The Indiana Health Coverage Programs (IHCP) has identified a claim processing system issue affecting claims for HCPCS codes G0477, G0478, and G0479. These codes were deleted by CMS effective December 31, 2016, but, in error, were not end-dated in CoreMMIS. This error was corrected January 20, 2017. Claims for HCPCS codes G0477, G0478, and G0479 with dates of service (DOS) from January 1, 2017, through January 20, 2017, that paid in error will be mass adjusted. Adjustments should begin appearing on the provider Remittance Ad-vice (RA) beginning April 25, 2017, with Claim IDs (formerly Internal Control Numbers) that begin with 52 (mass replacements non-check related). If a claim was overpaid, the net difference appears as an accounts receivable. The accounts receivable will be recouped at 100% from future claims paid to the respective provider number.
