Why does there even need to be a bill (in the sense of keeping track of costs on a per-patient basis) to begin with?
There doesn’t need to be a bill that the patient sees or has access to, but the costs need to be tracked so that governments can adequately budget for healthcare. Governments need to be able to make educated assumptions about future costs so that they can align their tax schedules to ensure that the monies are there to pay for the costs involved in healthcare. Individualising the costs per-patient and per-issue assists with forecasting costs when governments also have access to good data about prevalence. It also assists with ensuring that the correct number of specialists are available for a given issue.
