Medicare Cost Reporting Integrity for Cost Plan H6161

This report provides the results of an Office of Inspector General (OIG), Office of Audit Services (OAS) review titled, "Medicare Cost Reporting Integrity for Cost Plan H6161 for the Period January 1, 1998 through December 31, 1998."  The purpose of our review was to evaluate costs claimed for reasonableness, allowability and allocability, and to test paid claims data for duplicate claims.  We found the cost reporting process to be generally adequate and that the Medical Associates Health Plans (MAHP) was detecting and adjusting most duplicate payments.  There were, however, a small number of claims (totaling $1,006), which were paid by both MAHP and the carriers.  We recommended that MAHP revise the 1998 cost report to eliminate the duplicate payments and continue to closely monitor duplicate claims.
