Hematologists frequently handle intricate treatment plans, especially when also treating cancer patients. Sometimes a hematologist doubles as an oncologist, while other cases involve separate specialists. This overlap demands precise billing codes to capture each treatment’s nuances—whether it’s a new procedure, a recurring condition, or specialized medication. Proper documentation is essential to accurately reflect each physician’s role and avoid billing confusion, ensuring all aspects of patient care are covered and reimbursed without unnecessary denials.
