SBC Calculator Illustrations - SBCCovgCalc dynamic link library (DLL)

This template is designed to provide a mechanism by which health plans can obtain values for the three coverage examples on page 5 of the Summary of Benefits and Coverage (SBC) Coverage template provided by Centers for Medicare and Medicaid Services (CMS), by electronically sending the 140 parameter values required by the Excel-based SBC coverage example calculator to the DLL. This allows for an automated calculation of the benefit scenario costs detailed on page 5 of the SBC. Returned values can then be saved to a text file, database, or mail merge document, for further use.

This calculator matches the data and logic used in the April 2017 version of the CMS Excel-based coverage example calculator.
