Substance Abuse - Voluntary Help vs. Involuntary Help

[Guest dfullerton]

I have a self funded client that has implemented a drug screening process within the work place. Now they want to change the health benefits for Inpatient or Outpatient Substance abuse to 100% coverage if the individual voluntarily seeks medical help and only 50% coverage if the individual is caught in violation of the work place drug screening.

It seems to me that the individual whether voluntary or involuntary is ill and I feel that the client may be at risk for a discrimination argument in the future.

Can anyone advise if this 100 vs 50 would be legitimate or not?
