Before Gundrum, P.J., Neubauer and Lazar, JJ.

Per curiam opinions may not be cited in any court of this state as precedent 

or authority, except for the limited purposes specified in WIS. STAT. RULE 809.23(3). 

¶1 PER CURIAM. Mary A. Hensley and Spriggie N. Hensley, Sr., pro 

se, appeal from an order granting summary judgment for Froedtert South, Inc. and 

various Froedtert entities and doctors (collectively, “Froedtert”). The Hensleys 

assert that the circuit court erred in dismissing their medical malpractice and 

corporate negligence claims based on their failure to disclose an expert witness 

and their failure to provide evidence supporting their allegation that Mary’s 

medical records were falsified. We reject the Hensleys’ arguments and affirm. 

BACKGROUND

¶2 On June 22, 2020, the Hensleys sought medical treatment for Mary 

at Froedtert South – Somers Clinic (“Froedtert South”). According to the 

complaint, Mary presented symptoms to a physician’s assistant, including lower 

abdominal and back pain, bloating, nausea, diarrhea, vomiting, constipation, and 

recurring fever. The physician’s assistant ordered x-rays that confirmed the 

distended appearance of Mary’s abdomen, but she did not order other diagnostic 

testing. The assistant and her supervising doctor treated Mary’s condition as a 

mild digestive disorder and sent her home with instructions to “adhere to a ‘clear 

liquid’ diet.” The Hensleys returned the next day because Mary’s pain had not 

subsided. Mary was then seen by an advance practice nurse practitioner who was 

supervised by the same doctor and who also diagnosed Mary with mild digestive 

disorder and instructed her to adhere to a bland diet. 
No. 2022AP588

¶3 On June 25, 2020, the Hensleys returned to Froedtert South for an 

appointment with a primary care physician. Mary’s condition had continued to 

deteriorate and she was in “severe distress.” The physician refused to provide 

treatment because the Hensleys arrived six minutes late. Spriggie then took Mary 

to the Kenosha Hospital Emergency Department, where an emergency room 

physician observed acute pain, fever, disorientation, and physical distress and 

ordered various diagnostic tests, which showed abnormal values. The ER 

physician ordered an ultrasound of Mary’s abdomen and a CT scan, which 

together showed that Mary was suffering from a “prominent inflammatory 

reaction” likely due to appendicitis. The following day, Mary was transported by 

“Flight for Life” to Pleasant Prairie Hospital where Dr. Mejal Jandali performed 

an appendectomy on Mary.

¶4 The Hensleys filed suit on September 7, 2021. They asserted claims 

for medical malpractice and corporate negligence based on allegations that Mary 

suffered an injury as a result of Froedtert’s failure to “correctly diagnose” 

appendicitis and to timely provide treatment. Their Amended Complaint added a 

claim based on allegations that Froedtert “falsified and concealed” Mary’s health 

care records related to her June 2020 visits. After several months of discovery, the 

parties filed cross-motions for summary judgment. Following a hearing, the 

circuit court ruled in favor of Froedtert and dismissed all three claims. 

¶5 The circuit court dismissed the Hensleys’ medical malpractice claim 

because they had failed to disclose any expert witnesses, remarking that “case law 

does require that ... an expert testify as to what the standard of care is.” The court 

rejected the Hensleys’ argument that their medical malpractice allegations fell 

within the knowledge and understanding of a layperson and did not require expert 

testimony. The court also rejected the Hensleys’ contention that they could call 
No. 2022AP588

4

Jandali or any of the other treating physicians to provide expert testimony to 

support the Hensleys’ claims, stating that “you cannot ask them their opinions [as 

an expert] unless they consent to that and agree to that in a contract.” The court 

concluded the same failure to disclose an expert witness doomed the Hensleys’ 

claim of corporate negligence, because that claim “comes out of ... medical 

negligence.” The court rejected the Hensleys’ argument that expert testimony was 

unnecessary because Froedtert’s employees did not comply with its own policies 

and procedures. 

¶6 Finally, the circuit court confirmed with the Hensleys that their false 

records claim was based solely on differences between two versions of a summary

they had received on June 23, 2020. The court determined that the Hensleys had 

not presented evidence supporting their claim that Froedtert falsified Mary’s aftervisit summary from her June 23, 2020 visit to Froedtert South. The court also 

concluded the Hensleys had failed to allege damages associated with this claim. 

The Hensleys appeal, arguing that the circuit court erred in dismissing their 

claims.

DISCUSSION

¶7 Appellate courts review a grant or denial of summary judgment de 

novo using the same methodology as the circuit court. M&I First Nat’l Bank v. 

Episcopal Homes Mgmt., Inc., 195 Wis. 2d 485, 496, 536 N.W.2d 175 (Ct. App. 

1995); WIS. STAT. § 802.08(2) (2021-22).

 This court must first examine the 

complaint to determine whether it states a claim; we then must examine the

noted.
No. 2022AP588

answer to determine whether it presents a material issue of law or fact. See 

Guenther v. City of Onalaska, 223 Wis. 2d 206, 210, 588 N.W.2d 375 (Ct. App. 

1998). If the pleadings are sufficient, our next step is to determine whether the 

moving party’s affidavits and other proof make out a prima facie case for 

summary judgment. See Swatek v. County of Dane, 192 Wis. 2d 47, 62, 531 

N.W.2d 45 (1995). “If the moving party has made a prima facie case for summary 

judgment,” the court then examines “the affidavits and other proof of the opposing 

party” to decide whether there are disputed material facts. Id. The moving party 

need only explain the basis for its motion for summary judgment and identify the

portions of “the pleadings, depositions, answers to interrogatories, and admissions 

on file, together with the affidavits, if any,” that it believes show there is no

genuine issue of material fact; “the moving party need not support its motion with 

affidavits that specifically negate the opponent’s claim.” Transportation Ins. Co. 

v. Hunzinger Constr. Co., 179 Wis. 2d 281, 292, 507 N.W.2d 136 (Ct. App. 1993)

(citation omitted). 

I. Medical Malpractice 

¶8 To succeed on a claim of medical malpractice, a plaintiff must prove 

a negligent act or omission that is below the standard of care and causes an injury. 

See Paul v. Skemp, 2001 WI 42, ¶17, 242 Wis. 2d 507, 625 N.W.2d 860; J.W. v. 

B.B., 2005 WI App 125, ¶9, 284 Wis. 2d 493, 700 N.W.2d 277. Generally, expert 

testimony is necessary concerning matters involving special knowledge, skill, or 

experience on subjects that are not within the realm of the jurors’ ordinary 

experience and that require special learning, study, or experience. Cramer v. 

Theda Clark Mem’l Hosp., 45 Wis. 2d 147, 150, 172 N.W.2d 427 (1969). In Olfe 

v. Gordon, 93 Wis. 2d 173, 180, 286 N.W.2d 573 (1980), our supreme court made 

clear that the medical standard of care is one of these subjects: “[i]n medical 
No. 2022AP588

malpractice actions, Wisconsin law generally requires the plaintiff to introduce 

expert testimony as to the standard of care and the defendant’s departure from it.” 

See also Burnett v. Alt, 224 Wis. 2d 72, 83-84, 589 N.W.2d 21 (1999). Without 

testimony from an expert, a jury lacks a frame of reference to determine whether 

the defendant failed to exercise the degree of care and skill of a reasonably prudent 

doctor. See id.

¶9 Our supreme court discussed expert testimony in medical 

malpractice cases extensively in Alt and held that an expert witness is required in 

such cases because “a lay person, medically untrained and uneducated, is in no 

position to answer [questions about what symptoms are normal in a given patient] 

with anything other than a speculative guess.” 224 Wis. 2d at 84. However, the 

court noted that WIS. STAT. § 907.06 explicitly recognizes an expert witness’s 

right to refuse to provide expert testimony when appointed by the court. See Alt,

224 Wis. 2d at 86. This express statutory grant implies a privilege for an expert to 

refuse to testify if called by a litigant; “[i]t makes little if any sense to conclude 

that a litigant has greater rights than a court with respect to obtaining testimony 

from experts.” Id.

¶10 The Hensleys argue that the standard of care governing their medical 

malpractice claim falls within the knowledge and understanding of the average 

layperson, and thus does not require expert testimony. To the extent expert 

testimony is required, the Hensleys argue, they would have called Jandali (Mary’s 

surgeon) and the named defendant doctors to provide expert testimony at trial in 

support of their claim. 

¶11 We reject each of the Hensleys’ contentions, beginning with their 

assertion that no expert testimony is required in support of their medical 
No. 2022AP588

negligence claim. The diagnosis of appendicitis is a question that does not lie 

within the knowledge and experience of a layperson and appendicitis symptoms 

are not a matter of common knowledge or experience such that a layperson would 

have been able to recognize the malady upon presentation. Consistent with Alt,

we conclude that a diagnosis of appendicitis involves specialized knowledge and 

any testimony regarding the standard of care applicable to that diagnosis must 

come from an expert witness with sufficient knowledge and training. See Alt, 224

Wis. 2d at 83. 

¶12 Moreover, an expert witness must have qualified knowledge about 

the topic on which he or she will be testifying. The Hensleys have failed to 

demonstrate that Jandali, a surgeon, is a qualified expert, under WIS. STAT.

§ 907.02, to testify on the standard of care for a physician assistant, emergency 

room doctor, or a nurse practitioner—the occupations of Mary’s medical providers 

on the dates the alleged negligence occurred. Testimony establishing the 

applicable standard of care must come from an expert with a similar training and 

knowledge of the defendant providers. See Carney-Hayes v. Northwest Wis. 

Home Care, Inc., 2005 WI 118, ¶45, 284 Wis. 2d 56, 699 N.W.2d 524. 

¶13 On that point, the Hensleys cannot compel any of the named 

defendants to offer opinions on the standard of care. See Alt, 224 Wis. 2d at 90. 

Absent exceptional circumstances, a medical witness who is unwilling to testify as 

an expert—and the fact witnesses here apparently are unwilling—is not required 

to give an opinion on the applicable standard of care. See id. at 89. If the 

Hensleys were to call the named defendants, their testimony would be limited to 

describing their own conduct in treating Mary. For these reasons, the circuit court 

properly dismissed the Hensleys’ medical malpractice claim. 
No. 2022AP588

II. Corporate Negligence

¶14 The Hensleys also argue the circuit court erred by dismissing their 

corporate negligence claim. The Hensleys assert that Froedtert “not only held 

itself out as a licensed health care facility[,] but gave its specific assurance 

[through its webpage] that any patient presenting to its Immediate Care Services 

with severe illness or injury would be directed to the ‘Emergency Department.’” 

According to the Hensleys, this statement on Froedtert’s webpage “is essentially a 

‘corporate referral policy’ which imposes a duty upon [Froedtert] to implement 

measures sufficient to ensure [the policy] is carried out by [Froedtert’s]

employees.” They further argue Froedtert failed to comply with those policies and 

procedures. 

¶15 The Hensleys fail to appreciate that the standard of care against 

which alleged negligence must be measured cannot be fixed by a defendant’s 

adoption of private rules. See Marolla v. American Fam. Mut. Ins. Co., 38 

Wis. 2d. 539, 543-44, 157 N.W.2d 674 (1968). “Such rules may require more, or 

they may require less, than the law requires; and whether a certain course of 

conduct is negligent, or the exercise of reasonable care, must be determined by the 

standard fixed by law, without regard to any private rules of the party.” Id.

(citation omitted). In other words, the standard of care is determined by what a 

reasonable hospital would do in the same or similar circumstances, not by the 

hospital’s policies. See Johnson v. Misericordia Cmty. Hosp., 99 Wis. 2d 708, 

739-40, 301 N.W.2d 156 (1981).

¶16 The question of what a reasonable hospital would do under similar 

circumstances again implicates the need for expert testimony. Id. The 

reasonableness of Froedtert’s protocols and/or conduct in determining whether 
No. 2022AP588

9

Mary needed to be referred to the Emergency Department does not fall within the 

knowledge of a layperson. Consistent with the foregoing discussion, the Hensleys 

were required to name a witness to establish the standard of care applicable to a 

reasonable hospital.

¶17 Further, as pointed out in Miller v. Wal-Mart Stores, Inc., 219 

Wis. 2d 250, 261-62, 580 N.W.2d 233 (1998), a claim of corporate negligence 

must be supported by evidence establishing a causal nexus between the corporate 

conduct and the underlying act of an employee or agent that caused injury. Here, 

the Hensleys needed an expert witness to support their underlying negligence 

claims against the hospital or its providers and to show a nexus between Mary’s 

injuries and Froedtert’s policy. But, as with their medical malpractice claim, the 

Hensleys failed to show that they were prepared to call an expert witness in order 

to prove this causation. For these reasons, the circuit court properly dismissed the 

Hensleys’ corporate negligence claim. 

III. “Falsification” and “Concealment” of “Patient Health Care Records” 

¶18 Finally, the Hensleys argue that the circuit court erred in dismissing 

their claim for “falsification” of Mary’s health care records. Specifically, they 

contend that Mary’s after-visit summary document (“AVS”) was altered to omit 

critical information concerning the severity of Mary’s true condition. The 

Hensleys’ sole basis for this allegation is that the AVS they received following the 

June 23, 2020 visit did not include the following language that appeared in the 

final version generated a few minutes later on the same day:

Regarding your abdominal discomfort, though an extensive 

workup does not seem warranted at this time, remember 

that the Immediate Care clinic is limited and serious causes 

have not been ruled out for you today. Therefore if your 

pain worsens in any way or you develop other symptoms 
No. 2022AP588

10

including but not limited to fever, vomiting, chest pain, low 

back pain, or blood in the stool, you are to go to the ER for 

further evaluation immediately.

¶19 The Hensleys assert that this “falsification” violates WIS. STAT.

§ 146.83(4), which states that “[n]o person” may:

(a) Intentionally falsify a patient health care record. 

(b) Conceal or withhold a patient health care record with 

intent to prevent or obstruct an investigation or prosecution 

or with intent to prevent its release to the patient, to his or 

her guardian, to his or her health care provider with a 

statement of informed consent, or under the conditions 

specified in s. 146.82(2), or to a person with a statement of 

informed consent. 

(c) Intentionally destroy or damage records in order to 

prevent or obstruct an investigation or prosecution.

¶20 Froedtert asserts that the AVS is automatically generated by 

Froedtert’s electronic medical records system and that it is excluded from the 

statutory definition of “patient health care records.” Setting aside the latter 

question, we note that the record clearly shows that on June 23, 2020, the AVS 

was generated as part of an “in process” document with the preliminary version 

generated automatically at 3:43 p.m., and the final version generated at 3:46 p.m.

¶21 The Hensleys have failed to provide evidence of any intentional 

“falsification” under the statute. Additionally, both AVS documents were entered 

into the circuit court record by the Hensleys, and they have provided no evidence 

of Froedtert “withholding” or “concealing” either document. For at least these 

reasons, the circuit court properly dismissed the Hensleys’ claim based on 

“falsification” of patient heath care records.
No. 2022AP588

¶22 For the foregoing reasons, we affirm the circuit court’s order 

granting summary judgment. 

By the Court.—Order affirmed.
