Policy Notes

Idaho Medicaid eliminated 'behavior modification and consultation' from its managed care program, replacing it with Children’s Habilitation Intervention Services (CHIS) effective Dec. 1, 2025. ABA-like therapy is still covered under CHIS. The new system requires HCPCS codes instead of CPT codes and does not allow concurrent billing. Only one professional's services can be reimbursed per session.
