Choosing a mental health billing company feels a lot like hiring a contractor. Everyone sounds great on the phone, their website looks polished, and they all promise fast turnaround and high reimbursement rates. But once you’re locked into a contract and the claims start piling up, the real picture emerges. And by then, you’re already six months deep with a revenue cycle that’s underperforming and a billing partner who’s hard to reach.
We’ve seen it play out more times than we’d like to admit. Mental health practices, substance use disorder treatment centers, and behavioral health organizations of all sizes come to us after a frustrating experience with a billing company that overpromised and underdelivered. The good news is that with the right questions upfront, you can avoid that headache entirely.
Here’s what to ask—and what the answers should sound like—before you sign anything.
Do You Specialize in Mental Health Billing?
This sounds obvious, but it’s the most important question on this list. Medical billing is not one-size-fits-all. Behavioral health billing—whether that’s outpatient therapy, intensive outpatient programs, partial hospitalization, medication-assisted treatment, or residential substance use services—operates under its own set of coding rules, payer quirks, authorization requirements, and compliance considerations.
A general medical billing company that “also handles behavioral health” is not the same as a company that lives and breathes behavioral health billing and coding every day. Ask specifically: what percentage of your client base is behavioral health? What experience do you have with the specific service types and payer mixes relevant to my practice? The answers will tell you a lot very quickly.
How Do You Handle Claim Denials?
Denials are an unavoidable part of mental health billing, but what separates a good billing company from a great one is what happens next. Some companies will work denials aggressively, appealing every legitimate claim and tracking root causes to fix systemic issues. Others will write off denials as a cost of doing business and move on.
Ask for their average denial rate and their denial overturn rate. Ask who is responsible for working denied claims and what their timeline looks like. If they’re vague or defensive about these numbers, that’s a red flag worth taking seriously.
What a Forensic Billing Assessment Actually Uncovers
You can’t fix what you can’t see. A forensic review exposes the revenue leaks most practices don’t know they have.
Hidden Denial Patterns
Identify recurring payer trends, coding issues, and documentation gaps that quietly increase your denial rate.
Underpayments
Detect claims paid below contracted rates and uncover missed reimbursement opportunities.
Aging Accounts Receivable
Break down AR over 60, 90, and 120 days to determine what’s recoverable—and what’s at risk.
Authorization Lapses
Reveal missed or expired authorizations that directly impact billable treatment days.
Credentialing Gaps
Identify enrollment delays or re-credentialing issues that prevent claims from being paid.
Reimbursement Performance
Analyze payer-specific reimbursement rates and benchmark financial performance.
What Does Transparency Look Like in Your Reporting?
You should never have to wonder what’s happening with your revenue cycle. A quality behavioral health billing partner will provide clear, regular reporting on key metrics such as claims submitted, claims paid, aging accounts receivable, denial trends, and reimbursement rates by payer. You should have visibility into your financial performance at any time, not just when you ask for it.
Ask to see a sample report. Ask how often they provide updates and through what method. If the answer involves a lot of “we’ll send you whatever you need” without a defined process, that’s not the transparency you’re looking for.
Are You Familiar With Our Specific Payers?
Payer contracts and requirements vary significantly, and behavioral health adds another layer of complexity. Medicaid billing varies state by state. Commercial payers each have their own authorization quirks and fee schedules. Medicare has specific documentation requirements for behavioral health services that differ from other specialties.
A billing company that knows your specific payers—their timely filing limits, their authorization processes, their common denial reasons—is going to perform significantly better than one that’s learning on the job with your revenue. Ask directly about their experience with the payers that make up the bulk of your practice’s volume.
Do You Support Utilization Review?
This one is often overlooked during the vetting process, but it matters for mental health providers, especially those running higher levels of care like IOP, PHP, or residential programs. Utilization review is the process of working with payers to justify the medical necessity of ongoing treatment, and it has a direct impact on your authorization approvals, your denial rates, and your revenue.
A billing partner that understands utilization review is a fundamentally different resource than one that only processes claims. Ask whether utilization review support is part of their service offering and how they coordinate with your clinical team when authorizations are at risk.
Do You Handle Credentialing?
Credentialing is one of those things that seems administrative until it isn’t, and then it becomes a very expensive problem. Gaps in provider credentialing mean claims get denied, reimbursements get delayed, and revenue stalls while your team scrambles to sort out paperwork.
Ask whether your prospective billing partner offers credentialing services, how they track re-credentialing timelines, and how they handle credentialing for new providers joining your practice. A billing company that manages both credentialing and billing and coding under one roof creates fewer handoff errors, faster payer enrollment, and a more seamless revenue cycle overall.
What Does Onboarding and Ongoing Communication Look Like?
The transition to a new billing company is always a vulnerable period for a practice’s cash flow. A good partner will have a defined, organized onboarding process that minimizes disruption and gets claims moving quickly. Ask how long onboarding typically takes, who your dedicated point of contact will be, and how they handle communication day-to-day.
If you’ll be bounced between different staff members with no consistent contact, or if communication is primarily through a ticketing system rather than a real person who knows your account, that’s worth knowing before you sign.
