The biggest reason practices stay with a billing company they’re unhappy with isn’t loyalty. It’s fear of the switch. What happens to claims in progress? Who works the old AR? Will cash stop for a month?
Those fears are reasonable. A badly planned switch can leave a gap where nobody submits, nobody follows up, and deposits drop. A well-planned one is barely noticeable. The difference is sequence.
Step 1: Read your current contract first
Before you tell anyone, check three clauses:
- Notice period. Often 30 to 90 days.
- Runout terms. Whether the current company will keep working claims it already submitted, for how long, and at what fee.
- Data and access return. How and when your data, reports and system access come back to you.
Knowing these tells you your real timeline.
Step 2: Decide who owns the old AR
This is the most important decision in the switch. There are two common options:
- The outgoing company works its runout. It keeps following up on claims it submitted before the cutover, usually for 60 to 120 days. Clear, but you depend on a company you’re leaving.
- The new company takes over the open AR. One team owns everything, but it needs full claim history and access from day one.
Either can work. What fails is leaving it undefined. Write down which claims belong to whom, by date of service or submission date.
Step 3: Make sure you own your accounts
Many practices discover mid-switch that the billing company set up the clearinghouse, payer portals or ERA enrollment under its own login. Confirm that your practice holds admin access to:
- Your practice management or EHR system
- Your clearinghouse account
- Payer portals (Availity, payer-specific portals, Medicare)
- ERA (835) and EFT enrollments
Transferring existing admin access to your practice is usually faster than re-registering from scratch.
Step 4: Set up the new company’s access and enrollments early
Your new team needs user accounts in your systems, clearinghouse access, and any payer enrollments completed before cutover. EDI setup can be quick. ERA enrollment can take weeks, so start early. Payments still arrive without ERAs; posting is just slower.
Step 5: Pick a clean cutover date
Choose a specific date. Claims for services from that date forward go to the new team. Everything before follows your Step 2 decision. A month-start date keeps reporting clean.
Step 6: Run a short overlap
For the first 1 to 2 weeks, have the new team work alongside the old process: verifying eligibility, cleaning the claim queue, and reviewing open denials. This catches gaps before they cost money.
Step 7: Watch three numbers for 60 days
- Claims submitted per week against your normal volume. A drop means something is stuck.
- Weekly deposits against your average. A dip in weeks 3 to 6 is the classic sign of a gap.
- Rejections at the clearinghouse. Setup errors show up here first.
A realistic timeline
| Week | What happens |
|---|---|
| Week 0 | Contract review, notice given, AR ownership decided |
| Weeks 1 to 2 | Access, clearinghouse and payer setup for the new team; ERA enrollment started |
| Week 3 | Cutover date; new claims go to the new team |
| Weeks 3 to 5 | Overlap and queue cleanup |
| Weeks 3 to 12 | Watch submissions, deposits and rejections weekly |
How DrBillerz handles a switch
We’ve taken over billing mid-stream from incumbent companies, including ambulance and EMS agencies, without interrupting claim flow. We start with a baseline of your volume, collections and payers, set up EDI and clearinghouse access, and agree in writing who owns the old AR before cutover.
From day one, you see the new work in our client portal: claims submitted, denials worked and payments posted, so you can confirm cash is flowing instead of hoping. Billers start from $7 an hour, and the first 4 weeks are a free pilot with no contract.

FAQ
How long does it take to switch medical billing companies?
Usually 3 to 6 weeks from notice to cutover, depending on your contract’s notice period and how quickly access and enrollments can be set up. ERA enrollment can take longer but doesn’t stop payments.
What happens to my AR when I switch billing companies?
Either the outgoing company works its runout on claims it submitted, or the new company takes over all open AR. Decide in writing before cutover, with a clear dividing line by date.
Will my cash flow drop when I change billing companies?
Not if the switch is sequenced well. Watch weekly claim submissions and deposits for 60 days, and run a short overlap so gaps are caught early.
Do I own my clearinghouse and payer portal accounts?
You should. Confirm your practice holds admin access to your clearinghouse, payer portals and ERA/EFT enrollments before giving notice.
