Surgery centers are busier than ever, and so are the questions about what they get paid. Payers, providers, and employers all want to know if a rate is fair. That is where ASC benchmarks come in.
This guide explains ASC rate benchmarking from the ground up. You will learn what it means, why it matters in 2026, and how to act on it.
We keep things simple and define each term the first time it appears. By the end, you will know how to compare your surgery center's rates with confidence.
Why ASC Rate Benchmarking Matters More Than Ever
An ambulatory surgery center, or ASC, is a facility where patients have same-day surgery and go home the same day. These centers are growing fast, both in number and in dollars.
Consider ASC industry revenue growth: Ambulatory surgery centers (ASCs) generated $45 billion in revenue in 2024, a figure projected to climb to $57 billion by 2030.
That growth makes strong ASC benchmarks more valuable each year. A fair rate today may lag the market tomorrow.
At the same time, new pricing rules are arriving. Meanwhile, hospital price transparency enforcement is ramping up: Enforcement of new and updated Hospital Price Transparency (HPT) requirements finalized in the CY 2026 Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) Payment System final rule starts April 1, 2026.
More revenue and more transparency mean more scrutiny. Every stakeholder now expects clear proof that a rate is reasonable.
Payers use rate comparisons to build fair networks. Employers use them to control benefit costs. Providers use them to protect margins at the negotiating table.
Knowing how your rates stack up is no longer a nice-to-have. It is the starting point for almost every payment decision.
What Is ASC Rate Benchmarking?
ASC rate benchmarking is the practice of comparing your surgery center's negotiated and Medicare rates against peers, payers, and local markets. A benchmark is simply a reference point you measure against.
The comparison tells you whether a rate is high, low, or about average. It turns a single number on a contract into useful context.
These comparisons rely on real pricing data. Much of it now lives in healthcare price transparency data that payers and hospitals publish each month.
Rate benchmarking is not the same as clinical, operational, or financial KPI benchmarking. Those track quality, efficiency, or profit. Rate benchmarking looks only at the prices you are paid for each procedure.
That focus keeps the work clear. Good ASC benchmarks answer one question: is this price competitive for this procedure in this market?
The Policy Backdrop: CMS CY2026 and the HOPD-vs-ASC Gap
Medicare sets a baseline that shapes the whole market. Each year, the Centers for Medicare & Medicaid Services (CMS) updates how much it pays ASCs.
The CMS CY2026 ASC payment update: For CY 2026, using the hospital market basket update, CMS finalized an update factor to the ASC rates of 2.6%. The update applies to ASCs meeting relevant quality reporting requirements.
A hospital outpatient department, or HOPD, is the outpatient surgery area inside a hospital. Medicare often pays more for the very same procedure in an HOPD than in an ASC.
That difference is called the HOPD-versus-ASC gap. The Medicare ASC-vs-HOPD rate gap is wide: In 2024, Medicare paid ASCs, on average, 62% of hospital outpatient department (HOPD) rates for the same procedures.
Federal advisors see the same pattern. The MedPAC 2025 ASC status report notes that "for most services, the ASC payment rates are 46 percent lower than the HOPD payment rates".
This gap is why site of service matters so much. The same code can pay very differently depending on where the surgery happens.
The gap also shapes commercial contracts, not just Medicare. Many private payers anchor their rates to Medicare, then add a markup. So a wide public gap often points to a wide private one as well.
Why Most ASCs Can't Easily See How Their Rates Compare
The data exists, but it is hard to use. Payers and hospitals publish machine-readable files, or MRFs, which are large computer files that list negotiated prices.
These files are huge and messy. Formats differ from payer to payer, and a single file can hold millions of rows.
Commercial rates sit buried across thousands of separate payer files. Finding one procedure means digging through data never built for easy reading.
To compare fairly, you must match the same billing code, in the same market, at the same site of service. Miss any one of those, and the comparison breaks.
Most procedures use a shared billing code called a CPT or HCPCS code. These codes let you line up the same surgery across many payers. Still, payers describe rates in different ways, so a raw match rarely tells the full story.
That effort is why many centers cannot see ASC vs. hospital outpatient rates side by side. Without a way to clean the files, useful ASC benchmarks stay out of reach.
What Benchmarking Reveals: Variation by Ownership, Payer, and Market
Once the data is organized, clear patterns appear. Rates vary by who owns the center, which payer is involved, and where the center sits.
Ownership type is often the biggest driver. Independent centers, management-company centers, and health-system-owned centers can negotiate very different prices for identical work.
The table below shows the main dimensions rate benchmarking exposes. Each one changes how a number should be read.
| Benchmark Lens | What It Reveals | Strategic Read |
|---|---|---|
| Ownership | Independent, management-company, and health-system-owned ASC pricing patterns | Peer comparisons only work when the ownership model is part of the context. |
| Payer | Rate differences from one insurer to the next for the same procedure | A single below-market payer can quietly pull down revenue across high-volume codes. |
| Market | Local variation across regions, cities, and nearby surgery centers | Nearby ASCs may earn materially different rates for the same service. |
| Site of Service | ASC pricing compared with hospital outpatient department pricing | The same code can carry a very different reimbursement story depending on setting. |
Rates are not the only thing that moves. Collections rise too, as ASC operational benchmarks show: From 2024 to 2025, ASC net collection rates increased from 81% to 87% as an overall average.
Read together, these dimensions turn a flat rate into a full story. Strong ASC benchmarks tell you not just what you earn, but why.
ASC Benchmarks at a Glance: What the Data Shows
Here is a quick preview of what full rate benchmarking can uncover. These figures come from Gigasheet's price transparency dataset.
- Colonoscopy facility rates spread 1.8x between the lowest and highest payer median.
- 358.9M rate records
- 7,427 ASCs
- All 50 states
Across 7,427 ASCs in all 50 states, Gigasheet's ASC benchmarks show colonoscopy facility rates spanning 1.8x from lowest to highest payer median. Full benchmarking turns that spread into clear, center-level insight you can act on.
Action Steps: Turning ASC Benchmark Data Into Decisions
Data only helps when it drives action. Use these steps to move from numbers to negotiations.
How to turn ASC benchmarks into decisions
Preparation is what creates leverage. Learning how to benchmark market rates puts real evidence on your side.
Gigasheet built its price transparency for providers tools for exactly this work. The goal is to make each step faster and better supported.
How Gigasheet Turns Price Transparency Data Into ASC Benchmarks
Gigasheet cleans up messy MRF data so your team does not have to. It normalizes files from many payers into one consistent, comparable view.
From there, you see percentile bands that show where each rate falls against the market. The Price Transparency Explorer makes this fast and visual.
Every number traces back to its original source file. That drill-to-source design, along with provider rate scores, keeps your ASC benchmarks clear and trustworthy.

These short answers recap the key ideas covered above.
What Is ASC Rate Benchmarking?

How Does ASC Pay Compare To Hospital Pay For The Same Procedure?
According to the ASC Association, Medicare paid ASCs on average 62% of HOPD rates in 2024. MedPAC reports ASC rates run about 46% lower than HOPD for most services.
Where Does ASC Rate Benchmark Data Come From?
Benchmark data comes from payer and hospital machine-readable files, known as price transparency data, plus CMS ASC and OPPS payment rates.
