Question:
First course of treatment/Other therapy--How do you code medical marijuana when given as "treatment?" See Discussion.
Discussion:
The patient has gastric cancer and the physician prescribed medical marijuana as treatment. SEER*Rx says marijuana is ancillary as a psychoactive cannabinoid and antiemetic and advises not to code it. The physician specifically wrote "treatment with" in the record. Should it be coded as Other (Code 1) under Other Therapy?
Answer:
Do not code as treatment. Enter the information regarding the use of marijuana in a text field. There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease. At this time, marijuana is used to treat side-effects (such as nausea, vomiting, and pain) and to help increase appetite which helps patients tolerate standard therapies.
