Summary
Effective 01/01/2027, Ambetter from Magnolia Health will discontinue coverage for 45 HCPCS H codes (behavioral health and substance abuse treatment services) while adding coverage for H0006. Billing teams must immediately identify affected services, update claim submission logic, and prepare providers for coverage gaps to avoid claim denials.
Action Required
By 12/31/2026: (1) Billing team must update billing system rules to deny or route for manual review all claims containing H0003, H0004, H0005, H0007-H0047, H1011, and H2001-H2033 for Ambetter from Magnolia Health members. (2) Create alert logic to flag these codes before submission. (3) Update claim templates and encounter forms to remove these non-covered codes or add warnings for providers. (4) Notify all behavioral health and substance abuse treatment providers of the coverage discontinuation and identify alternative billing codes or payers. (5) Audit outstanding claims submitted in December 2026 to ensure no codes are billed for 01/01/2027 service dates. (6) Confirm H0006 is active and billable in system starting 01/01/2027. Failure to update billing logic will result in systematic claim denials and payment delays.
