v.
The ESTATE OF Vicente TAVAREZ, Jr., Deceased, Appellee.
No. 13-01-841-CV.
Court of Appeals of Texas, Corpus Christi-Edinburg.
July 31, 2003.
*283 William Kimball, Harlingen, for Appellant.
Chris Franz, Sweetman, Skaggs, Lawler & Franz, Edinburg, Marion R. Lawler III, Sweetman, Skaggs, Lawler & Franz, Brownsville, for Appellee.
Before Chief Justice VALDEZ and Justices RODRIGUEZ and AMIDEI.[1]

OPINION
Opinion by Justice RODRIGUEZ.
This is a medical malpractice action. Appellant, Mary Ann Barnes Pech, sued appellee, the Estate of Dr. Vicente Tavarez, Jr., deceased (the Estate), for malpractice arising from a surgery performed by Dr. Tavarez. The Estate moved for traditional summary judgment asserting Pech was barred by limitations under the *284 two-year statute on medical malpractice actions, and, alternately, under the open courts doctrine. The trial court granted the Estate's motion and dismissed the case. By three points, Pech contends the trial court erred in dismissing the suit in its entirety because: (1) issues of material fact remain regarding the Estate's limitations defense; (2) Joan Tavarez, as executrix or personal representative of the Estate, was not a moving party for summary judgment; and (3) the judgment was based on abandoned claims. We affirm.

I. Background
In April 1996, a mammogram revealed a lump in Pech's left breast. Pech was referred to Dr. Tavarez, a surgeon. A sonogram, ordered by Dr. Tavarez, confirmed the results of the mammogram. Prior to surgery, Pech was under the impression that Dr. Tavarez would do a non-radical biopsy, that the pathologist would examine the tissue, and that Dr. Tavarez would do semi-radical surgery only if the tissue were cancerous. Dr. Tavarez performed the surgery on May 20, 1996. When the bandages were removed during a follow-up visit on May 24, 1996, Pech was "shocked and horrified by the radical nature of the surgery." During the May 24 visit, Dr. Tavarez informed Pech he had removed the lump and it was benign. After several follow-up visits to Dr. Tavarez's office, Pech did not see the doctor again. Dr. Tavarez died thereafter.
On November 3, 1998, approximately two and one-half years after the surgery, Pech had a routine mammogram that was ordered by Dr. Andrew de la Garza. This mammogram again revealed a lump in her left breast. The lump was the same size and in approximately the same location as the lump Dr. Tavarez had reportedly removed in May 1996. Pech assumed that the lump was a new one. Pech testified at her deposition that some time before December 30, 1998, Dr. de la Garza told her it was the same lump. On April 23, 1999, Dr. Ramesh G. Shah biopsied the lump using a non-radical needle biopsy method, and on April 27, 1999, Dr. Shah informed Pech that the biopsied lump was not a new lump. It was Dr. Shah's opinion that it was not necessary to remove the biopsied lump because it was determined to be benign.
Because of personal matters, including her own health concerns and those of family and friends as well as the death of her father and the care of her mother, Pech did not begin inquiring into legal services until late October 1999. Pech filed suit alleging negligence against the Estate on March 13, 2000. On April 19, 2000, Pech amended her petition identifying the Estate and Joan Tavarez, executrix, or alternately, personal representative of the Estate, as defendants.
On June 22, 2001, the Estate filed its amended motion for summary judgment asserting a limitations defense based on (1) an absolute bar because Pech learned of her injury and the alleged malpractice within the two year limitations period, and (2) alternately, the open courts doctrine because Pech did not use diligence in filing her lawsuit. Pech filed her second amended petition on July 13, 2001, noting that "Mrs. Tavarez and the Estate have already made their general appearance in the case." In this amended petition, Pech alleged Dr. Tavarez was negligent in the following respects:
1. In failing to remove the lump from her left breast in 1996;
2. In failing to disclose to her the fact that he had not removed the lump even after performing the surgery; and
3. In telling her the lump was removed and was benign. *285 Absent from this amended petition was Pech's claim that Dr. Tavarez was negligent in performing a more radical surgical procedure than was required.
On August 24, 2001, the trial court granted the Estate's motion for summary judgment on the limitations defense and dismissed the entire case with prejudice. This appeal ensued.

II. Standard of Review
We must determine whether the summary judgment proof establishes as a matter of law that there is no genuine issue of material fact as to one or more of the essential elements of the plaintiff's cause of action or whether the defendant has conclusively established all elements of his affirmative defense. Velsicol Chem. Corp. v. Winograd, 956 S.W.2d 529, 530 (Tex. 1997); Walker v. Harris, 924 S.W.2d 375, 377 (Tex.1996); Crain v. Smith, 22 S.W.3d 58, 59 (Tex.App.-Corpus Christi 2000, no pet.); see City of Houston v. Clear Creek Basin Auth., 589 S.W.2d 671, 678 (Tex. 1979). When reviewing a summary judgment, we take as true all evidence favorable to the non-movant and indulge every reasonable inference in the non-movant's favor. See Cathey v. Booth, 900 S.W.2d 339, 341 (Tex.1995); Nixon v. Mr. Prop. Mgmt. Co., 690 S.W.2d 546, 549 (Tex.1985). The propriety of a summary judgment is a question of law; therefore, we review the trial court's granting of a motion for summary judgment de novo. Natividad v. Alexsis, Inc., 875 S.W.2d 695, 699 (Tex. 1994); Tex. Commerce Bank-Rio Grande Valley v. Correa, 28 S.W.3d 723, 726 (Tex. App.-Corpus Christi 2000, pet. denied).

III. Limitations Defense
By her first issue, Pech claims the trial court erred in issuing summary judgment against her on the basis of the Estate's limitations defense.

A. The Law
The discovery rule, which tolls the beginning of the statute of limitations in tort cases until the plaintiff has learned or should have learned of the incident that gave rise to his claim, does not apply under article 4590i of the Medical Liability Insurance Improvement Act. Tex.Rev.Civ. Stat. Ann. art. 4590i, § 10.01 (Vernon Supp 2003) (absolute bar); Jennings v. Burgess, 917 S.W.2d 790, 794 (Tex.1996). Therefore, because the present suit was filed almost four years after the surgery at issue in this case, this suit would be time-barred based on the two year statute of limitations. However, under the Texas Constitution's open courts provision, article 4590i may not operate as a complete bar to a claim that is otherwise assertable under common law. Tex. Const. art. I, § 13 (persons bringing common-law claims will not unreasonably or arbitrarily be denied access to courts); see Shah v. Moss, 67 S.W.3d 836, 842 (Tex.2001) (citing Neagle v. Nelson, 685 S.W.2d 11, 12 (Tex. 1985)).
A prima facie case under the open courts provision may be successfully established upon a showing that the litigant has a cognizable common-law cause of action, and the restriction of the claim is unreasonable or arbitrary when balanced against the statute's purpose. Shah, 67 S.W.3d at 842; Diaz v. Westphal, 941 S.W.2d 96, 100 (Tex.1997). Once a plaintiff establishes a prima facie violation, she must show she used due diligence in bringing the suit within a reasonable time after learning about the alleged wrong. Shah, 67 S.W.3d at 847; Nelson v. Krusen, 678 S.W.2d 918, 921-22 (Tex.1984); DeRuy v. Garza, 995 S.W.2d 748, 752 (Tex.App.-San Antonio 1999, no pet.). The reasonable time is given in order to allow a claimant to investigate, prepare and file suit after *286 discovering her injury. Gagnier v. Wichelhaus, 17 S.W.3d 739, 745 (Tex.App.-Houston [1st Dist.] 2000, pet. denied); see DeRuy, 995 S.W.2d at 752.
"In health care liability claims, there is no clear authority as to what is a `reasonable time' within which to file suit after discovering an injury outside the statute of limitations." Gagnier, 17 S.W.3d at 745. Whether a plaintiff has used the degree of diligence required is ordinarily a question of fact to be determined by the trier of fact; however, it may be "determined as a matter of law when the evidence, construed most favorably for the claimant, admits no other conclusion." DeRuy, 995 S.W.2d at 752-53 (quoting Neagle, 685 S.W.2d at 14 (Kilgarlin, J., concurring)). Compare Gagnier, 17 S.W.3d at 745 (holding ten months not per se unreasonable when defendants delayed in providing plaintiff with medical records, and plaintiff was recovering, consulting with an attorney, and investigating her claim), and DeRuy, 995 S.W.2d at 753 (Tex.App.-San Antonio 1999, no pet.) (holding slightly less than one year not per se unreasonable when plaintiff was recuperating for three months, consulted an attorney six months later, and filed suit three months later), with Shah, 67 S.W.3d at 847 (holding seventeen month delay was unreasonable as a matter of law when plaintiff offered no legitimate explanation accounting for delay), and Voegtlin v. Perryman, 977 S.W.2d 806, 813 (Tex.App.-Fort Worth 1998, no pet.) (delay of more than one year unreasonable when plaintiff offered no explanation for delay), and Fiore v. HCA Health Servs. of Tex., Inc., 915 S.W.2d 233, 237 (Tex.App.-Forth Worth 1996, writ denied) (thirteen month delay in bringing suit excessive as matter of law when plaintiff offered no explanation for delay), and LaGesse v. Prima-Care, Inc., 899 S.W.2d 43, 47 (Tex.App.-Eastland 1995, writ denied) (holding twelve month delay excessive as a matter of law where only reasons given were attorney delay), and Work v. Duval, 809 S.W.2d 351, 353-354 (Tex.App.-Houston [14th Dist.] 1991, no writ) (injury discovered four months prior to expiration of two-year limitations period irrelevant because plaintiff unreasonably delayed in filing suit for twenty-one months following discovery of injury).
The Estate urges that it is entitled to summary judgment even if Pech established a prima facie open courts violation because Pech, as a matter of law, did not bring her lawsuit within a reasonable time after she learned of the potential claim, and, therefore, is not entitled to relief from the open courts provision. We agree.

B. Pech Learned of Potential Claim
Pech's surgery was performed on May 20, 1996. Pech contends she did not discover the alleged injury until sometime between April 9, 1999 and April 23, 1999, almost three years after the surgery, when she was told that the lump was the same lump that Dr. Tavarez had reportedly removed in 1996. However, from our de novo review of the summary judgment evidence, we conclude the evidence establishes that discovery occurred no later than December 30,1998.
The summary judgment evidence provides that in November 1998 Pech had a routine mammogram while under the care of Dr. de la Garza. The radiologist reported that, as compared with the April 12, 1996 mammogram, the November 1998 mammogram showed no change in size and appearance of the lump in the left breast. Sometime between the November 1998 mammogram and December 30, 1998, when Pech saw Dr. Rodriguez-Aguero for a follow-up sonogram, she talked with Dr. de la Garza. During the telephone conversation *287 he informed her that the lump was the same lump. Pech testified at her deposition that when Dr. de la Garza first told her, she "almost lost it," "[i]t had been there for two years," and she was shocked and angry at Dr. Tavarez because he had left the lump. The evidence also establishes that in March 23, 1999, Pech discussed the possibility of this being the same lump with Dr. Hunter, and, in early April 1999, Pech ordered copies of her medical records from the Tavarez Clinic.
Based on the above, taking as true all evidence favorable to Pech and indulging every reasonable inference in Pech's favor, see Cathey, 900 S.W.2d at 341; Nixon, 690 S.W.2d at 549, we conclude, as a matter of law, that discovery occurred no later than December 30, 1998. Pech's claim in response to the motion for summary judgment that she did not discover the purported wrongful conduct until sometime between April 9, 1999 and April 23, 1999 when a physician informed her that the lump was the same lump that Dr. Tavarez was to have removed in 1996, is not supported by the summary judgment evidence.

C. Due Diligence in Filing Lawsuit
Based on a discovery date of December 30, 1998, and a filing date of March 13, 2000, Pech waited fourteen months after discovery to file her lawsuit. She asserts that her delay was reasonable. We disagree.
While we sympathize with Pech about her personal and family concerns, we conclude that, as a matter of law, Pech did not file her suit against the Estate within a reasonable period of time. A reasonable delay is allowed for investigation, preparation and filing the claim after the injury is discovered. Gagnier, 17 S.W.3d at 745; see DeRuy, 995 S.W.2d at 752. The fourteen month delay was not for that purpose.
During that interval Pech helped with family matters, a friend's health concerns, and personal health problems. After discovery, Pech briefly cared for her parents. Her father died a few months later, and Pech attended to the preparation of various services for him in Texas and in his home state of Minnesota. During this fourteen month delay, Pech also experienced health problems of her own unrelated to the surgery at issue, including a broken arm and sprained ankle that occurred while playing tennis. Pech also asserts the delay was reasonable because of health concerns of other family members and a friend.
We cannot conclude ordinary life experiences can be argued as legitimate bases for delaying the filing of a lawsuit. Moreover, Pech spent the summer months at her home in Minnesota, waiting until she returned to her winter home in Texas, nine months after discovery, before seeking the assistance of an attorney. Pech does not complain that any part of the delay was because she was recovering from the surgery at issue. See Gagnier, 17 S.W.3d at 745; DeRuy, 995 S.W.2d at 753. Also, her medical records were provided to her immediately upon request. See Gagnier, 17 S.W.3d at 745.
Pech knew about her alleged injury on December 30, 1998, fourteen months before she brought suit on March 13, 2000. She offered no valid explanation for the delay; the unreasonableness of the delay admits no other conclusion. See DeRuy, 995 S.W.2d at 752-53. Pech failed to use due diligence when she delayed fourteen months after she learned the lump had not been removed to file her claim. Therefore, even taking as true Pech's assertion that she could not have sued within the two-year limitations period, the open courts provision does not save her claim. *288 Accordingly, we overrule appellant's first issue.[2]

IV. Summary Judgment Valid as to Personal Representative
Pech contends by her second point of error that the trial court erred in dismissing this case in its entirety because Joan Tavarez, as executrix or personal representative of the Estate was not a moving party for the summary judgment. An estate of a decedent is not a legal entity and may not sue or be sued as such. Price v. Estate of Anderson, 522 S.W.2d 690, 691 (Tex.1975). However, if the estate's personal representative participates in the case, the judgment involving the estate may be valid. See Embrey v. Royal Ins. Co. Of Am., 22 S.W.3d 414, 415 n. 2 (Tex.2000) (citing Bernstein v. Portland Sav. & Loan Ass'n, 850 S.W.2d 694, 699 (Tex.App.-Corpus Christi 1993, writ denied)) (disapproved on other grounds by Crown Life Ins. Co. v. Casteel, 22 S.W.3d 378, 388-89 (Tex.2000)). In this case, Pech filed suit against both the Estate and Joan Tavarez, its executrix or personal representative. Mrs. Tavarez and the Estate made general appearances in this case. It is undisputed that Mrs. Tavarez, the personal representative of the Estate, participated in the case. Thus, we conclude that, although the motion for summary judgment identified the Estate as the movant, the summary judgment is valid as to the personal representative, Mrs. Tavarez.[3] Pech's second point is overruled.

V. Fraud Claim Not Raised
Finally, by her third point of error, Pech contends that the trial court erroneously failed to consider her second amended original petition in rendering its decision. In her briefing, Pech describes one of Dr. Tavarez's acts as negligence or fraud. However, we have reviewed Pech's second amended petition and find no mention of fraud or the elements of fraud in the petition. Her factual recitation is expanded in her amended petition; however, the facts support her claim for negligence, a cause of action mentioned repeatedly throughout the document. The Estate's motion for summary judgment addressed Pech's negligence claim. See Tex.R. Civ. P. 166a(c) (motion shall state specific grounds therefor). Accordingly, we overrule Pech's third point of error.

VI. Conclusion
The judgment of the trial court is affirmed.

[2]  We also overrule the third point of error to the extent Pech contends she did not discover the alleged claims until more than two years after surgery and treatment, thus, her claim should not be barred.
[3]  We note Pech did not sue Mrs. Tavarez in her individual capacity and did not assert claims against her individually; allegations of malpractice were asserted only against Dr. Tavarez.
