R71.0

Precipitous drop in hematocrit

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R71.0 is a billable code used to indicate a diagnosis of precipitous drop in hematocrit.

Key Diagnostic Point:

A precipitous drop in hematocrit refers to a rapid decrease in the proportion of blood volume that is occupied by red blood cells. This condition can indicate various underlying health issues, including acute blood loss, hemolysis, or bone marrow suppression. Clinically, patients may present with symptoms such as fatigue, weakness, pallor, and shortness of breath, which are indicative of anemia. Laboratory findings typically reveal a hematocrit level significantly below the normal range, which varies by age and sex. The drop can be acute, occurring over hours to days, or chronic, developing over weeks. Identifying the cause of the drop is crucial, as it can lead to serious complications if not addressed promptly. Common causes include gastrointestinal bleeding, trauma, or conditions like aplastic anemia or hemolytic anemia. A thorough diagnostic approach often involves a complete blood count (CBC), reticulocyte count, peripheral blood smear, and possibly bone marrow biopsy to ascertain the underlying etiology.
