DME Billing and the Medicare DME Fee Schedule, Explained

2026-07-11 · Caduvo Team

How durable medical equipment gets billed and paid: the DMEPOS fee schedule, rental vs purchase, and payment rates.

A home oxygen concentrator and a hospital bed both get paid by Medicare, but under very different rules. One is a capped rental, the other is a lump-sum purchase. Understanding the DME billing pathway is critical for manufacturers who need to model revenue and set pricing. The Medicare DME fee schedule—officially the DMEPOS fee schedule—determines exactly what a supplier is paid for each item. If you’re launching a device, your reimbursement rate will be pulled from that schedule, assuming you’ve secured a HCPCS code and the item is covered by Medicare. Here’s how that works.

What qualifies as DME for Medicare

Medicare defines durable medical equipment (DME) as equipment that meets four criteria:

So a wheelchair qualifies. A bathtub grab bar does not—it’s not primarily medical. An air purifier fails because it’s useful to anyone. If a device checks all four boxes, it can be assigned a HCPCS code and, if covered, paid under the DMEPOS fee schedule.

Medicare coverage for DME is governed by National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs). For instance, there is an NCD for home oxygen therapy that specifies the conditions under which it’s covered. A device that meets the DME definition but lacks a coverage policy will not be paid, even with a code. You can research coverage rules in the Medicare Coverage Database.

How the DMEPOS fee schedule sets payment rates

The DMEPOS fee schedule is a list of payment amounts for HCPCS codes covering DME, prosthetics, orthotics, and supplies. It is updated quarterly. Each code has a payment amount that represents the maximum Medicare will pay a supplier for that item. The amount is generally based on the lesser of the actual charge or the fee schedule amount. For competitive bidding areas, the rates are the single payment amounts (SPAs) derived from the Competitive Bidding Program (CBP).

CMS publishes the fee schedule as public use files. The key file is the “DMEPOS Fee Schedule” spreadsheet, which you can download from the CMS website. For each HCPCS, you’ll see:

If you’re looking up medicare reimbursement rates for a specific code, you need to check the correct modifier column. The NU column shows the purchase price for new equipment; the RR column shows the monthly rental payment. Many codes have both. The rate calculation method changed after the 21st Century Cures Act: for items not subject to competitive bidding, payments are now based on the average of commercial prices collected from suppliers, instead of the old fee schedule inflation updates. This means rates for non-bid items can shift based on market data.

Rental vs. lump-sum purchase: how Medicare pays

Medicare splits DME into two broad payment categories: capped rental items and normally purchased items.

There is also a category for “inexpensive or routinely purchased” items (purchase price under $150), which are paid on a lump-sum basis, and “frequently serviced” items like ventilators that are continuously rented. The category is determined by CMS and tied to the HCPCS code. If you’re trying to estimate revenue, you must know which category your product falls into, because the payment stream is completely different.

Competitive bidding’s impact on rates

The DMEPOS Competitive Bidding Program (CBP) started in 2011 and has expanded to many geographic areas. Under CBP, CMS selects contracted suppliers through a bidding process. The winning bid prices become the single payment amounts for all suppliers in that competitive bidding area (CBA). For beneficiaries in those areas, Medicare reimburses only the SPA, which is often lower than the original fee schedule rate.

If you’re a manufacturer, the existence of a CBP for your product’s code means that the effective reimbursement rate in many high-population regions is the competitive bid rate, not the published fee schedule. You can check the competitive bidding status of a HCPCS code and CBAs on the CMS website. The rates are often 20–40% lower than the non-bid fee schedule amounts, so they directly affect how suppliers price their equipment and what they can afford to pay you.

Estimating reimbursement for a new product

For a manufacturer launching a device, the reimbursement estimate starts with three questions:

  1. Do you have a HCPCS code? If not, you’ll need to apply for one. Without a code, there is no fee schedule entry. The process of getting a HCPCS code can take 6–12 months.
  2. Is the product covered by Medicare? Check NCDs and LCDs for the indication. If no coverage determination exists, you may need to pursue a LCD or NCD.
  3. What is the payment category and the fee schedule amount? Once you have a code, look up the DMEPOS fee schedule. Identify the modifier columns (NU/RR) and any competitive bidding SPA in your target geographies.

If your product is a new type of existing DME, CMS may assign a gap-fill rate or use crosswalk pricing to set the initial fee schedule amount. Gap-fill means the four DME MACs each set a local rate based on supplier invoices, and CMS averages them. Crosswalk means CMS compares your item to an existing code and adopts its rate. Either way, you’ll need to submit clinical and pricing data to support the rate.

Caduvo’s platform aggregates code-level fee schedule data, coverage policies, and competitive bidding status so you can see the reimbursement picture for a HCPCS code in minutes, not weeks.
