What Medicare Part B Does NOT Cover

Understanding what's not covered helps avoid surprise costs and billing issues:

Routine Foot Care

General foot care like nail trimming is not covered unless you have a systemic condition affecting your feet (like diabetes with neuropathy).

Experimental Treatments

Treatments not FDA-approved or considered investigational are not covered by Medicare.

Cosmetic Wound Care

Scar revision or treatment for cosmetic purposes only (not medically necessary) won't be covered.

Over-the-Counter Supplies

Basic gauze, tape, and supplies you can buy without a prescription typically aren't covered.

Services Without Documentation

Even covered services can be denied if proper documentation proving medical necessity isn't provided.

Documentation Requirements for Medicare Coverage

Medicare requires comprehensive documentation to approve and reimburse wound care services. Missing or incomplete documentation is the #1 reason for claim denials.

Wound Photography

High-quality photos with measurement ruler showing wound size, depth, tissue type, and surrounding skin condition. Required at initial visit and regular intervals.

Medical Necessity

Clear documentation explaining why advanced treatment is needed, what standard treatments failed, and expected outcomes. Must justify each service billed.

Measurements

Length, width, and depth in centimeters. Wound area calculation. Undermining or tunneling measurements. Tracked over time to show healing progress or lack thereof.

Treatment Plan

Detailed care plan including frequency of visits, specific treatments, expected timeline for healing, and measurable goals. Updated as wound status changes.

Frequently Asked Questions

Common questions about Medicare Part B wound care coverage
Does Medicare cover mobile wound care visits at home?

Yes. Medicare Part B covers mobile wound care visits when you are homebound or have difficulty traveling to a clinic. Providers must document that in-home care is medically necessary due to mobility limitations. Covered services include wound assessments, treatment, debridement, and dressing changes performed in your home.

What is the Medicare deductible for wound care in 2024?

The Medicare Part B deductible for 2024 is $240 per year. After the deductible is met, Medicare pays 80% of the approved amount and you pay 20%. If you have a Medigap (Medicare Supplement) plan, it typically covers the 20% coinsurance, resulting in little to no out-of-pocket cost after the deductible.

Are amniotic membrane grafts covered by Medicare Part B?

Yes. Medicare Part B covers amniotic membrane grafts and other cellular- and tissue-based products (CTPs) for chronic wounds that have not healed after at least 30 days of standard care. Coverage requires documentation of medical necessity, failure of conventional treatments, appropriate wound measurements, and use of Medicare-approved products with proper coding.

How many wound care visits does Medicare cover per month?

Medicare does not set a fixed monthly limit on wound care visits. Coverage is based on medical necessity. If weekly or bi-weekly visits are required for debridement, dressing changes, or monitoring, Medicare will cover them when properly documented. Typical care ranges from 1–4 visits per month depending on wound severity.

Does Medicare cover wound care for diabetic foot ulcers?

Yes. Medicare Part B covers wound care for diabetic foot ulcers, including debridement, offloading devices, negative pressure wound therapy, and skin substitutes. Diabetic wound care is considered medically necessary due to the high risk of infection and amputation. Medicare also covers therapeutic shoes and orthotics for eligible diabetic patients.

What happens if Medicare denies my wound care claim?

If a claim is denied, you have the right to appeal. Most denials occur due to incomplete documentation rather than non-covered services. Healix360 providers manage appeals by submitting additional medical records and clinical justification. You are not billed while an appeal is pending unless Medicare issues a final denial after all appeal levels are exhausted.

Can I see a wound care specialist without a referral?

With Original Medicare (Parts A and B), no referral is required to see a wound care specialist. You may self-refer or be referred by your primary care physician. Some Medicare Advantage plans do require referrals, so plan rules should be verified in advance. Healix360 assists with this during eligibility verification.

Does Medicare cover wound care supplies like dressings?

Medicare Part B covers wound care supplies when they are applied by a healthcare professional as part of treatment. This includes advanced dressings used during visits. Supplies needed for self-care between visits may require prior authorization or may be covered under Part B Durable Medical Equipment (DME) benefits with separate cost-sharing.

What is the difference between Medicare Part B and Medicare Advantage for wound care?

Medicare Part B (Original Medicare) covers 80% of wound care services after the deductible and has no network restrictions. Medicare Advantage plans must cover the same services but may require prior authorization, limit providers to a network, or have different cost-sharing. Some Advantage plans offer extra benefits beyond Part B.

How long does Medicare cover wound care treatment?

Medicare covers wound care for as long as it is medically necessary and the wound is improving or requires ongoing management. There is no time limit on coverage. Chronic wounds remain covered as long as documentation shows progress or that appropriate alternative treatments are being tried, until the wound heals or reaches maximum medical improvement.
