Knee coders please help!

Hello fellow coders,

Could someone please help me with this surgery?

The doctor had 29873 (arthroscopic lateral release) and 27422 (open medial patella femoral ligament reconstruction. Also a autograft hamstring harvest requiring separate incision and additional 15 minutes.

27422-22 was what was coded (22 for separate hamstring incision)

The doc feels that both procedures should be billed. I told him the 29873 is bundled into the 27422. Opinions? Or help me explain why?

Thanks in advance!

Heather
