I would think your presence in a hospital room would be covered under HIPAA and that regardless, video in which you can be identified, short of committing a criminal act, would require your signed release to use commercially (yeah, another gray area).
HIPAA specifically covers healthcare providers who generate healthcare information. Anyone else is not obliged to obey this law. Photographers, Videographers, And other members of the press are not covered by HIPAA.
Meaning that if a photographer is in a public place where they can see a hospital, they can take all the pictures they want of people coming and going from that hospital. Photographers can also take pictures of people with injuries in public like at the scene of an automobile accident.
In areas of a hospital where there is a reasonable expectation of privacy , then no, a photographer cannot take pictures without permission or consent.
