• You don’t want to bill Medicare for your services, but you do want enroll in Medicare solely to order and certify.
• You wish to provide services to beneficiaries but do not want to bill Medicare for your services. (In this case, you would need to opt out of Medicare.)
• You want to enroll as a supplier who does not dispense or furnish durable medical equipment, prosthetics, orthotics and supplies (DMEPOS). (You can still use this guide if you dispense Part B drugs used with DMEPOS, such as inhalation drugs.)

Keep Your Information Current

It’s important to keep your enrollment information up to date. To avoid having your Medicare billing privileges revoked, be sure to report the following changes within 30 days:

• a change in ownership
• an adverse legal action
• a change in practice location

You must report all other changes within 90 days. If you applied online, you can keep your information up to date in PECOS. If you applied using a paper application, you’ll need to resubmit your form to update information.
