## **What is the HCPCS code J9045 for?**
The HCPCS code J9045 is one of many J codes that designate the provision of injected medication. For J9045 in particular, what is being designated is the provision of a carboplatin injection, specifically every 50 mg of it. A carboplatin injection is a kind of chemotherapy drug that kills cancer cells, or at least slows down their growth. Doing so prevents the cancer from spreading further and increases the survival rate of the patients, which in turn may improve the quality of their health and lives.
The efficacy of this injection has been determined by numerous tests and has been found to be effective in combating certain cancers. Examples of cancers this type of injection treats include lung cancer, ovarian cancer, head and neck cancers, testicular cancer, and non-melanoma skin cancers, to mention a few.
Please note that this injection is typically administered intravenously. It can't be self-administered.
