Reducing Administrative Burden for Your Office - Prior Authorization Changes for HAP Medicare Plans

Posted: 03/12/2020

Effective immediately, prior authorization for most part B medical drugs will not be required for HAP Primary Choice Medicare (HMO) and HAP Choice Medicare (HMO) plans. Since 2019, other HAP Medicare plans have not required authorization for these drugs. Now all HAP Medicare plans will be better aligned. Note: prior authorization is still required for Botox (J0585) and Xiaflex (J0775).

HAP will review claims with dates of service January 1, 2020 to present. Appropriate action will be taken for claims with incorrect denials related to prior authorizations for these drugs.
