Before: SAWYER, P.J., and SAAD and BANDSTRA, JJ.
SAAD, J.
In this wrongful death action, defendants William F. Patton, M.D., and Pulmonary Medicine, P.C., appeal by leave granted from the trial court's order that denied their motion for leave to file notice of nonparty fault. We reverse and remand for further proceedings consistent with this opinion.

I. Procedural History
Plaintiff filed this wrongful death, medical malpractice action against defendants for their failure to timely diagnose and treat plaintiff's decedent, Jill I. Salter. In April 2002, plaintiff settled claims against defendants Chelsea Community Hospital; Chelsea Internal Medicine Consultants, P.C.; David K. Vallance, M.D.; and Yun Ching Chen, M.D., for $650,000. Thereafter, the settling defendants were dismissed from the case. On April 8, 2002, defendants Patton and Pulmonary Medicine, P.C., moved for leave to file notice of identification of Chelsea Community Hospital, Chelsea Internal Medicine Consultants, P.C.; David K. Vallance, M.D.; and Yun Ching Chen, M.D., as nonparties at fault pursuant to MCR 2.112(K). In response, plaintiff argued that liability is joint and several in medical malpractice cases under MCL 600.6304(6)(a) and that *539 defendants may not allocate fault to former defendants who settled their claims.
The trial court denied defendants' motion in a written opinion and order issued on August 6, 2002. Though the trial court ruled that an allocation of fault is proper under MCR 2.112(K), the court concluded that defendants' motion was untimely and that granting the motion would result in "unfair prejudice to the opposing party."

II. Analysis

A. Standards of Review
The interpretation and application of statutes are issues of law reviewed de novo on appeal. Danse Corp. v. Madison Hts., 466 Mich. 175, 178, 644 N.W.2d 721 (2002). Similarly, the interpretation of court rules constitutes a legal question that this Court reviews de novo. CAM Constr. v. Lake Edgewood Condo. Ass'n, 465 Mich. 549, 553, 640 N.W.2d 256 (2002).

B. Allocation of Fault
While the parties acknowledge that joint and several liability remains in medical malpractice cases like this one, where plaintiff was not at fault, defendants assert that the allocation of fault provisions in MCL 600.2957 and MCL 600.6304 nonetheless apply. See MCL 600.6304(6); Kokx v. Bylenga, 241 Mich.App. 655, 662 n. 3, 617 N.W.2d 368 (2000). A plain reading of MCL 600.6304 requires an initial allocation of fault, regardless of whether joint and several liability ultimately applies. MCL 600.6304 provides:
(1) In an action based on tort or another legal theory seeking damages for personal injury, property damage, or wrongful death involving fault of more than 1 person, including third-party defendants and nonparties, the court, unless otherwise agreed by all parties to the action, shall instruct the jury to answer special interrogatories or, if there is no jury, shall make findings indicating both of the following:
(a) The total amount of each plaintiff's damages.
(b) The percentage of the total fault of all persons that contributed to the death or injury, including each plaintiff and each person released from liability under section 2925d, regardless of whether the person was or could have been named as a party to the action.
(2) In determining the percentages of fault under subsection (1)(b), the trier of fact shall consider both the nature of the conduct of each person at fault and the extent of the causal relation between the conduct and the damages claimed.

* * *
(4) Liability in an action to which this section applies is several only and not joint. Except as otherwise provided in subsection (6), a person shall not be required to pay damages in an amount greater than his or her percentage of fault as found under subsection (1). This subsection and section 2956 do not apply to a defendant that is jointly and severally liable under section 6312.
Reading subsections 6304(1) and (2) with subsection 6304(6), the jury must first allocate fault under subsections 6304(1) and (2) and, in a medical malpractice case, if the plaintiff is without fault, liability is joint and several:
(6) If an action includes a medical malpractice claim against a person or entity described in section 5838a(1), 1 of the following applies:
(a) If the plaintiff is determined to be without fault under subsections (1) and (2), the liability of each defendant is joint and several, whether or not the defendant is a person or entity described in section 5838a(1).
*540 (b) If the plaintiff is determined to have fault under subsections (1) and (2), upon motion made not later than 6 months after a final judgment is entered, the court shall determine whether all or part of a party's share of the obligation is uncollectible from that party, and shall reallocate any uncollectible amount among the other parties, whether or not another party is a person or entity described in section 5838a(1), according to their respective percentages of fault as determined under subsection (1). A party is not required to pay a percentage of any uncollectible amount that exceeds that party's percentage of fault as determined under subsection (1). The party whose liability is reallocated continues to be subject to contribution and to any continuing liability to the plaintiff on the judgment.
Accordingly, notwithstanding the statute's retention of joint and several liability in medical malpractice actions where a plaintiff is not at fault, MCL 600.6304(6) explicitly requires an allocation of fault under subsections 6304(1) and (2). Further, the medical malpractice subsection, subsection 6304(6), refers the reader to subsections 6304(1) and (2) and subsection 6304(1) states that the jury or fact-finder shall allocate fault. "The word `shall' is unambiguous and is used to denote mandatory, rather than discretionary, action." STC, Inc. v. Dep't of Treasury, 257 Mich.App. 528, 537, 669 N.W.2d 594 (2003). The allocation of fault is not limited to situations where a plaintiff was at fault; subsections 6304(1) and (2) plainly require a comprehensive allocation of fault.[1]
This interpretation is consistent with the allocation of fault provision found in MCL 600.2957, which is to be read in pari materia with MCL 600.6304, State Treasurer v. Schuster, 456 Mich. 408, 417, 572 N.W.2d 628 (1998), and which provides in relevant part as follows:
(1) In an action based on tort or another legal theory seeking damages for personal injury, property damage, or wrongful death, the liability of each person shall be allocated under this section by the trier of fact and, subject to section 6304, in direct proportion to the person's percentage of fault. In assessing percentages of fault under this subsection, the trier of fact shall consider the fault of each person, regardless of whether the person is, or could have been, named as a party to the action.

* * *
(3) ... Assessments of percentages of fault for nonparties are used only to accurately determine the fault of named parties. If fault is assessed against a *541 nonparty, a finding of fault does not subject the nonparty to liability in that action and shall not be introduced as evidence of liability in another action.
Pursuant to subsection 2957(1), in wrongful death actions, it is mandatory for the trier of fact to allocate the liability of each person. Again, the word "shall" designates a mandatory provision. Roberts v. Mecosta Co. Gen. Hosp., 466 Mich. 57, 65, 642 N.W.2d 663 (2002). After mandating an allocation of liability to each person, subsection 2957(1) provides that the allocation of liability is to be "subject to section 6304, in direct proportion to the person's percentage of fault." This language indicates that the limitations set forth in MCL 600.6304(4) and (6) that prohibit allocating fault "in direct proportion to the person's percentage of fault" in medical malpractice cases where liability is joint and several take precedence over the procedure for allocating liability set forth in MCL 600.2957(1). Thus, to avoid rendering any of the language of MCL 600.6304(1), (4), and (6)(a) as well as MCL 600.2957(1) nugatory, we construe those provisions to provide that the fact-finder shall allocate liability among nonparties even in medical malpractice cases where the plaintiff is not at fault before joint and several liability is imposed on each defendant. Further, once joint and several liability is determined to apply, joint and several liability prohibits the limitation of damages to one's percentage of fault. While plaintiff urges us to conclude that allocation of fault to settling nonparties does not apply in medical malpractice cases where joint and several liability is imposed, "a court's constitutional obligation is to interpret, not rewrite, the law." Ambs v. Kalamazoo Co. Rd. Comm., 255 Mich.App. 637, 650, 662 N.W.2d 424 (2003). Any responsibility to rewrite the statutes lies with the Legislature.[2]

C. Setoff
Again, subsection 6304(4) makes clear that, regardless of whether a nonsettling defendant is only partially at fault, his liability is joint and several. Therefore, regardless of whether allocation of fault is used, a liable defendant is not entitled to a reduction of damages on the basis of that finding. Moreover, and contrary to defendants' argument below, the parties agreed at oral argument that allocation of fault has nothing to do with the nonsettling defendants' ability to recover from other, settling defendants. In Markley v. Oak Health Care Investors of Coldwater, Inc., 255 Mich.App. 245, 256-257, 660 N.W.2d 344 (2003), the Court held that common-law rules of setoff survived tort reform. Thus, plaintiffs are not entitled to double recovery from settling and nonsettling defendants because the judgment will be reduced by the amount of the settlement. Setoff, not contribution, applies and, therefore, the amount of the settlement and the entire judgment are at issue, not the amount of fault allocated to each settling and nonsettling defendant.

D. Timeliness of Motion
Though the trial court ruled that an allocation of fault is required, it denied defendants' motion to file notice of nonparty *542 fault because plaintiff would be prejudiced by the granting of the motion so late in the proceedings. MCR 2.112(K)(3)(c) provides:
The notice must be filed within 91 days after the party files its first responsive pleading. On motion, the court shall allow a later filing of the notice on a showing that the facts on which the notice is based were not and could not with reasonable diligence have been known to the moving party earlier, provided that the late filing of the notice does not result in unfair prejudice to the opposing party.
Defendants were undoubtedly late in filing the motion because they did so well over ninety-one days from the time they filed their first responsive pleading. However, as defendants point out, all the parties named in their notice were parties to the action up to the time they settled, and discovery was comprehensive. Furthermore, after the settlement, defendants almost immediately filed their motion to file notice of nonparty fault. Indeed, the court rule requires the trial court to grant the motion in this case because defendants could not have known about the need to file notice until after the settlement ("the court shall allow a later filing of the notice on a showing that the facts on which the notice is based were not and could not with reasonable diligence have been known to the moving party earlier....").
However, the second half of the rule requires that the plaintiff cannot suffer unfair prejudice by the grant of a late motion. In Staff v. Johnson, 242 Mich.App. 521, 532, 619 N.W.2d 57 (2000), this Court ruled that "orderly docket management" is a valid consideration and courts should not be required to "add additional parties without regard to the stage of the court proceedings and expiration of the two-year period of limitation." Staff is clearly distinguishable because, here, there is no statute of limitations problem, defendants clearly could not have filed the notice any sooner, and the named parties were all involved in the case during discovery. Thus, there is no prejudicial "change of focus" of the trial and, other than the fact that trial may have been delayed to give plaintiff more time to prepare, there does not appear to be a prejudicial effect on plaintiff. Indeed, as defendants note, it appears that the trial court decided the motion several weeks after it was filed and at least contributed to the need to adjourn the trial.
Under these facts, we hold that the trial court erred by failing to grant defendants' motion to file notice of nonparty fault. The allocation of fault is required by the statute and defendants filed the motion after the settlement.
Reversed and remanded for further proceedings consistent with this opinion. We do not retain jurisdiction.
NOTES
[1]  One could arguably interpret subsection 6304(4) to preclude allocation of fault in medical malpractice cases where joint and several liability exists because subsection 6304(4) provides that "[1]iability in an action to which this section applies is several only and not joint" and states that a person is not prevented from paying more damages than the percentage of the person's fault where subsection 6304(6) imposes joint and several liability. See, for example, Markley v. Oak Health Care Investors of Coldwater, Inc., 255 Mich.App. 245, 253-254, 660 N.W.2d 344 (2003).

In construing a statute, the court should presume that every word has some meaning and should avoid any construction that would render any part of a statute surplusage or nugatory. Hoste v. Shanty Creek Mgt., Inc., 459 Mich. 561, 574, 592 N.W.2d 360 (1999). As far as possible, effect should be given to every sentence, phrase, clause, and word. Pohutski v. City of Allen Park, 465 Mich. 675, 684, 641 N.W.2d 219 (2002).
Here, the only way to avoid rendering the statutory language at issue nugatory is to conclude that the statute requires an initial allocation of fault, but that, once joint and several liability is determined to apply pursuant to subsection 6304(6)(a), the imposition of joint and several liability prohibits limiting one's damages in proportion to that person's percentage of fault.
[2]  Though plaintiff cites several cases in support of the rule that under the law of joint and several liability "a remaining defendant may not allocate fault to any of the settling defendants," see Dep't of Transportation v. Thrasher, 446 Mich. 61, 82-83, 521 N.W.2d 214 (1994), Gagnon v. Dresser Industries Corp., 130 Mich.App. 452, 460, 344 N.W.2d 582 (1983), and Anderson v. Harry's Army Surplus, Inc., 117 Mich.App. 601, 613, 324 N.W.2d 96 (1982), each of those cases was decided before tort reform, and therefore before the enactment of the allocation of fault provisions found in MCL 600.6304 and MCL 600.2957 at issue here. Accordingly, this case law is not persuasive.
