    ICD-10-CM Code For Iron Deficiency Anemia: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D50 includes diagnoses of iron deficiency anemia caused by inadequate iron stores, chronic blood loss, or impaired iron absorption, covering stages from iron deficiency without anemia to severe iron-deficiency anemia. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as laboratory-confirmed low hemoglobin and hematocrit with corresponding iron studies, identification of underlying causes like gastrointestinal bleeding or malabsorption, and assessment of disease severity and chronicity. Accurate coding within the ICD-10-CM D50 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM D50: Iron Deficiency Anemia Overview

    The diagnoses in this group represent iron deficiency anemia, a condition characterized by reduced hemoglobin production due to insufficient iron. These codes target hematologic disorders affecting red blood cell production and oxygen-carrying capacity. Accurate coding matters for reimbursement because it documents clinical severity and supports correct claim processing.

    When to Use

    Use a code from this group when clinical evaluation documents iron deficiency as the cause of anemia, confirmed by laboratory testing and clinical assessment. Apply the code that best reflects the documented severity, associated complications, and any identified underlying cause.

    Typical Clinical Scenarios

    • A premenopausal woman presents to primary care with months of progressive fatigue, heavy menstrual bleeding, and palpitations; lab tests show microcytic hypochromic anemia with low serum ferritin and transferrin saturation consistent with iron deficiency from chronic blood loss. The clinician documents nutritional iron deficiency anemia related to menorrhagia as the cause of her symptoms and initiates iron therapy and gynecologic evaluation. Typical codes: D50.0, D50.9
    • An elderly man is admitted to the hospital for symptomatic syncope and is found to have acute blood loss from a bleeding peptic ulcer; labs reveal a drop in hemoglobin with iron-deficiency features on iron studies after stabilization. Because the anemia is attributable to recent gastrointestinal blood loss and iron deficiency, the inpatient problem list includes an iron deficiency anemia diagnosis concurrent with treatment of the ulcer. Typical codes: D50.0, D50.8
    • A middle-aged patient with chronic kidney disease being followed in clinic has persistent microcytic anemia unresponsive to erythropoiesis-stimulating agents; iron studies demonstrate depleted iron stores and the clinician attributes the anemia to nutritional iron deficiency complicating the chronic disease management. This is documented as a chronic iron deficiency anemia contributing to the patient’s comorbidity profile and guides ongoing iron repletion strategies. Typical codes: D50.1, D50.9
