285.9
ICD-9-CMThis code signifies a general diagnosis of anemia without further specification of its type or underlying cause. It indicates a reduction in red blood cells or hemoglobin, leading to decreased oxygen-carrying capacity in the blood, but the specific etiology remains unknown or unrecorded.
Utilize this code when the medical record clearly states "anemia" but provides no additional details regarding its classification (e.g., iron deficiency, pernicious, aplastic). This is appropriate when initial workup for anemia is pending, or when the physician has not yet determined the specific type. Documentation should explicitly lack further diagnostic specificity.
