M.G.L. c. 12C, § 16(a) requires that CHIA “consider the effect of drug rebates and other price concessions in the aggregate without disclosure of any product or manufacturer-specific rebate or price concession information, and without limiting or otherwise affecting the confidential or proprietary nature of any rebate or price” when detailing cost growth trends in its annual report.
As per regulation 957 CMR 2.00 (Payer Data Reporting) and the latest Administrative Bulletins, CHIA requires payers to submit a prescription drug rebate data file. This data will permit consideration of the effect of prescription drug rebates and other pharmaceutical manufacturer price concessions such as coverage gap discounts on aggregate cost growth trends
All prescription drug rebate data will be submitted by using a pre-formatted Excel template. Reports are required to be submitted through CHIA’s Web-Based Submission Platform which requires data submitter registration via a CHIA Data Reporter User Agreement.
The Prescription Drug Rebate Data Specification Manual provides additional technical details to assist payers in reporting and filing prescription drug rebate data.

New users must register to submit data via CHIA Submissions.
