No, you need an appointment. This is a doctor's office with medical specialists, not an urgent care clinic. However, there is a Patient First Urgent care center at 4924 Campbell Boulevard Suite 125 Baltimore, MD 21236-5921 that is extremely close to this office that does take walk-ins.
I don't think you need an appointment. They are opened Mon - Thurs. from 8am to 10pm and weekends from Friday 8am to Sunday 10pm (weekends are opened 24 hours).
Yes, emergency services any way, any time.
