After Hours Care – In the event of a medical emergency, always dial 911. DTC takes telephone inquiries from 8 a.m. to 12 p.m. and 1:30 p.m. to 4:30 p.m. on Monday thru Friday. In the event that you have an urgent medical question outside of these business hours, you may follow the promptings to speak to the on-call provider. Please note, matters deemed non-urgent may incur a fee for utilizing the on-call phone if the matter could have been handled during regular hours.
