Poor billing practices do not have to make a large number of patients leave to create meaningful revenue risk.

How this calculator works: We do not assume all patients are exposed to billing risk. We first narrow the population to patients who receive a statement or have patient responsibility. From there, national research suggests about 1 in 5 people recently received a medical bill they disagreed with or could not afford. Separately, 56% of patients say poor billing could make them likely to switch providers. Because stated intent does not fully translate into action, we apply a conservative behavioral discount and assume only 5% to 15% of stated switchers actually leave. In the base case, this puts roughly 0.45% of annual patient relationships at risk — about 4 to 5 patients per 1,000. The revenue impact is calculated using your own annual NPR per unique patient.
