Before you book: three questions that change the price
- Is this the self-pay price, and does it include the doctor, anesthesia and any lab or pathology? Those are often billed separately.
- Can you give me the price in writing, with the billing codes it covers?
- What happens to the price if something extra is needed during the procedure?

Quick take
- Ask for the cash price if your deductible isn't met - the median cash price here is $51, and it's often lower than what insurance pays before your deductible is satisfied.
- Ask whether this procedure can be done at a freestanding ambulatory surgical center - they're typically 30-60% cheaper than a hospital for identical care, and most aren't in this hospital-only dataset.
How much does an X-ray cost with Medicare in Napa, CA?
Medicare's national hospital outpatient payment for X-ray is about $89 to $107 (typically near $89). After the $257 Part B deductible, you generally pay 20% of the Medicare-approved amount, about $18 on a $89 payment, with no out-of-pocket cap unless you have supplemental coverage or a Medicare Advantage plan.
Doctor, anesthesia and pathology fees are billed separately. Medicare rates are national CMS amounts, adjusted slightly by local wage levels.
California has the most competitive commercial hospital market in the country, with aggressive multi-system competition in every major metro driving meaningful price variation. Kaiser Permanente's integrated payer-provider model covers roughly 40% of the insured population in the state - if you're Kaiser-enrolled, the prices here largely don't apply. California's robust price transparency enforcement under SB 1204 means the data here is more complete than in most states. X-ray is the most commoditized of all imaging procedures, and price differences are almost entirely explained by facility type: a hospital outpatient chest X-ray can cost 5–10× more than the same study at an urgent care center or independent imaging clinic. For non-emergency X-rays, asking your physician for a referral to an outpatient imaging center rather than a hospital radiology department is the simplest and most reliable cost reduction available.

Why prices vary - and what it means for your coverage
Facility classification matters as much as the hospital itself - a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Whether the scan happens in a hospital outpatient department (which adds a separate facility fee) or a freestanding imaging center is usually the single biggest driver of price for this procedure.
None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$51 |
| Deductible met - 20% coinsurance | ~$10 |
| Out-of-network provider | $112+ |

Asking for the cash price as well as your insurer's negotiated rate is often the single biggest lever on what you pay.
How much will I actually pay out of pocket for an X-ray in Napa, CA?
Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price.
