Providers Should Begin Including ICD Indicators on CMS-1500 Paper Claims
CMS-1500 paper claims received on or after September 22, 2014, must include the ICD indicator “9” when they include a diagnosis code in the Diagnosis or Nature of Illness or Injury field (Box 21). In anticipation of this requirement, providers should start including the ICD indicator “9” on claims immediately.
No ICD indicator is required if the claim is submitted without a diagnosis code. Claims with a diagnosis code received on or after September 22, 2014, that do not include the ICD indicator “9” will be returned via the Resubmission Turnaround Document (Form 65-1).
For more information about the ICD indicator requirement, please see the Claim Form Updates page of the Medi-Cal website.
