My Twiist kit costs $582 a month and I pay $60 copay insurance. My supplemental coverage (UHC Empire plan) pays for the Twiist stuff entirely. I would not have tried it had it not been approved for coverage. I have been using it since 10/25 and have had some problems….highs that wouldn’t go down and a few lows…..some while sleeping (43) which i slept thru and lived. I would not have tried it had I not had an iPhone and already using a Libre 3 plus CGM. My overall blood sugar has been much lower overall….up to 70% in target range. My CMI (like A1C) has been 7.3 as opposed to pushing 10.0 before pump. I still am on my own as I have never talked to endo since pump except when he called me to go over my settings when appt canceled due to weather. No appt. known since then. Have a manual and was “trained” quickly by the Twiist rep who pronounced me “sufficiently trained” and told me to contact Twiist customer service. I have and have been on phone an hour or more each time working out problems. The Twiist reps have been very helpful and patient with their time. They even referred me to an Abbott Libre person when my CGM kept reading over 400 when my BG should have been coming down per Twiist. Anyways, overall improvement with pump.
