Five healthcare cost estimator tools compared: CMS, FAIR Health, Healthcare Bluebook, Turquoise Health, and Sylk Health. Plus how to use price transparency data.
Hospital bills in the United States vary by as much as 39 times for the same procedure within the same metro area, according to a Patient Rights Advocate analysis (opens in new tab). A coronary bypass ranges from $27,683 to $247,902 depending on the hospital and insurer, per the same report. A common blood test costs $18 in Toledo, Ohio and $443 in Beaumont, Texas.
These aren't different procedures. They're the same procedure, at different hospitals, sometimes minutes apart.
Healthcare cost estimator tools exist to close that gap. But most patients don't know they exist, and the ones that do exist have significant limitations. Here's a practical comparison of every major tool available, what each one does well, and where each one falls short.
Information current as of April 2026.
Since January 1, 2021, the CMS Hospital Price Transparency rule (opens in new tab) requires every US hospital to publish two things:
A comprehensive machine-readable file listing all items, services, and negotiated rates with every insurer
A consumer-friendly display of at least 300 shoppable services with prices
In practice, compliance is weak. A 2024 HHS Office of Inspector General audit (opens in new tab) found that 46% of 5,879 hospitals don't comply with the rule. The Patient Rights Advocate's November 2024 report (opens in new tab) found only 21.1% of 2,000 reviewed hospitals in full compliance - down from 34.5% in February 2024. Major health systems with 0% compliance include HCA Healthcare, Tenet Healthcare, and UPMC.
The federal government has issued penalty notices to just 15 hospitals in four years (opens in new tab). Only one penalty notice was issued in 2024.
The data that does exist is valuable. But finding and using it requires tools.
What it covers: A database of over 52 billion healthcare claim records, updated with 4 billion new records annually. Covers both in-network and out-of-network pricing for 100 common procedures by geographic area.
How to use it: Visit consumer.fairhealth.org (opens in new tab). Search by procedure or diagnosis code and zip code. The tool returns estimated insurer-paid amounts and provider charges for your area.
Strengths: Largest claims database in the US. Independent nonprofit. Free to use. Good for understanding what insurance typically pays for a procedure in your zip code.
Limitations: Shows averages, not hospital-specific prices. Doesn't include international pricing. Won't tell you that the hospital down the street charges 3x what the one across town charges.
What it covers: Cost and quality information for 4,000+ facilities and 500,000+ providers. Quality rankings for 200+ procedures.
How to use it: Visit healthcarebluebook.com (opens in new tab). Search by procedure. The tool calculates a "Fair Price" from its independent nationwide payment database and color-codes facilities: green (lowest cost), yellow, red (highest cost).
Strengths: Combines price and quality data. Reports average savings of $1,500 per procedure (opens in new tab) for patients who use the platform. Employers using it report up to 12% reduction in total medical spending.
Limitations: Primarily designed for employer-sponsored plans. Consumer access may require employer enrollment. US-only pricing.
What it covers: Over 1 trillion records of provider, payer, professional, drug, and device rates. Aggregates hospital price transparency data with negotiated contract rates.
How to use it: Visit turquoise.health/patients (opens in new tab). Search by procedure and location. The tool bundles services and fees to match how a medical claim would actually appear on your bill - not just the line-item charges.
Strengths: The most comprehensive aggregation of transparency data. Bundles services realistically. Offers a free verified pricing tool. Founded in 2020, purpose-built for the transparency era.
Limitations: Complex procedures may show incomplete bundling. Best for comparison shopping, not for predicting your exact bill.
What it covers: The federal government's own hospital price lookup, drawing from the machine-readable files hospitals are required to publish.
How to use it: Access via CMS.gov (opens in new tab). CMS provides a Machine Readable File Naming Wizard, TXT File Generator, and Validator tool.
Strengths: Official federal data source. Free. Updated as hospitals publish new files.
Limitations: The raw files are designed for analysts, not patients. Massive spreadsheets with billing codes that require healthcare industry knowledge to interpret. As NPR reported in March 2025 (opens in new tab), "hospital price lists remain largely unhelpful" for consumers.
What it covers: US estimated costs alongside international pricing from China, Thailand, India, and other medical tourism destinations. Hundreds of procedures with price ranges.
How to use it: Visit sylkhealth.com/procedures. Search or browse by procedure. The tool shows US price estimates next to international options, with links to verified providers.
Strengths: The only tool that includes international pricing alongside US data. Useful for patients considering medical tourism who want a side-by-side domestic vs. international comparison. Links directly to verified providers for booking.
Limitations: International pricing is by country and procedure category, not hospital-specific. Best used as a starting point before requesting specific hospital quotes.
Here's a practical workflow for pricing any major procedure:
Step 1: Get your diagnosis code. Ask your doctor for the CPT code(s) for your recommended procedure. This is the standard billing code that all tools use for lookup.
Step 2: Check FAIR Health first. Enter your CPT code and zip code at consumer.fairhealth.org (opens in new tab). This gives you the baseline - what insurance typically pays in your area. Consider this the "fair price" reference point.
Step 3: Cross-reference with Turquoise Health. Search the same procedure at turquoise.health (opens in new tab) to see hospital-specific negotiated rates. If you find rates that are 50-100% above the FAIR Health baseline, you've identified an overpriced facility.
Step 4: Check the international comparison. Search the same procedure on Sylk Health's tool. If the domestic "fair price" is $35,000 and China's price is $10,000 including hospital stay, you know the international option saves 70%.
Step 5: Get a Good Faith Estimate. Under the No Surprises Act (opens in new tab), uninsured and self-pay patients can request a Good Faith Estimate from any provider. The estimate must include all expected charges. If the final bill exceeds the estimate by more than $400, you can initiate a dispute within 120 days (opens in new tab).
Medicare rates are the closest thing the US has to a "real" price for a procedure. They're set by CMS based on actual costs, adjusted for geography and complexity. Everything above the Medicare rate is markup.
The national average hospital markup over Medicare rates is 3.4x (opens in new tab), according to Gerard Anderson's research at Johns Hopkins. The most common markup is 2.4-2.5x. The top 50 hospitals charge up to 10x Medicare rates.

Even with every tool available, domestic price shopping faces structural barriers:
Price variation is extreme. The RAND Corporation's hospital pricing studies document that commercial insurance pays 247% of Medicare rates on average (opens in new tab), with individual hospitals ranging from 150% to 400%+. Moving from a high-cost hospital to a low-cost one in the same city can save 50%. But you can't always choose your hospital - network restrictions, referral requirements, and specialist availability all constrain your options.
Surgery centers vs. hospitals. Ambulatory surgery centers (ASCs) charge 40-60% less (opens in new tab) than hospitals for the same procedures, according to the ASC Association. For procedures like knee arthroscopy, the difference is over 50%. But not every procedure is appropriate for an ASC, and not every market has one.
International pricing breaks the ceiling. Domestic price shopping moves you from a $50,000 hospital to a $25,000 surgery center. International options move you to $8,000-$12,000 - with the hospital stay included. The structural cost advantage of hospitals in China, India, and Thailand isn't just a different insurance negotiation. It's a fundamentally different cost structure: lower real estate, lower administrative overhead, lower labor costs, and government-negotiated equipment pricing.
For a comprehensive look at how US and international prices compare across 20+ procedures, see our surgery cost comparison guide.
For domestic pricing, FAIR Health offers the broadest claims-based database with over 52 billion records. For hospital-specific prices, Turquoise Health provides the most detailed transparency data. For comparing US vs. international pricing, Sylk Health is the only tool that shows both side by side. No single tool covers everything - using 2-3 in combination gives the most complete picture.
Compliance is low. The HHS OIG found 46% noncompliance (opens in new tab) in a 2024 audit. The Patient Rights Advocate found only 21.1% full compliance (opens in new tab) in November 2024. Major systems like HCA Healthcare and UPMC showed 0% compliance. The federal government has penalized just 15 hospitals in four years. NPR reported that even compliant hospitals often publish data in formats that are not useful to consumers (opens in new tab).
Yes. Healthcare Bluebook reports average savings of $1,500 per procedure for patients who use price comparison tools. Ambulatory surgery centers charge 40-60% less (opens in new tab) than hospitals for identical procedures. International options can save 50-80%. The barrier is awareness and access - most patients don't know these tools exist.
Under the No Surprises Act, providers must give uninsured or self-pay patients a written estimate of expected charges before scheduled services. The estimate must include all items and services reasonably expected, including facility fees, surgeon fees, anesthesia, and related services. If the actual bill exceeds the estimate by more than $400, you can initiate dispute resolution within 120 days (opens in new tab).
The national average is 3.4x Medicare rates (opens in new tab), with a range from 1.5x to 10x. CT scans carry a 28.5x markup over actual costs. Prices for the same procedure vary up to 39x within the same metro area (opens in new tab). The variation is not correlated with quality - it reflects market power, not better care.
Every tool listed above is free. The 15 minutes you spend comparing prices could save thousands - or tens of thousands if you include international options.
