and Cost of Ground Ambulance Services: A National Study of Private Healthcare Claims.
– There was a slight decrease in out-of-network transports during this period: Out-of-network rides made up 63.7% of all ground ambulance claim lines in 2018 compared to 59.4% in 2022. In addition, individuals aged 65 and older experienced higher rates of ground ambulance rides resulting in inpatient admission than any other age group in the period 2018-2022; 52.0 percent of male patients and 47.9% of female patients in that age group were admitted to a hospital after ground ambulance transport.
Report Key Findings
FAIR Health drew on its repository of billions of private healthcare claims to shed light on both emergency and nonemergency ground ambulance services across the nation in the period 2018 to 2022. The report examines utilization, cost, age and gender, diagnosis, differences across states and outcomes associated with ground ambulance transport (e.g., inpatient admission).
Among the key findings:
- Throughout the period 2018-2022, advanced life support (ALS) services, which can provide a higher level of care than basic life support (BLS) services, accounted for a slightly larger percentage of ground ambulance claim lines than BLS services. For example, in 2022, 51.1 percent of ground ambulance claim lines were associated with ALS compared to 48.9 percent associated with BLS.
- Emergency transport was more common than nonemergency transport for both ALS and BLS ground ambulance services from 2018 to 2022.
- In 2022, average allowed amounts2 were consistently higher for ALS ground ambulance services than for BLS services, though costs varied by state.
- Individuals 65 years and older were the largest age group associated with both ALS and BLS ground ambulance services among the commercially insured and Medicare Advantage population, though their share of ALS ground ambulance claim lines decreased from 37.4 percent in 2018 to 30.6 percent in 2022 and their share of BLS ground ambulance claim lines decreased from 47.5 percent to 40.9 percent in 2022.
- In addition to being used for transport, ground ambulances can provide on-site treatment, without transporting the patient from the original location to a hospital.3 Such treatment increased from 2018 to 2020, rising from 1.4 percent to 2.0 percent of all ground ambulance claim lines, but decreased slightly in the following years, dropping to 1.9 percent by 2022.
- From 2018 to 2022, response and treatment without transport accounted for a higher percentage of ground ambulance claim lines among individuals aged 19 to 35 than any other age group: between 2.2 and 3.1 percent. By comparison, the age cohort 65 years and older had the lowest percentage.
- General signs and symptoms were the most common diagnosis associated with the various ground ambulance types (ALS, BLS and response and treatment—no transport) evaluated from 2018 to 2022.
- General signs and symptoms involving circulatory and respiratory systems were the second most common reason for ground ambulance services among the top diagnoses for ALS services, non-transport services and all services involving transport (i.e., excluding no transport).
- Mental health conditions accounted for the third largest share of BLS ground ambulance claim lines; this diagnosis was eighth on the lists for ALS services and all services involving transport, and sixth on the list for response and treatment—no transport services.
- From 2018 through 2022, the five states with the highest average mileage for ground ambulance transport were Vermont (33.8 miles), Maine (30.6 miles), Wyoming (25.0 miles), North Dakota (24.6 miles) and Mississippi (23.8 miles). The jurisdictions with the lowest average ground ambulance mileage were Washington, DC (7.9 miles); Alaska (8.8 miles); New York (9.1 miles); Nevada (9.4 miles); and Massachusetts (9.9 miles).
- The five states with the highest average allowed (in-network) amounts for ground ambulance mileage per statute mile in 2022 were Utah ($28.35), Wyoming ($24.29), California ($20.63), North Dakota ($19.36) and Nevada ($18.76). The lowest average allowed amounts for ground ambulance mileage per statute mile in 2022 occurred in Florida ($5.79), Maine ($7.55), North Carolina ($7.66), Vermont ($7.71) and Maryland ($8.21).
- From 2018 to 2022, out-of-network ground ambulance rides accounted for a larger percentage of total ground ambulance claim lines than in-network rides, though there was a slight decrease in out-of-network services during this period. Out-of-network rides made up 63.7 percent of all ground ambulance claim lines in 2018 and 59.4 percent in 2022.
- For nonemergency ground ambulance services, the percentage of in-network versus out-of-network nonemergency ground ambulance services was fairly even from 2018 to 2022. In-network rides accounted for 48.6 percent to 51.3 percent of nonemergency ground ambulance claim lines during this period and out-of-network rides made up 48.7 percent to 51.4 percent.
- Emergency ground ambulance services were more frequently rendered out of network than in network, though the percentage of out-of-network rides declined from 2018 to 2022. In 2018, out-of-network services accounted for 68.3 percent of emergency ground ambulance claim lines, but by 2022, their share of the distribution decreased to 62.0 percent.
- Both males and females aged 65 and older experienced higher rates of ground ambulance rides resulting in inpatient admission than any other age group in the period 2018-2022; 52.0 percent of male patients and 47.9 percent of female patients in that age group were admitted to a hospital after ground ambulance transport.
1 “Claim lines” are the individual procedures or services listed on an insurance claim.
2 An allowed amount is the total fee negotiated between an insurance plan and a provider for an in-network service; the allowed amount includes both the insurer’s and the member’s share of the total fee.
3 For example, on-site treatment may be provided when the patient refuses to be transported to a hospital.
