Prior Authorization Update: Medicare Retrospective Authorizations

Date: 11/28/16

MHS Health Wisconsin is committed to delivering cost-effective, quality care to our members.  This effort requires us to ensure that our members receive only treatment that is medically necessary according to current standards of practice.  Prior Authorization is a requirement and a condition of payment for some services as defined in the MHS Health Wisconsin Medicare Provider Manual. 

Effective January 1, 2017, MHS Health Wisconsin will no longer be accepting requests for retrospective authorizations.  Retrospective requests are requests received after a service has been provided. Under Part C (Medicare Advantage) rules, once a service has been rendered without obtaining prior authorization it is considered to be post-service even if we have not received a claim.  Post-service, you may submit a Request for Payment.
