What it is:
Box 18 is where you would refer to an inpatient stay and indicates the admission and discharge dates associated with the service(s) on the claim. Enter the inpatient 6-digit (MM│DD│YY) or 8-digit (MM│DD│YYYY) hospital admission date followed by the discharge date (if discharge has occurred). If not discharged, leave discharge date blank. This date is when a medical service is furnished as a result of, or subsequent to, a related hospitalization.
Therabill will use the values from the Hospitalized fields that are in the Dates section of the patient's Advanced tab to build the data for Box 18.
On the top menu bar, select Clients / Client List. Click the blue pencil for the desired client. You will now see the client information form. Click on the Advanced tab at the top of the Patient information form. In the Dates section, find the sub-section labeled Hospitalized. Enter the appropriate dates in the From and To date fields that the patient was hospitalized.
