CNH Industrial America, LLC (CNH) and Ace American Insurance Co.1
appeal the district court order reversing the workers’ compensation
commissioner’s denial of Anthony Culpepper’s claim for benefits. They contend
substantial evidence supports the commissioner’s findings that Culpepper failed to
show he sustained and gave timely notice of a compensable injury. Because we
reach the same conclusions as the district court, we affirm its judicial review ruling.
I. Background Facts and Proceedings.
In 2004, Culpepper began working for CNH, which produces tractors and
other heavy machinery. He started on the production line, installing motor valves
in heavy machinery. After herniating a disc while working in 2007, Culpepper was
moved to a material specialist position. Although Culpepper used a forklift to
perform most of his duties, the job required frequent bending, twisting, and flexing
of his neck.
Around 2017 or 2018, CNH reassigned Culpepper to work as a quality
specialist. In this position, Culpepper climbed on top of, inside of, and under the
machinery to ensure its quality. The work involved moving his head from side to
side, crouching, crawling, and manipulating objects with his hands and fingers.
Before Culpepper’s last job reassignment, he had experienced pain in his
lower back, shoulders, and arms. After he became a quality specialist, Culpepper
began experiencing pain that originated in his neck. He described this as tingling
numbness and pain that began on the left side of his neck and radiated down to

his wrist. Culpepper claims that the pain became steady but remained
manageable for one or two years before becoming intolerable in May or
June 2021. Culpepper claims that he reported work-related tingling and numbness
in his arm to CNH’s health services when it became intolerable, although he could
not recall the exact date of his report. According to Culpepper, CNH provided
palliative care like heat and ice before returning him to work.
In June 2021, Culpepper reported his symptoms to his physician. That
September, CNH referred Culpepper to a doctor who administered a cervical
epidural steroid injection for cervical and left arm radicular pain. Three weeks later,
another CNH doctor referred Culpepper to Dr. Abernathey, a neurosurgeon. After
reviewing Culpepper’s MRI, Dr. Abernathey found modest degenerative changes
at multiple levels of the spine. But he also found lateral disc extrusion at
Culpepper’s C6-7 disc, which Dr. Abernathey recommended treating surgically
with an anterior cervical discectomy and fusion.2
Culpepper petitioned for workers’ compensation benefits in February 2022.
For injury dates, Culpepper alleged “06/08/21, approximate; 09/03/21; 10/29/21
(cumulative).” After an arbitration hearing, the deputy worker’s compensation
commissioner found that Culpeper failed to show the disc extrusion was related to
his work activities. The deputy concluded that Culpepper’s condition was the result
of the natural breakdown of his cervical spine due to a preexisting degenerative
condition. In the alternative, the deputy held that even if Culpepper’s injury was

related to his work activities, his failure to provide CNH with notice of his injury bars
recovery. Culpepper appealed to the worker’s compensation commissioner, who
affirmed the deputy’s decision.
Culpepper petitioned the district court for judicial review. The district court
found the agency failed to address highly relevant and uncontroverted expert
opinion evidence from Dr. Abernathey. As a result, it concluded the agency’s
actions were “unreasonable, arbitrary, capricious, an abuse of discretion, and the
product of illogical reasoning.” The court also found the agency “relied on a patent
misinterpretation” of other evidence provided by Dr. Abernathey. On this basis,
the court granted Culpepper’s petition, reversed the agency’s findings, and
remanded to the agency for a new order consistent with its ruling. The defendants
appeal.
II. Scope and Standard of Review.
Our review of agency decisions is governed by Iowa Code section 17A.19
(2024). “We apply the standards set forth in Iowa Code chapter 17A in our judicial
review of agency decision-making to determine whether our conclusion is the
same as the district court.” Brewer-Strong v. HNI Corp., 913 N.W.2d 235, 242
(Iowa 2018). The district court may properly grant relief if agency action prejudiced
the substantial rights of the petitioner and that action falls under one of the criteria
of section 17A.19(10). Id. If we reach the same conclusion as the district court,
we affirm. Id.
Whether an employee sustained an injury arising out of and in the course
of their employment is fact question vested in the discretion of the worker’s
compensation commissioner. Bridgestone Americas, Inc. v. Anderson, 4 N.W.3d 5
676, 681 (Iowa 2024). We affirm the agency’s findings if supported by substantial
evidence. Id. We are not concerned about whether the evidence could support a
different conclusion. Id. The question is whether substantial evidence supports
the findings made by the agency when the record is viewed as a whole. Id.
III. Causation.
The defendants first challenge the district court’s reversal of the agency’s
causation finding. The district court determined that the record does not support
the agency’s finding that Culpepper’s condition is the result of a preexisting
degenerative condition and unrelated to his work activities. The court found the
deputy commissioner misconstrued Dr. Abernathey’s statements about the cause
of Culpepper’s condition and ignored Dr. Abernathey’s stated medical opinion on
his work activity aggravating his cervical spine, resulting in the need for surgery.
The record shows that Dr. Abernathey provided statements about
Culpepper’s injury in November 2021, January 2022, and March 2022. The
deputy commissioner discusses the November 2021 and March 2022 statements
in the arbitration decision but notably omits any discussion of the January 2022
statement, in which Dr. Abernathey opined “within a reasonable degree of medical

III. Causation.
The defendants first challenge the district court’s reversal of the agency’s
causation finding. The district court determined that the record does not support
the agency’s finding that Culpepper’s condition is the result of a preexisting
degenerative condition and unrelated to his work activities. The court found the
deputy commissioner misconstrued Dr. Abernathey’s statements about the cause
of Culpepper’s condition and ignored Dr. Abernathey’s stated medical opinion on
his work activity aggravating his cervical spine, resulting in the need for surgery.
The record shows that Dr. Abernathey provided statements about
Culpepper’s injury in November 2021, January 2022, and March 2022. The
deputy commissioner discusses the November 2021 and March 2022 statements
in the arbitration decision but notably omits any discussion of the January 2022
statement, in which Dr. Abernathey opined “within a reasonable degree of medical
certainty that [Culpepper]’s work activities . . . as part of his job as a quality
specialist resulted in an aggravation to his cervical spine necessitating his need
for surgery.” The defendants suggest that the March 2022 statements reflect a
change in Dr. Abernathey’s opinion from January 2022, justifying its exclusion. In
the alternative, the defendants argue that the statements are in conflict and thus it
is for the agency to decide which statements to credit.
In March 2022, Dr. Abernathey agreed with three statements: 6
• He is unaware of any “specific” work activity or work incident that would have caused injury to Culpepper’s cervical spine. • Diagnostic studies of Culpepper’s cervical spine “clearly show long- standing degenerative changes that would have long pre-dated June of 2021.” • It is his medical opinion that Culpepper’s need for the cervical fusion surgery: (1) “is more likely than not” “related” to his long-standing degenerative condition, (2) would have been inevitable, and (3) is not caused by a work injury from 2021.
These statements are not irreconcilable with Dr. Abernathey’s opinion that
Culpepper’s work activity aggravated his condition such that he needs surgery.
First, Culpepper’s condition was aggravated by years of ongoing work activities
rather than a discrete injury that occurred in 2021 or earlier. The statements
reconcile when “specific” is read as “discrete.” Second, there is no dispute that
Culpepper has a degenerative condition that existed before June 2021. Despite
its existence, the record shows that Culpepper’s cervical spine was asymptomatic
before his reassignment to a quality specialist position.3 Finally, Dr. Abernathey’s
opinion that Culpepper’s need for surgery is “related” to his degenerative condition 4
or would have been inevitable does not contradict his opinion that the need for
3 The defendants cite Dr. Abernathey’s notes on Culpepper’s medical history, which states that Culpepper “experienced cervical, thoracic, and lumbar pain for many years dating back to 2007.” This history is only inconsistent if interpreted to mean that Culpepper has experienced each category of pain since 2007. But as summarized in the deputy commissioner’s arbitration decision, Culpepper’s medical records show he only reported thoracic, lumbar, and arm pain before 2021. Although Culpepper experienced cervical pain as early as 2017 or 2018, he believed it was not a serious problem and that he could work through it. 4 The deputy summarized Dr. Abernathey’s statement as finding “it was more likely
than not that the need for cervical fusion surgery being proposed would have been related to [Culpepper]’s long-standing degenerative condition rather than any work injury.” (Emphasis added.) The emphasized text is neither included in Dr. Abernathey’s signed statement, nor is it a necessary inference. Considering that this inference directly contradicts the opinion Dr. Abernathey provided just two months earlier, which he never disavowed, it is illogical to infer that Dr. Abernathey found Culpepper’s condition is unrelated to work activity. 7
surgery results from work activity that aggravated that condition. See McSpadden
v. Big Ben Coal Co., 288 N.W.2d 181, 191–92 (Iowa 1980) (“[T]he fact that the
normal aging process may produce the ailment from which a claimant suffers as
an actual result from his employment experience does not operate to bar a finding
of disability.”).
The rule in Iowa is that an employee is entitled to full compensation when
workplace activity aggravates a preexisting condition that did not previously cause
a degree of disability. Floyd v. Quaker Oats, 646 N.W.2d 105, 110 (Iowa 2002);
accord Rose v. John Deere Ottumwa Works, 76 N.W.2d 756, 761 (Iowa 1956) (“If
plaintiff was diseased and his condition was aggravated, accelerated, worsened or
‘lighted up’ by the injury so it resulted in the disability found to exist plaintiff was
entitled to recover.”). As noted above, the undisputed evidence shows that
Culpepper was asymptomatic of cervical pain before he began working as a quality
specialist. Thus, viewing the entire record before the agency, we agree with the
district court’s conclusion that the agency’s causation finding is not supported by
substantial evidence.
IV. Notice.
We turn then to the defendants’ notice claim. As an alternative ground for
denying Culpepper’s claim for benefits, the deputy found that Culpepper failed to
provide CNH with notice of his injury within ninety days of the date of the
occurrence as required by Iowa Code section 85.23 (2021):
Problematically, claimant did not provide a date upon which he reported his injury to his employer. On June 8, 2021, claimant sought treatment for neck pain but he related that the pain had been ongoing one or two years. He testified that he reported this pain previous to June 8, 2021, but no action was taken. However, he also 8
testified that his reports of pain to the health staff with defendant employer led him to an appointment with Dr. Milani that took place in September. There is no explanation in the record as to why the medical staff acted differently to the pre-June 8, 2021, pain complaints. There is no evidence of actual notice nor imputed notice. The lack of notice would prevent recovery in this case even if liability was established.
Iowa Code section 85.23 requires that employees give notice of an injury to
an employer within ninety days of the date they knew or should have known that
the injury was work-related. Failure to do so bars recovery. Iowa Code § 85.23.
Legislative amendments enacted in 2017 clarified this requirement, see 2017 Iowa
Acts ch. 23, § 3, codifying the manifestation test previously adopted in cumulative
injury cases, see Meyer v. IBP, Inc., 710 N.W.2d 213, 221 (Iowa 2006)
(“‘Manifestation’ is best characterized as ‘the date on which both the fact of the
injury and the causal relationship of the injury to the claimant’s employment would
have become plainly apparent to a reasonable person.’” (citation omitted)). See
also generally Tweeten v. Tweeten, 999 N.W.2d 270, 279–82 (Iowa 2023)
(discussing the legislative amendment of section 85.26, which added identical
language for purposes of computing the statute of limitations). Because repetitive-
trauma injuries or cumulative injuries develop over time, it can be difficult to identify
an injury date. Tweeten, 999 N.W.2d at 279. Factors in determining when the
injury manifests itself include “absence from work because of inability to perform,
the point at which medical care is received, or others, none of which is necessarily
dispositive.” Meyer, 710 N.W.2d at 221 (citation omitted).
Because lack of notice is an affirmative defense, the burden of proof is on
the defendants to show Culpepper failed to provide timely notice of his injury. See
PMX Indus. v. Reich, No. 12-1824, 2013 WL 2371191, at *10 (Iowa Ct. App. 9
May 30, 2013). The district court concluded that the deputy erred by requiring
Culpepper to provide a precise date of injury to prove notice. Culpepper testified
that he informed and sought treatment from CNH’s health services for tingling that
began in his neck and radiated down his arm before seeing his personal physician
in June 2021. As a result, CNH sent Culpepper to see an occupational doctor in
August and September 2021. The defendants failed to present any evidence
rebutting this testimony.
We agree that the agency erred by placing the burden on Culpepper to
show he provided notice of his injury rather than requiring the defendants to prove
lack of notice as an affirmative defense. Based on the record before the agency,
Culpepper knew or should have known that he had a work-related injury by
June 2021. Culpepper’s testimony that he sought treatment for his pain from
health services before June 2021 is undisputed. Even discounting Culpepper’s
testimony, CNH knew of Culpepper’s condition when it referred him for medical
treatment. His first appointment with an occupational doctor was in August 2021,
which falls within the ninety-day window set by section 85.23.
V. Conclusion.
Because we reach the same conclusions as the district court, we affirm.
AFFIRMED.
