Do any of you bill CPT 36500 selective venous catheterization during parathyroidectomy, for venipuncture for diagnostic sampling of parathyroid hormone to manage calcium levels perioperatively?

We have told our docs their documentation does not support catheterization, so we do not bill this CPT. Documentation is describing venipuncture (no catheter placed), which is not payable under the physician fee schedule.

They argue their associations instruct them to bill this code.

We are wondering if the rest of you have experience with this and what information you might offer.

Thank you in advance!
