About Hematology & Oncology Providers
A hematologist-oncologist is a medical physician who specializes in diagnosing, treating, and managing blood disorders and cancers. They treat conditions like leukemia, lymphoma, anemia, hemophilia, and solid tumors, administering therapies like chemotherapy, immunotherapy, and blood transfusions. These specialists earn an MD or DO, complete an internal medicine residency, and undergo a three-year fellowship training program in hematology and oncology. They coordinate complex oncology treatment plans, conducting research and clinical trials to improve patient outcomes.
Finding a hematologist-oncologist's NPI number is essential for processing oncology billing, writing chemotherapy prescriptions, and requesting insurance pre-authorizations for cancer treatments. Insurance providers require the oncologist's NPI on claims to pay for consultations and cancer therapies. The NPPES registry verifies the physician's active license, board certifications, and oncology taxonomy. Checking the NPI registry helps oncology centers manage billing and helps patients confirm that their specialist is registered.
