The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R71 includes nonspecific laboratory and microscopic abnormalities of red blood cells such as anisocytosis, poikilocytosis, or abnormal erythrocyte indices that are reported without a confirmed disease diagnosis. These ICD-10-CM diagnosis codes are used to document abnormal red blood cell findings identified on peripheral smear or automated testing, capturing diagnostic uncertainty and the need for further evaluation. Accurate coding within the ICD-10-CM R71 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.
