Code Description

ICD-10 R71.8 is a billable code used to indicate a diagnosis of other abnormality of red blood cells.

Key Diagnostic Point:

The ICD-10 code R71.8 is used to classify other abnormalities of red blood cells that do not fall under more specific categories. This may include various atypical findings in red blood cell morphology, such as poikilocytosis, anisocytosis, or the presence of abnormal red cell inclusions. These abnormalities can be indicative of underlying conditions such as hemolytic anemia, nutritional deficiencies (like iron, vitamin B12, or folate), bone marrow disorders, or chronic diseases. Clinically, patients may present with symptoms such as fatigue, pallor, shortness of breath, or jaundice, depending on the severity and underlying cause of the red blood cell abnormality. Laboratory findings may include abnormal complete blood count (CBC) results, peripheral blood smears showing atypical red blood cell shapes or sizes, and reticulocyte counts that may indicate bone marrow response. Accurate identification and coding of these abnormalities are crucial for appropriate management and treatment of the underlying conditions.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions that can cause red blood cell abnormalities
  • Need for precise laboratory findings to support coding
  • Differentiation from other hematological conditions
  • Potential overlap with other ICD-10 codes

Audit Risk Factors

  • Insufficient documentation of laboratory findings
  • Failure to specify the underlying cause of the abnormality
  • Inconsistent coding with clinical notes
  • Misinterpretation of abnormal lab results
