Summary
Effective January 1, 2027, Ambetter of Oklahoma will discontinue coverage for 46 HCPCS H codes commonly used for behavioral health, substance abuse treatment, and related services. Simultaneously, H0006 coverage begins on the same date. The billing team must identify all affected claims and establish processes to deny or redirect these codes for Ambetter Oklahoma members.
Action Required
By December 15, 2026: Billing team must update billing software to flag and deny all claims containing the 46 non-covered H codes (H0003-H0047 and H1011, H2001-H2033, excluding H0006) when submitted to Ambetter of Oklahoma. Simultaneously configure the system to allow H0006 claims for Ambetter Oklahoma members starting 01/01/2027. Update claim scrubbing logic to reject these codes at submission. Notify behavioral health and substance abuse treatment providers of the coverage changes and provide alternative coding guidance if available. Failure to implement these changes will result in claim denials and potential accounts receivable impact. Contact Ambetter Provider Relations Representative for alternative billing code guidance.
