Two questions:
1. Is there any wat to delete a clinic? I´ve created two -mistakes! - there´s no data on them, but don´t know how to delete them…
2. Billing information that clinic setup asks, could be modified? The field that shows a drop down list with 99 codes of billing assigment, is a table or they are pre-defined values? Could they be changed?
You could delete a clinic by removing it from the "facility" table using phpmyadmin (Administration/Database). Just be careful that you are not referencing it anywhere.
I believe the POS codes are hard-coded. You could find them easily enough with a search (e.g. “grep -r ‘Inpatient Hospital’ *”).
