Medicaid: Prior Authorization Data

To comply with the CMS Interoperability and Prior Authorization final rule, the Wisconsin Department of Health Services is required to report prior authorization metrics annually. This includes a list of all medical items and services (excluding drugs) that require prior authorization, as well as data on prior authorization requests for those items and services (approvals, denials, etc.) over the previous calendar year.


Prior authorization data

Publicly reporting this data promotes transparency and accountability, helps members understand prior authorization processes, and enables providers to evaluate payer performance. In addition, metrics can be used to compare plans, programs, and payers. This is reported in March of each year, for the previous calendar year.
