Blood test, clotting time (PT/INR) cost in CA

What a blood test, clotting time (pt/inr) costs at CA hospitals — and the fair price to aim for.

Pillar 1 · The BaseRate™ CompositeHow 1.00× Fair BaseRate Works: Raw price averages unfairly penalize hospitals in high-wage cities or trauma centers treating sicker patients. We adjust for local CMS hospital wage levels and patient complexity first. A 1.00× score means right at the fair price average, 0.85× means 15% cheaper than fair market, and 1.30× means 30% above fair market.Near Fair BaseRate Benchmark
1.00×vs. Fair Market Price
Position vs. 1.00× Fair PriceRight at U.S. Average (0%) 1.00× (center of the bar) is the U.S. fair price average after accounting for local hospital wages and patient complexity. Left of center (<1.00×) is below fair price; right of center (>1.00×) is above fair price.

Typical commercial prices here match the fair market benchmark (1.00×) after accounting for local nurse/doctor wages and patient complexity.

Pillar 2 · VeriRate™ Data TrustHow VeriRate™ (0–100) Works: Hospitals are legally required to publish machine-readable price files, but some bury fake $0.01 numbers or omit cash discounts. VeriRate audits each file across 5 checks (hover any badge below to see what it tests).86/100 · Verified
86/100Hover Any Check Below to See How Prices Were Audited
File Completeness90Provenance (File Completeness): Checks whether the hospital published a complete, up-to-date machine-readable price file with valid CPT and MS-DRG billing codes instead of leaving blanks.
Price Logic88Coherence (Price Logic): Checks whether the hospital’s numbers make basic sense — e.g., self-pay cash price is lower than gross list price, with no fake $0.01 or $999,999 placeholder numbers.
Peer Alignment86Concordance (Peer Alignment): Checks whether reported prices sit in a realistic range compared to Medicare and nearby hospitals rather than wild 100× unit errors.
Clean Billing83Regularity (Clean Billing): Checks whether rates are structured consistently across procedures without erratic statistical spikes or hidden unbundled facility fees.
Real Cash Discount84Cash Honesty (Real Cash Discount): Checks whether the hospital offers a genuine self-pay cash discount that beats or matches commercial insurance rates instead of billing full sticker price.
Pillar 3 · Clinical Quality & ER SpeedChecks whether higher hospital prices actually buy better clinical quality — combining CMS Star Ratings, hospital safety scores, and emergency room wait times.Regional Value Leader
CMS Star RatingNot RatedOfficial CMS Overall Hospital Quality Star Rating (1 to 5 stars) summarizing mortality, safety of care, readmissions, and patient experience.
Safety ScoreNot ScoredComposite patient safety score (0–100) derived from CMS hospital-acquired infection rates (CLABSI, CAUTI, MRSA, C. diff), surgical complications, and HCAHPS surveys.
Typical ER WaitNo ER DataMedian minutes patients spent in the emergency department before leaving from the visit, as reported to CMS Timely and Effective Care.

Balances commercial hospital prices against CMS clinical safety, infection control, and patient experience.

Where You Can Get Burned (Markup Traps)

  • Even at low-cost facilities (1.00× Fair BaseRate), out-of-network or unnegotiated chargemaster bills can exceed commercial medians — confirm in-network status or request a self-pay cash quote up front.
  • Commercial insurance median sits at 0.62× Fair BaseRate (0.7× Medicare), so insured patients should always compare the self-pay cash price before paying.
  • Even at low-cost facilities (1.00× Fair BaseRate), out-of-network or unnegotiated chargemaster bills can exceed commercial medians — confirm in-network status or request a self-pay cash quote up front.
  • Unnegotiated chargemaster list prices average 4.1× Medicare (26¢ true HCRIS cost per $1 gross)
