Notice for 340B pharmacy providers

The Centers for Medicare and Medicaid Services (CMS) requires the Mississippi Division of Medicaid (DOM) to define its policies and oversight activities related to 340B purchased drugs as outlined in CMS state release No. 161, dated Oct. 26, 2012.

In February 2017, letters were mailed to all Medicaid providers identified as 340B covered entities. These letters contained the 340B Covered Entity Initial Attestation Enrollment Form and billing policy guidelines.

The form completion and submission deadline was extended for 340B Covered Entities from March 1, 2017 to May 1, 2017. Based upon provider feedback, the effective date for 340B billing policy implementation was extended from April 1, 2017 to July 1, 2017.

DOM encourages stakeholder feedback regarding 340B requirements and billing policy guidelines. In an effort to ensure clear and consistent communication regarding 340B attestation and billing policy, DOM will be posting a 340B Question and Answers document online at and hosting an informational conference call.

Please submit your comments and questions for inclusion in the 340B Q&A document to, by Monday, June 5, 2017.
