State Auditor Hector Balderas' office says the Human Services Department provided it with an audit report that had been altered to remove a conclusion that auditors found no "credible evidence of fraud" in a review of case files for mental health providers under investigation for potential overbilling and fraud.
Balderas obtained a subpoena last week from a Santa Fe judge to try to shed more light on the alterations.
Balderas said in court filings the department's failure to provide a complete version of the report — as required by a court order — jeopardized work his office is doing related to the state's freeze on provider Medicaid payments.
A department spokesman said the report change was made because it's the agency's sole responsibility to determine if there's evidence of fraud.
