I started interacting with the people I had dreamed for so long of helping. In the quiet moments at the research lab, as the patients and their families filled out consent forms, they presented me with questions not only about the prosthetic arms, but about living a life that requires a prosthetic arm. Can we take this one home? How much will it cost? What do I do if my insurance doesnt cover arms anymore? How am I supposed to keep a job?
Initially, I didnt know the answers. Then I did. But I didnt know how to tell patients the truth: The American medical system makes no real accommodations for the vast majority of amputees. Prosthetic arms and legs, unless they are truly rudimentary, typically cost more than $60,000. They require replacement parts every year that can cost thousands more, and only a small fraction of the cost of limbs and spare parts is covered by insurance.
Last fall, a prosthetics industry innovator named Alan Hutchison rekindled an old debate by posing this question on LinkedIn: Why should you pay more for a prosthetic with a microprocessor knee than for a new average family sedan car? Whats the logic of this, given that the technologies in the feet and knees are similar to those for leaf springs and power liftgates [that represent] a fraction of a cars total cost?
To put hard numbers to this: The average new family sedan (e.g., a Chevy Malibu) retails for about $30,000. The average prosthetic leg equipped with a microprocessor knee (e.g., an Ottobock C-Leg) will cost you and/or your insurer about twice that amount.
How can the reimbursement systems justify paying so much? asked Hutchison, cofounder and CEO of the distributed-care startup ProsFit. If the per-unit cost were lower, couldnt you sell far more devices, improve far more amputees lives, and generate equal or greater profits?
The comments section erupted. Car prices are less outrageous because demand is so much greater, went one popular argument; if prosthesis ownership was as universal as car ownership, prices would fall. A second argument: Cars are mere conveniences, whereas limbs equipped with microprocessor knees (MPKs) are life-changing amenities and therefore infinitely more valuable. Several people observed that the price tag for a prosthesis covers not only the hardware but also several years worth of the clinicians limb-care expertise. If prosthetists were paid for their clinical care and not for devices delivered, the cost would come down, noted one commenter. Another added: A car dealer sells inventory, produced at scale and force-fed to the market. The prosthetist provides custom solutions to meet a very specific set of functional and clinical needs.
Of course, no comment thread is complete without some bitter snark. For-profit healthcare system does exactly what it has been designed to do: making profit, one cynic jeered. Another chimed in: Its a racket between the old boys from MBA schools making side deals in the back room.
The snark seems to capture the emotional truth of most amputees. Unlike the car marketplace, the prosthesis marketplace isnt one that most people enter by choice. And in the car market, buyers negotiate directly with sellers and can opt out at any point, giving them real bargaining power. In the prosthetics market, theres little negotiation to speak ofat least, little that involves the consumer.
Instead, the bargaining takes place among device manufacturers, insurance companies, government agencies, and healthcare conglomerates. And for better or worse, the starting point for those discussions is the L-Code system.
IF YOURE NOT FAMILIAR WITH L-CODES, theyre part of Medicares Healthcare Common Procedure Coding System (HCPCS), which providers and payers use to identify every procedure and device. The HCPCS is the common language of healthcare finance, and its spoken by everyone who participates in the marketplace. Except patients.
HCPCS codes for orthotic and prosthetic devices are designated by the prefix L. Each component of your prosthesis, from the $30,000 bionic knee (L-) to the $3 one-ply sock (L-), has its own L-Code or combination of codes. A single leg typically consists of 15 to 20 distinct L-Codes, and each code carries a standardized reimbursement rate thats established by Medicare. The rates vary by state, and they arent binding on private insurers or other payers (such as the VA or workers comp agencies), who can negotiate their own rates.
When your prosthetist assembles your leg, the clinic also assembles a list of L-Codes and their corresponding payments. Add them all up, and thats what your device costs. A claim for that amount gets sent to your insurer; a check for that amount gets sent to the clinic. Heres a simplified example for an above-knee prosthetic leg delivered to a Medicare patient:
Sources: Dale Berry, Prosthetic Xpert Consulting; MedicareIt seems like a pretty thorough accounting on the surface. But, like every other healthcare invoice, this one reveals nothing about the underlying costs upon which the prices are based. What percentage of that $62,840 covers the manufacturers up-front investment in research, product development, materials, labor, manufacturing, shipping, and other costs of producing the device and bringing it to market? How much gets siphoned off by the insurer and the health-plan administrator? What portion do corporate shareholders add to their investment portfolios? Whats left over for the prosthetic clinic?
Dale Berry, a seasoned prosthetist and longtime Hanger executive who now operates Prosthetic Xpert Consultation, gave Amplitude some realistic estimates. These numbers are reasonable but inexact; they pack a tremendous amount of real-world variation into a single number. But theyre close enough to illustrate some of the broad market forces that drive prices.
The C-Leg is the number-one selling knee in the world, and its got an established price as set through Medicare and the insurance companies, says Berry. As a prosthetist, I buy the kneejust the knee, not the whole prosthesisfor around $20,000, and Medicare reimburses at around $32,000. So I make a $12,000 profit on that knee.
But its not pure profit because, unlike every other professional clinician, prosthetists arent paid on a fee-for-service basis. The clinical care they provide is bundled together with the cost of the device itself. So the $12,000 markup has to pay for every office visit the patient makes over the three to five years of that devices useful life. Many hours of the prosthetists time and expertisefrom initial assessment, fitting, and fabricating to routine maintenance, adjustment, and troubleshootingare covered by that $12,000 payment. So are all the hours spent on insurance filings, appeals, and other administrative paperwork. Professional education, technology upgrades, staff salaries, rent, office supplies, and all the clinics other business expenses come out of the $12,000, too. It also has to cover denied and unreimbursed claims.
To use the analogy of a prosthesis versus a car: When youre buying a car, you need to look at not only the price of the car but also the cost of ownership, says Joe McTernan, director of health policy and advocacy for the American Orthotic and Prosthetic Association. That includes insurance, oil changes, brake replacements, filters, tires, all the things that go into maintaining it.
If the family sedans ownership cost were bundled together with the retail price, the car might sell for, say, $80,000. Instead, you fork over $30,000 for the vehicle itself and pay the ownership costs as you go. If you sell the car after two years, you only pay two years worth of ownership costsand you can claw back a chunk of the original purchase price on the resale market.
None of these dynamics exist in the prosthesis market. The device plus five years worth of clinical care are rolled into a prepaid, nonrecoverable payment thats largely determined by Medicare.
Despite these imperfections, the market might make sense if every case were as simple as this one. But few cases are. To begin with, every insurer reimburses at a different rate for each L-Code. The same knee that brings a $32,000 reimbursement for a Medicare patient might only fetch $30,250 if Aetna is the payer, or $24,750 if the claim is filed with the Iowa Division of Workers Compensation. Moreover, says McTernan, manufacturers dont charge every clinic the same price for components. If you have a large company thats purchasing hundreds or thousands of units a month, their acquisition cost is clearly going to be different from somebody thats purchasing three units a month. And then theres the fact that some patients require far more hours of clinical care than others. One patient needs five appointments [in five years], and another has complex needs and Im seeing them 30 to 35 times, Berry says. The reimbursement for those two patients is identical.

Things get even more tangled when we move beyond the C-Leg and consider other MPKs. Berry pegs the clinics cost for the Genium kneeOttobocks higher-performing alternative to the C-Legat around $30,000. My time, expertise, equipment costs are all exactly the same as for a C-Leg, Berry explains. But Medicare says, Its a microprocessor knee, so it uses the same L-Code [] and gets reimbursed at the same rate. In other words, the $20,000 C-Leg has $12,000 worth of limb care priced into it, while the $30,000 Genium only provides for $2,000 worth, which doesnt come anywhere close to covering the actual cost of delivering the necessary care.
Clinics would never sell components at such steep losses, and that serves neither the patients who need premium technology nor the manufacturers who need to move inventory. Thats where code L-Lower extremity prosthesis, not otherwise specifiedcomes in. L- covers products and services that dont fit squarely within any other L-Code. Because its a catch-all category, Medicare doesnt have a standardized reimbursement rate for L-, so providers can set their own prices and haggle with payers on a case-by-case basis. Its a loophole that clinics canand sometimes doexploit to drive up their earnings. Most prosthetic clinics dont abuse L-, but it happens often enough to create a ripple effect that affects the whole price structure.
Why dont we just add $12,000 to every device and call it a day? Berry asks. This system is broken, and patients get caught in the middle. You cant make heads or tails of it.
YOU MAY HAVE NOTICED THAT THE DISCUSSION so far has focused solely on the tail end of the supply chainthe $12,000 clinical-care markup that gets bundled into the retail price. Whats happening at the other end of the pipeline, where the $20,000 knee gets manufactured?
Thats a far more daunting accounting exercise. Without access to proprietary information, its impossible to factor out the precise component costs of microprocessor knee production. However, a well-qualified manufacturing industry veteran advises Amplitude that $2,000 to $2,500 per unitincluding materials, labor, factory overhead, and product developmentis a realistic estimate. A more conservative projection of $5,000 per unit would still leave device makers a very healthy gross margin of about 75 percent.
These figures are consistent with financial filings from Össur, which has reported an average gross profit (for all products and services, not just microprocessor knees) of 62 percent in this decade. That margin isnt far off the average gross profit for all medical device manufacturers, which various sources place between 55 and 60 percent. Subtract operating costs (such as marketing, sales, distribution, and administrative overhead), taxes, and accounting deductions, and Össurs net profit has averaged 8 percent annually in this decadeagain, consistent with rates reported by other medical equipment makers. (Össurs main direct competitorsOttobock, Blatchford, and Proteorare privately held and therefore not required to publish detailed financials.)
Looking beyond the medical device industry, the average gross profit in auto manufacturing is about 15 percent; construction supplies, 27 percent; consumer electronics, 32 percent; and heavy machinery, 35 percent. The cost of an industrial robot has fallen by half since , from $47,000 to $23,000, and industry analysts expect it drop another 50 percent before this decade is out. Over the same period, the cost of an MPK prosthesiswhose component materials, engineering, and computing power arent far off from a robotshas hardly budged.
Berry counters that its unfair to compare high-volume industries such as consumer electronics or cars with niche industries such as prosthetics. When people tell me that if more people got legs it would become more affordable, I tell them they arent considering all the nuances, he says. They dont know the manufacturing process. Ive been to the facilities where theyre making these devices, and the volume is just not there.
Its also fair to note that other advanced mobility devices (power wheelchairs, for example) have remained as stubbornly expensive as artificial limbs. The same goes for internal prosthetic devices, such as artificial hip and knee implants. Costs have been escalating for decades throughout the US healthcare industry. The prosthetic sectors cost challenges are just part of a much broader problem.
But that doesnt mean its impossible to create a more efficient prosthesis marketone thats easier for consumers to navigate and more equitably balanced between sellers and buyers.
One potential reform, long debated within the O&P profession, is to unbundle clinical care from the sale of the device and compensate prosthetists on a per-office-visit basis. That would cut 30 to 40 percent off the initial purchase price, enabling more amputees to acquire high-performing limbs. And many clinicians think it would allow them to provide better care and get better outcomes for patients.
Since the day I moved to this country, Ive thought the billing system of paying for the product doesnt serve the patient or the practitioner, says Berry, who began his career in Canadas single-payer healthcare system. Its archaic, and it doesnt make any sense whatsoever. Were not having this conversation in Canada, Germany, Sweden, England, or anyplace else. This conversation doesnt exist in those countries.
Theres been a lot of discussion about that, adds McTernan. Younger prosthetists are saying, The people I took graduate classes with, who are now rehab doctors or physical therapists or some other type of clinician, are all getting paid based on their time, intensity, and skill. So why am I getting paid to provide a device? I understand that, but one problem is that doctors are no longer being reimbursed strictly on time, intensity, and skill. They are starting to move toward a value-based care system, where they set their reimbursement based on patient outcomes.
Value-based care is another reform that has many supporters within the industry. Thats the philosophy behind Medicares recent proposal to expand coverage for MPKs, a reform the major manufacturers pushed for. The data suggest that MPKs, though more expensive, ultimately save money by reducing falls, injuries, and other adverse outcomes. Initiatives such as the Limb Loss and Preservation Registry will make value-based pricing more achievable by collecting the data necessary to identify optimal limb-care solutions.
While changes in clinician compensation might help, new production and distribution models are the surest way to empower consumers. Startups such as Open Bionics, Levitate, Unlimited Tomorrow, and Hutchisons ProsFit are circumventing the L-Code-mediated healthcare complex entirely and selling directly to amputees. Theyre testing the theory that a market which prioritizes affordability, convenience, and customer choice can drive sales volumes upward, push prices downward, accelerate technological innovation, and maintain very high clinical care standards, while serving vastly more amputees than the present system.
The industrys leaders arent sitting on the status quo. Össur, Ottobock, Hanger, and other major players are attempting to lower costs and reach more customers by introducing new technologies, improving clinical care, and lobbying for more generous coverage. They rightly note that the present system, however imperfect, has improved countless lives and produced miraculous outcomes that wouldnt have even seemed possible a generation ago.
But the current market leaves too many amputees frustrated, confused, and angry. Most damning of all, it leaves millions of amputees around the globe completely priced out of the market. Thats Alan Hutchisons fundamental critique, and the target of the cynics snark: How effective can a marketplace be if it fails to provide any solution at all for so many of its customers?
One commenter in Hutchisons LinkedIn debate opined that its impossible to put a fair price on mobility, so why bother trying? Mobility for anyone is invaluable, Hutchison responded. This, however, should not be exploited.
