Summary
KMAP (Kansas Medicaid) now requires specific anesthesia modifiers (AA, QK, QX, QY, QZ) for all anesthesia codes 00100-01999 except 01990 and 01996. Teaching anesthesiology claims must use AA modifier first, followed by GC modifier, and certain modifiers (QK, QX, QY) are reimbursed at only 50%.
Action Required
Immediately: Billing team must update system to require one of these modifiers (AA, QK, QX, QY, QZ) for all anesthesia codes 00100-01999 except 01990 and 01996 for Kansas Medicaid claims. For teaching cases, configure system to require AA modifier first followed by GC modifier. Update fee schedules to reflect 50% reimbursement for QK, QX, and QY modifiers. Claims without required modifiers will be denied.
