What the IOP description establishes
Start with programs iop for the owned service description, then compare the broader outpatient treatment programs scope. Together, these pages provide context for the verified definition of IOP as structured outpatient care.
MVBH describes Half Day Treatment, often called IOP, as structured outpatient care. The description applies to adults who live at home while participating in treatment. This establishes the broad setting, but not the internal steps of a treatment plan review.
The evidence does not state when reviews occur, who attends, what records are used, or how decisions are documented. It also does not define how a review relates to individual or group services. Treat those details as questions for MVBH, not as features implied by the program name.
