How long does it take to switch medical billing companies?

A well-planned transition takes 6-10 weeks from signing with a new billing company to full cutover. Rushing it under 4 weeks increases the risk of missed claims and payment gaps. Budget 90 days total including the AR rundown period.

Will switching billing companies disrupt my revenue?

If done correctly with an overlap period, disruption is minimal. The key is to have the new biller taking over new claims before the old biller is terminated, so there is no gap in claim submission. Most practices see temporary softness in collections in weeks 3-6, then a rebound as the new biller's claims start paying.

Do I need to notify my payers when switching billing companies?

Yes, and this step is often overlooked. Medicare, Medicaid, and most commercial payers require a formal change-of-billing-representative notification. Without it, payments can be rejected or delayed for 30-90 days. Your new billing company should handle these notifications as part of their onboarding.

What happens to my outstanding AR when I switch?

You have three options: (1) Keep the old biller working the AR on a reduced retainer until it is collected, (2) Transfer the AR to the new biller who will work it on a contingency basis, or (3) Write off old AR over 120 days. Most practices use option 1 for AR under 90 days and option 2 or 3 for older balances. Medtransic handles AR transitions as part of our onboarding process.

Can I switch billing companies mid-year?

Yes, you can switch any time. Mid-year transitions are actually common because practices often hit a breaking point and can't wait for a calendar year restart. The key documents you need regardless of timing are a full AR aging report, claim history export, and outstanding denial log.

How do I evaluate a new medical billing company before switching?

Ask for references from practices in your specialty, request their first-pass claim acceptance rate, denial rate, and average days in AR. Ask whether they assign a dedicated account manager, and review the contract for auto-renewal clauses and data ownership terms. Any reputable biller should provide this information freely.

How to Switch Medical Billing Companies

The law is on your side on the part that worries people most. Under 45 CFR 164.504(e)(2)(ii)(J), at the termination of a business associate contract your billing company must return or destroy all protected health information it holds for you and retain no copies - so your data is not leverage it can hold over the transition.

Most practices can switch billing companies in days, not months. The long timelines you read about assume your data has to move and your systems have to be rebuilt, and usually neither is true. If your practice owns its software and its clearinghouse account, a new team simply gets a login - only the people working your claims change.

What Actually Changes When You Switch

Your software - stays. The billing company works inside the systems you already use.
Your data - stays. It was never in the billing company's possession; they had a login.
Your clearinghouse account - stays. Nothing to re-enrol, and remittances keep arriving where they do today.
Your staff's routine - stays. No new software to learn, no change at the front desk.
Who works your claims - this is the part that changes.
Your outstanding balances - these need an owner. It is the one step that genuinely matters.

Which Situation Are You In?

One question decides whether switching is simple or genuinely hard: who owns the practice management system?

You own your system - the common case

The billing company had a user account on software you pay for. There is nothing to export, because the data is already yours and already where it lives. The new team gets its own login, often within the same week.

Your billing company supplies the software

Some billing companies bundle the practice management system as part of the service. Here the data really does sit in their platform, and you need a full export before you give notice. Plan for a slower, more careful transition and get the export terms in writing.

The Six Steps

Step 1: Check who owns your system

Start here, because this answer sets the whole timeline. Confirm that the practice - not the biller - owns the system login and the clearinghouse account, and that you can add and remove users yourself. Check your current contract for its notice period and any automatic renewal.

Step 2: Add the new biller as a user

You do not hand over your system - you add a login to it, limited to billing functions, while the owner account stays in the practice's name. You can revoke that access at any time. There is no migration project, because nothing is being migrated.

Step 3: Agree the cutover date

Pick the day the new team starts submitting, and put in writing who works the claims filed before it. Keep the outgoing biller's access until the handoff is confirmed. For most practices nothing changes at the front desk.

Step 4: Payer updates - only if something changes

This is the step most guides overstate. Payers care about your provider identifiers and where the money goes, not about who keys in the claim - so if those are unchanged, most need nothing at all. Updates are only required when something on their record actually changes, such as your remit address or banking details.

Step 5: Hand off the outstanding balances

Everything billed before the switch and not yet paid needs an owner. List what is billed, what is paid and what is still open, then decide who chases the rest and get it in writing. Do not write off aged balances by default - some are still collectible and should be reviewed first.

Step 6: Watch the first month

A switch is working when claims go out on time and payments land where they should. Confirm the first claims were accepted, check payments are posting to the right accounts, and compare claim counts against your actual visit volume. Keep one named contact for anything that stalls.

What You Should Not Have to Do

Export years of history before giving notice - not if the data is already in your own system.
Re-credential anything with your software - adding a user is not credentialing. It takes minutes.
Set up a new clearinghouse - your existing account carries on.
Retrain your staff - the billing company adapts to your workflow, not the reverse.
Write off older balances to simplify the handover - that is lost revenue, not tidiness.

What the First 90 Days Look Like

Week 1-2: getting started

The new team has a login to your existing system and the cutover date is agreed in writing. New claims start going out. Ownership of pre-cutover balances is settled before anyone stops working.

Week 3-6: finding the rhythm

A full billing cycle has run end to end and payments are posting to the right accounts. Older balances are being actively worked. Claim counts should line up with your visit volume.

By day 90: fully settled

Collections are steady against your own prior baseline and the pre-cutover balances are resolved or on a clear plan. Final reconciliation with the previous biller is done, and their access to your system is removed.

8 Red Flags That Signal It's Time to Switch Billing Companies

Denial rate consistently above 10% with no improvement trend
Days in AR exceeding 45 days (benchmark is 30-35 for most specialties)
Vague or delayed reporting - you cannot see your own denial reasons in real time
High staff turnover at your billing company with no assigned account manager
Repeated write-offs of claims that were still within timely filing limits
No proactive payer contract renegotiation or fee schedule review
Lack of specialty-specific expertise for your practice type
Collections flat or declining despite growing patient volume

Frequently Asked Questions - Switching Billing Companies

How long does it really take?

If you own your system and your clearinghouse account, a new team can start working your claims within days. What takes longer is the tail - balances billed before the switch still have to be collected, usually over a further one to three months. Those are two different clocks, and most guides confuse them.

Do I have to export and move all my data?

Usually not. If the practice owns the system, the data never belonged to the billing company - they simply had a login, and the new team gets its own. The exception is a billing company that supplies your software, in which case you do need a proper export before giving notice.

Will my staff have to learn new software?

No. The billing company works inside the systems you already use, so your front desk and clinical workflow stay as they are. A billing partner that asks you to move onto their platform is adding a software migration on top of a billing change.

Do I need a new clearinghouse account?

Not if you already have one. Medtransic submits through the practice's existing clearinghouse account, so there is nothing to re-enrol and your electronic remittances keep arriving exactly where they do today.

Do I have to notify my payers?

Usually not. If your provider identifiers and payment details are unchanged, most payers need nothing. Updates are only required when something on their record actually changes, such as your remit address or banking details.

What happens to the money I am already owed?

It gets worked. Everything billed before the switch should be listed, assigned an owner and followed up. The common advice to write off older balances is how practices lose real money - some of it is still collectible.

What if my current billing company will not cooperate?

This is the honest variable. The pace of the handover partly depends on how the outgoing company behaves, though it matters far less when you own your system. Talk to us about your situation.
