Effective 1 February, 2013, the TriCare Pharmacy copays increased anywhere from $4 to $19 depending on the medication and type of service (network pharmacy or mail order). If you are fortunate enough to be near a base, you can still get your medications at no cost (if they stock it). A "small" increase, but an increase never the less.
There are more TriCare cost increases coming in the future, so be prepared for them.
