TL;DR: Billing problems cost therapy practices $15,000 to $35,000 monthly through denied claims, underpayments, and lack of follow-up. Audit your billing by checking your aging report, denial rate, payment accuracy, time to payment, and eligibility verification. If your biller can’t give you straight answers, your aging report keeps growing, or you’re doing billing work yourself, you need a change. Good billing means proactive communication, systematic follow-up, clean claims, and transparent reporting.
You’re seeing clients. You’re doing the work. But your bank account doesn’t reflect the hours you’ve put in.
Before you blame the market or your rates, we need to talk about something most therapy practice owners overlook: your billing process.
Here’s what we see all the time. A therapist comes to us frustrated about cash flow. They think they need more clients or higher fees. Then we look at their billing, and we find thousands of dollars sitting in denied claims that nobody followed up on. Or payments that came in $20 short, and nobody noticed. Or claims that were never submitted in the first place.
The numbers tell the story. Small billing inefficiencies compound into $15,000 to $35,000 in monthly losses for therapy practices. That’s not a typo. That’s real money walking out the door because of billing problems.
Is your biller costing therapy practice money? And more importantly, what do you do about it?
The Real Cost of Billing Problems
Let’s start with what billing problems actually look like in your practice.
You might think a billing problem means claims aren’t getting submitted. That happens, but it’s usually more subtle. The claim gets submitted, but it gets denied. Then it sits there. Nobody appeals it. Nobody follows up. The insurance company keeps your money, and you move on to next week’s sessions.
Or the claim gets paid, but it’s $30 less than your contracted rate. Your biller doesn’t catch it. You don’t catch it. Multiply that by 20 clients per week, and you’re losing $600 weekly without realizing it.
Here’s the scope of the problem. Behavioral health denial rates hit 16% to 22% in 2026. That’s significantly higher than other medical specialties. Mental health claim denials occur at rates 85% higher than comparable medical claims.
Think about that. If you see 40 clients weekly and bill insurance for all of them, somewhere between 6 and 9 of those claims will get denied. Every single week.
The question isn’t whether you have billing problems. The question is whether someone is actually fixing them.
How to Audit Your Current Billing Process
You need to know what’s actually happening with your claims. Here’s how to find out.
Step 1: Pull Your Aging Report
An aging report shows you which claims haven’t been paid and how long they’ve been sitting there. Your practice management software should have this report. If you’re using SimplePractice, TherapyNotes, or any major platform, you can generate this in about two minutes.
Look for claims older than 30 days. These should have been followed up on already. If you see claims sitting at 60, 90, or 120 days, that’s a red flag. Someone isn’t doing their job.
Let’s look at an example. You pull your aging report and find $8,000 in claims over 60 days old. Half of those are denials that were never appealed. The other half are claims that show as “pending” in your system, but when you call the insurance company, they have no record of receiving them.
That $8,000 isn’t theoretical. It’s money you already earned. Your biller just didn’t collect it.
Step 2: Check Your Denial Rate
You need to know what percentage of your claims get denied. Take the number of denied claims last month and divide it by the total number of claims you submitted. Multiply by 100.
If your denial rate is above 5%, you have a problem. If it’s above 10%, you have a serious problem.
But here’s the thing. The denial rate alone doesn’t tell you everything. You also need to know what happens to those denials. Over 70% of mental health denials that reach the appeals process get overturned. If your biller isn’t appealing denials, you’re leaving money on the table.
Ask your biller: What percentage of denials do you appeal? How many of those appeals succeed? If they can’t answer those questions, that tells you something.
Step 3: Review Payment Accuracy
Pull your explanation of benefits (EOB) reports for the last three months. Compare what the insurance company paid to what they should have paid based on your contracted rate.
You’re looking for underpayments. These happen more often than you think. The insurance company pays you $85 for a session when your contracted rate is $95. It’s a small difference, but it adds up.
Your biller should catch these automatically. If they don’t, you’re losing money every single week.
Step 4: Track Time to Payment
How long does it take for a claim to get paid after you submit it? The standard is 14 to 30 days for most insurance companies. If you’re consistently seeing 45, 60, or 90 days, something is wrong.
Either your claims have errors that slow down processing, or your biller isn’t submitting them promptly. Both problems hurt your cash flow.
Calculate your average days in accounts receivable. Add up the total amount owed to you in unpaid claims. Divide that by your average daily revenue. If that number is above 30, your billing process needs work.
Step 5: Verify Eligibility Checks
Eligibility issues account for 22% of preventable denials in behavioral health. That means someone scheduled a client, saw them for a session, and then discovered their insurance wasn’t active.
Your biller should verify insurance eligibility before every appointment. Not just new clients. Every appointment. Insurance coverage changes. People switch jobs. Plans get canceled.
Ask your biller: When do you verify eligibility? What happens if coverage isn’t active? If the answer is anything other than “before every appointment,” you’re at risk.
Red Flags Your Biller Isn’t Working Out
Now you know how to audit your billing. Here are the warning signs that your current biller isn’t cutting it.
You Can’t Get Straight Answers
You ask about a denied claim. Your biller gives you a vague answer about “working on it” or “waiting to hear back.” You ask again two weeks later. Same answer.
Good billers track everything. They know which claims are pending, which are denied, which are in appeal, and what the next step is for each one. If your biller can’t tell you the status of a specific claim in under two minutes, that’s a problem.
Your Aging Report Keeps Growing
You have more old claims each month instead of fewer. That means claims are piling up faster than they’re getting resolved.
This happens when your biller focuses on submitting new claims but ignores follow-up. They’re doing half the job.
You’re Doing Billing Work
You find yourself calling insurance companies. You’re the one checking on denied claims. You’re following up on missing payments.
If you’re paying someone to do billing, you shouldn’t be doing any billing. Your job is seeing clients and running your practice. When you spend 30 minutes on the phone with Aetna, that’s 30 minutes you’re not seeing a client. That costs you money twice.
Clients Complain About Billing Issues
Clients tell you they got bills for sessions that should have been covered. Or their insurance company says you never submitted a claim. Or they’re getting collection notices for balances they don’t owe.
These complaints point to errors in your billing process. Maybe claims aren’t getting submitted. Maybe they’re being submitted with the wrong information. Either way, your biller is creating problems instead of solving them.
You Don’t Understand Your Reports
Your biller sends you reports, but you can’t make sense of them. Or worse, they don’t send you reports at all.
You need clear, regular reporting. At minimum, you should get a monthly summary that shows: total claims submitted, total collected, denial rate, outstanding balance by age, and any issues that need your attention.
If you can’t understand your reports, you can’t manage your practice finances. If you’re not getting reports, you’re flying blind.
What Good Billing Actually Looks Like
You’ve identified problems. Now you need to know what to expect from a competent biller.
Proactive Communication
Good billers don’t wait for you to ask questions. They tell you about problems before you discover them. They send you regular updates. They flag issues that need your decision.
They also communicate with clients. When there’s a billing issue, they handle it. They explain benefits. They set up payment plans. They answer questions. You shouldn’t hear about billing problems from your clients.
Systematic Follow-Up
Every denied claim gets appealed unless there’s a clear reason not to. Every pending claim gets followed up on at specific intervals. Every underpayment gets corrected.
This happens systematically, not randomly. Your biller has a process. They track deadlines. They know what needs attention each day.
Clean Claims
Claims get submitted the first time correctly. That means right codes, right modifiers, right client information, right dates. When claims are clean, they get paid faster and are denied less.
Your denial rate should be under 5%. If your biller is submitting clean claims and following up properly, that’s achievable.
Transparent Reporting
You get reports you can actually use. You can see what’s working and what isn’t. You can make informed decisions about your practice.
You also get answers when you ask questions. Your biller can pull up any claim and tell you exactly where it stands.
Your Next Steps
You’ve done the audit. You’ve found problems. Now what?
Start with a conversation. Show your biller what you found. Give them a chance to explain and improve. Sometimes billing problems come from a lack of training or unclear expectations. You might be able to fix this with better systems and communication.
Set clear metrics. Tell your biller what you expect. Denial rate under 5%. All claims over 30 days are followed up on weekly. All denials appealed within 15 days. Monthly reports by the 5th of each month.
Give them 30 days to improve. Then audit again. If the numbers get better, great. If they don’t, you need a new solution.
You have options. You can hire a different billing person or company. You can bring billing in-house if you have the bandwidth. You can switch to a cash-pay model if insurance billing is more trouble than it’s worth.
But you can’t keep losing money to billing problems. The numbers are too big to ignore.
When to Get Professional Help
Some billing problems are beyond fixing with a new biller. If your practice has grown past a certain point, you need more than just someone submitting claims.
You need financial systems. You need someone tracking your revenue cycle. You need someone who understands the tax implications of different billing arrangements. You need someone who can tell you whether your cash flow problems are actually billing problems or something else entirely.
That’s where accounting comes in. We work with therapy practices every day. We see the billing problems. We also see the bookkeeping problems, the tax problems, and the cash flow problems. Sometimes they’re all connected.
If you’re not sure whether your biller is the real issue, let’s talk.
We can look at your numbers and tell you exactly where the money is going. We can help you figure out whether you need a new biller, better systems, or a completely different approach to managing your practice finances.
Your billing process should put money in your bank account, not leave it sitting with insurance companies. If that’s not happening, it’s time to fix it.
TL;DR: Billing problems cost therapy practices $15,000 to $35,000 monthly through denied claims, underpayments, and a lack of follow-up. Audit your billing by checking your aging report, denial rate, payment accuracy, time to payment, and eligibility verification. If your biller can’t give you straight answers, your aging report keeps growing, or you’re doing billing work yourself, you need a change.
