Hey guys, I work in Wisconsin and it has been the State Department of Health's policy that pairs of doors on the corridor must have automatic closing on the inactive leaf. For example, at a patient bedroom, if there is a small inactive leaf that is used just to move large beds or other equipement in and out, it must have a closer, which means automatic flush bolts and a coordinator as well. If they want to hold it open, then they require magnetic holders tied to the fire alarm.
IBC 2009 starts to address this issue, but doesn't do a very good job. 1008.1.9.4 Bolt locks. Exceptions: 5. Where a pair of doors serves patient care rooms in Group I-2 occupancies, self-latching edge- or surface-mounted bolts are permitted on the inactive leaf provided that the inactive leaf is not needed to meet egress width requirements and the inactive leaf contains no doorknobs, panic bars or similar operating hardware.
You will notice the "self-latching" part of that exception. The purpose of this is so that nurses or other employees don't have to deal with latching the inactive leaf as they are going down the hall checking for patients and closing doors. However, from a hardware standpoint, self-latching would usually mean a coordinator as well, to prevent damage.
One of the big problems we run into with hospital work is all of the different agencies involved with certification. They can make up a lot of rules that affect even the door hardware. It is not just the local AHJ that is involved. This might be where you are running into a bathroom door being required to "resist the passage of smoke".
