Appellee, Tat Man Chung, was injured when the vehicle he was driving collided with a vehicle operated by appellant, Kip Donavan Earns. In this personal injury action brought by Chung to recover damages for his injuries, Chung alleged that Earns was negligent “in operating a vehicle while under the influence of alcohol.” Earns denied this allegation in his answer.
Chung subsequently filed an application for the court’s permission to take the deposition of the physician who treated Earns in the hospital emergency room immediately following the accident; Chung also sought production of Earns’ medical records “to show [Earns’] condition and particularly his state of intoxication.” Earns resisted, contending that the physician-patient privilege in Iowa Code section 622.10 (1993) protected this evidence from disclosure to third parties. The district court granted Chung’s application, allowing the discovery.
We granted Earns’ request to take this interlocutory appeal and now reverse the district court’s ruling. We conclude a plaintiff cannot effect a waiver of the defendant’s physician-patient privilege by making the defendant’s medical condition an element or factor of the plaintiffs case.
I. Physicicmr-Patient Privilege.
The ultimate objective of a majority of the rules of evidence is the elucidation of truth by excluding unreliable or prejudicial evidence. 1 Kenneth S. Braun et al., McCormick on Evidence § 72, at 268-69 (John W. Strong ed., 4th ed. 1992) (hereinafter “McCormick on Evidence"). The rules of privilege, however, have a different goal. They are not designed to facilitate the fact-finding process; they exist to promote an interest in protecting “certain communications from disclosure even though the confidences may otherwise be admissible.” 7 James A. Adams & Kasey W. Kincaid, loica Practice: Evidence § 501.1, at 186 (1988) (hereinafter “Ioiva Practice”); see also McCormick on Evidence § 72, at 269.
The physician-patient privilege was unknown to the common law; however, it has been part of a testimonial privilege recognized in Iowa’s statutes since the 1851 Iowa Code. Iowa Practice § 504.2, at 218. This statutory privilege is contained in Iowa Code section 622.10:
A practicing ... physician ..., who obtains information by reason of the person’s employment, ... shall not be allowed, in *149 giving testimony, to disclose any confidential communications properly entrusted to the person in the person’s professional capacity, and necessary and proper to enable the person to discharge the functions of the person’s office according to the usual course of practice or discipline. The prohibition does not apply to cases where the person in whose favor the prohibition is made waives the rights conferred; nor does the prohibition apply to physicians ... in a civil action in which the condition of the person in whose favor the prohibition is made is an element or factor of the claim or defense of the person or of any party claiming through or under the person. The evidence is admissible upon trial of the action only as it relates to the condition alleged.
Iowa Code § 622.10 (1993). The statutory rule of testimonial exclusion has been extended by rule to the discovery of confidential communications.
See
Iowa R.Civ.P. 122(a) (excluding privileged materials from the scope of permissible discovery);
Squealer Feeds v. Pickering,
Section 622.10 is intended to promote uninhibited and full communication between a patient and his doctor so the doctor will obtain the information necessary to competently diagnose and treat the patient.
State v. Deases,
The parties do not dispute the requested testimony and documents fall within the physician-patient privilege.
See State v. Eldrenkamp,
nor does the prohibition apply to physicians ... in a civil action in which the condition of the person in whose favor the prohibition is made is an element or factor of the claim or defense of the person or of any party claiming through or under the person.
Iowa Code § 622.10 (1993) (emphasis added). The question we must decide is whether Earns’ alleged intoxication is “an element or factor of [Kams’] defense”? For the reasons that follow we hold that although Earns’ intoxication may be an element or factor of Chung’s claim against Earns, it is not an element or factor of Earns’ defense of that claim.
II. Scope ofRevieiu.
We review the trial court’s interpretation of section 622.10 for errors of law.
Deases,
III. Patient-Litigant Exception.
Chung argues the exception abrogates the physician-patient privilege “when the condition of a party is in issue.” The statute’s plain language, as well as its underlying purpose, oppose Chung’s interpretation.
The statute requires the condition be an element or factor of the claim or defense
of the person claiming the privilege.
The denial of an element or factor of one’s
opponent’s
case does not make that element or factor part of the case of the person making the denial. In other words, even though Earns denied he was intoxicated, his intoxication remains an element or factor in Chung’s claim. We can state with confidence that if Earns’ intoxication were not an element or factor in
Chung’s
claim, it would not be an issue in the case; Earns would have no reason to make it a factor or element in
his
case. Therefore, the mere act of denying the existence of an element or factor
of an adversary’s
claim does not fall within the statutory language.
Peisach v. Antuna,
Any other interpretation of the patient-litigant exception would severely undermine the purpose of the statutory privilege. By choosing to adopt the privilege, the legislature made the policy judgment that complete and honest communications between a physician and patient would be enhanced by making these communications confidential. The interpretation sought by Chung would seriously thwart the legislature’s goal of enhancing candid physicián-patient communications. If a patient knows an adversary in a civil suit would have the power to make the patient’s medical condition an issue in the case, the patient is more likely to be guarded in the information he shares with his physician.

*151
There are few cases in which an imaginative lawyer could not make the opposing party’s physical or mental condition at least a factor in the case. If such tactics were sufficient to trigger the exception, there would be little left of the privilege.
See Peisach,
In contrast, our interpretation of the patient-litigant exception does not undermine the purpose of the statutory privilege; the existence of the exception will not inhibit communication between a patient and his doctor because the patient knows his statements will remain confidential unless he affirmatively and voluntarily chooses to reveal them by raising his condition as an element or factor of any claim or defense the patient makes. See McCormick on Evidence § 103, at 384 (policy considerations support a finding of waiver only when the patient has voluntarily placed his condition in issue in a judicial proceeding). 3
We recognize our holding will preclude the discovery and admission of relevant evidence. That fact, however, is no reason not to apply the privilege, for it is in precisely this situation that the privilege is intended to operate.
Dillenbeck,
IV. Disposition.
In summary, we hold Earns’ denial of Chung’s allegation that Earns was intoxicated at the time of the accident did not make Earns’ physical condition an element or factor of his defense. Therefore, the physician-patient privilege applies. The trial court erred in ordering discovery of privileged information. We reverse and remand for trial.
REVERSED AND REMANDED.
Notes
. The
Eldrenkamp
case is distinguishable from the case we decide today. In
Eldrenkamp,
we held that blood test results of a person involved in a vehicular homicide did not fall within the physician-patient privilege.
Eldrenkamp,
. This effect could be most apparent for patients who have an occupation that exposes them to the risk of professional liability suits. Physicians, accountants, engineers and lawyers, for example, *151 might be particularly reluctant to share information with their doctor that might be damaging to their defense should they be sued by one of their own patients or clients. Such professionals may choose to forego treatment altogether, certainly not a result intended by the legislature when it adopted a physician-patient privilege.
. One cannot say a party has voluntarily chosen to make his condition an issue in the case by simply denying his adversary's allegation:
Were we to adopt [this] argument, the defendant would be placed in the position of either admitting plaintiff's allegations of intoxication, or else foregoing the privilege. We do not believe that the physician-litigant exception was intended to work such a result.
