If you mean do I see inpatient admissions on my inpatient until at 3pm, then absolutely not. Any admission that hits the floor after 12pm gets seen the next day. Now on days when I am on home call until 11pm, I will sometimes see admissions via telepsych until ~3pm if I am bored. But seeing those admissions takes away from the wRVU pool for my colleagues the next day, so I don't do it often. Usually just a judgement call.
If you mean inpatient consults in the hospital, it would vary by institution. In residency, we would see any and every consult that came across before 5pm. I still get flashbacks of the consult on the other side of the hospital that came across at 4:57pm for "Patient yelling. Wants to talk to psych." At my community hospital now, it is completely up to the discretion of the physician on the consult service. Mon-Fri the consult attending will see any consult that comes in and usually lives at the hospital 7:30am-7pm most days. On the rare weekends I cover the consult service, I see 10 consults then cap it until the next day. Whatever doesn't get seen Sunday rolls into Monday. Weekends can be very busy though, up to 18-20 consults per day at times.
