They donu2019t have electronics to hand out for you to do it electronically. Some will allow it to be done on line but they MUST have a secure data portal. Data like your pharmacy allows the practice to know where to call in scripts. In my town there are perhaps 7 each of Walgreen's, CVS etc. and a myriad of independent pharmacy. There are at least 4 of each on the same street 1/3 of a mile apart.Imagine you need a script and the practice calls it into the wrong pharmacy (many are electronically sent these days). If the prescription goes to the wrong pharmacy you will likely be unable to get it.In todayu2019s insurance world your insurance may require a certain pharmacy. Two or more major chains may be right next to each other.Such data makes your care easier and less prone to error.
