Summary
IHCP will mass reprocess previously denied CRNA claims that were incorrectly rejected for modifier compatibility issues. All CRNA services must now include modifier QX (medically directed, 50% reimbursement) or QZ (not medically directed, 100% reimbursement) regardless of which NPI is used for billing.
Action Required
Immediately: Billing team must ensure all CRNA service claims include either modifier QX (for medically directed services at 50% reimbursement) or QZ (for non-medically directed services at 100% reimbursement). Update billing system rules to require these modifiers for all CRNA claims regardless of whether billing under CRNA's NPI or supervising physician's NPI. Monitor remittance advices starting Nov 26, 2025 for reprocessed claims with ICNs beginning with 52.
