Editorial Policy and Data Standards
How we source data, calculate numbers, handle ads and medical information, and fix mistakes.
What does MedSupplyDex publish?
MedSupplyDex publishes a directory of Medicare-enrolled medical equipment suppliers, ranked lists calculated from that directory, free tools, and plain-language guides about choosing and paying for equipment.
Where does the information come from?
Supplier listings come from a public Medicare medical equipment supplier file. Guides are based on Medicare's own materials, including Medicare Coverage of Durable Medical Equipment & Other Devices and the CMS DMEPOS information center. Each guide lists the sources it relies on at the bottom of the page.
How are counts, rankings and comparisons made?
All numbers are computed by software from the data file. We do not edit individual supplier records by hand, and we do not estimate missing values. City and state comparisons use the same counts shown on each page. Ranked city lists include only cities with at least 50 listings so that one supplier cannot swing a percentage. The methodology page describes every calculation and its limits.
Can suppliers pay to change their listing or ranking?
No. Listings, counts and rankings are not for sale, and suppliers cannot pay to be placed higher. Advertising may appear on the site; it is separate from the data and does not affect any listing or ranking.
How do we handle medical and coverage information?
Guides and tools are general information, not medical, legal or financial advice. Coverage rules vary by item, plan and situation and can change, so we point readers to Medicare, their plan and their clinician for decisions. Guides have not been reviewed by a licensed clinician unless a page names a reviewer.
How do corrections and updates work?
Supplier details usually need to be corrected in the source Medicare record. If you find an error on a page, use the contact page. We review reports and correct the site, and we update the data snapshot when a new version of the file is published. Each guide shows the date it was last reviewed.
This page is general information, not medical or legal advice. Verify coverage details with Medicare, your plan, and your clinician.
