Top 8 Claim Denial Reasons in Behavioral Health and How to Fix Each One - Arule Health

A denied claim is more than just a payment delay.

For a growing behavioral health practice, claim denials can often translate into additional follow-ups, repeated documentation requests, and revenue that remains uncollected long after the session is over.

That said, most claim denials are preventable and stem from common reasons like expired authorization or unsupported psychotherapy codes. When such issues recur, your billing team might end up spending more time fixing claims and less time keeping payments on track.

Here are eight common reasons that might contribute to claim denials in your behavioral health practice and the fixes you can apply to resolve the issues:

1. Eligibility and Insurance Coverage Errors

A patient having an insurance plan does not necessarily mean every service or provider would be covered. Moreover, a patient’s coverage may have expired, their insurance details may be outdated, or their behavioral health benefits may not align with the expectations of the practice.

Fix:

  • Verify eligibility before treatment begins and recheck periodically
  • Record verification details so that billing staff can refer to the information in case of claim denials

2. Missing or Expired Prior Authorizations

Certain insurance plans require prior authorization in case of specific behavioral health services. A missing, incorrect, or expired authorization can also result in a denied claim. Claims may also get denied if practices unintentionally exceed approved visit or unit limits.

Fix:

  • Assign responsibility for monitoring remaining visits and renewal deadlines
  • Confirm whether the applicable service falls within the authorization’s scope before claim submission

3. Incorrect CPT Codes or Unsupported Service Levels

When a CPT code doesn’t match the service provided by your medical practice or the documentation does not support the billed level, your claim may be denied. This issue can specifically affect time-based psychotherapy codes such as 90832, 90834, and 90837.

Group psychotherapy faces a related but distinct version of this problem, since one CPT code (90853) has to support documentation for every patient in the session individually, not just the group as a whole.

Fix:

  • Align the selected code to the documented service and applicable coding requirements
  • Check proactively for any payer-specific requirements or coding errors before submission

4. Insufficient Documentation or Medical Necessity

Payers may deny claims when the clinical record fails to support the billed services. Missing treatment details, incomplete notes, or unclear diagnosis linkage may not sufficiently establish the need for treatment and cause problems during claim review.

Fix:

  • Establish standard documentation protocol for each payer and service type
  • For ongoing care, ensure that the paperwork (treatment plans and progress notes) supports the delivered services

5. Incorrect Patient, Provider, or Claim Information

Even minor data entry errors can prevent payers from matching claims to the correct provider or patient. Such errors are among the easiest to prevent, yet one of the most common reasons for denial.

Fix:

  • Validate patient demographics and insurance information against payer records
  • Use claim-scrubbing edits to catch common data errors before submission.

6. Telehealth Billing Errors

When billing for telehealth services, ensure you have included the correct place of service, haven’t omitted a required modifier, and have met the coverage requirements of the payer. Incorrect information in claims can otherwise lead to denials.

Fix:

  • Maintain an updated record of the current telehealth billing instructions for each major payer
  • Cross-check any basic rules and parameters with CMS telehealth billing guidelines and payer-specific policies for behavioral health billing.

7. Filing Deadlines Missed

Every payer has a filing deadline associated with claims, which should be adhered to. Claims submitted after the deadline may be denied even if all other information is complete and accurately filled. Long work queues or clearinghouse rejections that go unnoticed usually lead to missed deadlines on claims.

Fix:

  • Maintain and record the claim filing deadlines for every payer and monitor the claims that have either not been submitted or remain unaccepted.
  • Keep an eye on the clearinghouse rejections and review them every day or on a defined schedule

8. Duplicate Claims and Incorrect Resubmissions

Going through the process of getting a claim approved can be arduous, but behavioral health practices must avoid filing the same claim multiple times. Doing so can trigger duplicate claim denials, which often result from resubmitting claims without checking their status or sending a corrected claim as a new one.

Fix:

  • Check the status of every claim before resubmission
  • When submitting a correction, follow the payer’s instructions for corrected claims and include the information required for reference

Turn Denial Follow-Up Into Denial Prevention

If you currently have your hands full with denied claims and resubmitting them, it is time to pivot towards a proactive approach. Focusing on denial prevention can make a lasting difference to the revenue cycle of a behavioral health practice. Consistent eligibility checks, authorization tracking, coding reviews, complete documentation, and reviewing denial trends can help you prevent most denials.

Frequently Asked Questions (FAQs)

What are the most common reasons for behavioral health insurance claim denials?

Some of the most common reasons for behavioral health insurance claim denials include incorrect CPT codes, insufficient documentation, missing authorizations, and eligibility errors. However, the most frequent errors can also depend on the payer and practice, so review your denial data for accuracy.

Can a denied mental health claim be corrected and resubmitted?

In many cases, yes. If your claim has been denied due to an error that can be corrected and the payer permits the resubmission or correction, you can review the relevant details and go ahead with submitting the corrected claim.

How should a billing team handle a medical necessity denial?

Your billing team must first review the denial notice and compare the payer’s stated reason with the clinical documentation and applicable coverage policy. If supporting documentation is missing, follow the payer’s correction or appeal process.

When should a behavioral health practice appeal a denied claim?

Consider an appeal when the practice has grounds to challenge the payer’s decision and can support its position with the relevant documentation, policy, or contract terms. You must check the appeal deadline and submission requirements promptly to avoid missing any important ones.
