What is a Durable Medical Equipment (DME) supplier?

A DME supplier is a Medicare-enrolled business that provides medical equipment prescribed by doctors for use at home. They must meet Medicare quality standards and be accredited to receive reimbursement. Always verify your supplier's NPI number before purchasing equipment.

What should I ask a oxygen delivery systems supplier before ordering?

Ask if they accept Medicare assignment (meaning Medicare pays them directly and you only owe 20%), verify their NPI number, confirm they have your specific equipment in stock, and ask if they can bill your secondary insurance. Also confirm they are accredited and can handle prior authorization if required.

About Oxygen Delivery Systems

Oxygen delivery systems include concentrators, portable oxygen units, and liquid oxygen equipment prescribed for patients with chronic respiratory conditions.

How to Choose a Medicare Oxygen Delivery Systems Supplier

Ask about backup equipment and emergency response

Oxygen is life-critical. Choose a supplier with 24/7 emergency delivery capability, a loaner equipment policy, and experience managing the 36-month Medicare rental-to-ownership timeline.

Verify Medicare assignment status

Ask "Do you accept Medicare assignment?" A supplier who accepts assignment cannot charge you more than the Medicare-approved amount — your cost is capped at 20% coinsurance after your deductible. Non-participating suppliers can charge up to 15% more.

Check accreditation from a CMS-recognized body

All Medicare DME suppliers must be accredited by a CMS-recognized organization: ACHC, HQAA, BOC, ABC, or TCT. Accreditation signals quality standards compliance. You can verify a supplier's accreditation by asking for their accreditation certificate or checking with the accrediting body directly.

Confirm NPI number and active Medicare enrollment

Every Medicare supplier has a National Provider Identifier (NPI). You can verify any supplier at nppes.cms.hhs.gov. Also confirm their Medicare billing number is active by calling 1-800-MEDICARE — this protects you from suppliers whose billing privileges have been revoked.
