Are We Really Fee-for-Service? The O&P Payment Illusion
If you listen to CMS and most commercial payers, prosthetics and orthotics live in a clean, old-school fee-for-service world. We bill HCPCS codes, there’s a fee schedule, and we get paid per device. Simple, right?
Out in the real world, it doesn’t feel simple at all. When you look closely at how risk, work, and money actually move from intake to delivery, O&P already functions a lot more like a bundled, episode-based service than a pure “provide a service, bill a code” model. The gap between the official story and your day-to-day reality is what I call the fee-for-service illusion.
Let’s look at how that illusion works and why it matters before anyone gets too excited about layering value based care on top of it.
What CMS Says: Classic Fee-for-Service
On paper, O&P is straightforward.
Medicare pays for DMEPOS using a fee schedule. Each HCPCS code has an allowed amount; Medicare pays 80% of the lower of your charge or the fee schedule rate, and the patient (or secondary) is responsible for the remaining 20% plus any deductible. CMS publishes and updates those fee schedules regularly, with adjustments for new codes, policy changes, and inflation.
That’s the official story: you provide a discrete service, you submit the claim, and you’re paid per code. Fee-for-service.
But that frame leaves out almost everything that actually drives your risk and workload.
Where the “Episode” Sneaks In
Start with a simple question: when do you actually get paid?
You only get paid when all the conditions of coverage line up—valid order, documented medical necessity (from a third party), correct coding, proof of delivery, and the beneficiary meets benefit requirements. That’s not a single transaction; it’s a chain of events from referral through delivery. If any link fails, you don’t just lose one visit; you lose the whole episode’s revenue.
Then look at what that one L-code payment is expected to cover. For most prosthetic and orthotic devices under Part B, the fee for the device is implicitly expected to pay for:
Evaluation and history review
Casting or scanning
Design and fabrication coordination
Fitting and delivery
Adjustments
Initial training and education
A fair amount of routine follow-up and adjustment
Those touches are not separately reimbursed to you. The “fee-for-service” is effectively a mini bundle wrapped around an episode of care. You’re managing time, materials, and clinical risk within a fixed revenue ceiling—just like a formal bundled payment, just without the name.
Site of Service: When Your Work Is Literally in Someone Else’s Bundle
The illusion gets even stronger when you look at what happens in other facilities.
Under Medicare’s consolidated billing rules for skilled nursing facilities (SNFs), most services and supplies are included in the Part A perdiem the facility receives. Many orthotic devices used during a covered SNF stay are bundled into that facility’s payment; you don’t get to bill Part B directly for them the way you would in the community. Some customized prosthetics are treated differently, but the pattern is clear: in certain settings, your work is already “inside the bundle.”[cms]
At the same time, CMS has built formal bundled payment models (like BPCI) where they keep paying providers fee-for-service on the surface, then reconcile total episode spending against a target price in the background. Hospitals, physician groups, and conveners agree to be accountable for all costs in a defined episode, and they get bonuses or penalties based on how actual spending compares to the target.
If you provide O&P care to a patient in one of those episodes, your “fee-for-service” claim is just one piece of someone else’s bundle. They are watching your cost and your impact on readmissions, post-acute use, and complications, whether they ever say the word “bundle” to you or not.
Medicare Advantage: Bundling by Another Name
Medicare Advantage plans pile on another layer.
They start from the same DMEPOS fee schedule, but then add prior authorization, frequency limits, site-of-service rules, and narrow networks. In practice, that means:
They try to control how often they pay for certain devices over a multiyear window.
They steer patients toward lower cost options and in network suppliers.
They may treat combinations of codes (e.g., test socket plus definitive device) as inclusive or mutually exclusive—even when the fee schedule itself doesn’t say that.
None of that looks like classic “I do a service, you pay me for the service.” It looks like a payer managing a budget for an episode of care and deciding how much of that budget they’re willing to allocate to O&P over time.
The Evidence: O&P Is Already an Episode Player
The strongest O&P outcomes data we have actually reinforces this episode view.
The Dobson–DaVanzo analyses found that Medicare beneficiaries who received appropriate orthotic and prosthetic services had similar or lower total 15–18 month episode payments compared with matched patients who didn’t receive O&P care—even though the devices themselves can be expensive. Savings showed up in fewer or shorter facility-based stays and different patterns of post-acute care, not in cheaper devices.
Put differently: your work changes the shape of the entire episode, not just the cost of one line item. That’s exactly how bundled and value-based models think about the world.
Why This Illusion Matters
If you still believe you’re working in a true fee-for-service environment, you’ll make the wrong strategic choices.
You’ll focus your conversations with payers and health systems on Lcodes and unit prices instead of total episode cost and avoided utilization (costs to the payer).
You’ll be blindsided when formal value-based care pilots arrive and everyone else in the system says, “We’ve been thinking in episodes for years—why haven’t you?”
CMS has already told us where they’re headed: value-based care that focuses on quality, provider performance, and the patient experience, using models that integrate providers around the total needs of a person across time. Bundled payments like BPCI explicitly combine physician, hospital, and other services into one accountable episode, even if fee-for-service billing continues in the background.
O&P is officially labeled as fee-for-service. Functionally, you are already living inside those episodes—you just don’t get to hold the contract.
So, Are We Really Fee-for-Service?
Technically, yes: you bill HCPCS codes against a DMEPOS fee schedule and get paid per claim. Practically, no: your revenue for a device has to fund an entire episode of care, and in some settings, your work is literally bundled into someone else’s payment.
Understanding that disconnect is the first step to making smarter decisions. It changes how you think about:
Intake and scheduling (you’re managing an episode, not a visit).
Documentation (you’re supporting a narrative for the whole episode, not just a claim).
Conversations with payers and health systems (you’re selling episode value, not unit price).
Once you see the fee-for-service illusion clearly, the next logical question is: what happens when formal value-based care models show up on top of this already bundled reality? That’s where the “Value Based Care Trap” begins—and we’ll tackle that in the next blogs.
