Question: I've been linking the cancer's ICD-9 code to the oncologist's phlebotomy services and getting denials. What ICD-9 code should I use? Answer: When oncology practices have trouble getting paid for the oncologist's phlebotomy services, the reason is usually improper ICD-9 codes. Many oncology coders mistakenly treat therapeutic phlebotomy coding the same as chemotherapy treatment coding by linking cancer diagnosis codes to a phlebotomy procedure code, such as 99195 (Phlebotomy, therapeutic [separate procedure]).

Instead, you should use one of these ICD-9 codes:
In addition, make sure you're supplying a sufficient amount of medical documentation. The patient's record should include details of the condition the oncologist treated and the date of the service. The documentation should also indicate either the patient's red blood cell mass or a pre-phlebotomy hematocrit of more than 60 percent.
