How to Reduce Claim Denials for Mental Health Practices

As a mental health practice, you can provide excellent care and still not get paid.

Most of the time, the problem isn’t the care itself, but what happens after the patient leaves. A missed authorization, incorrect billing code, or incomplete claim: All of these can turn a completed appointment into an unpaid claim. 

This is far more common in the USA than you think. According to a KFF analysis of federal data, insurance plans through HealthCare.gov denied 20% of all claims in 2024. 

Additionally, a 2024 analysis of professional mental health claim denials by the Massachusetts Health Policy Commission found that 10% of professional mental health claims were denied. Administrative reasons accounted for 67% of those denials, including incomplete claims, coding errors, coverage issues, and duplicate claims. 

So, why do mental health claims get denied, and what can practices do to prevent them? Let’s take a closer look. 

Why Are Mental Health Claims Denied? 

Some of the most common reasons mental health claims get denied are also some of the most avoidable, including manual errors and untimely filing. 

• Eligibility and coverage issues: The patient’s insurance is inactive or doesn’t cover the service provided.
• Prior authorization problems: Required authorization is missing, incorrect, expired, or exceeds approved limits.
• Coding and billing errors: Incorrect CPT or ICD-10 codes, modifiers, or claim details. 
• Documentation issues: The submitted documentation doesn’t adequately support the service or its medical necessity.
• Timely filing: The claim is submitted after the payer’s deadline.
• Provider or network issues: Credentialing, enrollment, or network status problems affect reimbursement.

7 Ways to Reduce Claim Denials in Mental Health Practices

To avoid claim denials, identify where these issues enter the revenue cycle and fix them before they affect reimbursement. A proactive approach can reduce avoidable denials and save time on claim corrections. 

1. Verify Patient Eligibility and Benefits

First things first, check for the patient’s eligibility. This doesn’t just mean checking whether the policy is active; it also means checking behavioral health benefits, coverage limits, deductibles, copays, and network status. This can help you spot coverage changes and inactive policies before you start treatment. 

2. Stay on Top of Prior Authorization Requirements

With mental health, authorization can be tricky to figure out. Most services require authorization, and you’ll need to verify approved services, visit limits, the authorization period, and any other payer requirements. Don’t forget to monitor expiration dates and remaining authorized sessions, particularly when patients receive ongoing therapy. 

3. Improve Mental Health Coding and Documentation Accuracy

Speaking of administrative errors, inaccurate medical coding is a common mishap in insurance claims. Use the appropriate CPT and ICD-10 codes, modifiers, and provider information for each service. Clinical documentation should also support the billed service and its medical necessity, if required. 

4. Submit Clean Claims the First Time

With Electronic Health Records (EHR), you can offer clients self-service options to confirm the accuracy of their personal details and health history. This step can drastically reduce your burden of reviewing claims for errors before they reach the payer. You can quickly review patient and provider information, diagnosis and procedure codes, and other payer-specific requirements. 

5. Track Claims and Follow Up on Rejections Quickly

Your job doesn’t end with claim submission. You need to monitor the claim status and investigate unpaid claims promptly before they impact your revenue management. Identify the cause if the claim is rejected, correct the necessary information, and resubmit it within the required timeframe. 

6. Analyze Denial Trends, Not Just Individual Claims

If you’re witnessing a pattern of claim denial, then there’s a deeper issue within your process. Track the reasons by payer, service, and dollar value. For example, if you see repeated authorization denials, then you need a better system for monitoring authorization assessment and expiration dates. 

7. Consider Outsourcing Revenue Cycle and Denial Management

We get it. As a mental health practice, your expertise is not reviewing insurance claims or managing your revenue cycle. Sure, it is manageable on a smaller scale. But as your practice grows, you need to manage eligibility, coding, claims, follow-ups, all with the limited team you have. 

As demand grows, persistent denials, rising accounts receivable, or limited billing expertise may signal a need for additional RCM support. A specialized medical RCM partner can manage these processes, identify recurring issues, and help practices maintain a more consistent revenue cycle.

What to Do When a Mental Health Claim Is Denied

Even with a strong prevention process, some claims will still be denied. When that happens, a clear response process can help you recover appropriate reimbursement and prevent the same issue from recurring.

However, many denied claims never reach the appeal stage. Research shows that fewer than 1% of denied in-network claims were appealed in 2024, and insurers upheld 66% of appealed decisions. This suggests most denials are minor and can be fixed with resubmission. 

Identify the Reason for the Denial

Begin by checking the payer’s denial code, explanation of benefits, or remittance advice. Connect whether the issue relates to eligibility, authorization, coding, documentation, coverage, or timely filing. 

Determine Whether to Correct or Appeal

Many claims are rejected for simple errors. Hence, there’s no point in appealing. If the claim contains an error, such as incorrect coding or missing information, submit a corrected claim according to the payer’s requirements. If the claim was denied despite the service meeting coverage requirements, an appeal may be appropriate. Include the relevant documentation and supporting information the payer requires.

Fix the Underlying Issues

You can’t keep fixing the same problems. Review recurring denial reasons to determine where the issue originated. For example, repeated denials due to inaccurate coding indicate a need for additional coding review and staff training. 

Track Denials, Appeals, and Follow-Ups

To keep a better track of your revenue, keep a record of the denied claims, reasons, corrective actions, appeal deadlines, and submitted documentation. This keeps you in the loop on resubmission status and helps you track follow-ups.

FAQs About Mental Health Claim Denials

What Are the Most Common Reasons Mental Health Claims Are Denied?

Some of the most common reasons why mental health claims are denied are because of eligibility or coverage issues, missing prior authorization, coding or billing errors, insufficient documentation, timely filing issues, or non-covered services.

How Can Mental Health Practices Prevent Claim Denials?

A mental health practice can reduce claim denials by verifying insurance eligibility, confirming authorization requirements, maintaining accurate coding and documentation, reviewing claims before submission, and tracking recurring denial patterns.

How Does Prior Authorization Affect Mental Health Claim Denials?

When a payer requires prior authorization for a certain number of visits or a specific scope of care, missing or incorrect authorization can result in a denied claim. Practices should verify requirements in advance and track authorization periods and approved services. 

What Should a Mental Health Practice Do When an Insurance Claim Is Denied?

First, review the denial reason and determine whether the claim needs correction or an appeal. If an appeal is appropriate, submit the required documentation within the payer’s deadline and track the outcome. 

When Should a Mental Health Practice Outsource Medical Billing?

Outsourcing medical billing may make sense when claim denials and accounts receivable are increasing, billing takes up too much staff time, or the practice lacks specialized RCM expertise. An RCM partner can manage billing and denial processes so the practice can focus on patient care.
