Knowing which fee codes are available within your specialty is an important aspect of billing correctly.
If you’re an anesthesiologist then submitting claims can be a bit more complicated than other specialties since fee codes don’t always have a set price, as they differ depending on time units or your patient’s BMI.
Thus, it’s really important to make sure you calculate time units correctly in order to avoid rejections.
