Medical Billing: What Are the Most Common Causes of Claim Denials?

[chrishill_us]

I’m looking into the most common challenges healthcare practices face with medical billing service, especially when claims are denied or delayed.

From your experience, what usually causes the biggest billing issues? Is it more often incorrect patient information, coding errors, missing documentation, eligibility problems, or insurance-specific requirements?

I’m also interested in hearing what processes you use to catch these issues before claims are submitted. Do you rely mainly on billing software, manual claim reviews, or a combination of both?

It would be helpful to hear what has worked well for different practices and how you handle recurring denials without creating extra administrative work.

Thanks!
