OPINION
In this interlocutory appeal of an order denying a motion to dismiss, the appellant *837health care provider contends that the trial court was required to dismiss the claims against it because the claimant failed to serve the provider with expert reports within 120 days after filing an original petition against a different defendant in separate suit. We affirm.
I. Factual and Procedural Background
On June 16, 2008, Nicole Priester sued Anthony Ademolu in Harris County Civil Court at Law No. 4 for sexual assault and intentional infliction of emotional distress. The assault allegedly occurred while Pries-ter was a patient at West Houston Medical Center, where Ademolu was employed as a technician. Counsel for Priester and Ade-molu agreed on the record that Priester’s suit did not assert a health care liability claim and that Ademolu would not require Priester to comply with the procedures for such claims as set forth in Chapter 74 of the Civil Practices and Remedies Code.
On March 27, 2009, Priester filed a separate lawsuit in a Harris County district court against CHCA West Houston, L.P. d/b/a West Houston Medical Center (“CHCA”). Within 120 days after filing suit against CHCA in the district court, Priester served CHCA with three expert reports.1 CHCA moved to dismiss the claims against it, arguing that Priester was required to serve it with expert reports within 120 days after suing Ademolu in the county civil court at law. The district court denied the motion, and CHCA brought this interlocutory appeal.
II. Governing Law
Within 120 days of filing the original petition in a health care liability suit, the claimant must serve each party with one or more expert reports, together with the curriculum vitae of each expert listed in the report. Tex. Civ. Prac. & Rem.Code Ann. § 74.351(a) (Vernon Supp.2009).2 For each physician or health care provider against whom a health care liability claim is asserted, the report must provide a fair summary of the expert’s opinions as to the applicable standard of care; the manner in which the care provided failed to meet that standard; and the causal relationship between that failure and the injury, harm, or damages claimed. Id. § 74.351(r)(6). If the claimant fails to timely serve a defendant physician or health care provider with an expert report, the trial court must grant the defendant’s motion to dismiss the claim with prejudice. Id. § 74.351(b).
When reviewing a trial court’s ruling on such a motion to dismiss, we apply the abuse-of-discretion standard. Mokkala v. Mead, 178 S.W.3d 66, 70 (Tex.App.-Houston [14th Dist.] 2005, pet. denied). An abuse of discretion occurs when a trial court acts in an unreasonable and arbitrary manner, or when it acts without reference to any guiding principles. Id. We defer to the trial court’s factual determinations, but review questions of law de novo. Id. Thus, to the extent resolution of the issue before the trial court requires interpretation of the statute itself, we apply a de novo standard. Id.
*838To interpret a statute, we must ascertain and give effect to the legislature’s intent as expressed in the statute’s language. Presidio Indep. Sch. Dist. v. Scott, 309 S.W.3d 927, 929 (Tex.2010). In doing so, we use the definitions prescribed by the legislature and any technical or particular meaning the words have acquired. Tex. Gov’t Code Ann. § 311.011(b) (Vernon 2005). Otherwise, we apply the words’ plain and common meaning unless the legislature’s contrary intention is apparent from the context or such a construction would lead to absurd results. City of Rockwall v. Hughes, 246 S.W.3d 621, 625-26 (Tex.2008). We presume that the legislature intended a just and reasonable result. Tex. Gov’t Code Ann. § 311.021(3). Moreover, “in interpreting a statute, a court shall diligently attempt to ascertain legislative intent and shall consider at all times the old law, the evil, and the remedy.” Tex. Gov’t Code Ann. § 312.005. Thus, even when interpreting an unambiguous statute, we may consider the statute’s object, the circumstances of its enactment, legislative history, and former statutory provisions. Tex. Gov’t Code Ann. § 311.023.
III. Analysis
CHCA contends that the petition Pries-ter filed in her earlier suit against Ademo-lu contained health care liability claims, and thus, she was required to serve CHCA with expert reports within 120 days after suing Ademolu in the county civil court at law, even though CHCA was not a party to that action. CHCA’s argument is based in part on section 74.351(a), which provides as follows:
In a health care liability claim, a claimant shall, not later than the 120th day after the date the original petition was filed, serve on each party or the party’s attorney one or more expert reports, with a curriculum vitae of each expert listed in the report for each physician or health care provider against whom a liability claim is asserted. The date for serving the report may be extended by written agreement of the affected parties. Each defendant physician or health care provider whose conduct is implicated in a report must file and serve any objection to the sufficiency of the report not later than the 21st day after the date it was served, failing which all objections are waived.
Tex. Civ. PRAC. & Rem.Code Ann. § 74.351(a) (Vernon Supp.2009) (emphasis added). An earlier version of this section provided that expert reports were to be served “not later than the 120th day after the date the claim was filed.”3 Citing Methodist Charlton Medical Center v. Steele, CHCA argues that the legislature “clearly intended to make Chapter 74’s expert report requirements more stringent when it amended the statute in 2005.” See 274 S.W.3d 47 (Tex.App.-Dallas 2009, pet. denied).4 According *839to CHCA, this change required Priester to serve CHCA with an expert report within 120 days of suing Ademolu, even though CHCA was never a party to any litigation with Priester during that time.
We need not address the parties’ dispute as to whether Priester previously asserted a health care liability claim against Ademolu5 because even if she did, such allegations would not have triggered a duty that Priester serve CHCA with an expert report. The filing of an original petition does not “start the clock” for the claimant to serve expert reports on health care providers whom the claimant has never named as a party. The 2005 amendment to section 74.351(a) clarifies when an expert report must be served, not who must be served. See S. Comm, on State Affairs, Bill Analysis, Tex. H.B. 2645,79th Leg., R.S. (2005); H. Comm. On Civil Practices, Bill Analysis, Tex. H.B. 2645, 79th Leg., R.S. (2005).6 Both before and after the amendment, claimants were required under section 74.351(a) to serve expert reports “on each party or the party’s attorney.” Tex. Civ. Prac. & Rem.Code Ann. § 74.351(a) (emphasis added). Both before and after the amendment, expert reports have been required as to “each physician or health care provider against whom a liability claim is asserted.” Id. (emphasis added). Both before and after the amendment, the consequence for failure to timely serve parties with an expert report “as to a defendant physician or health care provider” has been that, on such a defendant’s motion, the trial court must enter an order that awards the defendant “reasonable attorney’s fees and costs of court” and “dismisses the claim with respect to the physician or health care provider, with prejudice to the refiling of the claim.” Id. § 74.351(b) (emphasis added). Thus, treating the filing of an “original petition” as triggering a duty to serve expert reports on nonparties would be inconsistent with the remainder of the statute.
In arguing that the trial court abused its discretion by failing to dismiss Priester’s claims against it, CHCA cites cases in which courts have held that a plaintiff in a health care liability suit cannot restart the *840statutory deadline to file an expert report by (a) nonsuiting and refiling the same claims against the same defendant,7 (b) amending the petition to assert the same claims against the same defendant8 or (c) amending the petition to add additional health care liability claims to those already asserted against a particular defendant.9 In each of these cases, however, courts in effect held that the statutory deadline to serve the parties to a suit with expert reports concerning a particular health care provider’s conduct is measured from the date that the plaintiff first made that provider a defendant in a health care liability lawsuit.
Such cases are readily distinguishable from the circumstances presented here. It is undisputed that Priester served CHCA with expert reports within 120 days after filing the original petition in this, her original lawsuit against CHCA, and CHCA cites no case in which a court has held that in amending section 74.351(a), the legislature intended to require a claimant to serve expert reports to a health care provider before the claimant has made the provider a party to any suit. To the contrary, even when a defendant health care provider has been added to a pending suit by amendment of the petition, courts consistently have held that expert reports as to the claims against that defendant must be filed within 120 days after an amended petition first added that provider to the case. See, e.g., Daybreak Cmty. Servs., Inc. v. Carbrite, 320 S.W.3d 865, 871-73 (Tex.App.-Amarillo 2010, no pet.); Hayes v. Carroll, 314 S.W.3d 494, 501 (Tex.App.Austin 2010, no pet.); Stroud v. Grubb, — S.W.3d -, -(Tex.App.-Houston [1st Dist.] 2010, pet. filed); Arizpe v. Wilcox, No. 04-09-00408-CV, 2010 WL 1708285, at *3 (Tex.App.-San Antonio Apr. 28, 2010, pet. filed) (mem.op.); Padre Behavioral Health Sys., LLC v. Chaney, 310 S.W.3d 78, 85 (Tex.App.-Corpus Christi 2010, no pet.); Osonma v. Smith, No. 04-08-00841-CV, 2009 WL 1900404, at *2 (Tex.App.-San Antonio July 1, 2009, pet. denied) (mem.op.). The reasoning of those cases apply here with even more force because the first pleading to assert claims against CHCA was also the original petition in the case.
We overrule the sole issue presented in this appeal and affirm the trial court’s ruling denying CHCA’s motion to dismiss.
