Short answer: Yes. when clinically appropriate, we offer same-day prosthetic fitting. fort myers patients can benefit from our on-site laboratory, helping reduce wait times and speed up rehabilitation. <. we provide ongoing adjustments, repairs, maintenance, and rehabilitation to ensure every patient continues to benefit from their prosthetic device. this commitment to long-term care is reflected in our outstanding amputee clinic fort myers reviews and high patient retention rate. <, in most cases. Medicare Part B covers prosthetic limbs and pays 80% of the approved amount after your $283 annual deductible in 2026. Most private plans cover them too, though Florida plans can legally impose dollar caps that many other states prohibit. Veterans enrolled in VA health care generally pay nothing.
The harder question isn’t whether you’re covered. It’s what you’re covered for, because the gap between an approved basic leg and an approved microprocessor knee is roughly $50,000, and that decision is made on paperwork filed before you ever try the device.
Key Takeaways
- Medicare Part B covers prosthetic limbs: you pay a $283 deductible + 20% coinsurance in 2026, with no annual out-of-pocket cap on Original Medicare.
- A Medigap policy covers that 20% — often the difference between a $12,000 bill and nothing.
- Six microprocessor component codes require prior authorization before delivery. Miss this and the claim can be denied outright.
- Your K-level decides your components. K3 unlocks microprocessor knees; K2 does not.
- There is no five-year replacement rule. Medicare policy explicitly supersedes it — replacement turns on three documented grounds, not a calendar.
- Florida has no prosthetic parity law, so Florida private plans may legally cap prosthetic benefits.
- A denial is not final. Most are won on documentation, not on the merits of the device.

1. Coverage at a Glance
| Payer | Covers a prosthetic limb? | What you pay | Benefit caps | Prior auth | Replacement |
|---|---|---|---|---|---|
| Medicare Part B | Yes | $283 deductible + 20% | No cap on your 20% | Yes — 6 codes | When medically necessary |
| Medicare + Medigap | Yes | Usually $0–$283 | — | Same as Part B | Same as Part B |
| Medicare Advantage | Yes (at least Part B level) | Plan cost-sharing | Plan OOP max applies | Part B rules + plan’s own | Per plan |
| Private (Florida) | Usually | Deductible + coinsurance | Legal in FL | Usually required | Per policy |
| Florida Medicaid | Yes, with PA | $0 to minimal | Tight component limits | Yes | Restrictive |
| VA health care | Yes | $0 | None | Internal process | Generous |
| Workers’ comp | Yes | $0 | None | Yes | Covered for life |
Bottom line: the VA and workers’ compensation are the most complete coverage available. Medicare is reliable but leaves an uncapped 20% unless you carry Medigap. Private plans in Florida carry the most risk of a hard dollar cap.
2. Does Medicare Cover Prosthetics?
Yes. when clinically appropriate, we offer same-day prosthetic fitting. fort myers patients can benefit from our on-site laboratory, helping reduce wait times and speed up rehabilitation. <. we provide ongoing adjustments, repairs, maintenance, and rehabilitation to ensure every patient continues to benefit from their prosthetic device. this commitment to long-term care is reflected in our outstanding amputee clinic fort myers reviews and high patient retention rate. <. Prosthetic limbs are covered under Medicare Part B, under the prosthetic devices benefit — not under durable medical equipment, which is a separate category with different rules.
What you need to qualify
| Requirement | Detail |
|---|---|
| Physician’s order | Must document medical necessity |
| K-level assessment | Documented functional classification (see §4) |
| Enrolled supplier | Your prosthetist must be Medicare-enrolled |
| Prior authorization | Required for certain components (see §3) |
Coverage is governed by Medicare’s Local Coverage Determination for Lower Limb Prostheses (LCD L33787) — the document your prosthetist’s billing team works from whether they mention it or not.
What Medicare pays in 2026
| Line item | Amount |
|---|---|
| Annual Part B deductible | $283 |
| Medicare pays | 80% of approved amount |
| You pay | 20% coinsurance |
| Annual out-of-pocket cap (Original Medicare) | None |
What that means in dollars:
| Approved amount | Your 20% share |
|---|---|
| $10,000 (basic below-knee) | ~$2,000 |
| $20,000 (mid-range) | ~$4,000 |
| $60,000 (above-knee, microprocessor knee) | ~$12,000 |
Plus the $283 deductible if you haven’t met it.
Medigap changes the math completely
If you carry a Medicare Supplement (Medigap) policy, most plan letters cover the Part B 20% coinsurance in full — a $12,000 obligation becomes little or nothing.
Two exceptions worth knowing: Plan K covers 50% of Part B coinsurance and Plan L covers 75%, both with an annual out-of-pocket limit after which they pay 100%. Check your plan letter rather than assuming.
For amputees in Southwest Florida, where Medigap enrollment is common, this routinely decides whether someone gets the right limb or settles for a cheaper one. If you’re on Original Medicare without a supplement and a prosthesis is coming, review your options during your next enrollment window before the fitting process starts.
Medicare Advantage
Medicare Advantage (Part C) must cover at least what Original Medicare covers. In practice it often handles the 20% better — but adds network restrictions and its own authorization layer.
Confirm two things before your first appointment:
- Is your prosthetist in network? Prosthetics is a narrow specialty and MA networks are thin.
- What is your plan’s out-of-pocket maximum? Unlike Original Medicare, MA plans have one — and it works in your favor.
Bottom line: Medicare covers the limb. Whether you can afford your share depends almost entirely on whether you have Medigap or an MA out-of-pocket maximum.
3. The Prior Authorization Rule Nobody Warns You About
This is the most common reason a prosthetic claim stalls — and most patients hear about it only after it has already delayed them. Since December 1, 2020, Medicare has required prior authorization nationwide for six lower limb prosthetic HCPCS codes.
The six codes
| Code | Component |
|---|---|
| L5856 | Microprocessor knee — swing and stance phase control |
| L5857 | Microprocessor knee — swing phase only |
| L5858 | Microprocessor knee — stance phase only |
| L5973 | Microprocessor-controlled ankle-foot system |
| L5980 | Flex-foot system |
| L5987 | Shank foot system with vertical loading pylon |
Every microprocessor knee falls under this rule.
What it means for you
| Issue | Practical consequence |
|---|---|
| Timing | Authorization must happen before delivery, not after. A device delivered first can be denied outright — and you can be left holding the bill. |
| Documentation | Decisions are made on paper only. If your chart says limited household ambulator, a microprocessor knee is denied regardless of how well you’d use one. |
How long authorization actually takes
Two different clocks get confused here, so it’s worth separating them.
| Clock | Timeframe |
|---|---|
| CMS decision — standard review | 7 calendar days (reduced from 10 business days on 1 Jan 2025) |
| CMS decision — expedited review | 2 business days, where the standard timeframe would seriously jeopardize your health |
| CMS decision — resubmission | Up to 20 business days |
| Real-world total | Commonly 2–6 weeks, because gathering physician notes, completing the evaluation, and correcting a first submission all happen before the clock starts |
The CMS decision itself is fast. What takes weeks is assembling documentation good enough to survive it. Count backward from any surgery date, return-to-work date, or event, and ask your prosthetist when the submission actually goes out, not just when a decision is expected.
Bottom line: if a microprocessor component is on your prescription, ask your prosthetist to confirm prior authorization was submitted and approved before fabrication starts. Get the approval number.
4. K-Levels: The Number That Decides Your Limb
Medicare classifies every lower-limb amputee on a five-point functional scale. Your K-level determines which components are considered medically necessary, and therefore which ones get paid for.
| Level | Function | Typically unlocks |
|---|---|---|
| K0 | No ability or potential to ambulate | Prosthesis generally not covered |
| K1 | Household ambulator, fixed cadence | Basic feet, manual locking knees |
| K2 | Limited community ambulator; curbs, stairs, uneven ground | Multiaxial feet, basic hydraulic knees |
| K3 | Community ambulator, variable cadence | Energy-storing feet, microprocessor knees |
| K4 | High impact, athletics, children | Full component range |
The K2 → K3 line is the one that matters
Microprocessor knees become justifiable at K3 and are routinely denied at K2. That single classification is worth tens of thousands of dollars.
Why you should question an early K-level
K-levels are frequently assigned early, weeks post-op, deconditioned, and not representative of how you’ll function in six months. That conservative assessment then follows you through every subsequent claim.
If your documented level doesn’t match how you actually live:
- Ask your physician and prosthetist to reassess together.
- Document specific evidence — distances walked, terrain, work demands, fall history.
- Have the updated level recorded in your chart before the new prescription is written.
Bottom line: this is one of the few points in the process where advocating for yourself directly changes what you walk on.
5. How Often Will Medicare Pay for a New Prosthetic Leg?
There is no five-year rule. This is the most persistent myth in prosthetic coverage, and Medicare’s own policy says so directly.
Medicare’s Lower Limb Prostheses Policy Article (A52496) sets out the replacement criteria and states explicitly that this rule supersedes any rule that provided a 5-year or other replacement rule for prosthetic devices. If you’ve been told you have to wait five years, that is not Medicare policy.
The three official grounds for replacement
Medicare covers replacement when your treating practitioner orders one for any of these reasons:
| # | Ground | Notes |
|---|---|---|
| 1 | A change in your physiological condition | Limb volume loss, weight change, surgical revision. The most common reason, and it often occurs well inside five years. |
| 2 | Irreparable wear of the device or a part of it | Normal deterioration that has degraded function. |
| 3 | Repairs would cost more than 60% of the replacement device or part | The “60% rule” — see below. |
A documented change in functional level (K2 → K3, for example) doesn’t sit in this list on its own, but it can support a new prescription with different components.
The 60% repair rule
Repairs are covered under Part B. When a repair would cost more than 60% of the cost of a replacement device — or of the part being replaced — replacement is the covered path instead.
Your prosthetist must retain documentation of what was replaced, why, and the labor involved, and produce it on request. Ask for a copy for your own records.
Sockets are separate
A replacement socket does not require a whole new prosthesis and is covered on its own. Most new amputees need at least one socket replacement in the first 12–18 months as limb volume stabilizes. That’s expected, not exceptional.
6. Does Private Insurance Cover Prosthetics?
Usually — but with far more variation than Medicare, and Florida patients face a specific disadvantage.
Florida is not a prosthetic parity state
Roughly half of U.S. states have passed prosthetic parity laws requiring private insurers to cover prosthetic limbs on par with other medical benefits. Florida has not.
What a Florida plan may legally do that a parity state prohibits:
- Impose an annual dollar cap — $5,000 and $10,000 caps still appear in Florida policies
- Impose a lifetime cap
- Limit you to one device per limb, per lifetime
- Exclude replacement components or activity-specific limbs entirely
The five things to check in your policy
| # | Check | Why it matters |
|---|---|---|
| 1 | Prosthetic benefit cap — annual and lifetime | The single most important number in your policy |
| 2 | Prior authorization requirements | Nearly always required above a basic device |
| 3 | In-network status | Out-of-network on a $40,000 device can double your share |
| 4 | Replacement language | How often, and under what conditions |
| 5 | Whether your plan is self-funded | Large-employer plans usually are — governed by federal ERISA, not Florida regulation. Changes who you appeal to. |
Look for the prosthetic benefit language specifically — not the general durable medical equipment section — and search for the word “maximum.”
Bottom line: read the cap before you choose components, not after. In Florida there’s no law protecting you from one.
7. Medicaid, VA, and Workers’ Compensation
Florida Medicaid
Florida Medicaid covers prosthetic devices with prior authorization, though component approval is tighter than Medicare’s — microprocessor components are approved rarely and require substantial documentation.
The bigger obstacle here is eligibility. Florida has not expanded Medicaid, so adult eligibility is significantly narrower than in most states. Many working adults who would qualify in a neighboring state do not qualify here.
If you’ve been told you earn too much for Medicaid but can’t afford coverage, look at ACA marketplace plans during open enrollment — prosthetic devices fall under the essential health benefits framework, though specific coverage still varies by plan.
Veterans
If you’re enrolled in VA health care, the VA generally provides prosthetic limbs, components, repairs, and replacements at no cost.
VA standards are among the most generous in the country. Veterans are routinely approved for things private insurance denies outright:
- A backup limb, so you’re not immobilized during a repair
- Activity-specific limbs — a shower leg, a running blade, a swim leg
- More frequent replacement cycles
Southwest Florida has a large veteran population, and in our experience many eligible veterans have never enrolled or assume they don’t qualify. If you served, check your eligibility before you spend anything.
Workers’ compensation and liability settlements
| Situation | Coverage |
|---|---|
| Workplace injury | Workers’ comp typically covers the prosthesis in full, including replacements for life — often the most complete coverage available to anyone. |
| Accident caused by someone else | A liability settlement should account for lifetime prosthetic costs, not one limb. |
On settlements: a below-knee amputee will spend more over a lifetime on socket replacements, liners, and repairs than on the original device. That projection needs to be built by a prosthetist who can document component lifespans and replacement intervals — not estimated by an attorney working from a single quote.
8. What to Do If You’re Denied
A first denial is not a final answer. Prosthetic denials are overturned on appeal at a meaningful rate, and appeals usually succeed or fail on documentation quality, not on the merits of the device.
The six-step appeal process
Step 1 — Get the denial in writing.
Not the phone explanation. The written determination with the specific code or policy cited. You cannot rebut what you haven’t read.
Step 2 — Identify which kind of denial it is.
| Type | Winnable? |
|---|---|
| Documentation gap — something wasn’t filed | Yes, usually straightforward |
| K-level mismatch — chart doesn’t support the components | Yes, with reassessment |
| Plan exclusion — a hard cap | Requires a different strategy |
Step 3 — Get a coordinated letter of medical necessity.
From your physician and your prosthetist — two clinicians, one letter. It should state your functional level with specific evidence (distances walked, terrain, work and family demands, fall history) rather than asserting a conclusion.
Step 4 — Include functional evidence.
Gait assessments, therapy notes, and documented outcomes with a trial device carry more weight than clinical opinion alone.
Step 5 — Escalate through every level.
| Payer | Appeal path |
|---|---|
| Medicare | Five levels of appeal |
| Private plan | Internal appeal → independent external review |
External review is often where caps and medical-necessity denials finally get overturned.
Step 6 — Don’t do it alone.
A clinic that handles billing in house has fought these before and knows what reviewers want to see. If your prosthetist tells you a denial is the end of the road, get a second opinion from one who does their own billing.
9. Documentation Checklist
Bring or request these before your first fitting appointment. Missing pieces are the most common cause of delay.
- Physician’s prescription and clinical notes establishing medical necessity
- Documented K-level assessment
- Amputation history and operative report
- Physical therapy notes and any gait assessments
- Current insurance card and policy documents, including the prosthetic benefit section
- Prior authorization confirmation, if microprocessor components are prescribed
- Prior prosthetic records, if this is a replacement

Medicare Part B covers prosthetic limbs as prosthetic devices when a physician documents medical necessity. In 2026 you pay the $283 Part B deductible plus 20% coinsurance, and Medicare pays the remaining 80%. Original Medicare has no annual out-of-pocket cap, but a Medigap policy typically covers your 20%.
Does Medicare cover prosthetic legs?
Yes. when clinically appropriate, we offer same-day prosthetic fitting. fort myers patients can benefit from our on-site laboratory, helping reduce wait times and speed up rehabilitation. <. we provide ongoing adjustments, repairs, maintenance, and rehabilitation to ensure every patient continues to benefit from their prosthetic device. this commitment to long-term care is reflected in our outstanding amputee clinic fort myers reviews and high patient retention rate. <, Medicare covers both below-knee (transtibial) and above-knee (transfemoral) prostheses under Part B, subject to a documented K-level assessment. Microprocessor knees require prior authorization before delivery.
How often will Medicare pay for a new prosthetic leg?
There is no five-year rule — Medicare’s Lower Limb Prostheses Policy Article (A52496) explicitly supersedes it. Replacement is covered on three grounds: a change in your physiological condition, irreparable wear, or repairs costing more than 60% of a replacement. Replacement sockets are covered separately and more often.
Does Medicare require prior authorization for prosthetics?
For certain components, yes. Since December 2020, six lower limb prosthetic codes — L5856, L5857, L5858, L5973, L5980 and L5987 — require prior authorization nationwide. All microprocessor knees fall under this rule. Authorization must be obtained before delivery. CMS decides standard requests within 7 calendar days and expedited requests within 2 business days, but the real-world total is commonly 2–6 weeks once documentation gathering is included.
Does private insurance cover prosthetic limbs?
Most plans do, but terms vary widely. Florida has no prosthetic parity law, so Florida plans may legally impose annual or lifetime dollar caps on prosthetic benefits. Check your policy’s prosthetic benefit language for a maximum before selecting components.
Are prosthetics covered by insurance in Florida?
Generally yes, but Florida is one of roughly half of U.S. states without a prosthetic parity law. Florida plans can impose dollar caps and per-limb limits that would be prohibited in parity states. Self-funded employer plans are governed by federal ERISA rules rather than Florida insurance regulation.
Does the VA cover prosthetic legs?
Yes. when clinically appropriate, we offer same-day prosthetic fitting. fort myers patients can benefit from our on-site laboratory, helping reduce wait times and speed up rehabilitation. <. we provide ongoing adjustments, repairs, maintenance, and rehabilitation to ensure every patient continues to benefit from their prosthetic device. this commitment to long-term care is reflected in our outstanding amputee clinic fort myers reviews and high patient retention rate. <. Veterans enrolled in VA health care generally receive prosthetic limbs, components, repairs and replacements at no cost, often including a backup limb and activity-specific devices that private insurance would deny.
What if my prosthetic claim is denied?
Request the written denial, determine whether it’s a documentation gap, a K-level mismatch, or a plan exclusion, then appeal with a coordinated letter of medical necessity from both your physician and prosthetist. Medicare offers five appeal levels; private plans offer internal appeals plus independent external review.
