Summary
Maryland Medicaid is transitioning to NCPDP Telecommunication Standard Version F6 for pharmacy transactions, with a phased implementation beginning August 14, 2027 (concurrent with Version D.0) and mandatory exclusive use by April 14, 2028. For 340B drug program claims, the identifier code is changing from Submission Clarification Code 20 (field 420-DK) to Submission Type Code AA (field D17-K8). Billing teams must update systems, coordinate with vendors, and prepare for impacts across claims processing, eligibility, and rebate reporting.
Action Required
REQUIREMENTS:
By August 14, 2027: Billing team and IT must transition pharmacy billing systems to support NCPDP Telecommunication Standard Version F6 alongside Version D.0 during the concurrent phase. Coordinate with pharmacy benefit managers, claims processing vendors (specifically Conduent for Maryland Medicaid Point-of-Sale), and information technology teams to ensure dual-version capability. Test both standards in pre-production environments with MDH and Conduent.
By April 14, 2028: Billing team and IT must ensure NCPDP Version F6 becomes the exclusive standard for all retail pharmacy transactions. Version D.0 will no longer be HIPAA-supported after this date. All 340B claims must use the new Submission Type Code AA (field D17-K8) instead of the legacy Submission Clarification Code 20 (field 420-DK). Update all claim submission rules and validation logic in billing software.
Immediately (before August 2027): Begin evaluating operational and system impacts. Identify changes needed in pharmacy claims processing, encounter reporting, eligibility inquiries, coordination of benefits, and rebate reporting workflows. Document current Version D.0 dependencies and create remediation plans. Establish communication with all business partners regarding timeline and requirements. Claims submitted after April 14, 2028 using outdated standards will be rejected or denied.
WHO: Billing team, IT department, compliance officer, pharmacy benefit manager liaison
WHERE: Billing software systems, claims submission modules, encounter reporting interfaces, eligibility systems, rebate processing systems
CONSEQUENCES: Non-compliance after April 14, 2028 will result in claim denials, operational disruptions, federal compliance violations, and inability to process 340B claims.
