GREENWICH EMERGENCY MEDICAL SERVICE, INC. bills almost exclusively for ambulance transport services: its Medicare and Medicaid top revenue drivers are A0427 (ALS1 emergency transport), A0429 (BLS emergency transport), and A0425 (ground mileage), indicating the operation is focused on emergency ground transport rather than ancillary or specialty outpatient services. The presence of both ALS and BLS emergency codes as the leading claims shows it provides a mix of advanced and basic life-support transports rather than a single-level service model.
Revenue is highly concentrated in a few transport codes on both payers: the top 3 Medicare codes account for 98.6% of this provider's Medicare revenue and the top 3 Medicaid codes account for 99.9% of its Medicaid revenue. This concentration underscores that nearly all billed revenue flows from emergency transport and mileage CPT/HCPCS rather than a broader portfolio of services.
On payer mix and scale, this provider reports $734.3K in total Medicare revenue versus $1M in total Medicaid revenue, making Medicaid the larger single payer by reported dollars. The existence of material revenue from both programs indicates a mixed payer exposure, but Medicaid represents the larger share of this entity's public-pay revenue base.
Against national Medicare peers the provider posts relatively high percentile ranks on its leading Medicare transport codes while still being described as 'typical, unremarkable volume.' For Medicare A0427 the provider generated $478.2K (65.0% of Medicare revenue) with 1.1K claims and a national rank of #660 of 6841 (90th percentile, typical, unremarkable volume), and for A0429 it reported $209.4K (28.5% of Medicare revenue) with 585 claims and rank #954 of 7808 (88th percentile, typical, unremarkable volume).
Within Connecticut Medicaid peer comparisons the provider occupies upper-middle in-state positions for its two largest codes but remains described as typical: A0429 produced $494.1K (49.1% of Medicaid revenue) over 3.1K claims and ranks #42 of 122 in-state (66th percentile, typical, unremarkable volume), while A0427 produced $477.6K (47.5% of Medicaid revenue) over 2.8K claims and ranks #25 of 80 in-state (70th percentile, typical, unremarkable volume).
Operational utilization patterns point to high transport volume with modest per-claim payouts: Medicare A0427 shows 1.1K claims at $427 avg paid/claim (total $478.2K) and A0429 shows 585 claims at $358 avg paid/claim (total $209.4K); Medicaid A0429 shows 3.1K claims at $161 avg paid/claim (total $494.1K) while Medicaid A0427 shows 2.8K claims at $168 avg paid/claim (total $477.6K). Ground mileage is a secondary but consistent revenue stream with 5.3K Medicare mileage claims at $7 avg paid/claim ($37.1K) and 5.5K Medicaid mileage claims at $6 avg paid/claim ($32.7K).
The provider has an established tenure in the NPI registry (enumerated 2006-07-22, ~20 years ago), which supports interpretation of the observed billing patterns as stable-service operations rather than a transient or newly formed supplier. Longevity combined with concentrated transport billing suggests a steady emergency-ambulance business rather than a rapidly diversifying clinical enterprise.
Despite meaningful revenue, code diversity is very limited and some codes are negligible: the top three codes nearly entirely explain revenue for both payers, A0433 (ALS2) contributes only $10.5K to Medicare (1.4% of Medicare revenue) and an in-state Medicaid-only code 4701Y contributes $1.1K (0.1% of Medicaid revenue) and ranks #11 of 12 in-state (9th percentile, typical, unremarkable volume). This narrow code mix signals dependence on emergency transport services and implies sensitivity to rate or utilization changes for those few codes.
