Clearinghouse MRO

Q. What are a medical review officer’s (MRO’s) responsibilities for reporting information to the Clearinghouse?

A. Within two business days of making a determination or verification of a Department of Transportation (DOT)-approved drug test, an MRO must report:

  • Verified positive, adulterated, or substituted controlled substances test results; or
  • Refusal-to-test determination.
The MRO must report any changes of a verified drug test within one business day of making any changes to the reported results.
