Hi, out office is debating on when to bill a malignant plerual effusion. The report says a pt has cancer. The report also states the pt has plerual effusion. It does not reference it to the cancer. One coder wants to bill the effusion as malignant because the pt has cancer. Others don’t agree because it doesn’t say malignant effusion. Can anyone advise us on the correct effusion code. Thanks so much.
