340B Medicare Advantage Underpayments

ALERT: Government Data Services LLC ("GDS") is helping providers by quantifying the exact amounts that each Medicare Advantage payor underpaid for 340B drugs from 2018 - 2022. Our deliverables include an executive summary by provider, by payor. Deliverables also include claims-level, line-item detail reports to support negotiations and/or litigation with Medicare Advantage payors in an effort to recover these underpayments. 

Government Data Services has extensive experience with large data sets including claims data and has created MAC-approved and audit-tested supporting documentation for over 2,300 providers for thousands of cost reports, appeals, litigation, and billing projects for issues including but not limited to Medicare DSH, Medicare Bad Debt, Uncompensated Care, Med Ed Shadow-billing, and similar CMS requirements.
