Junglegirlsue,
The doctor is probably referring to drugs called erythropoiesis stimulating agents or ESAs (brand names: Epogen, Procrit, Aranesp), which are not new but are used to increase red blood counts. There has been a lot of
discussion about Medicare's coverage for these drugs. It can be very expensive for a patient to pay for them when insurance coverage is denied.
