Handling the most frequently occurring medical billing denial codes is a critical aspect of effective revenue cycle management in healthcare. Denied claims can lead to delayed payments, increased administrative burden, and potential revenue loss for healthcare providers.

When selecting the best medical billing services, it’s essential to consider factors such as the size of the practice, specific needs, budget constraints, and the level of integration required with other systems.

In this article, we will explore common denial codes, the reasons behind their occurrence, and strategies to effectively address and prevent them.

Understanding Common Denial Codes:

Insufficient Documentation (Code 22):

  • Reason: Lack of necessary supporting documents or incomplete medical records.
  • Strategy: Implement comprehensive documentation procedures, conduct regular staff training, and utilize electronic health record (EHR) systems to ensure completeness.

Duplicate Billing (Code 18):

  • Reason: Submitting the same claim more than once for the same service.
  • Strategy: Implement automated systems to identify and prevent duplicate claims, conduct regular audits, and educate staff on proper billing procedures.

Claim Not Covered by Payer (Code 96):

  • Reason: The specific service or procedure is not covered by the patient’s insurance plan.
  • Strategy: Verify patient insurance coverage prior to providing services, communicate coverage limitations to patients, and establish clear billing communication channels.

Incorrect Patient Information (Code 16):

  • Reason: Errors in patient demographic details or insurance information.
  • Strategy: Implement stringent data entry protocols, regularly update patient information, and leverage technology for real-time eligibility verification.

Addressing Denial Codes Effectively:

Implement Robust Training Programs:

  • Conduct regular training sessions for billing staff to stay updated on coding changes, documentation requirements, and compliance standards.

Utilize Technology:

  • Invest in advanced billing software and EHR systems that can automate claim submission, identify errors, and provide real-time eligibility verification.

Conduct Regular Audits:

  • Establish a routine audit schedule to identify and rectify billing errors promptly. This proactive approach can prevent denials before claims are submitted.

Enhance Communication with Payers:

  • Establish open lines of communication with insurance providers to clarify coverage policies, resolve disputes, and stay informed about any changes in billing regulations.

Monitor Key Performance Indicators (KPIs):

  • Track denial rates, analyze trends, and use KPI data to identify areas for improvement. This data-driven approach can help in implementing targeted solutions.

Prevention is Key:

While effectively addressing denials is crucial, preventing them in the first place should be a primary focus. By implementing a comprehensive approach that includes training, technology, and proactive auditing, healthcare providers can significantly reduce the frequency of common denial codes. 

This not only improves cash flow but also enhances the overall efficiency and reliability of the revenue cycle management process.


In conclusion, handling the most frequently occurring medical billing denial codes requires a multi-faceted approach that combines education, technology, and proactive monitoring. 

By addressing the root causes of denials and implementing preventive measures, healthcare providers can optimize their revenue cycle and ensure timely and accurate reimbursement for the services they provide.
When choosing the medical coding services, it’s essential to consider factors such as the service provider’s experience, certifications, compliance practices, and technology solutions.

Additionally, reviewing client testimonials, assessing the provider’s ability to handle specific coding requirements for different specialties, and evaluating their security measures are crucial steps in selecting the right medical coding service for a healthcare organization.
