Icf Discharges

If you have a resident that is admitted ICF MEDICAID, NOT SKILLED, you have 14 days to do the initial assessment, say they leave on their 7th day,and goes home , you code their discharge 8, for discharged prior to assessment, so you would NOT do their MDS since they were only there 7 days, they are NOT SKILLED, is this correct? We have always done ICF this way , if they leave and go home prior to their 14th day, we understand that Medicaid pays by the Quarter unlike Medicare Part A, we always do a Skilled 5 day assessment / MDS even if the person was only there 1 day. We seem to be having a disagreement on this. Can use any help that you can offer. Hurry!!!!!!:argue:
