Program reviews
June 11, 2020
(a) Review of State and local administration of the CHIP plan. In order to determine whether the State is complying with the Federal requirements and the provisions of its plan, CMS reviews State and local administration of the CHIP plan through analysis of the State's policies and procedures, on-site reviews of selected aspects of agency operation, and examination of samples of individual case records.
(b) Action on review findings. If Federal or State reviews reveal serious problems with respect to compliance with any Federal or State plan requirement, the State must correct its practice accordingly.
