STVX-packaged codes” (SI “Q1”) are packaged if they are billed on the same date of service with any other code with an SI of “S,” “T,” “V,” or “X.” If not, they are separately payable under a separate APC. “T-packaged codes” (SI “Q2”) are packaged only if they are billed on the same date of service with any other codes with an SI of “T.” If not, they are separately payable under a separate APC. Codes subject to payment as part of a composite (SI “Q3”) are packaged into the composite rate when all criteria for that composite are met. Otherwise, the services with SI “Q3” may be separately payable if otherwise assigned to a separate APC or packaged into other services, if not.
If more than one “STVX-packaged” (“Q1”) or “T-packaged” (“Q2”) code is reported without a separately payable service into which it would otherwise be packaged, separate payment is made only for the highest paying among them, and all others are packaged into that code. If any SI “Q1” or “Q2” codes are reported on the same day as any code that is subject to composite payment (“Q3”), and payment criteria are met for composite payment, the “Q1” and ”Q2” codes will be packaged into the composite payment.
The Q3 has to do with packaged services and payment, therefore yes you will still need the 25 modifier.
