One of the biggest misconceptions about medical billing is that it’s just submitting claims.
I wish it were that simple.
By the time a claim actually reaches an insurance company, dozens of small steps have already happened behind the scenes. Miss one of them — even a small one — and you’re looking at delayed payments, denied claims, or hours spent untangling something that could have been avoided from the start.
After years working in medical billing and healthcare administration, the thing I’ve learned is that successful billing isn’t about working harder. It’s about having a consistent process you can follow every single time.
Whether you’re handling billing yourself or thinking about hiring someone, understanding the full workflow helps you spot problems early — before they turn into lost revenue. Here’s what it looks like from beginning to end.
If you’re newer to billing, start with the fundamentals.
Step 1: Schedule the Appointment
Most people don’t realize the billing process starts before the client ever walks through your door.
When someone calls to schedule, collect the right information from the beginning:
- Full legal name
- Date of birth
- Address and phone number
- Insurance company and member ID
- Subscriber information
- Referral source
Getting this right the first time saves a surprising amount of cleanup later. It seems basic, but skipping it creates headaches down the line.
Step 2: Verify Insurance Benefits
This is one of the most important steps in the entire workflow — and one of the most skipped.
Before the first appointment, verify:
- Active coverage
- Mental health benefits
- Copay, coinsurance, and deductible
- Out-of-pocket maximum
- Visit limits
- Prior authorization requirements
- Telehealth coverage
- Whether you’re in-network
And please, don’t just rely on the insurance card. Benefits change constantly. I’ve seen practices assume coverage was still active because the client had the same card from last year — only to find out the policy had lapsed or changed entirely. A quick verification call before the first session prevents a lot of pain later.
Step 3: Estimate the Patient’s Responsibility
Once you’ve verified benefits, let the client know what they should expect to pay. That might include a copay, a deductible, coinsurance, or a self-pay rate if their insurance doesn’t cover your services.
Having that conversation upfront — before anyone sits down on your couch — prevents awkward billing surprises later. Clients appreciate knowing what they’re walking into.
Step 4: Collect Intake Paperwork
Before treatment begins, make sure you have:
- Completed intake and consent forms
- HIPAA acknowledgment
- Your financial policy (signed)
- A copy of their insurance card and photo ID
- A credit card on file, if that’s part of your policy
Most EHR systems now let clients complete all of this online before their first appointment, which saves time for everyone.
Step 5: Provide the Session
This is the part you actually went to school for.
While you’re focused on your client, keep in mind that your documentation also has to support accurate billing later. Good clinical notes protect your practice and help justify medical necessity if records are ever requested by an insurance company.
Step 6: Complete Documentation
As soon as possible after the session, finish your progress note, confirm the diagnosis codes, select the correct CPT code, and verify the session length.
Waiting a few days might not feel like a big deal, but it increases the chance of missing details — and that can affect both your documentation quality and your billing accuracy.
Step 7: Create the Insurance Claim
Once documentation is done, the claim can be generated. If you’re using an EHR, a lot of this populates automatically, which is helpful.
Before you submit, double-check the basics:
- Patient demographics
- Insurance information
- CPT and diagnosis codes
- Provider NPI
- Date and place of service
- Any modifiers that apply
Small errors here are one of the most common causes of unnecessary rejections. A quick review before you hit submit is worth it.
Step 8: Submit the Claim
Most practices submit claims electronically through a clearinghouse, and that’s the way to go. Electronic claims are faster, easier to track, and less prone to processing delays than paper.
Many EHR platforms make this nearly automatic at this point.
Step 9: Monitor Claim Status
Submitting the claim is not the finish line.
Check regularly to make sure your claims are actually moving through the system. Watch for accepted, rejected, pending, and denied claims, as well as any requests for additional information. The sooner you catch a problem, the easier it usually is to fix.
Step 10: Post Insurance Payments
When payment comes in, record everything: what insurance paid, what the patient owes, any deductible or coinsurance applied, the contractual adjustment, and any appropriate write-offs.
Accurate payment posting keeps your financial picture clear and makes it much easier to track what’s still outstanding.
Step 11: Bill the Patient
Once insurance has processed the claim, send the patient statement promptly. The longer you wait, the harder collection gets.
If you can offer online payment, auto-pay, payment plans, or text-to-pay options, use them. Making it easy to pay makes a real difference in your collection rates.
Step 12: Follow Up on Unpaid Claims
This is honestly where most practices lose money — not from bad documentation or wrong codes, but from letting unpaid claims sit too long.
Don’t assume an unpaid claim will sort itself out. Build a routine around reviewing your aging reports every week. If a claim hasn’t moved within a reasonable timeframe, check the status, correct any errors, appeal if it was denied, and call the payer if you need to.
Consistent follow-up is the difference between getting paid and writing off the balance.
Step 13: Review Your Reports
At least once a month, pull your key reports: accounts receivable aging, outstanding claims, collection rate, days in A/R, claims by payer, and patient balances.
These numbers tell a story. If something’s trending in the wrong direction, you want to catch it early — not six months later when it’s much harder to fix.
Where Billing Usually Breaks Down
In my experience, billing problems rarely come from one big mistake. They come from several small ones stacking up over time.
The most common culprits:
- Insurance wasn’t verified before the first session
- Documentation sat unfinished for too long
- The wrong CPT code got selected
- Claims went unsubmitted for weeks
- Denials were never appealed
- Patient balances weren’t collected at the time of service
- Aging reports weren’t reviewed regularly
None of these are hard to fix on their own. The challenge is staying consistent — especially when you’re also trying to run a full caseload.
How Technology Can Help
The right tools can take a lot of this off your plate. Eligibility verification, appointment reminders, electronic claim submission, payment posting, patient statements, and billing reports can all be automated to varying degrees.
Automation won’t replace good billing habits — but it does reduce the repetitive manual work and lowers the chance of things slipping through the cracks.
A Simple Follow-Up SOP for Solo Providers
Knowing you should follow up on unpaid claims and actually having a routine for it are two very different things. When you’re also the one seeing clients, writing notes, and answering your own phone, follow-up is usually the first thing that slips.
The good news is that it doesn’t need to be complicated. It just needs to happen on a schedule. Here’s a simple structure I recommend to solo providers who don’t have a billing staff to lean on.
Set a weekly time block.
Pick one day and a set amount of time — even 30 minutes on a Friday afternoon works — and treat it like an appointment with yourself. This is the single biggest factor in whether follow-up actually happens. If it’s not on the calendar, it gets pushed to “whenever I have time,” which usually means never.
During that block, run your aging report.
Most EHRs can sort outstanding claims by how long they’ve been unpaid. Pull that list every week, not just when something feels off. The point is to catch problems early, while they’re still easy to fix.
Then work the claims based on how old they are:
- 0–15 days: Don’t worry about these yet. Most claims are still processing normally at this stage.
- 16–30 days: Check the status. If it’s still pending with no issues, leave it. If it’s been rejected or denied, this is when you want to catch it and start working it.
- 31–45 days: This is your action window. If a claim hasn’t moved, call the payer. Confirm what’s holding it up, correct any errors, and resubmit if needed. Don’t let these sit untouched for another week — the longer a claim stalls here, the harder it gets to resolve.
- 46–60 days: Anything still unresolved at this point needs a phone call, not just a portal check. Get a representative on the line, ask directly what’s needed to finalize the claim, and document everything from the call — who you spoke with, what they told you, and any reference number.
- 60+ days: Treat these as priority. Most payers have a timely filing limit, and the closer you get to it, the more urgency this deserves. If a claim has been denied and you haven’t appealed it yet, this is the week to do it.
Keep a simple follow-up log.
It doesn’t need to be fancy — a spreadsheet or a note in your EHR works fine. For each claim you work, jot down the date, who you spoke with, what was said, and what the next step is. This matters more than people expect. If a claim ends up needing an appeal, you’ll be glad you have a paper trail instead of trying to remember a phone call from three weeks ago.
Close the loop.
At the end of each week’s session, you should be able to say one of three things about every claim on your aging report: it’s resolved, it’s actively being worked, or it’s been escalated (appealed, payer called, etc.). Nothing should just sit there unattended for another week without you knowing why.
Review the bigger picture monthly.
Weekly follow-up handles individual claims. Once a month, step back and look at trends — are denials clustering around a certain payer? A certain CPT code? A particular front desk error? Patterns like these tell you where to tighten your process so you’re not fixing the same problem over and over.
This kind of routine isn’t glamorous, and it won’t feel urgent in the weeks when everything’s going smoothly. But it’s exactly what prevents small unpaid claims from quietly turning into thousands of dollars in lost revenue by the end of the year. Consistency here matters more than complexity.
Want this already built out for you?
Everything above is the same follow-up structure I use with clients — but writing it down is one thing, and actually having it ready to go every week is another. My Mental Health Billing SOP Toolkit includes this follow-up routine (and the rest of the billing workflow above) as ready-to-use templates, so you’re not rebuilding it from scratch every Monday.
Should You Outsource Billing?
A lot of solo therapists handle billing themselves at first, and many do it successfully. But as caseloads grow, billing is usually one of the first things they look to hand off — and for good reason.
A good mental health biller handles claim submission, payment posting, insurance follow-up, appeals, accounts receivable management, and monthly reporting. That’s a significant amount of administrative time back in your week.
Outsourcing doesn’t make sense for everyone, but if billing is consistently taking time away from clients or sitting on your to-do list longer than it should, it’s worth considering.
If you’re leaning toward learning this yourself rather than outsourcing it, Bill Like a Boss walks through this exact workflow in more depth.
Final Thoughts
A smooth billing workflow doesn’t just happen. It’s built step by step, and it only works if you follow it consistently.
The practices I’ve seen do well with billing aren’t always the ones with the biggest teams or the fanciest software. They’re the ones with clear systems that everyone actually follows.
Understanding the full process — even if you eventually hand it off — helps you ask better questions, catch problems earlier, and make decisions that protect your revenue.
Billing may never be anyone’s favorite part of running a practice. But it doesn’t have to be the most stressful part either.
Frequently Asked Questions
How long does the mental health billing process take?
Most electronic claims are processed within two to four weeks, though timelines vary depending on the insurance company and the complexity of the claim.
What’s the most important step in the billing workflow?
Insurance verification, without question. Confirming benefits before the first appointment prevents most of the common billing problems I see — and it’s one of the most consistently skipped steps.
Can therapists manage their own billing?
Yes, and many do successfully. It works best when you have reliable systems and an EHR with solid built-in billing tools. The challenge tends to come when caseload grows and billing starts competing with everything else.
What happens if a claim is denied?
Don’t ignore it. Review the denial reason carefully — many denials can be corrected, appealed, or resubmitted if you catch them quickly. Letting them sit is where practices lose money.
