Medicare Credentialing Scenarios

Medicare enrollment does not automatically transfer when you move to another state, join a different practice or add a location. The required application or enrollment update depends on the change. Confirm what Medicare requires and the applicable billing effective date before submitting claims for the new arrangement.

Here are some common scenarios where a Medicare enrollment specialist is helpful:

  1. Did you open a new practice location? Have you notified Medicare so you can bill for the services?
  2. Did a physician leave your practice in the past? Are you aware that Medicare must be notified of this change?
  3. Have you changed billing companies? This new agency must be on file with Medicare.
  4. Did you have a change of ownership? This must also be provided to Medicare.
  5. Are your claims being denied and you are not sure why?
  6. Are you opening an office and not sure where to start?
  7. Would you like to bill for DME but don’t have a supplier number?

Medicare Application Types

You can use PECOS to enroll online or submit the applicable paper application. We recommend PECOS where available because it supports electronic submission, document uploads and application tracking. Requirements and processing times depend on the application and your Medicare Administrative Contractor.
The direct link for each Medicare provider/supplier enrollment application is shown below:
  1. Institutional/Facilities: CMS-855A
  2. Clinics/group practices and certain other suppliers: CMS-855B
  3. Physicians and non-physician practitioners (including clinical psychologists, nurse practitioners, therapists, physician assistants and most other provider types): CMS-855I
  4. Reassignment of benefits, including linking a provider to a Medicare group: CMS-855I. Reassignment reporting is now included in CMS-855I; CMS-855R has been discontinued.
  5. Ordering, certifying and prescribing providers: CMS-855O
  6. Durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) suppliers: CMS-855S
  7. PECOS
  8. We have a very helpful tutorial on using PECOS which can be found here.

Retroactive Billing for Medicare

The short answer is Yes, but there are some specifics that you need to be aware of. Retroactively billing Medicare is critical for most organizations as providers often start without having a Medicare number. Your retroactive period begins once an application has been submitted but the application submitted must be accepted.

If the application is rejected due to incomplete data or because a provider doesn’t meet Medicare standards, you will lose the retroactive billing date and must start the application process over. This is why it’s so critical to stay on top of the Medicare enrollment process and ensure your application is processed without any issues. If mailing anything to Medicare, be sure to send certified and keep a copy of the tracking certificate. If submitting through PECOS, make sure to get a tracking id and regularly check on the status.

Medicare Revalidation

Check Medicare revalidation by NPI to see listed due dates and source dates before you begin. No login required. Confirm current requirements with CMS or your Medicare Administrative Contractor.

How often do you need to revalidate Medicare?

Medicare providers and suppliers generally revalidate their enrollment every five years; DMEPOS suppliers generally revalidate every three years. CMS can also request an off-cycle revalidation. See CMS revalidation guidance for current requirements.

How do I revalidate Medicare?

You can revalidate through PECOS or use the applicable paper application. PECOS lets you review your existing record, upload supporting documents and sign electronically. PPS can help prepare and submit your revalidation; that assistance uses the same Medicare enrollment channels.

What are the risks if I fail to revalidate?

Missing a required revalidation can lead to deactivation of Medicare billing privileges and a gap in payment. Follow your contractor’s notice and respond by the applicable deadline.

Is my enrollment record due for revalidation?

Check the CMS Medicare Revalidation List and any notice from your contractor for your due date. Follow current CMS instructions rather than relying on a previous deadline or an old grace period.

Completing a PECOS Application

We recommend PECOS for applications supported by the system. It provides an online way to prepare, submit and track Medicare enrollment applications. Processing times vary, so monitor your submission and respond promptly to requests from your Medicare Administrative Contractor.

PECOS includes checks that help identify missing information. Review the provider, organization, NPI and location details carefully before submission; automated checks do not replace a complete application review.

For more information on PECOS or to complete a Medicare application using their system, visit their website at: https://pecos.cms.hhs.gov/pecos/login.do

We have provided a very helpful article on completing your PECOS Medicare application here.

CMS Fee Schedule Tool

Do you know what each office visit or procedure is paying you?

How much more does a 99203 pay than a 99213?

This valuable fee schedule tool provided by CMS will tell you how much each code is paying currently and how much they have paid historically. Many of your insurance contracts are based on prior year Medicare fee schedules so it is vital that you are equipped with this knowledge.
