So the pharmacy I'm the SP at got just got a letter from CVS Caremark that apparently we are not authorized to bill "complex compounds" as per our provider agreement. This means compounds containing bulk powders, dissolution of capsules/tablets, etc. Letter requests that we cease and desist billing compounds with those ingredients and that we reverse the claims that we already billed, filled, and gave to the patient. Is this the way CVS Caremark is going about in preventing pharmacies from billing compounds? I know ExpressScripts already attacked compounding pharmacies by refusing to cover bulk powders.
