CO-252 Denial Code: Missing Documentation or Attachments

What is CO-252 Denial Code

CO‑252 Denial Code is used by payers to indicate that a claim has been denied due to missing documentation or attachments that support the medical necessity of the services billed. This denial signifies that the payer requires further evidence to justify the claim, which can include clinical notes, authorizations, or specific forms required by the insurance plan. When such documentation is lacking, it directly affects the reimbursement process and can lead to delays in payment.

Various payers may have different requirements regarding what constitutes sufficient documentation. For instance, a private insurer may require specific pre‑approval documentation for certain procedures, while Medicare might have its own set of documentation standards. Understanding the documentation expectations of each payer is crucial for healthcare providers to avoid this denial and ensure timely payment.
