Currently the eligibility check will check according to the date it was requested (regardless of what the DOS is). Then, the user has to read the information returned to decipher if they really did have coverage on the date that they are inquiring about. Many people, especially Medicaid patients, will have coverage 1 month and not coverage the next month. Many agencies may not have the time to check the eligibility on the DOS and desire to do it at a later date and time (depending on their workflow). It would be nice to be able to select an alternate date for the eligibility check.
