Insurance is denying 22214 and 22216 stating that "This was denied because the procedure is not eligible for reimbursement with the reported diagnosis." Also denied was 22614 stating it is part of another service. Any know if this denial is true and if there is a diagnosis code that should be used for 22214 and 22216

Was stage one done on a different date or in the same operative session? I didn't add any codes below for that part.

Without seeing the body of the op note to confirm everything, the 22614 is correct for the L3-L4 because according to that header snip, there was no interbody at that level, correct?

Insurance is correct. You have no deformity diagnosis for 22214 or 22216. I would have to see the op note, but there were no other diagnoses? Deformity must be the primary diagnosis. Not for a slight degenerative curve in the context of severe stenosis. I have never seen it called "releasing" osteotomy. Would have to see the actual description. Usually they call out SPO.

You seem to be missing possible 22848 (unless it bundles, been a while since I coded spine) and possible 20939 depending on payer and op note body description. 22634 should be x2, 22853 should be x3, 27280 should have mod 50.
If the osteotomies were not for deformity, it may open the possibility for using 63052/63053 depending on op note body if for decompression. 20936 & 20930 usually are considered inclusive and aren't reported separately depending on payer.

Reporting also depends on if your group wants all codes reported for RVU capture but then adjusts them for billing the claim, or if you code to the payer when entering. I have seen where a coder has to list out every single code, even if bundled or not reportable just for code capture, but then the coding is adjusted for the payer/actual claim.
