Health facilities: other; licensure of freestanding hyperbaric oxygen therapy facilities; provide for. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding pt. 212. TIE BAR WITH: HB 5590'26, HB 5592'26, HB 5593'26

HB 5591 updates Michigan's Public Health Code to establish licensing requirements for freestanding hyperbaric oxygen therapy facilities (which treat conditions like non-healing wounds using pressurized oxygen). It directly affects these specialized facilities by requiring them to be accredited by approved organizations (like The Joint Commission), appoint a medical director licensed as a physician or nurse practitioner, and designate a safety coordinator. Key provisions include defining terms like "qualified health professional" and mandating compliance with NFPA 99 fire safety standards. The bill does not change patient access but sets new operational standards for facility operators. (Note: This bill is pending and requires companion bills HB 5590-5593 to take effect.)
