Here is the information I found by searching on the web: J2790 Rho(D), injection, immune globulin, human, Per 300mcg J2792 Rho(D), injection, immune globulin, human, intravenous, Per 100 IUs So, J2792, would be the code used for WinRho or a similar product and J2790 used for the 300mcg dose of Rhogam. We don't give WinRho here so we only use J2790.
