The CPT® Code 64484 refers to the procedure of administering injection(s) of anesthetic agent(s) and/or steroids via a transforaminal epidural approach, specifically with the aid of imaging guidance such as fluoroscopy or computed tomography (CT). This procedure is performed at the lumbar or sacral regions of the spine and is designated as an additional level injection, meaning it is billed separately in conjunction with a primary procedure. The transforaminal epidural injection is a targeted method that allows for precise delivery of medication around a specific nerve root, which is crucial for alleviating pain and inflammation associated with various spinal conditions. The foramina are small openings located between the vertebrae through which nerve roots exit the spinal canal, making them ideal sites for intervention. The process begins with the cleansing and preparation of the skin over the affected vertebra, followed by the careful advancement of a needle into the foramen under imaging guidance. This technique may involve the use of radiopaque contrast material to ensure accurate needle placement, enhancing the visibility of the procedure. Once the needle is correctly positioned, the anesthetic and/or steroid is injected around the nerve root to provide therapeutic relief. It is important to note that CPT® Code 64484 is utilized for each additional level injected beyond the primary procedure, which is coded separately under CPT® Code 64483.

The transforaminal epidural injection procedure, represented by CPT® Code 64484, is indicated for various conditions that involve nerve root irritation or inflammation. These indications may include:
The transforaminal epidural injection procedure involves several key steps to ensure accurate delivery of the anesthetic and/or steroid medication. The steps are as follows:
After the transforaminal epidural injection, patients are typically monitored for a short period to assess for any immediate adverse reactions. It is common for patients to experience some relief from pain shortly after the procedure, although the full effect of the medication may take several days to manifest. Patients are usually advised to avoid strenuous activities for a specified period and may be given instructions on pain management and follow-up care. Additionally, any specific post-procedure care instructions provided by the physician should be followed to ensure optimal recovery and effectiveness of the treatment.
