Years ago, I got such a letter from CVS/GEHA/and some PBM I no longer remember the identity. My Physician wrote a letter or orally talked with a scientific officer/actuary of the above grouping. Suffice to say, someone in above group changed their mind, and the original decision negating coverage for Vascepa was reversed. I never asked my PCP what was said by him to change that decision.
Today it should be even easier for that decision to be reversed in light of info released from R-I November 10. Could there be an indication you prescribed Vascepa for that is better met by a competing medication efficacy/safety-wise, and less expensive to boot?
You should take the time; if you don't, that decision of CVS in the state you are located could affect your own(and every one elses') investment, if any....surely you understand that?
