5 Dental Billing and Coding Denial Reasons and How to Reduce Them by 80%
Find out why Dental Billing and Coding claims get denied and how dental practices prevent errors, reduce denials, and improve revenue cycle performance.
The dental revenue cycle is a problem that is increasingly challenging for practices in the United States. Denied claims, growing administrative burdens, and inaccurate dental billing and coding are costing money. An estimated loss of $15 billion to the U.S. dental industry occurs each year from claim denials, claim documentation failures, and inefficient claims billing.
It impacts dental practices of every scale, from individual providers to huge Dental Service Organizations. Proper dental billing and coding practices can help practices avoid claims errors, late payments, and more administrative strain. The denial issue keeps getting worse, as 78 percent of dental offices say denials have increased or payers are being more vigilant about them in the last year.
Why Nearly One in Five Dental Claims Gets Denied
Recent statistics reveal that about 15% of dental claims end up being denied by insurance providers, and 19.3% are denied upon initial submission. Almost one in five claims is delayed right from the start. This rejection rate has been rising in recent years. Increased claim rejection rates from dental practices are caused by coding, under documentation, eligibility, and evolving payer requirements. To avoid these lost revenues, it is necessary to employ effective dental billing and coding practices.
How Denials Create a Domino Effect on Your Revenue Cycle
Each denied and delayed claim adds to the dental revenue cycle. Staff spend time correcting claims, chasing up payers and dealing with resubmissions instead of patient care and growth activities. Also, insurance processing delays and incorrect balances can lead to billing issues for patients. In the meantime, practices are subject to random cash flow and rising admin costs.
An average of 9% of collectible revenue is lost in practices using inefficient revenue cycle processes because of a variety of denied claims, delayed follow-up work and missing communication. Having a good dental billing and coding workflow can help you identify mistakes sooner, ensure claims are accurate, and helps to receive reimbursements faster.
Financial losses from dental claims aren’t just from unpaid claims. Every claim that is rejected must be reviewed, corrected, and then go through the administration process again before claims can be recovered. These expenses can be hundreds of thousands of dollars per year for medium-sized practices.
The $280K Revenue Loss From Dental Denials
Around $280,800 can be lost from a medium-sized dental practice each year because of claim denials. The losses can come from billing problems, missing documentation and the needs of the payers that affect dental billing and coding accuracy.
Financial effects increase if practices take into account the cost of denial follow-up. Rejected claims require several hours a week of review, error correction and communication by staff members with payers. The more steps involved, the higher the administrative cost and the longer the reimbursement takes. Whenever possible, eliminate preventable denials so dental practices can capture the income that has already been earned due to patient services rendered.
The Hidden Operational Costs of Denied Claims
Dental claim denials come at a price. For each deny, dental billing and coding services will have to follow-up with claim investigation, documentation review, claim corrections and resubmissions.
| Hidden Cost | Impact on Dental Practices |
|---|---|
| Staff time | Reduces focus on patient support and revenue activities |
| Claim rework | Increases administrative expenses |
| Delayed payments | Slows cash flow and collections |
| Staff burnout | Creates workflow pressure and turnover risks |
| Patient confusion | Increases billing complaints |
Patient experience is also impacted by high denial volumes. When wrong dental billing and coding or delayed insurance processing, or even an unexpected balance occurs, it decreases patient satisfaction and trust.
Why Most Denied Claims Never Recover Revenue
Following up on denied claims is one of the greatest monetary issues dental practices face. Limited staff resources, complicated payers’ requirements, or workflow inefficiencies are among the factors that prevent many practices from resubmitting and appealing rejected claims. If there is an absence of good dental billing and coding, denied claims may not be resolved. Without documentation, paperwork errors, or missed follow-ups, practices can lose out on monetizing earned revenue.
Industry statistics reveal that many denied claims are never reworked, resulting in huge revenue loss opportunities. Structured denial management can help uncover why claims are denied, prioritize high dollar claims and increase recovery. When properly dental billing and coding to patients, along with being able to monitor denials proactively, practices can recover more payments, reduce revenue leakage, and have a healthier revenue cycle.
The 5 Dental Claim Denial Reasons and Solutions
Dental billing and coding are a crucial part of the dental practice and depend on the accuracy of patient details, proper procedure coding, and documentation. Simple billing mistakes can result in late payments and in loss of revenue. By comprehending common denial reasons, practices can enhance claim accuracy and have better revenue cycle management.
Denial Reason 1: Missing Insurance Verification
One of the most frequently occurring problems in dental billing and coding is that it will not be verified as complete. Claims are frequently denied before being processed due to expired policies, inaccurate coverage information, or lack of authorizations.
Solution:
Confirm insurance coverage prior to scheduled visits. Verify coverage, benefit limits, deductibles, and authorization. This proper verification can eliminate unnecessary claim rejection.
Denial Reason 2: Incorrect Patient Information
If there are incorrect patient details this can delay the claim. It’s common for names, policy numbers, addresses or member information to be incorrect, which leads to rejection by the payer.
Solution:
Check the patient’s details at each appointment. Keep insurance records up to date and verify information before treatment to increase the accuracy of claims.
Denial Reason 3: Incorrect CDT Code Selection
One of the biggest issues that arise in dental billing and coding is the selection of the appropriate CDT code. If the procedure is performed with a code that is not the one used, the claim may be rejected or reimbursement may be delayed. For instance, an intraoral complete series (D0210) could be confused with a panoramic radiographic image (D0330) and thus cause coding errors.
Solution:
Be sure to read the CDT codes carefully for the procedure that is documented. Frequent coding education assists to preserve accuracy.
Denial Reason 4: Outdated CDT Codes
New, revised and deleted codes are incorporated into the ADA every year. Older codes cause compliance problems and raise the likelihood of denials from payers.
Solution:
Make sure billing software, coding reference and employee training materials are updated for each CDT revision. The knowledge of the current coding aids in claim accuracy.
Denial Reason 5: Insufficient Documentation
Payers’ claim supporting documentation is weakened by incomplete documentation. It can be difficult to get procedures approved when X-rays, periodontal charts, or clinical notes are missing.
Solution:
Ensure that all claims have full clinical documentation. Supporting documentation should be clear and could provide adequate rationale for the billed procedure and follow coding guidelines.
