Question

You need to know some important information regarding medication you’re currently taking. After we reviewed our records, we find that approval for coverage of your medication, Nexium 40MG, is about to expire on August 26, 2013.

Please understand in order to renew this medication, you will need to contact your physician and have someone in the physicians’ office contact us at 662-555-9876 so we can decide if your medicine qualifies for continuing coverage. Once a decision has been made, we will let your physician and you know. This process could take several days, so you need to address this situation immediately if you desire to continue on this medication.

If you are no longer taking the medication listed in this letter then no action is necessary on your part.

Sincerely,

Answer 1

physicians’ >> one physician? physician's

The rest is great!
