6 common billing errors and medical denials (and how to avoid them)
Learn the most common billing errors and insurance claim denials in private practice and actionable strategies to prevent issues like unbundling, upcoding, and missing prior authorizations, and ensure your practice runs smoothly.
Running a private practice isn’t just about providing excellent care – it also means managing the intricate and complex world of medical billing. When billing mistakes happen, they can delay payments, create confusion, and even harm the financial health of your practice. The good news for private practice owners: understanding the common medical billing errors and how to avoid them can ensure your billing operations are smooth and efficient. In this blog, we’ll dive deep into the most common billing errors that lead to medical claim denials and provide actionable strategies to help you prevent them.
1. Incorrect or Missing Information
One of the most common reasons for billing denials is inaccurate or incomplete client information. Whether it's incorrect demographic data, missing insurance details, or inaccurate provider information, these often minor errors can lead to claim rejections or delays.
Without correct client details, insurance companies won’t be able to process claims efficiently. This can result in your claims being denied outright or put on hold until the correct information is provided. To avoid this mistake:
- Double-check data at regular intervals: Ensure client information is updated regularly, and ask clients to confirm details like insurance provider, ID numbers, and demographic information.
- Utilize insurance verification tools: Invest in software or a practice management system that allows for real-time eligibility checks. This will give you an instant view of your client’s insurance coverage and prevent potential errors.
- Automate where possible: Tools that automatically verify client details at the time of booking and during check-in can significantly reduce human error and time spent on verification.
Remember, the small details matter. By ensuring accuracy in client information, you’ll minimize the risk of claim denials and save valuable time that would be spent resolving errors.
2. Coding Errors (Unbundling, Upcoding, and Downcoding)
Coding errors are another primary culprit in claim denials. This includes mistakes like unbundling, upcoding, or downcoding, which either result in overpayment or underpayment.
Unbundling (when services are separated into individual components instead of billed together) and upcoding (when a claim is submitted for a service that is more complex or expensive than what was actually provided) can lead to overbilling and can raise red flags with insurers or regulatory agencies, potentially resulting in audits or legal consequences.
Downcoding (incorrectly submitting a claim for a less complex service), though less risky legally, can negatively affect the financial health of the practice as it may not reflect the true cost of the care provided.
These types of coding errors can lead to rejected claims or financial penalties from insurance companies. More importantly, they can put your practice under scrutiny if codes don't match the services provided, and in some extreme cases, may even be considered fraud.
In order to avoid these risks, we recommend you:
- Use coding software: Invest in medical coding software that helps identify unbundling or other common coding errors, ensuring accuracy every time.
- Train your billing team: Offer ongoing training for your billing staff to ensure they understand the nuances of proper coding and stay current with industry updates. Encourage them to take certification courses for coding if possible.
- Audit your coding regularly: Conduct periodic audits of your billing practices to ensure that the codes being used are accurate, and that the services provided are being appropriately matched to the correct codes.
Proper coding is not just about preventing denials – it's also about safeguarding your practice’s reputation and financial health.
3. Missing or Invalid Prior Authorization
Certain procedures and treatments require prior authorization from insurance companies. Failing to obtain this authorization before delivering services can lead to automatic denials and leave your practice with unpaid bills.
Without prior authorization, many insurance companies will not reimburse for the services provided, resulting in denied claims and lost revenue. In order to ensure prior authorization:
- Verify requirements upfront: Before providing services, check with the insurance company to confirm if prior authorization is required. This should be a standard step in your intake process.
- Set up reminders: Use scheduling tools that send reminders to your team when prior authorization is due, helping ensure timely submission.
- Follow up on pending authorizations: Track pending authorizations and follow up as needed to make sure you get approval before moving forward with the procedure.
Staying ahead of authorization requirements can prevent future denials and delays, allowing you to focus on providing the best care possible.
4. Out-of-Network Billing Issues
Out-of-network billing can be tricky. Often, private practice owners will inadvertently bill clients for services provided by out-of-network providers, or clients may not be aware they are seeing an out-of-network provider until after the service is rendered.
When this happens, clients may be surprised by large out-of-pocket costs, and insurance companies may refuse to reimburse you for services provided outside of their network. This could lead to client dissatisfaction and financial instability for your practice, but it can be avoided when you:
- Clearly communicate network status: At the time of booking, make sure clients know whether your practice or the individual provider is in-network or out-of-network. This transparency can help manage expectations.
- Explore single-case agreements: If a client needs to see an out-of-network provider, consider negotiating a single-case agreement with the insurance company to cover the service.
- Provide cost estimates: For clients seeing an out-of-network provider, check their out-of-network benefits to give them a detailed cost estimate upfront. This will ensure clients are aware of potential costs.
Clear communication with clients about network status, coupled with proactive cost estimates, can minimize confusion, prevent billing issues, and increase client satisfaction.
5. Duplicate Claims
Submitting the same claim more than once can lead to denials, particularly if the claim is already under review or has been paid. Insurance companies are unlikely to pay multiple claims for the same service. Because of this, duplicate claims may cause confusion and result in payment delays, as well as additional administrative work for your practice.
In order to prevent this, we recommend you:
- Implement a tracking system: Create a robust tracking system within your practice management software to ensure each claim is only submitted once.
- Double-check submissions before resubmitting: Before submitting a claim again after a rejection or delay, verify that it hasn’t already been processed.
- Communicate with insurers: If a claim is lost or delayed, always communicate with the insurance company directly to confirm its status rather than resubmitting it immediately.
A clear and consistent tracking system will help eliminate duplicate claims and reduce administrative burden. Healthie’s direct integration with Claim.MD can help you manage the entire insurance billing process from one platform, helping you maximize your revenue while minimizing the time spent on claim resubmissions.

6. Failure to Verify Client Responsibility Insurance Coverage
Uncertainty around a client’s deductible, co-pays, or coinsurance can lead to unpaid balances, as these amounts are often missed during the billing process. If client responsibility is not confirmed at the time of service, your practice could end up with unpaid balances and issues with client satisfaction. To prevent these uncomfortable yet avoidable situations, you can:
- Use real-time eligibility checks: Before each visit, check the client’s eligibility and confirm their insurance coverage, including any deductibles or co-pays.
- Provide cost estimates upfront: Based on the verification of insurance coverage, provide clients with a breakdown of their expected out-of-pocket costs.
- Set up payment plans: If clients have high out-of-pocket expenses, offer flexible payment plans to reduce the likelihood of unpaid balances.
Verifying coverage and providing cost transparency will not only reduce billing errors but also improve the over satisfaction of your clients.
How to Reduce Medical Billing Denials
Reducing denials is an ongoing effort that involves staying updated, being proactive, and using the right tools. Here are some additional steps to further reduce medical billing denials:
- Stay Updated on Insurance Policies: Keep an eye on any changes in payer policies and denial codes, as insurance companies frequently update their rules and requirements. This will help prevent billing mistakes.
- Improve Medical Bill Customer Service: Train yourself or your staff to be proactive in addressing denied claims and disputes with insurers. A well-prepared team will be more effective at navigating the appeals process and ensuring timely resolutions.
- Understand Soft vs. Hard Denials: Soft denials can often be corrected and resubmitted, whereas hard denials may require appeals. Knowing the difference can help you prioritize claim follow-ups.
- Streamline Provider Credentialing: Ensure that your practice’s providers are properly credentialed with insurance companies. Use credentialing software to track applications and avoid delays in claims processing.
