ICD-10 & ICD-9 codes

This is not meant to be an exhaustive list of ICD-9 codes; rather, its purpose is to be a general yet inclusive enough list for general hematology/oncology use. That is, when one needs to find an ICD-9 to justify a lab test, diagnostic study, or medication, this should generally be sufficient. I suggest you use this is by using the search function in your web browser (for example, by pressing Ctrl + F) and typing in the general term you're looking for, such as anemia.
