Important: Modifier usage depends on documentation and payer policy. Never add a modifier without supporting documentation. Always verify payer-specific rules, as modifier policies vary. The information on this page is for educational purposes only and does not guarantee payment. When in doubt, consult the official CPT guidelines, NCCI Policy Manual, and payer-specific policies.
