Credentials such as licenses, certifications and education verification belong to you and carry over. Payer enrollment does not: it is tied to a tax identification number and a service location, so joining a new practice requires new enrollment or a reassignment change with each payer.
Clinicians changing jobs consistently expect this to be quick because they were already credentialed. The distinction that matters is between credentials and enrollment.
What belongs to you
Licenses, DEA registration, board certification, education and training history, work history and malpractice history. These are yours and move with you.
The verification of them may also be reusable where it is recent enough to satisfy the payer’s standards.
What belongs to the practice
The enrollment. Payers enroll a provider at a location under a tax identification number, with a reassignment of benefits to that entity.
Change the entity and the arrangement has to be rebuilt, however well known you are to the payer.
The reassignment step
For Medicare, joining a group means reassigning your benefits to that group, which is a specific enrollment action.
It is also the step most often left incomplete, producing claims that process against the wrong entity or reject entirely.
Terminate the old ones
Enrollments left active under a former employer are a liability. Claims can be submitted under them, correspondence goes to the wrong place, and revalidation notices are missed.
Confirm each termination rather than assuming the former practice handled it.
Update your profile first
Your credentialing profile drives most commercial applications. Updating the practice information, addresses and attestation before applications go out prevents a round of avoidable rejections.
An out-of-date attestation stalls files silently.
Timing the start date
Applications should go in well before the first day, not after it. Practices that wait for a signed contract to begin enrollment guarantee a revenue gap.
Where a start date is fixed, ask each payer about its effective date policy so the schedule can be planned around it.
Hospital privileges are separate again
Privileging at a new facility is its own process, with its own committee, timeline and reference requirements.
It runs in parallel with payer enrollment and finishes on its own schedule.
Keep your own copies
Diplomas, certificates, license documents, malpractice certificates of insurance, and a complete work history with dates and gaps explained.
Your former employer’s credentialing file is not yours, and asking for it after you leave rarely goes well.
Expect it to take longer than you want
Two to four months per payer is normal. Starting early is the only variable you control, and it is the one that matters.
Everything else in this process is somebody else’s queue.
References follow you too
Peer references are required repeatedly, and colleagues move, retire and stop responding.
Keeping current contact details for three peers who know your clinical work is a small habit that removes a recurring bottleneck.
Tell the payers about the address change
Directory records, correspondence and revalidation notices all go to the address on file, and an old one silently swallows deadlines.
Updating every payer with the new practice address is part of the move, not an afterthought.
Common questions
- Do I have to be credentialed all over again?
- Verification of your credentials may be reused where recent, but each payer must add you under the new group’s tax identification number.
- How long does it take?
- Commonly two to four months per payer, though delegated groups can add you in weeks.
- What happens to my old enrollments?
- They should be terminated or updated. Leaving them active under a practice you have left creates real compliance exposure.
- Can I bill at the new practice while it processes?
- Only from the effective date each payer assigns, which may or may not be backdated.
- Does my CAQH profile transfer?
- Yes. The profile is yours, and updating it with the new practice information is one of the first steps.
