Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Connecticut for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Connecticut only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Connecticut (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

GREENWICH HOSPITAL is effectively a Medicaid-centric facility in this dataset: it has no Medicare billing on file while reporting $46.4M in total Medicaid revenue, indicating the provider’s observable payer footprint here is dominated by Medicaid rather than Medicare. This makes the hospital functionally single‑payer in the available data and concentrates analytic attention on Medicaid service lines and utilization patterns.

Revenue concentration is high: the top three Medicaid billing codes account for 51.0% of the provider’s total Medicaid revenue, signaling dependence on a small set of services for over half of Medicaid receipts. That concentration suggests financial sensitivity to reimbursement or utilization changes for those leading codes.

Emergency department services are a major driver of Medicaid revenue. High‑revenue E/M codes 99284 ($6.3M, 16.8% of Medicaid revenue), 99285 ($5.3M, 14.1%), and 99283 ($4.5M, 12.0%) together represent a substantial portion of the hospital’s case mix and revenue, indicating the hospital operates a busy ED that handles a spectrum of acuity from low to high complexity.

Outpatient clinic activity (G0463) is also a top revenue source: G0463 generated $7.6M (20.0% of Medicaid revenue) and ranks #12 of 35 in-state (68th percentile). This position reflects solid, though not dominant, outpatient clinic volume relative to Connecticut peers and reinforces a mixed ED-and-outpatient operating model.

Service-line mix includes significant procedural and infusion activity beyond ED and clinic visits. High claim volumes for physical therapy codes such as 97110 (48.6K claims, $3M, 8.0% of revenue) and large counts for infusion/IV administration codes (96374, 96361, 96365; combined revenue contributions across the top 25) indicate integrated rehabilitation and infusion services supporting the hospital’s outpatient and ED care pathways.

For competitive standing within Connecticut, most top Medicaid codes place GREENWICH HOSPITAL in typical to above‑typical percentiles but not as a statewide leader. Examples include 99284 at the 71st percentile and 99285 at the 67th percentile, while 97110 is relatively strong at the 93rd percentile; these rankings portray the hospital as a meaningful regional player on several services but not the dominant provider for most high‑volume codes.

Tenure is long: the provider’s NPI was enumerated on 2006-01-26 (approximately 20 years ago), indicating an established presence in the market which aligns with its broad outpatient, ED, therapy, and infusion service footprint shown in Medicaid claims. This longevity supports expectation of mature operational structures for the observed service lines.

Several codes show unusually high average paid per claim relative to claim counts and revenue mix, suggesting higher unit reimbursements for specific procedures: for example, 95004 averages $4286/claim for $488.6K revenue (1.3% of Medicaid revenue) despite only 114 claims, and J0485 ranks #3 of 3 in-state with $307.8K revenue (0.8%). These items reflect niche, high‑unit‑cost services that contribute meaningfully to revenue despite low volumes.
