Claim denials are one of the biggest threats to a healthcare practice’s revenue. The American Medical Association estimates that denied claims cost the U.S. healthcare system over $262 billion annually — and most of those denials are preventable. Whether you run a solo practice or a multi-specialty group, understanding why claims get denied and how to stop it is essential to keeping your revenue cycle healthy.
What Is a Claim Denial?
A claim denial happens when an insurance payer refuses to reimburse a healthcare provider for services rendered. Denials can be either hard (permanent, requiring an appeal or write-off) or soft (temporary, fixable with corrected information). According to industry data, up to 90% of denied claims are recoverable — but only if caught and addressed quickly.
Top Reasons Medical Claims Get Denied
Before you can reduce denials, you need to know what’s causing them. Here are the most common reasons:
- Incorrect or missing patient information — Wrong date of birth, insurance ID, or policy number on the claim.
- Eligibility issues — The patient’s coverage had lapsed, or the service wasn’t covered under their plan.
- Coding errors — Using the wrong ICD-10, CPT, or HCPCS code, or mismatching a diagnosis code with a procedure code.
- Missing prior authorization — Certain procedures require pre-approval from the payer before services are rendered.
- Timely filing violations — Submitting claims after the payer’s deadline (often 90–180 days from the date of service).
- Duplicate claims — Submitting the same claim twice, often due to a system error.
- Bundling and unbundling errors — Incorrectly separating procedure codes that should be billed together, or vice versa.
7 Proven Strategies to Reduce Claim Denials
1. Verify Insurance Eligibility Before Every Appointment
One of the single most effective things you can do is verify patient eligibility before they walk through the door. Confirm that the patient’s insurance is active, that the provider is in-network, and that the planned service is covered. This takes minutes and prevents a significant percentage of denials before they happen.
2. Use a Claims Scrubber Before Submission
A claims scrubber is software that automatically reviews each claim for errors before it’s submitted to the payer. It checks for missing fields, invalid codes, mismatched diagnosis-procedure pairs, and payer-specific rules. At TBC Solutions, our claims scrubbing technology achieves a first-pass acceptance rate of up to 98%, meaning most claims are paid the first time they’re submitted.
3. Invest in Accurate Medical Coding
Coding errors are among the leading causes of denials. Your coding team must stay current with ICD-10, CPT, and HCPCS updates, which change annually. AHIMA and AAPC certified coders bring the expertise needed to assign precise codes that payers accept. If your in-house team is stretched thin, outsourcing your coding to certified specialists is often the most cost-effective solution.
4. Track and Analyze Your Denial Patterns
You can’t fix what you don’t measure. Build a denial tracking system that captures the reason code, payer, service type, and dollar amount for every denied claim. Over time, patterns will emerge — perhaps a specific payer is consistently denying a particular procedure code, or one provider’s documentation is incomplete. Data-driven denial management turns a reactive process into a proactive one.
5. Appeal Every Recoverable Denial
Many practices write off denied claims rather than appeal them, leaving significant revenue on the table. Set a policy to appeal all denials where the service was legitimately rendered and covered. Most payers have a 30–60 day window for appeals. A dedicated AR team that follows up on denials within 24–48 hours can recover a substantial portion of denied revenue.
6. Stay on Top of Payer Policy Changes
Insurance payers update their coverage policies, billing rules, and prior authorization requirements regularly. A claim that was accepted last year may be denied today if you’re not aware of policy changes. Subscribe to payer newsletters, attend regular staff training, and maintain a payer-specific reference library for your billing team.
7. Consider Outsourcing Your Medical Billing
For many practices — especially small and mid-sized ones — the most effective way to reduce denials is to partner with a professional medical billing company. A dedicated billing team handles eligibility verification, claim scrubbing, coding review, timely submission, denial management, and appeals. The result is a cleaner revenue cycle with fewer denials and faster reimbursements.
