Does Medicare Cover Mobile Wound Care at Home in St. Louis?

Short Answer: Yes — With Specifics

Medicare covers mobile wound care when three basic conditions are met: (1) the service is medically necessary, (2) it is provided by a qualified clinician — in our case, a licensed nurse practitioner practicing within scope, and (3) the visit is properly documented and billed under the correct codes. For patients in St. Louis with a non-healing wound, these conditions are met in nearly every case.

The rest of this article walks through exactly how Medicare covers mobile wound care, what out-of-pocket costs to expect, how Medicare Advantage differs from Original Medicare, and what Gateway handles on your behalf.

Medicare Part B Coverage for Nurse Practitioner Wound Visits

Original Medicare has two main parts relevant to wound care:

• Part A covers inpatient hospital stays and short-term skilled nursing facility care after a qualifying hospital stay.
• Part B covers outpatient services, including clinician office visits, nurse practitioner home visits, lab work, and medical supplies. This is where mobile wound care lives.

Under Part B, a nurse practitioner is an authorized Medicare provider and can bill for evaluation and management (E/M) visits, wound debridement, and other covered services in the patient's home. The home visit is billed using place-of-service code 12 (home) or 13 (assisted living), with the same CPT codes as a clinic visit. Medicare pays 80% of the allowed amount after the annual deductible, and the patient — or their supplemental insurance — pays the remaining 20%.

"Homebound" vs. "Mobility-Limited" — The Distinction That Matters

Patients are often told they need to be "homebound" to receive home-based care, which confuses two very different Medicare programs:

• Medicare Home Health (Part A-style benefit): Requires the patient to be legally "homebound" — leaving the home requires considerable and taxing effort. This is the standard for the Home Health Agency benefit, which bundles skilled nursing, therapy, and home health aide services under a 60-day plan of care.
• Medicare Part B outpatient home visits (our model): Does NOT require homebound status. The relevant standard is that the home is a reasonable and appropriate setting for the service to be provided. Transportation difficulty, mobility impairment, or risk of clinical worsening from travel are all acceptable justifications.

This matters for most wound care patients: someone with a DFU who walks with a cane, drives rarely, and can't realistically make twice-weekly clinic visits is not "homebound" in the strict Part A sense, but is absolutely appropriate for Part B mobile wound care. We see patients under both standards and verify which pathway fits before the first visit.

What Wound Care Supplies Medicare Covers

Supplies fall into two buckets, each handled differently:

Surgical Dressings (Medicare DME Benefit)

Medicare covers "surgical dressings" — the advanced wound dressings applied by and prescribed by a clinician — under the durable medical equipment (DME) benefit. Covered categories include alginate dressings, foam dressings, collagen dressings, hydrogels, hydrocolloid dressings, and antimicrobial dressings (silver, iodine). Coverage requires a physician or NP order with specific wound characteristics documented. Gateway generates this documentation and coordinates supply delivery with Medicare-contracted DME providers — patients rarely pay out-of-pocket for covered dressings.

Wound Vac / Negative Pressure Wound Therapy (NPWT)

Wound vac therapy is covered under a separate Local Coverage Determination (LCD). Qualifying criteria include specific wound types (Stage 3–4 pressure ulcers, diabetic foot ulcers, dehisced surgical wounds, and others) and demonstrated conservative care first. Gateway NPs document the qualifying criteria, initiate wound vac at the bedside, and coordinate pump rental through the DME provider. Standard Part B cost-sharing applies.

Over-the-Counter Supplies

Basic supplies like gauze, tape, and gloves used for routine home dressing changes by the patient or family are typically not covered — these are considered personal care items. Ask the NP at your first visit what's covered and what you'll need to buy.

Medicare Advantage — Same Services, Different Rules

Medicare Advantage plans (Part C) are required by law to cover everything Original Medicare covers, and most cover some additional benefits. For wound care, practical differences between Original Medicare and Medicare Advantage include:

• Networks: Advantage plans may require in-network providers. We participate with most major St. Louis-area Advantage plans; we verify before the first visit.
• Prior authorization: Some plans require pre-authorization for wound vac, advanced dressings, or visit frequency above a threshold. Gateway handles all authorization paperwork.
• Copays: Advantage plans use fixed copays (e.g., $20 per visit) instead of 20% coinsurance. Some plans waive copays for certain home-based services — we confirm this during verification.
• Supply sourcing: Advantage plans often have preferred DME vendors that differ from Original Medicare's; we route supply orders accordingly.

If you have an Advantage plan, the same care is covered — the paperwork behind the scenes is different. That paperwork is our job, not yours.

Copays, Deductibles, and What to Expect Out of Pocket

Under Original Medicare Part B in 2026:

• Annual Part B deductible: Applies once per year before Medicare begins paying its share.
• 20% coinsurance: Applied to the Medicare-allowed amount for each covered service after the deductible is met.
• Medicare Supplement (Medigap) plans: Plans F, G, and N are the most common supplements and typically cover the 20% coinsurance in full. With a Medigap plan, most wound patients have zero out-of-pocket cost per visit after the Part B deductible is met.
• Medicare Advantage copays: Typically range from $0–$40 per home visit depending on the plan. Some plans classify NP home visits as "office visits" with a low copay; others categorize them differently.
• Medicaid dual eligibility: Patients with both Medicare and Medicaid typically have their coinsurance or copays covered by Medicaid.

We verify your specific plan's cost-sharing before the first visit and tell you exactly what to expect. No surprise bills.

How Gateway Handles Billing — So You Don't Have To

Gateway is a Medicare-enrolled provider. Practically, that means:

• We bill Medicare (or your Advantage plan) directly for every visit.
• We submit documentation and authorizations on your behalf — you don't fill out insurance forms.
• We coordinate DME supply orders with the contracted providers in St. Louis.
• We absorb the upfront verification work — before your first visit, a Gateway care coordinator confirms plan eligibility, copay structure, and any prior authorization needs. This verification is free.
• After visits, you receive a standard Medicare Summary Notice (Original Medicare) or Explanation of Benefits (Advantage) from the insurer. If anything unexpected appears, we research and resolve it with the insurer on your behalf.

The phrase "no patient paperwork" is literal — aside from signing a one-time patient consent and insurance assignment form at the first visit, you do not fill out anything.

Real-World Scenarios in St. Louis

A few common patterns we see among St. Louis patients:

• Original Medicare + Plan G Medigap: Typical out-of-pocket cost per wound visit: $0 after the annual Part B deductible is met. Supplies covered as described above.
• Medicare Advantage HMO: Typical out-of-pocket cost per wound visit: $0–$40 copay depending on plan; prior authorization sometimes required for visit frequency or wound vac.
• Medicare + Medicaid (dual eligible): Typical out-of-pocket cost: $0. Medicaid covers cost-sharing Medicare leaves behind.
• Medicare only (no supplement, no Advantage): 20% of the Medicare-allowed amount per visit after the deductible. Still significantly less expensive than ER-based wound management.

Every patient's situation is different — we verify specifics, never assume. For more on the conditions we treat, see our guides on pressure ulcer infection signs and what happens when a diabetic foot ulcer goes untreated. To start the process, visit our contact page or submit a referral online.

Next Step: A Free Coverage Verification

If there's a wound at home that needs attention, the first step is a simple phone call. Our care coordinator asks for basic patient and insurance information, confirms Medicare or Advantage eligibility with the payer in real time, and — if you're ready — schedules the first home visit within 24–48 hours. There's no cost, no commitment, and no pressure. Verifying eligibility first means you know exactly what your out-of-pocket will look like before any services are rendered.
