Tips
- Long cases. Ablations can run several hours. Make sure your record shows handoffs and the full time.
- Lines. Arterial lines are common. Bill them separately when placed. See line billing.
- Physical status. These patients usually have significant heart disease. Capture P3 or P4 where it applies.
- Different staff, different paperwork. Make sure the lab's case list is reconciled with what you bill.
