No, try the section on the sacrament of Holy Orders, specifically the subsection (5): “The Dispenser of the Sacrament of Order”. Where you will find "Every validly consecrated bishop, including heretical, schismatic, simonistic, or excommunicated bishops can validly dispense the Sacrament of Order, provided he has the requisite intention, and follows the essential external rite (senta. certa). It is for this reason that the RCC considers the Orthodox, the Old Catholics (where this is still appropriate) and the PNCC to possess valid, if illicit, orders.So one would have to know about the Lutherans in question than merely that they were schismatic, excommunicated, or such.

I got it. Thank you. It is on page 457 on my version.
It makes reference to Dezinger:
855 [DS 1612] Can. 12. If anyone shall say that a minister who is in mortal sin, although he observes all the essentials which pertain to the performance or conferring of the sacrament, neither performs nor confers the sacrament: let him be anathema.
860 [DS 1617] Can. 4. If anyone shall say that the baptism, which is also given by heretics in the name of the Father and of the Son and of the Holy Spirit, with the intention of doing what the Church does, is not true baptism: let him be anathema.
Reading from Ott’s references in this section, it leads me to the Summa Theologica - Supplementum Q. 38, Art. 2
WHETHER HERETICS AND THOSE WHO ARE CUT OFF FROM THE CHURCH CAN CONFER ORDERS?
Wherefore others said that even those who are cut off from the Church can confer Orders and the other sacraments, provided they observe the due form and intention, both as to the first effect, which is the conferring of the sacrament, and as to the ultimate effect, which is the conferring of grace. But this again is inadmissible, since by the very fact that a person communicates in the sacraments with a heretic who is cut off from the Church, he sins, and thus approaches the sacrament insincerely and cannot obtain grace, except perhaps in Baptism in a case of necessity.
Hence others say that they confer the sacraments validly, but do not confer grace with them, not that the sacraments are lacking in efficacy, but on account of the sins of those who receive the sacraments from such persons despite the prohibition of the Church. This is the third and the true opinion. [Emphasis mine] (This is right before the Replies to the Objections).
What I believe is being said here is that, those who have been conferred the sacrament by validly ordained Bishops, who are separated from the Church, do not need to be re-consecrated when they enter in communion with the Church again. In as they remain in sin against the Church they do not confer the necessary grace because of this state of sin.
Hmmm, very interesting. I need to read more.
