Enrollment in an MMCP can be verified by checking the Medicare Enrollment Query (MEQY)
on the HI/SMI Query Response (HIQR) Screen (see MSOM QUERIES 008.001). The dates of enrollment and disenrollment can also be obtained from the MEQY. If
termination information is not shown, assume that the individual is still enrolled
in the MMCP.
If there is no enrollment information on the MEQY or a discrepancy in the dates shown,
contact the appropriate CMS Regional Office (see HI 00801.143C.) for assistance in obtaining the necessary evidence.
