Using Medicare, senior adults in California who are struggling with addiction can avail themselves of many drug and alcohol rehab centers which are covered by their health coverage. Many outpatient facilities around the CA. area are covered through Medicare, but seniors will also find that Medicare provides coverage for hospitalization required in the course of drug and alcohol rehab such as an inpatient or residential program. Medicare provides coverage for a full array of services for drug and alcohol rehab in California such as counseling, training, followup programs, and other treatment solutions as deemed necessary by doctors while in treatment. One of the things which Medicare plans do not cover is methadone maintenance treatment plans in the case of opiate addiction, so senior adults will need to find a drug rehabilitation center covered by means of Medicare that addresses opiate dependence through other means. Seniors with Medicare can consult with their doctor or Medicare directly to differentiate what types of drug and alcohol rehab centers are approved.
