Why Claim Denials Keep Happening—and What You Can Do
Let me share something I’ve learned over 15 years in medical billing and coding at MBC—most claim denials are preventable with the right strategy.
I’m Maria L., CPC—and I’ve spent over a decade helping OB-GYN, family medicine, and dermatology practices figure out why their claims keep getting denied.
And here’s the truth: It’s not random. It’s rarely just a “mistake.”
Most of the time, it’s a pattern.
At Medical Billers and Coders, I’ve worked with countless practices that thought their billing was under control—until they saw how much revenue they were losing each month from avoidable claim denials.
Here’s what’s really going wrong—and how to stop it.
1. Documentation Doesn’t Support the Code
This is one of the most common causes of claim denials.
A provider performs a complex service—but the documentation doesn’t reflect it clearly enough.
If you’re billing a level 4 visit (99214), the note must show the visit’s complexity.
Otherwise, payers will downcode—or deny—it.
I worked with an OB-GYN practice in Georgia that had more than 60% of their level 4 visits downcoded. The issue? Their EMR templates were too vague.
At MBC, we rewrote their templates to meet payer documentation standards—and their denial rate dropped fast.
2. Modifiers Are Being Applied Incorrectly
I’ve seen this time and again—modifiers used like duct tape.
Coders are often told to “just add Modifier 25 or 59” to get a claim through. But payers are smarter than that now.
They’re watching especially closely in specialties like dermatology and gynecology, where E/M visits and procedures happen on the same day.
At MBC, we never rely on shortcuts. Every claim goes through line-by-line review. No auto-fill modifiers. No assumptions. That’s the level of accuracy needed to avoid rejections.
3. Your Team May Be Using Outdated Payer Rules
Payer guidelines change constantly. If your staff isn’t tracking those changes weekly, you’re likely billing with old rules—and setting yourself up for denials.
I once audited an internal medicine group whose team kept billing a code that had been bundled for months. Their system didn’t catch it—and neither did their coders.
This is why MBC updates clients weekly with payer-specific rule changes.
Because staying current is non-negotiable.
4. Denied Claims Aren’t Being Worked
Here’s the reality: A denied claim isn’t dead—until you give up on it.
But many practices don’t have the time or bandwidth to appeal.
During onboarding, I often find 60+ day-old denials just sitting in systems.
At MBC, we assign AR specialists dedicated to working denials daily.
We recover what’s already earned—before it turns into lost revenue.
5. Your Billing Team Is Overwhelmed
I’ve worked with great billers who just didn’t have the capacity to keep up.
Answering phones, managing pre-auths, checking eligibility—and then coding at night? That’s a recipe for burnout.
And when burnout hits, errors increase. And errors mean more denials.
At MBC, we don’t just support your team—we become your billing team.
We give providers the space to focus on care, while we handle the coding and collections that keep the practice running.
What I’ve Learned After 15 Years in the Trenches
If you’re seeing rising denial rates, don’t just ask “What’s going wrong?”
Ask: “Who’s watching our back?”
I’ve spent over 15 years helping practices catch what others missed.
And I can tell you firsthand—most denials are fixable with the right team and the right tools.
At MBC, we’ve helped hundreds of practices lower their denial rates—many in under 30 days.

FAQs: What You Need to Know About Claim Denials
Most claim denials are caused by coding errors, missing documentation, late filing, or lack of pre-authorization.
A rejected claim wasn’t processed due to errors. A denied claim was processed but not paid due to medical or policy issues.
Start by reviewing the denial code. Then gather your documentation and file an appeal if it’s justified. Most denied claims can be recovered.
Denial management is the process of identifying, correcting, and resubmitting denied claims. It helps practices protect revenue and improve cash flow.
Submit claims on time, use correct codes and modifiers, document thoroughly, verify insurance, and track payer policy updates.
Deadlines vary, but most payers give you around 90 days from the date of service. Don’t wait—denials age quickly.
