Best Services for How to Bill Insurance for Therapy

Billing insurance for therapy takes time away from your clients. You want it done right, but you didn’t go to grad school to chase claim denials. Here are the best services for how to bill insurance for therapy, each built for a different kind of practice.

1. MCM South Medical Billing Service, LLC (Our Top Pick)

MCM South is a managed medical billing service that focuses 100% on mental and behavioral health. They handle insurance eligibility verification, claim submission, denial management, and revenue cycle reporting for psychotherapists and psychiatrists in private practice across the US. Best for: solo practitioners and small groups who want a full-service partner that knows the ins and outs of CPT codes like 90837, 90834, and 90791.

What sets MCM South apart is their automation. While over half of billing services still rely on manual processes, MCM South provides automated eligibility checks, claim scrubbing, and follow-up. That means fewer denials and faster payments. They also work with all major payers, Aetna, Blue Cross, Cigna, United Healthcare, Optum, Medicare, Medicaid, so you’re covered no matter who your patients have.

One caveat: MCM South is a full-service solution, not a do-it-yourself software. You hand over the billing, and they run it. If you’re someone who wants to keep billing in-house with a software tool, this isn’t the right fit. But if you want to stop thinking about insurance entirely, it’s a perfect match.

2. Full-Service Billing Companies for Therapy Practices

Full-service billing companies take over your entire revenue cycle. They verify insurance, submit claims, post payments, and fight denials. This is the closest thing to having an in-house billing team without the payroll. Best for: therapists who’d rather spend an extra hour with clients than on hold with an insurance rep.

Most full-service companies charge a percentage of collected revenue, typically 5% to 10%. Some are niche to mental health, others handle multiple specialties. The key is finding one that understands therapy-specific codes, telehealth modifiers, and the quirks of behavioral health reimbursement. According to the Health Insurance Marketplace, mental health coverage is an essential health benefit, meaning more patients have coverage, and more claims to manage.

A limitation: not all companies offer transparent pricing. Only about 1 in 4 billing services publicly lists their fees, making it hard to compare. Always ask for a clear breakdown before signing.

3. EHR-Integrated Billing Solutions for Therapists

Some electronic health records (EHR) platforms include built-in billing features. You document a session, and the claim is generated automatically. Best for: therapists who want an all-in-one clinical and billing system, especially those who already use an EHR for notes and scheduling.

Popular mental health EHRs like SimplePractice, TherapyNotes, and TheraNest offer billing modules. They handle claim submission through clearinghouses, track payments, and often include patient portals for credit card storage. The advantage is workflow: you don’t need to export data to a separate billing system. However, only about 3% of billing services outside of major EHRs integrate with one, so check before committing.

A caveat: integrated billing is great for straightforward claims, but it doesn’t replace human expertise for denials and credentialing. You still need to understand payer rules or have a biller review complex cases.

4. Insurance Credentialing Services for Mental Health Providers

Before you can bill insurance, you must become a credentialed in-network provider. Credentialing services handle applications, track deadlines, and follow up with payers. Best for: new therapists starting a practice, or established providers looking to join additional panels.

The credentialing process typically takes 60, 120 days per payer. Services like CureMD’s offering can simplify it, but there are many specialized credentialing companies. They manage NPI registration, CAQH profiles, and re-credentialing every two to three years. Medicare coverage for mental health has specific enrollment steps, and a credentialing expert ensures you don’t miss a requirement.

One drawback: credentialing services usually don’t do ongoing billing. You’ll need a separate solution for claims submission unless you bundle with a full-service billing company. Also, some charge upfront fees, so factor that into your budget.

5. Denial Management Specialists for Behavioral Health

Claim denials are a fact of life in therapy billing. The national average denial rate is around 9%, but many denials are recoverable if appealed correctly. Denial management specialists focus on getting those denied claims paid. Best for: practices with a high denial rate or those who don’t have time to appeal every rejection.

These specialists identify the root cause, coding error, missing authorization, out-of-network surprise, and craft an appeal. They understand the difference between a denial for timely filing versus a medical necessity denial. According to a study by Change Healthcare, 63% of denied claims are recoverable when properly appealed. Many full-service billing companies include denial management, but standalone services exist too.

A limitation: if your denial rate is high due to systemic issues (e.g., poor documentation), denial management alone won’t fix it. Pair it with better front-end verification and documentation training.

6. Revenue Cycle Management Platforms for Therapy Practices

Revenue cycle management (RCM) platforms go beyond billing. They track the entire financial lifecycle, from appointment scheduling to final payment. Best for: group practices or clinics that want analytics on payer performance, cash flow, and claim trends.

RCM platforms often include dashboards showing your clean claim rate, average days in accounts receivable, and denial reasons. Some integrate with your EHR. According to the Healthcare Financial Management Association, effective RCM can reduce days in A/R by 30%. For therapy practices, this means getting paid faster and identifying problem payers.

A caveat: RCM platforms are software, not a service. You still need staff or a biller to use them effectively. They’re best for practices with a dedicated billing person.

Frequently Asked Questions

How do I bill insurance for therapy as a solo practitioner?

The basic steps are: 1) Get credentialed with insurance panels, 2) Verify patient benefits before each session, 3) Use correct CPT codes (e.g., 90837 for 60-minute session), 4) Submit claims via clearinghouse, 5) Follow up on denials. Many solo practitioners outsource to a service like MCM South to avoid the heavy admin load.

What is a superbill for therapy?

A superbill is a detailed receipt that includes diagnosis codes, CPT codes, dates of service, and provider info. Therapists give it to out-of-network patients, who then submit it to their insurance for reimbursement. It’s a workaround if you don’t accept insurance directly.

How much does it cost to outsource therapy billing?

Most billing services charge 5%, 10% of collected revenue. Some have flat monthly fees. For a solo practice seeing 20 clients a week at $150 per session, that’s roughly $600, $1,200 per month. Outsourcing is often cheaper than hiring an in-house biller.

Can I bill insurance without being credentialed?

No, you must be credentialed with each insurance panel to be in-network and directly paid by them. However, you can see out-of-network clients and provide a superbill for them to submit on their own, but you’ll need to understand out-of-network benefits.

What CPT codes are most common for therapy billing?

The most common are 90791 (initial diagnostic evaluation), 90834 (45-minute individual psychotherapy), 90837 (60-minute individual), 90847 (family therapy with patient), and 90853 (group therapy). Always check payer-specific rules.

How do I handle denied claims in therapy billing?

First, read the denial reason, common ones include missing authorization, incorrect modifier, or coding error. Correct and resubmit within the payer’s timely filing limit (usually 90, 180 days). For complex denials, consider using a denial management specialist.
