A Guide for Medical Providers about CO-45 Denial Code

Life of medical practitioners dwells between providing excellent care to their patients and managing finances. Meanwhile, complicated insurance claims raise the head.  Understanding denial codes can help in managing the billing process and preventing denials.

Denials with CO-45 can have a substantial influence on a healthcare provider’s revenue cycle, potentially resulting in an average revenue loss of 2-5% for each claim.

What Is CO-45 Denial Code?

In simple words, denial code CO-45 is a claim adjustment reason number to highlight the fact that the billed amount exceeds the amount allowed under the insurance plan fee structure. The most common reasons for these denials are:

  • The healthcare provider did not update its current fee schedule according to the latest contract terms.
  • The healthcare provider did not perform insurance coverage verification of the patient before providing treatment.
  • This reason arises when a physician uses an incorrect code or modifier.
  • If the doctor did not properly document or justify the urgency of care and requirement for relevant service, this is another cause of denial
  • Identical claim submission of a claim for an alike service is a recurrent oversight, leading to a straight denial or reduced compensation.
