What is the CO 39 Denial Code?


Denial CO 39 indicates that services were denied at the time authorization or pre-certification was requested. In the complex world of medical billing, some carriers necessitate obtaining prior authorization for certain procedures, either specific ones or sometimes even all procedures. These requirements can be both carrier and procedure-specific. 

This denial code is pivotal for medical professionals, as it underlines the significance of securing proper authorization before delivering healthcare services. Notably, the onus of obtaining this authorization falls on the medical provider, such as a surgeon, and not the patient. 

Delving into CO 39: Why Does It Occur? 

  • Authorization/Referral Problems: Some carriers insist on receiving prior authorization before certain services, especially surgeries. Each carrier might have its specific set of procedures for which this authorization is required. 
  • Patient Data Entry Issues: Always ensure the correct entry of patient data. For instance, if the patient's name on the Medicare card is "Bertha P. Smith", then any slight deviation like entering "Patti Smith" could trigger this denial. 
  • System Checks: Before taking any action on a denial, always check the patient’s data system for any relevant note entries related to the date of service and the procedure in question. Peruse the entire notes to ensure that the claim hasn't been sent for reprocessing already. 
  • Authorization Validation: Always pull out the original file to validate if there's an authorization number for the procedure. If an authorization is found, ensure it encompasses the procedure, checks for diagnostic testing, and sees the number of covered visits and the covered period. 


Strategies for Preventing the CO 39 Denial Code 

  • Prior Authorization and Pre-certification: Understanding the difference is crucial. While they are sometimes used interchangeably, most often they refer to the process by which a patient gets pre-approved for a specific medical procedure or prescription drug. On the other hand, “pre-certification” might be used to describe the process by which a hospital informs an insurance company of a patient's impending admission. 
  • Regular Training: Impart regular training to staff members to instill the importance of accurate data entry and the nuances of acquiring prior authorization. 
  • Stay Updated: As protocols and requirements can change, staying updated is key. Ensure that you're always working with the latest guidelines from insurance carriers. 
  • Efficient Request Processing: If a prior authorization request gets denied, it's imperative to understand why. Often, the reason for the denial can be rectified, either by providing more comprehensive documentation or by addressing the specific concern raised by the insurance company. 
  • Right to Appeal: While providers have the right to appeal a denial, sometimes it might be more pragmatic to submit a new request, especially if the cause of the initial denial can be addressed. 

In conclusion, adeptly navigating the maze of insurance denial codes like CO 39 ensures healthcare entities can optimize their billing efficiency and enhance patient trust. Armed with these insights, medical professionals can proactively address and prevent such denials, ensuring smoother operations and consistent revenue streams.
