There’s nothing more frustrating than putting in the work, submitting an insurance claim, and seeing that dreaded word: Denied. It’s the last thing you want to deal with after a full day of sessions. But claim denials happen—and often, they can be avoided.
We’re going to walk you through the top five reasons mental health claims get denied and, more importantly, how you can prevent those denials from happening in the first place. Let’s save you some time (and headaches) down the road.
1. Incorrect or Missing Codes
This is probably the most common reason for claim denials. Every service you provide needs to be coded properly using CPT and ICD-10 codes, and if there’s even a small mistake—a typo, a missing digit, or the wrong code altogether—the claim is likely to get rejected. Think of these codes as the language that insurance companies speak, and if something’s lost in translation, they won’t know what you’re asking for.
How to prevent it:
Double-check your codes before submitting the claim. If you’re using billing software, most systems will alert you if something doesn’t look right. And if you’re unsure about which code to use, don’t hesitate to look it up or consult a professional.
2. Client Coverage Issues
This one can sneak up on you if you’re not careful. Sometimes, a client’s insurance doesn’t cover a specific service, or they may no longer be active on the plan they presented. Other times, they haven’t met their deductible yet, and the claim will bounce back to you as denied.
How to prevent it:
Always verify your client’s insurance benefits before the session. This step ensures that their coverage is active and that the service you’re providing is covered by their plan. It might feel like an extra task, but it saves you the hassle of dealing with denials later.
3. Timing Issues
Some insurance companies are sticklers for deadlines. If you wait too long to submit a claim, it may get denied purely because it wasn’t filed within the required time frame. Each insurance company has different rules about this—some give you 90 days, others a year, so it’s important to know the deadlines for each insurer.
How to prevent it:
Submit your claims as soon as possible after the session. This not only avoids timing issues but also helps you keep your billing workflow smooth. If you’re running behind on submissions, set up a system or reminder to make sure claims go out on time.
4. Incomplete or Incorrect Client Information
Even a small mistake in your client’s information—like a misspelled name, incorrect birthdate, or wrong insurance ID number—can result in a denial. Insurance companies need all the details to match up perfectly for the claim to go through.
How to prevent it:
Review the client’s information carefully before submitting a claim. It’s helpful to keep an up-to-date client file with all the correct details so you can refer back to it as needed. A quick cross-check can save you from having to correct and resubmit the claim.
5. Authorization Issues
Some services require pre-authorization from the insurance company before they’ll cover the session. If you skip this step, the claim is almost guaranteed to be denied, even if everything else is spot-on.
How to prevent it:
Before providing a service, especially for more intensive treatments or therapy plans, confirm whether or not the insurance company requires authorization. If they do, make sure you have that approval in hand before the session. Keep track of authorization numbers and dates so you can include them when submitting claims.
Bonus Tip: Stay Organized and Consistent
Consistency is key when it comes to reducing claim denials. Set up a system that allows you to stay on top of insurance verification, coding, and submission deadlines. Whether it’s through software, spreadsheets, or outsourcing your billing, having a reliable process in place will help you avoid many of these common issues.
Claim denials don’t have to be an inevitable part of running your practice. By taking a few preventive steps, you can minimize the chances of denial and keep your billing process running smoothly. And when denials do happen, just remember: they’re usually fixable with a little extra attention to detail.
