About ICD-9-CM 649.33

The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as O99.111 (Other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating pregnancy, first trimester), O99.112 (Other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating pregnancy, second trimester) and O99.113 (Other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating pregnancy, third trimester).
