Effective Dates Correction to the APR-DRG Temporary Weight Increases

July 27, 2020

MassHealth is aware that the effective dates for temporary weight increases to certain APR-DRGs were misaligned with the dates set forth in Amendment 3 to the Rate Year 2020 Acute Hospital RFA. This error has resulted in claims being underpaid due to lower, pre-amendment weights. MassHealth has corrected the error and reprocessed all of the impacted claims. All adjusted claims will appear on this or future Remittance Advices.

The APR-DRGs involved were: 004, 005, 113, 120, 121, 130, 131, 133, 134, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 720
