Learn about the HCPCS code J2790 for injection, Rho D immune globulin, human, full dose, 300 micrograms (1500 i.u.).

## **What is the HCPCS code J2790 for?** The HCPCS code J2790 is one of may J codes. J codes are all related to injections. For J2790, it's meant to denote the intramuscular injection of Rho D immune globulin for humans, specifically a full dose of 300 micrograms (1500 i.u.). This type of injection was created for the benefit of pregnant mothers. This medicine prevents immune reactions in Rh-negative people who may have been exposed to Rh-positive blood. In the context of pregnant mothers, Rh-negative mothers can have Rh-positive fetuses, which can lead to Rh incompatibility between the two. This is bad because if that's the case, the newborn might suffer from a hemolytic disease. Through the intramuscular use of this injection, the immune system of the Rh-negative pregnant mother can be prevented from producing antibodies that attack the red blood cells of Rh-positive fetuses, especially future Rh-positive fetuses.
