$37.76 Million CVS Insulin Pen Case Settled
Last month we wrote an article entitled: Guidelines for Dispensing Insulin Pens in their Original Carton. A few days later, the Office of Inspector General (OIG) announced that CVS had agreed to a $37.76 million settlement for violations of the False Claims Act by over-dispensing insulin pens between 2010 and 2020. Investigators found that Medicare, Medicaid, TRICARE, and the Federal Employees Health Benefits Program made significant overpayments for these prescriptions.
The overpayments stemmed from CVS pharmacies submitting incorrect days’ supply information, which allowed claims to be refilled earlier than appropriate. Updated package instructions promote dispensing insulin pens in their original carton, whereby the amount of insulin in a full box often exceeds plan limits. CVS pharmacies billed inaccurate days’ supplies and then refilled prescriptions before meeting the appropriate utilization threshold.
PAAS National® first notified members via email alert in January 2019, followed by a Newsline article in March 2019 titled, Breaking Insulin Boxes—Your Questions Answered, after the OIG announced a $269.2 million civil healthcare fraud settlement with Walgreens. The primary issue in this settlement involved the overpayments of insulin pens.
Automatic refill programs were a major contributor to this over-dispensing. Many patients received insulin far earlier than needed because pharmacies utilized the submitted days’ supply rather than the actual days’ supply. Since third-party payors can only reject early refills when an accurate days’ supply is reported, their ability to prevent inappropriate refills was “limited”.
Do not let your pharmacy fall into this same situation. Stay vigilant by ensuring your staff is trained to bill correctly when the smallest package size exceeds a plan limit. Utilize the automatic refill programs appropriately and safeguard your claims from audit recoupment and further scrutiny.
