A dermatologist wrote about it publicly in Practical Dermatology. His billing company had made errors that cost him thousands of dollars. Customer service was poor. Mistakes kept coming that were not his fault. He knew he had to change.
The problem was how. The company required a minimum 60-day notice, which meant paying it for at least 60 more days. Worse, getting his patient financial records, data, and balances transferred over looked like a nightmare. The accounts receivable alone would be a nightmare to transfer.
So he prepared quietly. He stopped sending the company new patient bills. He gathered everything he needed before giving notice. When he finally terminated, the company demanded a fee equal to 60 days of billing, over $20,000. He refused, because he had scratched that clause out of the contract before signing it, and because the company had breached its obligations. He got out.
Most practices are not that prepared. That is why the transition fear keeps bad vendor relationships alive for years. A practice stays with a billing company it knows is underperforming because switching feels riskier than staying.
It does not have to be. Switching medical billing companies does not cost revenue when you run the exit as a process. It costs revenue when you treat it as a phone call. This article gives you the process: the preparation, the timeline, the data checklist, the contract traps, and the dual operations mechanics that keep every claim tracked to closure.
Why Practices Switch (The 4 Triggers)
Practices rarely switch over one bad month. They switch when a pattern becomes undeniable. These are the four triggers that push a practice from unhappy to leaving.
Revenue leakage you can measure
Your denial rate climbs above 5%. Days in AR push past 40 or 50. Net collection rate drops below 95%. These are not feelings, they are numbers, and when they move the wrong way for two consecutive months, the vendor is not having a bad stretch. The vendor is the problem. Our buyer’s guide sets out the KPI benchmarks every vendor should meet, and if your current vendor misses them quarter after quarter, you already have your answer.
Communication breakdown
No named account manager. Days to get a response. No explanation for denials. Reports that arrive late, or not at all. A practice cannot audit what it cannot see, and a vendor that hides behind vague reporting is a vendor that does not want to be measured.
Denials piling up unworked
Appeals not filed. Denial worklists not shared. The same denial reasons repeating month after month with no root-cause work. When denials sit untouched, they age past appeal windows and become write-offs. That is revenue your practice earned and will never collect. Our denial management guide explains what a real denial process looks like, and it is not “we handle denials.”
Contract and cost surprises
Hidden fees surfacing that were not in the original quote: statement fees, appeal fees, credentialing fees. Rate increases without discussion. A renewal that locked you into another term without anyone flagging it. Our outsourcing cost guide breaks down what billing companies actually charge and which fees are legitimate versus which are padding.
If two or more of these are true for your practice, you are not “thinking about switching.” You have already decided. The rest of this article is the how.
The Cost of Staying (Why Waiting Is Not Free)
Practices delay switching because the switch feels expensive. The delay is what is actually expensive.
Consider a practice collecting $100,000 per month with a net collection rate of 90% when it should be 95%. That 5-point gap is $5,000 per month, $60,000 per year, walking out the door. A denial rate of 12% when it should be under 5% means roughly 7% of claims need rework or write off, and every month those denials age, a portion passes timely filing limits and becomes unrecoverable. Days in AR at 55 instead of 35 means 20 extra days of earned revenue sitting unpaid, which is a cash-flow loan the practice is giving payers for free.
None of this shows up as a single dramatic loss. It shows up as a slightly worse month, every month, for years. The transition fear keeps that slow bleed going because the cost of switching feels concrete (a notice period, an overlap month, a learning curve) while the cost of staying feels abstract (a percentage here, a delay there).
Run the math on your own numbers before you decide to wait. Take your monthly collections, your denial rate, your days in AR, and your net collection rate, and compare them against the benchmarks in our buyer’s guide. The gap between your numbers and the benchmarks, multiplied by 12 months, is what waiting costs. In most cases, it dwarfs the cost of a structured transition.
The dermatologist in the Practical Dermatology case stayed too long because leaving felt hard. By the time he left, the billing errors had already cost him thousands. The switch was not the expensive part. The years before the switch were.
Before You Give Notice: The Quiet Preparation Phase
Do not give notice first. Prepare first. This is the section most switching guides skip, and it is the section that determines whether your exit is clean or chaotic.
Audit your current numbers
Pull your denial rate, days in AR, net collection rate, and aging buckets from your own practice management system or your most recent reports. You need a baseline to compare the new vendor against, and you need it before the outgoing vendor knows you are leaving. Once notice is given, access to reports has a way of slowing down.
Secure your data independently
Export or screenshot every report you can access right now: AR aging, denial reports, payment histories, payer enrollments. Do not rely on the outgoing vendor to provide these after notice. The time to secure your data is while you still have full access.
Read your current contract line by line
Find five things: the termination notice period, whether termination is for cause or for convenience, the early termination fee formula, the auto-renewal date, and whether there is a data return clause or a transition assistance clause at all. Note the auto-renewal date specifically. If it falls within 90 days, timing your notice around it matters enormously. Missing an auto-renewal window can lock you into another full term.
Line up the new vendor before notice
The new vendor should be selected, contracted, and ready to start credentialing and data migration before the old vendor hears about it. This is not deceptive. It is prudent sequencing. A gap between vendors is where revenue is lost, and the way to avoid a gap is to overlap, not to quit and then start shopping.
The 90-Day Transition Timeline
A structured switch runs in three phases over roughly 90 days. The 90-day frame is a planning frame, not a promise. Some transitions complete in 60 days. Complex multi-payer or multi-location practices may need the full 90. The sequence matters more than the exact day count.
Phase 1: Days 1-30 (Preparation and Overlap Setup)
The new vendor is selected and contracted, and a Business Associate Agreement is signed before any patient data changes hands. Credentialing and payer enrollment for the new vendor begins now, before the old arrangement ends, so there is no coverage gap on claim submission. A written data export request goes to the outgoing vendor with a specified format and deadline (see the data exit section below). Staff are briefed: who handles what during transition, who the new contact is, and what changes for front desk and providers. Ideally, nothing changes for providers. They keep seeing patients and documenting care. The billing change happens behind the scenes.
Phase 2: Days 30-60 (Parallel Operations)
The new vendor begins submitting new claims. The outgoing vendor continues working existing AR and the claims it already submitted. Every open claim is reconciled daily or weekly so no claim is owned by nobody. Active prior authorizations are transferred and acknowledged by the new team. Authorization gaps are the number one transition revenue risk: a claim submitted without a valid authorization is a denial waiting to happen, and authorizations tied to the old vendor do not automatically carry over.
Phase 3: Days 60-90 (Cutover and Verification)
Old AR ownership is finalized. Claims under 90 days typically transition to the new vendor for follow-up. Older claims get targeted recovery before or during transition. KPI reviews happen at 30, 60, and 90 days: clean claim rate, denial rate, days in AR, cash collections, and outstanding AR balance, all compared against the baseline you captured before notice. Old vendor access is revoked only after all data is confirmed received and verified. Never revoke access on a calendar date alone. Revoke it when the data is in hand and checked.
Data Exit: What to Demand, in What Format, by When
This is where most switching guides fail. They say “get your data” and stop. That advice is useless without specifics, because “your data” can arrive as an unusable PDF dump, a proprietary file your new vendor cannot import, or nothing at all.
Your data belongs to you. Any contract that does not say this explicitly is a red flag for your next agreement. But even with the right clause, you need to demand the right items, in the right format, by a deadline.
| Data item | Why you need it | Format to demand | Timing to demand |
|---|---|---|---|
| Complete claims history (submitted, paid, denied, pending) | The new vendor cannot work what it cannot see | CSV or 837/835-compatible export | Within 30 days of termination |
| AR aging report by payer and bucket | Defines who owns which claims during transition | CSV or Excel, bucketed 0-30, 31-60, 61-90, 90+ | Before notice, and updated at cutover |
| Payer enrollment and credentialing records | Prevents submission gaps under the new vendor | Copies of enrollment confirmations and EDI enrollment IDs | Before new vendor credentialing begins |
| EDI and clearinghouse reports | Proves what was submitted and accepted | Clearinghouse reports or 277CA acknowledgments | Within 30 days |
| Denial worklists and appeal histories | Prevents rework and missed appeal deadlines | CSV with CARC/RARC codes and appeal status | Before cutover |
| Fee schedules and payer contracts | The new vendor needs contracted rates to catch underpayments | PDF copies | Before new vendor onboarding |
| Patient balance and statement history | Prevents duplicate patient billing during transition | CSV or PM system export | At cutover |
| ERA/EOB remittance history | Needed for payment posting reconciliation | 835 files or PDF | Within 30 days |
Three rules govern all of this. First, demand the format in writing. “We will provide your data” without a format is meaningless if it arrives in a form nobody can use. Second, demand a deadline. Thirty days from termination is the standard to push for. Without a deadline, “soon” stretches indefinitely. Third, back up independently. Export what you can access before giving notice and do not rely solely on either vendor. If the outgoing vendor charges an export fee, that fee should have been stated in the original contract. A surprise export fee is itself evidence of a trap contract.
Termination Clauses to Watch (The Traps)
Read these before you sign your next contract, and check your current contract against them before you give notice. Each one has cost a real practice real money.
The 60-day notice trap. A 60-day notice period means 60 more days of paying a vendor you want to leave. It is common enough that you should plan for it, but it should never come as a surprise. The dermatologist in the Practical Dermatology case knew about his 60-day clause and prepared around it. Most practices discover it when they try to leave.
The termination fee formula. Some contracts charge a flat fee. Worse ones charge “remaining contract value,” meaning all monthly fees for the rest of the term. For a small practice, this can be tens of thousands of dollars. The Practical Dermatology case involved a demand for over $20,000, equal to 60 days of billing. Always calculate the total exit cost before giving notice, not after.
Auto-renewal without notice. Contracts that renew for another 12 to 24 months unless you give notice 90 days before the renewal date. Miss the window and you are locked in again. Calendar the renewal date the day you sign any vendor contract. This single habit prevents more trapped renewals than any other.
Termination for cause versus for convenience. Termination for cause means the vendor breached the agreement or missed agreed KPIs. It usually carries no penalty, but it requires documentation and usually a cure period (30 days is standard). Termination for convenience means you simply want to leave. It usually requires the notice period and may carry a fee. Know which one applies to your situation and document accordingly. If you are terminating for cause, build the documentation file before giving notice: missed KPI reports, unanswered communications, unworked denials.
No data return clause. If the contract says nothing about data return, the vendor has no contractual obligation to cooperate. This is the single most dangerous omission in a billing contract. A vendor that will not commit to returning your data in writing is telling you what will happen when you try to leave.
No transition assistance clause. Without a contractual requirement to cooperate with your successor for at least 60 days after termination, the outgoing vendor can simply stop responding. Open AR, denial worklists, and institutional knowledge walk out the door with them. Our buyer’s guide recommends demanding this clause in every new contract. This article shows you why: without it, switching means starting from zero on every open claim.
Clearinghouse lock-in. Some vendors require you to use their clearinghouse and will not commit to timely claims file delivery if you leave. Ask directly: “If I end this agreement, how exactly do I send my next day’s claims through a different system?” If the vendor cannot answer clearly, do not sign.
If your current contract has two or more of these traps, that is itself a reason to switch, and it is also a reason to get legal review before giving notice.
Running Dual Operations During Transition
Parallel operations sound simple: both vendors work at the same time. In practice, they fail without clear rules. Here are the mechanics.
The cutoff date. Pick a single date. Claims with dates of service before the cutoff stay with the outgoing vendor. Claims on or after the cutoff go to the new vendor. No exceptions, no gray zone. Every claim needs exactly one owner.
Who works old AR. The outgoing vendor works claims it submitted until they resolve or until the agreed transition period ends, whichever comes first. After that, unresolved old AR transfers to the new vendor with full documentation. Claims under 90 days typically transition cleanly. Older claims may need targeted recovery work, and that work should be scoped before transition, not discovered during it. Our AR aging guide explains how aging buckets work and why the 90+ day bucket needs special attention.
Avoiding duplicate submissions. The number one operational risk in dual operations is both vendors submitting the same claim. A duplicate submission creates a duplicate-claim denial on top of whatever else is happening with that claim. Prevent it with a shared claim log during overlap, a single source of truth for submission status, and a rule that only one vendor touches any given claim. If a claim’s ownership is unclear, it is not worked until ownership is clarified.
Patient communication. Patients should see no change. Statements continue, balances are consistent, and no patient receives duplicate bills. If a patient calls confused about a bill during transition, that is a transition failure, not a patient problem. The practice should have a single point of contact for billing questions throughout the overlap period.
Staff roles during overlap. Name who on the practice side owns the transition. Usually this is the administrator or office manager. Name the contact at each vendor. Set a meeting cadence: weekly during overlap is the minimum. The practice-side owner runs those meetings and holds both vendors to the cutoff date and the claim log.
When to end dual operations. Not on a calendar date alone. End it when three conditions are met: all old AR is either resolved or transferred with documentation, all authorizations are confirmed under the new vendor, and the first KPI review shows the new vendor meeting benchmarks. Ending dual operations early to save on overlap costs is how claims fall through cracks.
How Netix Onboards Switchers
Netix works inside your existing EHR. Kareo, AdvancedMD, eClinicalWorks, Athena, Office Ally: no software change, no migration, no retraining your staff on a new platform. For a practice switching vendors, this matters more than usual, because the last thing a transition needs is a second disruption layered on top of the vendor change.
Every engagement follows the Netix Revenue Recovery Process. It starts with a free practice audit. Netix reviews your denial rate, denial categories, appeal history, and AR aging, and you get a plain-numbers report in 48 to 72 hours, reviewed by a real billing specialist, showing what is recoverable and what is preventable. For a switching practice, this audit serves a second purpose: it gives you the baseline numbers to compare the new vendor against the old one, measured the same way.
From there, the process runs through clean claims setup, relentless follow-up on every open claim, and transparent reporting. Denial management, AR recovery, credentialing, and underpayment identification run as part of the broader revenue recovery work, not as separate engagements you have to coordinate.
If you are considering a switch, the audit is the right first step regardless of whether you hire Netix. It gives you the numbers you need to hold any vendor accountable, including your current one and including us. The audit is yours to keep whether you hire us or not.
Switching Checklist
Use this before, during, and after your switch:
- Baseline your numbers (denial rate, days in AR, net collection rate) before notice
- Export or screenshot all accessible reports independently
- Read your contract: notice period, termination fee, auto-renewal date, data clause, transition clause
- Select and contract the new vendor before giving notice
- Sign a Business Associate Agreement with the new vendor
- Request data export in writing with format and deadline specified
- Set a cutoff date for new versus old claims
- Transfer active authorizations and confirm acknowledgment
- Run parallel operations for 30 to 60 days minimum
- Reconcile every open claim weekly during overlap
- Review KPIs at 30, 60, and 90 days
- Revoke old vendor access only after data is verified received
Frequently Asked Questions
How long does it take to switch medical billing companies?
A full transition typically takes 60 to 90 days from decision to full cutover, including a 30 to 60 day parallel operations period. Credentialing the new vendor with payers should start before the old arrangement ends, so there is no gap in claim submission.
Will I lose revenue during the transition?
With a structured transition, revenue disruption should be minimal. The risk comes from unstructured switches: no cutoff date, no AR ownership plan, no authorization transfer. Parallel operations exist specifically to prevent gaps, and the KPI reviews at 30, 60, and 90 days exist to catch problems early.
Can I switch billing companies mid-contract?
It depends on your contract. Termination for cause, meaning documented vendor breach or missed KPIs, usually carries no penalty after a cure period of around 30 days. Termination for convenience usually requires the notice period and may carry a fee. Read the termination clause before acting, and document your grounds if you are terminating for cause.
Who owns my billing data when I leave a billing company?
Your practice owns its patient and billing data. Any contract should state this explicitly and require return in usable format within 30 days of termination at no charge. If your contract does not say this, that is a red flag for your next contract, and it is a reason to secure your data independently before giving notice.
What happens to my old accounts receivable when I switch?
Old AR should transfer to the new vendor or be worked by the outgoing vendor through an agreed transition period. Claims under 90 days typically transition to the new vendor for follow-up. Older claims may need targeted recovery. Every aging claim needs a named owner during transition, and no claim should sit without an owner at any point.
How much notice do I need to give my billing company?
Typically 30 to 90 days depending on the contract. Sixty days is common. The notice period is one reason to prepare quietly before giving notice: you want the new vendor ready before the clock starts, not scrambling after it.
Do I need to change my EHR or practice management system when switching?
No, not with Netix. Netix works inside your existing EHR, including Kareo, AdvancedMD, eClinicalWorks, Athena, and Office Ally. If a vendor requires migration, that is a cost and a risk to weigh, not a given.
What should I ask a new billing company about their transition process?
Ask: What is your parallel operations period? Who owns old AR during transition? How do you transfer authorizations? What is your KPI review schedule? What happens if the transition goes wrong? A vendor that cannot answer these specifically is not ready to onboard you. Our buyer’s guide gives you 15 questions to ask any vendor before signing.
