Can I daysheet if I am not done with charges from day before?

Yes, you can daysheet even if you are not done with charges from previous day. The importance of running a daysheet is to lock in the payments and prevent them from being deleted. If a payment is deleted/voided prior to posting the daysheet, it will not show in the audit log, reports, or the Patient's Account. As for charges, you are able to run reports based on the DOS, therefore you will still be able to filter for them regardless of what daysheet(s) they were posted on.
