It may be easy to find that accepts Blue Cross Blue Shield; however, specifics will vary according to each individual plan. If it is determined that patients need medically supervised detox or withdrawal management, most plans will cover that part of the treatment process; however, it may be more difficult or costly to obtain residential care under lower-tier insurance plans. Many insurance providers often require patients to seek outpatient treatment as a first means of treatment. The plan type will determine the scope of treatment. Patients who have HMO (Health Maintenance Organization) plans will face more restrictions while those with PPO (Preferred Provider Organization) plans will have a wider variety of selection. Generally speaking, individuals under the Blue Cross Blue Shield umbrella should be able to easily access some level of treatment; but they may only have part of their treatment covered, depending upon the scope and depth of their employer-based health insurance plan.
