Two Stage ACL Treatment

Question:

Our docs have been seeing more patients that have had a re-tear of ACL and are wanting to do bone grafting of tunnels in addition to medial and lateral meniscectomies and removal of hardware and evaluate the ACL to see if it repairable. We are wondering if the bone grafting is separately billable and what code we should use for this?

Answer:

Thank you for your inquiry and recognizing we are not able to provide definitive coding advice without an operative note. This is a good question.

There is no specific CPT code for the first of two stage revision of an ACL. Current guidance for the removal of plugs, debridement of tunnels and filling the tunnels with a bone substitute is coded to 29999.
