Are you able to bill an E/M 99xxx code with a 92xxx with same date of service? for instance, assume a patient had scheduled a routine eye exam, but foreign body discovered that day, billed medically and rescheduled for following week. The following week an E/M done and the patient healthy enough to go through with refractive exam. How do you bill for this? Can you bill medically and also under routine vision? Could you bill 99213 and 92015? Or even 99213 and 92004?
