What Impact Will ICD-10 Have On AR-DRG Payments?
Lack of ‘specificity’ for a certain diagnosis as
documented in the record, could have the potential of
not capturing the CC/MCC which could result in a
lower paying AR-DRG.
AR-DRG shifts could occur due to improper training
of the coding staff.
This incorrect code assignment could also potentially cause changes within
the AR-DRGs resulting in payment increases or decreases
