10/01/2021 Update

On October 1st, 2014, AHCCCS launched a new inpatient hospital reimbursement methodology utilizing All Patient Refined, Diagnosis-Related Groups or APR-DRGs. The APR-DRG payment methodology is better aligned with the agency’s focus on improved patient care and health outcomes for its members, and incentivizes quality of care. This payment methodology was first rebased in 2017.

AHCCCS is partnering with Guidehouse Consulting to conduct a 2021 rebase of the APR-DRG reimbursement methodology. Currently, AHCCCS is on Version 34 of 3M's DRG software, and is looking to move to Version 38 of the software. The rebase process is underway, with an expected completion of April 30th, 2021.
