Yes, Round Down
by: David

Yes, absolutely. You always round down when there is a fraction when you are figuring Days Supply.

Why? Because you always want to tell the patients' insurance company the exact amount of time the prescription will last (based on the quantity and the directions) but not longer.

In this example, with the medicine for pain, the sig/directions are:

"1-2 tablets po every 4-6 hours for pain." #20 pills

We figure the maximum amount of tablets that can be taken in one day and divide that into the quantity.

So, the maximum is 2 tablets every 4 hours. There are 6-four hour segments in 24 hours. Therefore, we multiply 2 tablets times 6 and come up with 12 tablets max in one day.

So now, we have 20 tablets. We divide 12 into 20 and come up with 1.6666 and because the remaining 8 tablets (20-12=8) will not last the patient another full day given at the maximum possible amount (based on the directions and the quantity left), we would then round down.

The reason we round down, for example, is due to the fact that if the doctor writes another prescription for the patient, for the same drug and same directions, but for a higher quantity, the insurance company already has the first prescription on record. Usually the first prescription needs to be used up at least 3/4 of the way before a new prescription or refill will be able to be run thru the insurance.

If the days supply is not calculated correctly it could delay the filling of the next prescription.

This will cause problems.

The customer may be frustrated, because they need their medicine and may have run out.

This can lead to negative health outcomes and a delay of treating the medical problem / illness / issue.
