I agree with your coding if there "was" a complication. However if there is not a complication, then I would use the 385.83.
I disagree, a tube is a retained foreign body. I know the surgeon puts them there for a reason. If you check the cross coder (which I have included in this post) for diagnosis for removal of PE tubes, you will find the diagnosis 385.83

I dont think that CPT would have put that diagnosis in the cross coder if it did not apply.
