Facet joint aspiration

What is the CPT for percutaneous aspiration of the L3-L4 facet joint?
SuperCoder Answered Thu 28th of March, 2019 08:01:19 AM

Hello Amy,

Thank you for your question.


CPT® does not include a code for percutaneous aspiration of the L3-L4 facet joint. Therefore, you should report 64999 (Unlisted procedure, nervous system). If your provider uses fluoroscopic guidance during the procedure, report it with 77003 [Fluoroscopic guidance and localization of needle or catheter tip for spine or paraspinous diagnostic or therapeutic injection procedures (epidural or subarachnoid)].


Note: When reporting a procedure with an unlisted code, submit a cover letter explaining the reason for choosing the unlisted code instead of a defined, active code. Include one or more similar codes and compare your service to those codes to justify the claim amount you are billing. Also include the operative notes or other relevant documentation to strengthen the claim and to avoid a possible denial.



Please feel free to write if you have any question.
