Coding for Paravertebral Blocks

Question:

What are the codes 64461-64463 used for?

Answer:

These codes are used to treat acute and chronic pain which includes thoracic pain after mastectomy or multiple rib fractures.  The block (paravertebral or paraspinous) targets the intercostal and spinal nerves and branches.  CPT 64461 is used for a single injection and 64462 is the add-on code for the second and any additional injection site.  Code 64463 is used for continuous infusion by catheter.  Imaging guidance is included and CPT code 64462 can only be reported once per day.
