Single 500 mg dose of fluorouracil chemotherapy supplied by injection

This code represents the administration of 500 milligrams of fluorouracil, an antineoplastic antimetabolite chemotherapy drug. Fluorouracil interferes with DNA and RNA synthesis, inhibiting cell growth and proliferation, and is commonly used in the treatment of various cancers.

Use this code when reporting the supply of 500 mg of fluorouracil administered to a patient. This typically applies to oncology treatments for solid tumors such as colorectal, breast, gastric, pancreatic, and head and neck cancers. Documentation should clearly state the drug administered, the dosage in milligrams, and the route of administration.

• This code represents 500 mg of the drug. If a different dosage is administered, report the appropriate number of units (e.g., 2 units for 1000 mg).
• Do not confuse this with codes for other chemotherapy agents or for the administration service itself.
• Ensure the medical record supports the drug, dosage, and medical necessity for its use.
