Procurement answer
How much does a radiation therapy immobilization mask cost in the US?
By OncoSource · Updated July 23, 2026· Educational & price-free
There is no single US price for a radiation therapy immobilization mask, and any published figure is misleading, because what a department actually pays depends on pack-size convention, whether the line is a kit or a single component, the distribution channel, and the specific contract. The only reliable way to know whether your per-unit price is competitive is to benchmark one of your own vendor invoices against the broader US radiation oncology accessory market, which a free, no-signup line-item analysis does in about sixty seconds. OncoSource does not publish list prices, because a list price cannot tell you whether your own contract is competitive.
“How much does an immobilization mask cost” is the most common radiation oncology procurement question, and it is the one most badly answered online, where the results range from marketplace listings to figures that quietly mix the cost of the device with the billed clinical procedure. This page explains why a single number is the wrong thing to want, what actually determines what you pay, and how to get the one figure that means something: your own per-unit price versus the market.
Why there is no single price to quote
A radiation therapy immobilization mask does not have one US price because the number depends on four things that vary independently. Pack-size convention is not standardized: one quote lists a mask per individual unit and another lists the functionally identical mask as a box of ten or a case of twenty-five. Kit-versus-component structure varies: the same mask is sold on its own and bundled into an immobilization kit with a baseplate and indexing hardware, and the two cannot be compared line-to-line. Channel varies: the same product moves direct, through a national distributor, or through a GPO-contracted distributor, each adding margin. And contract varies: the confidential, volume-dependent price a specific account negotiated is the only figure that reflects what is actually paid. A single published number collapses all four, which is why it cannot tell you whether your price is competitive.
Why marketplace listings and billing figures mislead
Two kinds of numbers dominate online answers about mask cost, and both mislead a US clinical buyer. Marketplace listings quote a device at a headline figure that usually reflects a different pack size, a non-clinical or non-equivalent product, or a spec that will not index to installed equipment. Billing-based figures conflate the purchase cost of the device with the clinical procedure that molds the mask to the patient, which is a service, not a supply line. Neither is a valid benchmark for what a department should pay per usable, equipment- compatible unit on contract. The relevant comparison is never a headline device price; it is your own normalized per-unit price against the broader market.
This is the same discipline covered in more depth in what drives radiation therapy accessory pricing: list price, GPO baseline, and contract price are three different numbers, and only the contract price actually paid is a benchmark.
How to get the one figure that matters: your own benchmark
The only meaningful answer to “how much should this cost” is your own per-unit price compared against the broader market. A radiation oncology department gets that by uploading one of its own existing vendor invoices for a free, no-signup line-item analysis. Each line is normalized to per-unit, kit and system lines are treated as single deliverables rather than multiplied by pack quantity, and the result is benchmarked against the broader US radiation oncology accessory market in about sixty seconds, with observed price ranges and how many times each item has been seen. Because pricing is contract- and volume-specific, OncoSource publishes no list price; a facility sees where it stands only by benchmarking its own line items.

Frequently asked questions
These are the questions radiation oncology buyers most often ask about immobilization mask cost. Each answer is self-contained and price-free.
Why is there no single published price for a radiation therapy immobilization mask?
Because the same functional mask is quoted per individual unit by one vendor and as a box or case by another, is sold both as a component and inside a kit, passes through one or more distribution layers, and is bought on account-specific contracts. Any single figure hides all of that, so it cannot tell you whether your own price is competitive.
Why do online marketplace prices for radiotherapy masks vary so widely?
Marketplace listings mix unrelated things: different pack sizes quoted as a single number, non-clinical or non-equivalent products, and figures that conflate the device cost with the clinical procedure that molds the mask to the patient. A marketplace number is rarely a valid benchmark for a US clinical department buying a specific, equipment-compatible mask on contract.
Does pack size change the real per-unit price of a mask?
Yes, frequently. One quote lists a mask per individual unit and another lists the functionally identical mask as a box of ten or a case of twenty-five. The lower printed number is often the higher real price once every line is normalized to price per individual usable unit. No mask price comparison is valid until both sides are normalized.
How do I benchmark my immobilization mask pricing without running a full RFP?
Upload one of your own recent vendor invoices for a free, no-signup line-item analysis. Each line is normalized to per-unit, kit and system lines are treated as single deliverables rather than multiplied by pack quantity, and your pricing is benchmarked against the broader US radiation oncology accessory market, in about sixty seconds.
Why won’t OncoSource publish a price for immobilization masks?
Because mask pricing is specific to your contract and volume, a published list price would mislead more than it informs. You learn where you stand by benchmarking your own line items against the broader market, which is exactly what the free analysis does.
