2013 ICD-9-CM Diagnosis Code 285.9 : Anemia, unspecified

subnormal levels or function of erythrocytes, resulting in symptoms of tissue hypoxia.
(a-NEE-mee-a) A condition in which the number of red blood cells is below normal.
A reduction in the number of red blood cells per cu mm, the amount of hemoglobin in 100 ml of blood, and the volume of packed red blood cells per 100 ml of blood. Clinically, anemia represents a reduction in the oxygen-transporting capacity of a designated volume of blood, resulting from an imbalance between blood loss (through hemorrhage or hemolysis) and blood production. Signs and symptoms of anemia may include pallor of the skin and mucous membranes, shortness of breath, palpitations of the heart, soft systolic murmurs, lethargy, and fatigability.
ICD-9-CM 285.9 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 285.9 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
