Unfortunately, this is not possible when the dose is variable, as during titration or when patients count carbs.
True - but, as a pharmacist who actually has to submit audit reports, I have to document dosage. When you write "ud" - I ask the pt what the parameters are & I document it on the rx. Technically, I'm supposed to document with you, but that is time consuming for both of us.
Currently, there are very few insurance plans which will take "ud" directions on anything as a direction - so we're documenting on the rx what the pt is saying to document the days supply with the amount we dispense.
We know what is out of the norm - it can sometimes take 5-6 vials of Humalog to fill & prime a pump & allow for missteps at the beginning of a pump pt. But, after a pump pt is stabilized, it takes less.
Personally, I'd rather you write to use x-y units before meals & q2h prn BS > "qrs" up to 10 (or "n") times per day, with parameters high & low. That gives me the minimum required & the ability to titrate up to a higher amount per 30/90 days. I'll still use "inject as directed by doctor" on the label...but, for insurance - they'll see I've made the attempt to document the dose.
Strips are more controlled than insulin. Some plans allow for only 200 strips/month - no matter how many times they test. I have about 5 plans which will allow up to 300 strips/month. Beyond that...the pt buys the strips (or just doesn't test!). Rarely, I can get a prior auth for more strips & they, for the most part are pump pts.
For the OP - yes, give me an idea of the range the pt may use, which would influence the # of syringes, strips, insulin, etc... I'll document the amount so I can dispense the full box of 100 syringes rather than break it & dispense just 50-60.
Otherwise....when I'm audited, if I don't have a documented dose on the rx, the insurance company will charge back my company & rebill the pt. You don't want that - its cheaper to just buy the insulin & syringes OTC rather than have me dispense it in that case.
For the most part - the use of "take as directed" on anything does not fly for insurance. We may write it on the label, but we'll document what you told the pt & if the pt is confused or someone brings the rx in on their behalf, we'll have to bother your office staff. We don't like to do that.
