Pay cash or use insurance for an outpatient procedure? How to compare the two prices

Two routes, two different prices for the same code

The cash route is a price the facility sets for a patient who pays directly. The insured route is not a facility price at all. It is your share of the amount your plan allows for the service, after your plan's cost-sharing rules are applied. Comparing a cash quote with a facility list price, or with the total billed charge on an insured claim, compares the wrong numbers. The comparison that matters is the cash all-in total against your own insured share.

Question	Cash route	Insured route
What is the price based on?	The all-in cash price the facility states for the exact CPT code and setting	The allowed amount for that code under your plan, which is the maximum amount a plan will pay for a covered service, then your cost-sharing rules
What written document proves it before service?	A written cash quote, or a Good Faith Estimate if you are self-pay for the service	A written plan or facility estimate that states the deductible and cost-sharing figures it used
What decides your share?	The quote itself, layer by layer	How much deductible you have left, then a copayment or coinsurance, capped by your out-of-pocket maximum
Does the payment move you toward your deductible or out-of-pocket maximum?	Ask the plan in writing. Do not assume a payment made with no claim submitted is credited.	Cost sharing on a submitted, covered claim is the amount the plan tracks toward those totals.
What happens if the plan changes on the day?	The changed code needs its own cash price, confirmed in writing	The changed code is processed under its own allowed amount and the same cost-sharing rules
What protection applies if the bill is higher?	For self-pay care, the federal patient-provider dispute process when one provider bills at least $400 more than its Good Faith Estimate	The plan's own claim and appeal process, checked against the explanation of benefits

The allowed amount wording follows the HealthCare.gov glossary definition used across federal coverage materials: the allowed amount is the maximum amount a plan will pay for a covered health care service, and it may also be called the eligible expense, payment allowance, or negotiated rate. Your plan's figure for your code is a plan fact, not a figure this site can publish for you. Ask the plan for it, or ask the facility billing office what allowed amount its insured estimate is built on.

The four plan numbers you need before any insured estimate means anything

HealthCare.gov explains total health care costs as the premium plus what you pay when you get care: the deductible, copayments and coinsurance, and the out-of-pocket maximum. For a single scheduled procedure, the premium is already being paid either way. The four numbers below are the ones that move your insured share for this service. Get each one for your plan, for this date, from your plan's member portal, your plan's cost estimator, or a call to the number on your card. Write down who gave you each figure and when.

Plan number	What it means	Why it changes this comparison
Deductible remaining	The deductible is how much you spend for certain covered services before your plan pays anything, apart from free preventive services. The remaining amount is the part you have not met yet this plan year.	If the allowed amount fits inside your remaining deductible, your insured share can be the full allowed amount. In that case the insured route and the cash route are both paid by you, and the totals, not the labels, decide.
Copayment or coinsurance for this service	A copayment is a fixed amount you pay each time you get care, such as a set amount for a visit. Coinsurance is your percent share, such as 30 percent of hospital charges in the HealthCare.gov example.	After the deductible, this is the rule that splits the rest of the allowed amount between you and the plan. Ask which one applies to this CPT code in this setting. Some services use one, some the other, and some are covered before the deductible under plan rules you need stated.
Allowed amount for the exact code	The plan maximum payment for the covered service, before your cost sharing is taken out of it.	Your share is a share of the allowed amount, not a share of the facility billed charge. An insured estimate that does not state the allowed amount behind it cannot be checked.
Out-of-pocket maximum remaining	The out-of-pocket maximum is the most you spend for covered services in a year. After you reach it, the insurance company pays 100 percent for covered services.	If you are close to the maximum, or have reached it, the insured share for later covered care falls, and can fall to zero for covered services. If you are far from it and expect little other care, that future value may matter less for this one decision. Both are plan facts to state, not assumptions.

Two warnings belong with those four numbers. First, they change during the year as other claims are processed, so a figure from January does not describe a booking in October. Use figures dated close to the day you book. Second, family coverage can carry more than one deductible and more than one maximum. Ask which deductible applies to you for this service: an individual amount, a family amount, or both in sequence under your plan's rules.

Step 1: Fix the code and the setting first

Both prices must describe the same service, or the comparison is already broken. Get the CPT code from the ordering clinician's office and note whether an add-on is expected on the day, such as contrast, tomosynthesis, a biopsy, or additional views. The procedure pages on this site list the code variants for each of the 30 procedures, and How to find a procedure price by CPT code walks through starting from the code itself. Then fix the setting in the same sentence: hospital outpatient department, ambulatory surgery center, independent imaging center, or physician office. Setting changes both routes at once. A hospital cash quote and an imaging center insured estimate are not a comparison of routes. They are a comparison of places.

Step 2: Get the cash total, layer by layer

Use the exact ask from How to ask for the cash price: "What is the all-in cash price for CPT [code] performed in [setting], including the professional fee, the facility fee, anesthesia, and pathology if they apply? Please list what is included and what would bill separately." Write down each layer separately, even when the answer is that a layer is included. For imaging, the layers are usually the facility or technical layer and the professional reading layer. For endoscopy and surgery, anesthesia and pathology can add their own layers, each billed by a different group.

If you think you may take the cash route, say so in the terms the federal rules use. CMS describes the Good Faith Estimate right as applying when you do not have insurance or do not use insurance for the service. Ask for the written cash figure as a Good Faith Estimate, with each provider or facility that expects to bill listed on its own estimate. That document is what the Good Faith Estimate Checker compares against a later bill, and it is what gives the $400 dispute rule in Good Faith Estimates and the No Surprises Act something to attach to. A verbal cash discount with no estimate behind it carries neither.

Step 3: Get the insured total the same way

Ask your plan, through its cost estimator or member line, for your estimated share for the exact CPT code, at the named facility, in the named setting, on a date close to your booking. Then ask the facility billing office the matching question, because the facility is the party that will bill the claim. A complete insured estimate states five things:

1. The CPT code and setting it priced.
2. The allowed amount it assumed for each layer.
3. Your deductible remaining on the date of the estimate, and how much of this service would go toward it.
4. The copayment or coinsurance that applies after the deductible, for each layer.
5. Whether the facility and each group that will bill are in network for your specific plan.

If an estimator gives you one total with none of those figures behind it, treat it the way this site treats a cash quote with no code: as a starting point for questions, not as a confirmed price. Ask for the figures. The Price-Check Resources directory lists the official cost estimator and transparency tools published by CMS, state programs, and major insurers, with who runs each tool and when it was verified.

Step 4: Ask the deductible credit question in writing

This is the step people skip, and it can quietly reverse the answer. A cash total that is lower today can still be the more expensive choice over the plan year if none of it is credited toward a deductible you will meet anyway with other care, while the insured payment would have moved you that much closer to the point where the plan starts sharing costs, and then to your out-of-pocket maximum.

The federal definition explains why the question has to be asked, not assumed. For Good Faith Estimate purposes, CMS defines a self-pay individual as a person who is enrolled in a plan but is not seeking to have a claim submitted to that plan for the item or service. No claim submitted means the plan has no claim in front of it to credit in the ordinary way. Plans differ in whether and how they credit a payment made outside a claim, what documentation they require, and whether there is a deadline to submit it. So ask both parties, in writing, before service:

• To the plan: "If I pay the facility directly for CPT [code] and no claim is submitted, will any part of that payment count toward my deductible or my out-of-pocket maximum? If so, what form and what proof of payment do you require, and by when?"
• To the facility: "If I pay cash for this service, will you submit a claim to my plan as well? If I later ask you to submit one, can you, and would the cash price still apply?"

Keep the answers with both price quotes. If the plan will not credit the cash payment, write "no deductible credit" as its own row in the comparison table below. That row has a dollar meaning only in the context of your other expected care, which is the next step.

Step 5: Fill in one table, both routes, same layers

Put both totals into the Procedure Quote Worksheet, one column per route, and use the rows below. The worksheet holds the quotes you obtained yourself and lines them up against the Medicare anchor from your procedure page. Your entries stay in your browser.

Row	Cash route	Insured route
Facility or technical layer	Cash amount stated, or included	Your share of the allowed amount for that layer
Professional layer	Cash amount stated, included, or billed separately by whom	Your share for that group, and its network status
Anesthesia and pathology, if they apply	Cash amount stated, likely, or billed separately	Your share for each group, and each network status
Day-of-change code	Cash price for the changed code, in writing	How the changed code would be processed
Total you pay for this service	All-in cash total	Your total share across every layer
Deductible and out-of-pocket credit	Plan answer in writing: credited, not credited, or credited only with a submitted claim	Amount of the total that counts toward the deductible, and then toward the maximum
Written document you hold	Written quote or Good Faith Estimate, with date and validity	Written plan or facility estimate, with the figures behind it and the date

Read the table in two passes. The first pass is today: which total is lower for this service, all layers counted. The second pass is the plan year: what does each route do to your deductible and your out-of-pocket maximum, and what other covered care do you already expect this year that those totals would affect? A route that is slightly higher today and finishes your deductible can be the lower cost route by December. A route that is lower today and earns no credit can be the higher cost route the next time you need care. Neither pass alone is the answer.

A worked comparison with the anchors already on this site

Start with a real anchor, then keep the invented figures clearly separate from it. For brain MRI without contrast, CPT 70551, this site publishes a verified Medicare Physician Fee Schedule global anchor of $192.65, made up of a $69.04 professional component and a $123.61 technical component, for Michigan Locality 01 in CY2026, verified 2026-10-18. In a hospital outpatient department, the verified Medicare OPPS facility anchor for the MRI without contrast composite, APC 8007, is $537.85, with the professional fee billed on top of it. Those anchors, from the MRI without contrast procedure page, tell you the structure and the order of magnitude. They are not a cash price and they are not your plan's allowed amount.

Now the illustration. This example is hypothetical. Every dollar figure in this paragraph and the next is invented to show the arithmetic, and none of it is a price, an average, or a quote for any real facility or plan. Suppose an imaging center states an all-in cash price of $450 for CPT 70551, global, in writing. Suppose your plan's allowed amount for the same code at the same center is $600, you have $500 of deductible still unmet, and your coinsurance after the deductible is 20 percent. On the insured route you would pay the first $500 toward the deductible, then 20 percent of the remaining $100, which is $20, for a total insured share of $520 for this service, with your deductible then met. In this invented example the cash total, $450, is $70 lower today, and the insured total, $520, finishes the deductible. Which route is better depends on the care you expect next, which is exactly why both rows belong in the table.

Change one invented fact and the arithmetic flips. Still hypothetical: suppose you had already met your deductible before this booking, with the same invented allowed amount of $600 and the same 20 percent coinsurance. Your insured share would be 20 percent of $600, which is $120, well below the invented $450 cash total. Suppose instead you had already reached your out-of-pocket maximum for covered services. HealthCare.gov states that after you reach that maximum, the insurance company pays 100 percent for covered services, so your insured share for a covered service would be zero in that situation, subject to confirming the service is covered and the maximum is in fact met. Run your own figures through the Price Anchor Explorer for the anchor side and the worksheet for the quote side, using the real numbers your facility and your plan give you.

Three situations the table usually settles

Your deductible is large, unmet, and you expect little other care

If the allowed amount sits inside a deductible you do not expect to meet this year, the insured route can leave you paying the full allowed amount while the cash route asks for the facility's own cash total. Compare those two totals directly, layer by layer. The remaining question is the credit row: paying the allowed amount through a claim moves the deductible, paying cash may not. If you truly expect no other care that the credit would help with, state that as your reason in your notes, rather than leaving it unexamined.

You expect more covered care this year

If other scheduled or likely covered care will take you through the deductible anyway, the credit row gains weight. An insured payment today is also progress toward the cost-sharing stages that follow, and then toward the out-of-pocket maximum. Price the year, not only the appointment: add this service's insured share to the share you expect from the later care under each route, and compare those two year totals with the cash total for this service plus the insured shares for the later care with no credit from today.

The service may be covered before the deductible, or at a copayment

HealthCare.gov notes that the deductible describes what you spend for certain covered services before the plan pays anything, except free preventive services. Plan rules, not guesses, decide whether a given service is subject to the deductible, covered before it, or priced at a fixed copayment. Ask the plan which treatment applies to your exact code. A screening service and a diagnostic service with a similar name can be priced under different rules, and the code is what separates them. The procedure pages list those code pairs, for example screening mammogram CPT 77067 and diagnostic mammogram CPT 77066, so you can ask about the right one.

What each route does not do

• The cash route does not use your plan's network protections. Network status, balance billing protections for certain care at in-network facilities, and the plan's claim process belong to the insured route. If any group that will bill is out of network, that fact belongs in the insured column before you compare totals.
• The insured route does not give you a Good Faith Estimate under the federal self-pay rule, and the $400 patient-provider dispute process in the Good Faith Estimates guide is built for a bill measured against such an estimate. On the insured route, your after-service check is the explanation of benefits against the itemized bill, using How to check an itemized bill for errors.
• Neither route freezes a day-of-change code. If a diagnostic procedure becomes a biopsy procedure, or a without-contrast study becomes a with-contrast study, the new code carries its own price on both routes. Get the changed-code figure in writing in advance, on the route you choose.
• Neither route on this page covers emergency care. Do not delay emergency care to run this comparison. CMS notes that Good Faith Estimates are not given during emergency care, and emergency cost-sharing protections follow different rules, covered in Urgent care vs ER: where to go and what it costs.

Common mistakes in this comparison

• Comparing the cash total with the facility billed charge on an insured claim, instead of with your own share of the allowed amount.
• Asking for an insured estimate without stating how much deductible is left, so the estimate quietly assumes a met deductible you have not met.
• Assuming a cash payment counts toward the deductible without asking the plan, in writing, whether a payment with no claim submitted is credited.
• Comparing a cash price from one setting with an insured estimate from another setting, and calling the difference a route difference.
• Counting only the facility layer and forgetting the professional, anesthesia, or pathology groups that bill separately on either route.
• Deciding before asking for the cash figure as a Good Faith Estimate, then discovering after the bill that the $400 dispute rule has no estimate to measure against.

Each mistake is fixed by the same discipline used across this playbook: exact code, exact setting, every layer named, both totals in writing. Our methodology explains why this site publishes the verified Medicare anchor and this comparison method instead of inventing a typical cash price or a typical insured share to fill the gap. There is no typical share. There is your plan, your deductible, and the two written totals for your code.
