How to choose care in Mercer County

A sensible first step is to match the level of care to the need: medically supervised detox, residential or outpatient rehabilitation, an opioid treatment program for medications for opioid use disorder, sober living, or inpatient psychiatric care. Ask what each provider actually offers rather than assuming the category covers it.

When you are choosing for yourself or someone you care for in Mercer County, call ahead to confirm current availability, intake requirements, accepted insurance or payment, and whether the program is licensed or certified. Ask what happens if someone needs a higher or lower level of care.
