Care levels at Ascension Columbia St. Mary's Hospital - Ozaukee - Behavioral Health
The facility offers a continuum of care across multiple levels — Inpatient, PHP, MAT, Dual Dx — which means it can, in principle, hold a patient across the arc of a typical treatment episode. The practical question is whether it is genuinely strong at each level, or whether one level is the core business and the others are secondary. The level-of-care question is where a lot of misaligned placements happen — a patient who needs residential ends up in IOP, or vice versa. The protection is a clinical assessment outside the facility's admissions team.
