The value contains a string of binary digits; each digit of the value indicates which tiers are on the formulary.


The CCW constructs the Plan Characteristics File from information submitted by plan sponsors to CMS’s Health Plan Management System (HPMS).

For those plans that did not report, the value of this variable will be blank.
