Staged AVF Creations

Question:

The op note states patient is getting first stage of a two-stage brachiobasilic vein transposition AV fistula. On the first encounter/procedure would you bill 36819 even though the transposition has not occurred yet? Or 36821? I know on the second encounter (stage 2) I would bill 36832. I feel like with billing 36821 then later 36832 the provider never gets "credit" for doing the transposition.
