5 Common Medical Billing Errors and How to Avoid Them

Medical billing procedures and coding systems present complex complications for proper management and consolidation. A single minor billing mistake has the power to trigger claim rejections which can result in legal costs and reduced patient care while leading to lost revenue. Your practice reimbursement will increase when you understand medical billing procedures and implement new strategies to prevent billing errors.

Medical billing mistakes in the United States healthcare industry result in annual prices reaching billions of dollars at the same time as professionals consider 80% of clinical bills to include at least one billing mistake.

This article explains each of the five main medical billing errors and demonstrates how to prevent billing mistakes from occurring in your healthcare practice.

The Impact of Medical Billing Errors

An understanding of broad impacts is essential before we examine particular errors. Medical billing errors affect multiple stakeholders:

• Healthcare Providers: Face delayed payments, increased administrative costs, and potential legal issues
• Patients: Experience frustration, financial strain, and delayed access to care
• Insurance Companies: Deal with increased processing time and administrative burden
• Healthcare System: The healthcare system suffers from both operational cost increases and inefficient processes because of these errors.

Healthcare practices experience substantial revenue decline from denied claims since roughly 50-65% of denied claims go reworked while the average cost to address rejected claims stands at $25.

Coding Issues or Errors

Not keeping up with the latest medical coding guidelines which keep changing constantly can impact your practice’s reimbursement process as using an outdated code leads to claim denial. Moreover, if your staff enters a wrong code incorrect date, or incorrect patient name, it will automatically lead to a coding mistake and increase the chances of claim rejection re-claim submission, and delayed reimbursement.

Common coding errors include:

• Upcoding: Medical providers submit invoices for higher-cost procedures than those delivered
• Downcoding: Healthcare providers reduce their service charges when they fear an audit investigation.
• Incorrect modifier usage: Misapplying or omitting necessary modifiers
• Outdated codes: Using discontinued CPT or ICD-10 codes

Medical billing errors stemming from coding mistakes represent thirty percent of all billings and lead to healthcare practices losing between three and five percent of their revenue on average.

Missing Information

Overlooking a piece of missing information is one of the most common medical billing errors most practices encounter. Missing information increases your chances of receiving a claim rejection. Basic information such as date of birth or gender if left blank, claims can be denied. So, ensuring the highest accuracy while claim filing is of utmost importance. Your staff must double-check all the claims and fill in all the required fields before the final claim submission.

Critical information commonly missed includes:

• Insurance policy numbers
• Prior authorization numbers
• Referring physician information
• Place of service codes
• National Provider Identifier (NPI) numbers

Research shows that claims with missing information have a 40% higher rejection rate compared to complete claims.

Missed Filing Deadlines

Sometimes, even if your staff has filed your practice’s claims accurately, they forget to submit them within the deadline, increasing the risk of claim rejection. This is a common medical billing error that occurs due to billing loads and negligence of your billing staff. Providers must have enough billing staff if they have an in-house billing team or outsource to a reliable medical billing company to avoid sending claims after the end date.

Filing deadline guidelines:

• Medicare: 12 months from service date
• Medicaid: Varies by state (typically 90-365 days)
• Private insurers: Usually 90-180 days
• Workers’ compensation: Varies by state

Duplicate Billing

When your billing staff bills the same procedure several times, it creates room for duplicate billing. This leads to increased medical costs and results in re-submission of the claim and therefore, rework and delayed payment collection. The consequence of duplicate billing can also be losing a patient’s trust in your healthcare practice. This issue can be prevented with prompt chart audits.

Common causes of duplicate billing:

• Multiple staff members processing the same claim
• System glitches in practice management software
• Lack of communication between departments
• Improper merger of patient records

Unbundling Medical Procedures

When there is a single code for an entire group of medical procedures, but separate codes have been used for linked procedures, it is known as unbundling. This may be an intentional or unintentional coding issue that increases a patient’s medical bills and lead to penalties along with reputational loss.

How can you avoid these common medical billing errors?

• File medical claims within deadlines. 
• Keep up with medical billing and coding trends.
• Hire a professional medical biller or outsource to a medical billing company
• Ensure double-checking while filing claims 
• Maintain accurate Electronic Health Records
• Ensure a service is not billed more than once
