september 10, 2025
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.
Payers must submit data annually in accordance with regulation 957 CMR 2.00 (Payer Data Reporting) and the latest Administrative Bulletins.
Pursuant to 957 CMR 2.00, 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. The Prescription Drug Rebate Data Specification Manual provides additional technical details to assist payers in reporting and filing prescription drug rebate data.
Prescription drug rebate files will contain different record types, including:
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.
Most data is submitted via one of CHIA’s Web-Based Submission Platforms. A CHIA Data Reporter User Agreement is required to access and use any of CHIA's submission platforms.
The CHIA Data Reporter User Agreement establishes the terms and conditions under which an organization and its authorized users may access CHIA's Web-Based Submission Platforms. The Agreement requires the following components: a) Main Agreement (Pages 1–4): Completed and signed once per Data Reporter entity b) Exhibit A – User Authorization Form: Completed and signed separately for each individual user who will access CHIA's platforms, including the Agreement Administrator.
