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

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

Key Findings

NORTHWEST AMBULATORY SURGERY CENTER LLC is billed under the Ambulatory Surgical Clinic/Center taxonomy in PORTLAND, OR and has been enumerated since 2008-10-22 (~18 years ago), indicating a long-standing Medicare billing presence. Its Medicare lifetime revenue is $1.1M and there is no Medicaid billing on file, so operational insights should be interpreted through a Medicare-only lens.

Revenue is highly concentrated in a small number of high-value orthopaedic procedures: 27447 accounts for $596.4K (54.2% of Medicare revenue), 27130 accounts for $285.7K (26.0%), and 23430 accounts for $36.5K (3.3%); the precomputed top-3 codes collectively represent 83.5% of this provider's total Medicare revenue. This concentration identifies lower-extremity joint arthroplasty as the core revenue driver.

The provider is effectively single-payer in practice: Medicare accounts for the entire recorded public-payer revenue ($1.1M) while there is no Medicaid billing on file. That payer mix implies the center's volume, cash flow, and reimbursement sensitivity are tied to Medicare policy and beneficiary referrals rather than state Medicaid dynamics.

Competitive standing for the top Medicare procedures is mixed. For knee arthroplasty 27447 the provider ranks #1732 of 12089 nationally (85th percentile) but is described as having "typical, unremarkable volume for this code," suggesting above-average placement by rank without being an extreme outlier; for hip arthroplasty 27130 the provider ranks #2702 of 8062 (65th percentile) and likewise shows "typical, unremarkable volume for this code," indicating a solid but not dominant national position.

Procedure mix beyond arthroplasty indicates a broad outpatient orthopaedic and ambulatory surgery footprint: arthroscopic shoulder and knee codes (29828, 29827, 29881, 29880) appear in the top codes alongside hand procedures (64721, 26055), spine injections (62323, 64493), and fat grafting (15771). This pattern suggests the center performs both major joint replacements and a range of same-day orthopaedic and soft-tissue procedures, consistent with an ambulatory surgery center model.

There are notable statistical features in the Medicare code set that warrant attention. C9290 shows 17K claims at $1 avg paid/claim for $17K total (1.5% of Medicare revenue) and ranks #93 of 451 (80th percentile) — described as "typical, unremarkable volume for this code" — while 23430 contributes $36.5K (3.3% of revenue) but ranks #727 of 811 (0th percentile) and is also labeled "typical, unremarkable volume for this code," highlighting that some smaller-value codes can have peer-rank patterns that look anomalous in isolation.

Because more than four-fifths of Medicare revenue (83.5%) is concentrated in the top three CPT/HCPCS codes, the center's financial performance is sensitive to reimbursement changes, payer negotiations, or referral shifts affecting lower-extremity arthroplasty. Payer analysts should prioritize monitoring Medicare payment policy and regional orthopedic referral flows for knee and hip replacement when assessing this entity's revenue stability.

Several less-revenue items nevertheless signal service breadth and potential ancillary referral streams: injection and fluoroscopy codes (62323, 64493, 76000) and outpatient hand surgeries (64721, 26055) together account for modest shares of revenue but imply ancillary procedural volume that could support cross-referral opportunities or upsell of perioperative services. These ancillary lines may blunt some volatility from the highly concentrated arthroplasty revenue base.
