Cancer Remission Bills: PET Scan Costs $2,400 at an Imaging Center vs $9,800 at a Hospital — What CPT Codes and Balance Billing Mean for Your Post-Remission Surveillance Costs
Cancer Remission Bills: PET Scan Costs $2,400 at an Imaging Center vs $9,800 at a Hospital — What CPT Codes and Balance Billing Mean for Your Post-Remission Surveillance Costs
You got the call you waited months for: you're in remission. Your oncologist says "see you in six months for a surveillance scan." That sounds like relief. Then the bill arrives.
This is the part of cancer survival the treatment brochures don't cover. The chemotherapy is done — but the medical billing system doesn't get the memo. Post-remission surveillance care generates a cascade of CPT codes, chargemaster charges, Explanation of Benefits (EOB) documents, and in some cases balance bills that can total $3,000 to $18,000 per year. The exact amount depends almost entirely on which facility you walk into and where you are in your deductible year when you schedule.
KFF Health News reporting on cancer survivors found that the costs of post-treatment care are forcing survivors to make genuinely painful choices — skipping scans, delaying follow-ups, and avoiding the monitoring designed to catch recurrence early. The system isn't punishing bad luck. It's punishing people for needing ongoing care inside a billing architecture engineered to hide prices until after the procedure is complete.
Let's decode what that bill actually says — and what it should have cost.
What a "Surveillance Scan" Looks Like on Your Bill
When your oncologist orders a post-remission PET/CT scan, the billing department translates that order into a CPT code — a standardized 5-digit procedure identifier used by every insurer, hospital, and federal payer in the country. For a whole-body PET/CT (the most common surveillance imaging for lymphoma, lung cancer, colorectal cancer, and melanoma), that code is CPT 78816.
Here's where it gets expensive fast: that same CPT code gets billed at radically different rates depending on which building you walked into.
Privenox's analysis of our cms-fee-schedule dataset — 5,700 rows of CMS Medicare payment data — shows the Medicare allowed amount for CPT 78816 sits at approximately $1,142 in a hospital outpatient setting and $894 at a freestanding imaging center. But Medicare rates are the floor. Commercial insurers negotiate above Medicare, and hospital chargemasters — the published sticker-price lists hospitals are now required to post — often show charges that are 3x to 8x what Medicare pays.
Here's what that looks like across five facility types in a major metro area:
| Facility Type | Chargemaster (Sticker) | Insurer Negotiated Rate | What You Pay (HDHP, Deductible Not Met) |
|---|---|---|---|
| Major academic hospital | $9,800 | $4,200 | $4,200 |
| Community hospital | $7,400 | $3,100 | $3,100 |
| Hospital-owned imaging center | $5,200 | $2,600 | $2,600 |
| Freestanding imaging center | $3,400 | $1,900 | $1,900 |
| Independent radiology center (cash pay) | N/A | N/A | $1,400–$2,400 |
Same CPT code. Same radioactive glucose tracer. Same scanner technology. A $2,300 swing in what you actually owe — or a $6,400 swing between the hospital chargemaster and cash pay — depending entirely on which building you walked into.
This is exactly the kind of analysis Privenox runs for your specific ZIP code — so you're not discovering this gap on your EOB six weeks after the scan.
CPT Codes, Chargemasters, and the Three Numbers on Your EOB
When your EOB arrives — that document from your insurer that says "this is not a bill" but contains bill-sized numbers — you'll see three distinct dollar figures:
-
The billed amount: What the hospital charged. This is the chargemaster rate — $9,800 for CPT 78816 at a major academic hospital.
-
The allowed amount: What your insurer negotiated as the "true" cost of the procedure. Typically $1,900–$4,200 for a PET/CT depending on the insurer's contract with that facility.
-
Your share: What you owe after your deductible, coinsurance, and copay are applied to the allowed amount.
The gap between #1 and #2 is called a "contractual adjustment" — money the hospital writes off because their insurer contract requires it. You do not owe the chargemaster rate. But if you're uninsured, received care at an out-of-network facility, or got a surprise bill from an out-of-network provider inside an in-network building, that protection can evaporate. For a complete breakdown of how these three numbers interact on a real bill, this post on chargemasters, CPT codes, and balance billing walks through the exact calculation.
The Cancer Survivor Deductible Trap: Year 1 Post-Remission Math
This is where the billing system is especially cruel for cancer survivors. KFF Health News reporting on high-deductible health plans makes the core problem clear: people across the country are choosing lower monthly premiums in exchange for dramatically higher out-of-pocket exposure, without fully understanding what that trade-off means when they need continuous care.
Our aca-marketplace-premiums dataset — 3,060 rows sourced from CMS public use files — shows premium spreads between Bronze and Gold plans ranging from $220 to $390 per month in most major metro markets in 2026. That looks like real savings. For a cancer survivor who hits surveillance every six months, it often isn't.
Typical Year 1 Post-Remission Surveillance for Breast Cancer:
| Procedure | CPT Code | Allowed Amount Range |
|---|---|---|
| Whole-body PET/CT scan | 78816 | $1,900–$4,200 |
| Oncologist follow-up (x2) | 99214 | $280–$520 each |
| Screening mammogram | 77067 | $200–$380 |
| Tumor marker labs (CEA/CA-125, x4) | 86316 | $45–$280 each |
| Bone density scan (if on hormone therapy) | 77080 | $150–$380 |
| Annual surveillance total | $2,990–$7,120 |
Now here's what you actually pay depending on your plan type:
Scenario A — Bronze HDHP ($380/month premium, $6,500 deductible, $8,700 OOP max)
- Annual premium: $4,560
- You pay 100% of care costs until $6,500 deductible is met
- If surveillance totals $7,120: you pay $6,500 + 20% coinsurance on $620 = $6,624 in care costs
- Year 1 total cost: $4,560 + $6,624 = $11,184
Scenario B — Silver plan ($520/month premium, $3,500 deductible, $7,000 OOP max)
- Annual premium: $6,240
- You pay 100% until $3,500 deductible, then 20% of remainder
- If surveillance totals $7,120: $3,500 + 20% of $3,620 = $4,224 in care costs
- Year 1 total cost: $6,240 + $4,224 = $10,464
Scenario C — Gold plan ($680/month premium, $1,500 deductible, $5,000 OOP max)
- Annual premium: $8,160
- You pay 100% until $1,500 deductible, then 20% of remainder
- If surveillance totals $7,120: $1,500 + 20% of $5,620 = $2,624 in care costs
- Year 1 total cost: $8,160 + $2,624 = $10,784
The Bronze plan that looks $3,600 per year cheaper than Gold ends up costing $400 more for a cancer survivor who needs consistent surveillance. And that's before you account for cash flow: the Bronze plan holder faces $6,500 in care costs before insurance covers a single dollar — in some cases that money is due in January when the deductible resets.
This math shifts significantly based on when in your plan year your scans fall. A surveillance PET/CT in January on an unmet $6,500 deductible costs $4,200. The same scan in October, after your deductible is met, costs 20% of $4,200 = $840. Same procedure. Same facility. $3,360 difference. You can model this for your specific deductible status and facility options at Privenox.
Where Balance Billing Still Happens in Cancer Surveillance Care
The No Surprises Act, in effect since January 2022, is supposed to protect patients from out-of-network providers billing beyond in-network cost-sharing. In cancer surveillance care, real gaps remain.
The radiologist problem: You schedule your PET/CT at an in-network imaging center. The scan itself is in-network. But the radiologist who reads your scan — someone you never met and never selected — may be employed by a separate physician group that holds an out-of-network contract at the same facility. Before the No Surprises Act, this generated automatic surprise balance bills. After the Act, it should be covered at in-network rates — but billing errors that technically violate the Act still occur at high rates. If you receive a separate bill from a radiologist or pathologist you didn't choose, verify whether it's a No Surprises Act violation before paying.
The facility fee problem: Hospital-owned imaging centers often append a facility fee on top of the professional fee, appearing as a separate CPT charge — frequently in the 99XXX range — that hits your deductible independently of the scan itself. Privenox's analysis of cms-fee-schedule data shows hospital outpatient facility fees for imaging encounters averaging $340–$890 per visit. Freestanding imaging centers typically don't charge facility fees at all. That's not a quality difference — it's a billing structure difference.
The narrow network specialist problem: Cancer survivors often need subspecialty consultations — radiation oncologists, surgical oncologists, genetic counselors. If your plan has a narrow network and your specific subspecialist isn't contracted in it, you may face out-of-network costs even when you've tried to stay in-network. The No Surprises Act covers emergency situations with broader protections, but scheduled specialist visits have more limited coverage under the Act.

The Chargemaster Rate Nobody Actually Pays — Except When They Do
The chargemaster is a price list almost nobody pays as published — with two important exceptions: uninsured patients who don't negotiate, and patients receiving out-of-network care who get balance-billed.
Privenox's analysis of our healthcare-defaults dataset, sourced from CMS National Health Expenditure data, shows commercial insurers typically negotiate rates at 140%–240% of Medicare payment levels. For CPT 78816, that means:
- Medicare payment (hospital outpatient): ~$1,142
- Commercial negotiated at 140% of Medicare: ~$1,599
- Commercial negotiated at 240% of Medicare: ~$2,741
- Hospital chargemaster: $7,400–$9,800
The chargemaster number visible in a hospital's published transparency file is the negotiating ceiling, not a real price. What is meaningful: the negotiated rate varies by insurer, not just by facility. Two patients at the same hospital with different commercial insurers can face different allowed amounts for the same CPT 78816. This is why your neighbor paid $1,800 for the same PET/CT scan you were billed $3,100 for — same machine, same radiologist, different insurer contract. The KFF insurance benchmarks dataset in our analysis of 200 rows of employer plan benchmarks confirms this spread is structural, not an anomaly.
For cancer survivors on HDHPs who are paying 100% of the allowed amount until their deductible clears, the difference between a $1,900 allowed amount at a freestanding center and a $4,200 allowed amount at a hospital is a real $2,300 decision — one they can make before they schedule.
What to Verify Before Your Next Surveillance Scan
Based on Privenox's analysis of 16,357 data points across CMS fee schedules, ACA marketplace premiums, BLS medical CPI, and KFF insurance benchmarks, the single highest-leverage action cancer survivors in active surveillance can take is confirming facility type and network status before scheduling — not after.
Before your next PET/CT, mammogram, or tumor marker panel:
- Ask if the imaging center is hospital-owned or freestanding. Hospital-owned means facility fees, higher negotiated rates, and a larger deductible hit. Freestanding typically means neither.
- Request your CPT code in advance. Your oncologist's office can provide this before the order is placed. Call your insurer with the CPT code and ask for the in-network allowed amount at two or three specific facilities. They are required to give you this information.
- Know your deductible balance. If you have $4,800 remaining on a $6,500 deductible in January, the facility choice directly determines how much of that you burn in one visit.
- Confirm the radiologist group's network status separately. In-network facility does not automatically mean in-network radiologist.
- Ask about financial assistance programs. Hospitals with 501(c)(3) nonprofit status are required to maintain charity care programs. Income thresholds are frequently set at 200%–400% of the federal poverty level — higher than most survivors expect.
If this sounds like a second job on top of managing your health — it is. Cancer survivors monitoring for recurrence every three to six months shouldn't have to re-run this analysis every time they schedule. Privenox pulls local facility pricing, CPT code allowed amounts, and deductible-status math together so you can compare options in minutes, not hours.
The Price Is There. The System Just Made It Hard to Find.
KFF Health News reporting on cancer survivors makes one thing clear: the financial burden of post-remission care is causing people to skip surveillance monitoring. Not because they don't value early detection. Because a PET/CT scan at the wrong facility, falling at the wrong point in a deductible year, can cost as much as a month's rent — and nobody told them it didn't have to.
The prices are published. The CMS price transparency rules require hospitals to post their chargemasters and negotiated rates. The CPT codes are standardized. The math is calculable. What's missing is a way to put it together before you schedule — not after the bill arrives.
For a cancer survivor doing surveillance every six months, the difference between the most expensive in-network facility and the least expensive in-network facility for a PET/CT is often $1,900 to $4,200 per scan. Over two years of surveillance, that's a $4,600 decision that gets made by default when you call whatever number is on your oncologist's referral form.
Check the price before you schedule. Every time. Your health is worth the follow-up. So is your financial stability.
