In simple words: Rhophylac is a medicine given as an injection into a muscle or vein. It prevents people with Rh-negative blood from developing a harmful reaction if they are exposed to Rh-positive blood.

This code represents 100 international units (IU) of Rhophylac, a brand of Rho(D) immune globulin (human), administered either intramuscularly or intravenously. It is used to prevent an immune response to Rh-positive blood in patients with Rh-negative blood.

Example 1: An Rh-negative pregnant woman receives Rhophylac during her pregnancy to prevent sensitization to potential Rh-positive fetal blood., An Rh-negative patient receives a transfusion of Rh-positive blood and is administered Rhophylac to prevent the formation of antibodies against the Rh factor., A non-splenectomized adult with chronic Immune Thrombocytopenic Purpura (ITP) who is Rh-positive receives Rhophylac intravenously to increase platelet counts.

Documentation should include the patient's Rh status, the reason for administration (e.g., pregnancy, transfusion, ITP), the dosage administered, the route of administration (IM or IV), and the date and time of administration.
