Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the R70 range.

Reticulocytosis

An increase in circulating RETICULOCYTES, which is among the simplest and most reliable signs of accelerated ERYTHROCYTE production. Reticulocytosis occurs during active BLOOD regeneration (stimulation of red bone marrow) and in certain types of ANEMIA, particularly CONGENITAL HEMOLYTIC ANEMIA.

About the R70 Code Range

These are abnormal blood examination findings without a diagnosis. They involve a raised erythrocyte sedimentation rate or plasma viscosity outside its reference range.

R70.0 identifies the raised rate. R70.1 identifies abnormal plasma viscosity.
