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 Hawaii for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Hawaii 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. Hawaii (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.

CASTLE MEDICAL CENTER reports no Medicare billing on file and $37.6M in lifetime Medicaid revenue, making its public payer footprint effectively single-payer (Medicaid)-dominated based on the available data. Analysts should treat Medicaid as the primary revenue source when modeling this facility’s payer mix or forecasting cash flows.

Revenue is highly concentrated in emergency department evaluation-and-management codes: 99285 ($11.4M, 31.5%), 99284 ($8M, 22.1%), and 99283 ($7.3M, 20.2%) together account for 73.8% of the provider’s total Medicaid revenue. This concentration indicates the ED is the primary revenue driver for the hospital under Medicaid.

The code mix points to an ED-centric acute-care operation with substantial diagnostic and short-term critical care capability. High-revenue ED codes (99285/99284/99283) combined with notable CT abdomen/pelvis billing (74177, $3M; 74176, $927.4K) and critical care (99291, $915.2K) suggest the hospital provides high-throughput emergency evaluation supported by on-site imaging and urgent inpatient-level interventions.

On statewide competitive standing for ED services, Castle is an above-average but not dominant participant: 99285 ranks #8 of 39 providers in-state (82th percentile), 99284 ranks #12 of 47 (76th percentile), and 99283 ranks #11 of 45 (77th percentile). Each of these ED codes is described in the file as "typical, unremarkable volume for this code," implying the hospital has steady, above-median ED volumes without being the clear market leader.

Castle shows pockets of relative strength in selected diagnostic services beyond ED billing. For example, 93306 (echocardiography) is ranked #5 of 59 providers in-state at the 93th percentile while generating $229.7K (0.6% of Medicaid revenue), and U0003 (SARS-CoV-2 NAAT) ranks #4 of 19 (83th percentile) with $372.3K (1.0% of revenue); both listings are flagged as "typical, unremarkable volume for this code" despite high percentile placement.

Ancillary outpatient and lab services contribute meaningfully at lower revenue tiers, indicating integrated diagnostic throughput: 80061 (lipid panel) $299.9K, 80307 (drug screen) $264.7K, 87491 (Chlamydia NAAT) $221.8K, and 70450 (CT head without contrast) $136.9K. These items support the profile of a full-service acute hospital handling both ED diagnostics and routine outpatient testing under Medicaid.

The extreme concentration of Medicaid revenue in three ED codes (73.8% of Medicaid revenue) makes the provider’s Medicaid performance sensitive to changes in ED utilization patterns or policy adjustments to ED reimbursement. For payer contracting and utilization-management scenarios, small shifts in ED visit volumes or payment rates could have outsized effects on overall Medicaid revenue.

Castle’s NPI tenure—enumerated on 2005-10-26 (~21 years ago)—indicates an established presence in the Kailua market, which should be considered when assessing competitive dynamics and potential referral relationships in-state.
