PI 16 – Claim Lacks Information Needed for Adjudication

The PI-16 denial code indicates that the payer cannot fully process the claim because required information is missing, incomplete, or invalid. The PI (Payer Initiated) group code identifies an adjustment initiated by the insurance payer rather than a contractual obligation or patient responsibility.

Providers should review the claim carefully, identify the missing information, and submit a corrected claim when appropriate.
