Anemia is usually classified based on the size of RBCs, as measured by the mean corpuscular volume (MCV). Anemia can be microcytic (MCV typically less than 80 Î¼m3 [80 fL]), normocytic (80 to 100 Î¼m3 [80 to 100 fL]), or macrocytic (greater than 100 Î¼m3 [100 fL]).
Official coding guidance for the H1N1 influenza doesnât yet exist and there is no current ICD-9 code specifically for it. Until a more specific code is developed, coders should use the 487 influenza codes. For rapid nasal swab, report code 87804-QW (Infectious agent antigen detection by immunoassay with direct optical observation; Influenza). To code for the antiviral drugs, report either HCPCS G9019, Oseltamivir phosphate, oral, per 75 mg (TamifluÂ®) or G9018 Zanamivir, inhalation powder, administered through inhaler, per 10 mg (RelenzaÂ®).
