What is RxDC reporting?
Last updated October 2, 2026
RxDC (prescription drug data collection) reporting requires group health plans to submit detailed prescription drug and healthcare spending data to CMS annually by June 1 for the prior calendar year. Carriers and PBMs usually file most sections, but employers must supply plan-level data and confirm the filing.
RxDC reporting gives regulators a market-wide view of drug and healthcare costs. Every group health plan — fully-insured and self-funded — must ensure an annual submission to CMS covering premiums, enrollment, spending by category, and detailed prescription drug data, due June 1 for the previous calendar year.
In practice the filing is a relay race: carriers, TPAs, and pharmacy benefit managers submit most data files, while the employer supplies plan-level information (like premium splits between employer and members) and confirms its plan is included in the vendors' submissions.
The employer-side failure mode is assuming a vendor filed when it didn't, or missing the vendor's data-request deadline in the spring. Calendar the vendor requests, keep written confirmations of each year's submission, and note the completion in committee records.
