Mental health billing services for therapy group practices

What a mental health billing service does

A mental health billing service turns each completed session into a paid claim. It works the same way for therapists, counselors and psychologists.

For every session, the biller first checks that it has a code, a diagnosis and the right clinician attached. The claim goes to the payer, and the payer pays it, pends it or denies it. Each payment is posted against its session so the balance is right. Pending claims get a follow-up call or a portal check. Denied claims get corrected and resubmitted, or appealed when the payer made the mistake. The client’s share, such as a copay, deductible or coinsurance, goes on a statement. Out-of-network clients may need a superbill, or a claim filed for them. Card chargebacks and billing disputes need a reply. Each month, someone should tell you what was billed, what was paid and what is still owed. That report should break the money down by payer and by age.

Why many denials start before the claim is sent

Many claim denials trace back to data collected before the claim is sent. Experian Health’s 2025 State of Claims survey asked 250 healthcare professionals who make billing and claims decisions about denials. The top reasons were missing or inaccurate data (50%), authorizations (35%) and incomplete or inaccurate patient registration data (32%).

In a therapy practice, those errors often start at intake. A member ID is typed with one digit wrong. The client changed plans in January and nobody checked again. The name on the claim doesn’t match the insurance card. The clinician isn’t in network for that plan yet. Or the client has a deductible nobody mentioned, and the first statement comes as a surprise. When intake and billing sit with different people, the biller often learns about the error only when the denial comes back. By then the session has happened, and the fix means calling the client, correcting the record and sending the claim again. A team that runs intake and billing together can check these details before the first session. It can also send each fix back to intake, so the next new client’s record starts out right.

At Cortexa, the team that answers new inquiries verifies insurance eligibility and in-network status at intake. For out-of-network and self-pay clients, we calculate deductible status, coinsurance and estimated out-of-pocket cost. We prepare a good faith estimate where the No Surprises Act requires one. CMS explains that people who aren’t using insurance usually get one when they ask or book at least 3 business days ahead.

Insurance, license and supervision are among the matching criteria your practice sets, so the clinician options a new client sees can reflect their plan. The client chooses the clinician. We fix and rebill claims rejected for correctable reasons.

Group practice billing for supervision, out-of-network claims and balances

Group practices bill in ways a solo practice often doesn’t. Pre-licensed clinicians may bill under a supervisor, some clients are out of network, and balances build up across many caseloads. Here is what our billing covers for a group.

Credentialing, so new clinicians can bill

A new clinician isn’t in network with a payer until the payer has credentialed them and the contract is in place. For a growing group, that step decides when a new hire’s sessions can be billed in network.

We manage insurance credentialing for your clinicians, including new applications, renewals and status tracking. It’s passed through at our actual documented cost. Your contracts stay in your practice’s name, and state licensing stays with the practice. The steps are on our page about credentialing for therapists.

When a billing-only company is the better fit

A billing-only company is the right choice for many practices. If you run a solo practice and your intake already works, a billing company or an independent biller may be all you need. The same goes for a group with a strong front desk and someone in house who does credentialing. In both cases the intake errors behind many denials are already under control, so paying a wider team to run intake as well would mostly add cost.

Compare the options side by side in the best mental health billing companies, and the cost of a billing company against an in-house biller in our guide to billing costs.

What you see and decide as the owner

You can check the status of any claim on your dashboard, any time. Practice Analytics comes with the membership and shows sessions, revenue, attendance, caseloads, capacity and clinician performance. You can also see where each new inquiry is in the pipeline.

Each month you get an accounts-receivable aging report, which shows what is still owed and how long it has been outstanding. Your account has a named billing lead. We review clinically substantive appeals with your practice before we send them. We set up payment plans as you direct.

How pricing works

Billing runs about 3% of what you collect, and the front desk, intake and billing together about 6%. We agree the exact scope and rate before you start. You can start with only the work you need most, for example billing and credentialing.

Practice Analytics is included with Full Service Partner at no extra cost. On its own it costs $50 a month.

For what billing companies charge and on what basis, see our guide to mental health billing costs.

There's no long-term contract, and there's a 30-day money-back guarantee.

What 6% costs at your size

At 6%, a practice collecting $100,000 a month pays $6,000. Subtract what you pay today for a biller, a billing company or an answering service to see the difference. See whether it pays for itself with your numbers.

Moving your billing to Cortexa

Cortexa is an operations team for independent therapy practices that runs the front desk, intake, billing, credentialing and payroll as one team. Billing is one part of the membership, and you can start with it on its own.

Before any switch, list the claims already in flight, the older unpaid balances and who owns each next step. That keeps old work from being dropped or billed twice. Which older balances we take on is part of the scope we agree before you start.

A company that does billing for a HIPAA-covered practice is a business associate. Federal rules list billing among the activities that create that relationship. We sign a BAA. PHI is stored on US servers, and our BAA commits that PHI is never used to train AI models.
