OPINION
¶ 1 This special action arises from a personal injury lawsuit in which a treating physician refused to testify unless he was compensated as an expert witness. The superior court ordered Santiago Sanchez (Sanchez), the defendant below, to compensate the treating physician as an expert witness. The narrow issue we address is whether a treating physician’s testimony concerning diagnosis, treatment, and prognosis is expert testimony because it draws upon his or her skill, training, and experience as a doctor. For the following reasons, we accept jurisdiction of the special action petition and grant relief.
FACTS AND PROCEDURAL HISTORY
¶ 2 Heydy Santizo Hernandez (Hernandez) was involved in a motor vehicle accident with Sanchez in Scottsdale, Arizona. Hernandez sued Sanchez for personal injury damages resulting from the accident, and alleged that she required chiropractic treatment from Injury Chiropractic. As part of her prima facie ease, Hernandez would have to prove that she was injured, and that her treatment and
¶ 3 During discovery, Sanchez subpoenaed Dr. Hobbs to take his deposition. Dr. Hobbs filed a motion to quash the subpoena, or in the alternative, sought entry of a protective order limiting the scope of inquiry by defense counsel and requiring Sanchez to pay expert witness fees in advance. Dr. Hobbs sought to limit the issues to: (1) the care and treatment of Hernandez; (2) the documentation and record-keeping related to the care provided; (3) the reasonableness of the medical services provided; and (4) the philosophy and modalities of the type of chiropractic medicine engaged in by Dr. Hobbs regarding Hernandez’s medical condition. On October 17, 2012, Judge Gama granted the motion and agreed that Dr. Hobbs was an expert for purposes of Arizona Rule of Civil Procedure 26(b)(4)(A) & (C).
SPECIAL ACTION JURISDICTION
¶ 4 Special action jurisdiction is appropriate when a petitioner does not have an “equally plain, speedy, or adequate remedy by appeal.” Ariz. R.P. Spec. Act. 1(a); State ex rel. Romley v. Superior Court,
¶ 5 The petition presents a purely legal question of statewide importance affecting numerous cases. The lack of guidance in this area has resulted in conflicting superior court rulings. Consequently, we exercise our discretion and accept special action jurisdiction.
DISCUSSION
¶ 6 Sanchez asserts that he should not have been required to pay expert witness compensation of Dr. Hobbs because of his specialized chiropractic knowledge, even though he would only be testifying about his examination, treatment, bills, and chiropractic opinions formed during treatment of Hernandez. It is undisputed that Dr. Hobbs was not retained for purposes of this litigation, and that his expected testimony is based on his care and services during the treatment of Hernandez, not opinions formed after Hernandez’s discharge from care in anticipation of litigation. Thus, the narrow issue in this special action is whether a treating physician’s testimony concerning the patient’s diagnosis, treatment, and prognosis is “expert testimony” within the meaning of our rules simply because it necessarily draws upon his or her skill, training, and experience as a doctor.
¶ 7 Sanchez argues this case is governed by State ex rel. Montgomery v. Whitten,
¶ 8 We held that “[a] fact witness typically testifies about information he or she has acquired independent of the litigation, the parties, or the attorneys.” Id. at ¶ 14. Thus, a medical fact witness would not be required to perform additional work in order to answer questions other than reviewing his own records. Id. Fact-based testimony is derived from the five senses, i.e., what the treating doctor saw, heard, or felt, and typically is given in response to the “who, what, when, where, and why” questions. Id. at ¶ 15. Questions about experience, training, and the professional’s background and specialization are “relevant to jurors in assessing the credibility of fact witnesses and in determining the weight to give their testimony.” Id. at ¶ 13. In addition, having the doctors “educate” the jurors by explaining terms and procedures in a manner more understandable for the trier of fact does not constitute expert testimony. Id. at 22, ¶ 21,
¶ 9 In contrast, we concluded testimony would constitute expert testimony requiring appropriate compensation if the questions required “a physician to review records or testimony of another health care provider or to opine regarding the standard of care or treatment given by another provider.” Id. at 21, ¶ 16,
¶ 10 Whitten is consistent with Duquette v. Superior Court,
¶ 11 Dr. Hobbs argues that Whitten is not persuasive because it involved a criminal matter requiring a civic duty, pointing out our caution that “[n]othing in this opinion, though, should be read as affecting disclosure obligations or witness compensation issues in civil cases.”
¶ 12 In Whitten, we considered and addressed the issue of treating physician compensation in the criminal context. It is not uncommon for courts to limit the application of them decisions to the issue before them, rather than trying to anticipate the myriad of possible arguments that could be developed or argued in a different application. This
¶ 13 In addition to these cases, many other jurisdictions have reached similar conclusions in civil cases. See, e.g., McDermott v. FedEx Ground Sys., Inc.,
¶ 14 Not all jurisdictions have agreed with this conclusion, however, citing public policy concerns and a physician’s specialized training to support the imposition of a “reasonable fee” requirement for testimony from a treating physician who is not technically an expert witness. See, e.g., Wirtz v. Kan. Farm Bureau Sens., Inc.,
¶ 15 Dr. Hobbs argues that Arizona Rule of Civil Procedure 26(b)(4)(C), which does not apply to criminal eases, is the true governing law regarding this issue and distinguishes civil cases from Whitten. Rule 26(b)(4) provides in pertinent part:
(4) Trial Preparation: Experts.
(A) A party may depose any person who has been identified as an expert whose opinions may be presented at trial.
(B) A party may through interrogatories or by deposition discover facts known or opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for trial and who is not expected to be called as a witness at trial, only as provided in Rule 35(b) or upon a showing of exceptional circumstances____
(C) Unless manifest injustice would result, (i) the court shall require that the party seeking discovery pay the expert a reasonable fee for time spent in responding to discovery under subdivisions (b)(4)(A) and (b)(4)(B) of this rule; and (ii) with respect to discovery obtained under subdivision (b)(4)(B) of this rule the court shall require the party seeking discovery to pay the other party a fair portion of the fees and expenses reasonably incurred by the latter party in obtaining facts and opinions from the expert.
(D) In all cases including medical malpractice cases[,] each side shall presumptively be entitled to only one independent expert on an issue, except upon a showing of good cause____
Dr. Hobbs argues that Rule 26(b)(4) identifies and distinguishes between two types of experts — “one whose opinions may be presented at trial and one who has been retained or specially employed and who is not expected to testify at trial.” He goes on to state that Rule 26(b)(4) requires reasonable payment to an expert “who is responding to the discovery request — whether it is a treating physician who is testifying under Rule 702 and Rule 703, Arizona Rules of Evidence, or an accident reeonstruetionist who is not expected to testify at trial.” However, Rules of Evidence 702 and 703, which apply in both civil and criminal cases and which we necessarily considered in Whitten, deal only with witnesses testifying as experts and not as fact witnesses. Therefore, they do not direct that testifying doctors are necessarily experts; rather, they provide rules applicable to doctors who are engaged as experts.
¶ 17 Rule 26(b)(4)(B) does not apply because Dr. Hobbs was not retained or specially employed in anticipation of litigation or preparation for trial. Moreover, most of his testimony was factual in nature. Having found that neither of these usages of “expert” applies here, we similarly conclude that the mandate of Rule 26(b)(4)(C) to pay the “expert” a reasonable fee also does not apply. The Advisory Committee Notes to Federal Rule of Civil Procedure 26(b)(4) recognize as much, stating, “[an] expert whose information was not acquired in preparation for trial but rather because he was an actor or viewer with respect to transactions or occurrences that are part of the subject matter of this lawsuit ... should be treated as an ordinary witness.” Our holding is harmonious with the Comment to Arizona Rule of Civil Procedure 26(b)(4), which states that the purpose of the Rule is to avoid unnecessary costs and “to make the judicial system in Arizona more efficient, expeditious, and accessible to the people.” Ariz. R. Civ. Proc. 26(b)(4), 1991 comm. & ct. cmts. Requiring parties to pay for the testimony of all treating physicians that are essential to the case but who only testify to the facts would increase the cost of litigation, and in some cases would limit access to the legal system to those most affluent.
¶ 18 Furthermore, we do not think it is appropriate to carve out, for doctors, an exception to the general rule that fact witnesses are not paid for giving testimony. Certainly, treating physicians provide great benefits to society and we do not wish to infringe on their ability to do their important work. However, other professions and trades also provide great benefit to society and have specialized knowledge beyond the lay juror. Courts should not create a special class of fact witnesses who are entitled to expert witness fees while excluding others. We have no basis to weigh the burdens and costs on one profession as opposed to another. We agree with the federal district court of Illinois, which stated:
While physicians certainly have significant overhead costs and a special expertise, so do a myriad of other professions. For instance, should fact witnesses who happen to be engineers, attorneys, accountants or consultants — professions also with special expertise and significant overhead costs— similarly be allowed more than the statutory fee prescribed by § 1821? If the answer is in the affirmative, then does § 1821 merely apply to less prestigious professions? Who decides what professions fall under § 1821 versus the more lucrative “reasonable fee” under [Federal Rule of Civil Procedure] 26(b)(4)(C)? This Court declines to set precedent in this jurisdiction that, essentially, singles out physicians*132 for special treatment. Rather, the more prudent course of action is to follow the unambiguous tenets of [Federal Rule of Civil Procedure] 26(b)(4)(C) and § 1821, which provide that expert witnesses — independent of their profession — obtain compensation at a “reasonable fee”, while fact witnesses — independent of their profession — receive compensation at the statutory fee of $40. If Congress wishes to single out certain professions for higher compensation, that is certainly its prerogative, but this Court declines to enter that arena, which is, essentially, a slippery slope.
Demar v. United States,
¶ 19 Therefore, we hold that Whitten is applicable to physicians in civil litigation. Whether a treating physician is a fact or expert witness depends on the content of the physician’s testimony. When a treating doctor is testifying only to the injury, medical treatment, and other first-hand knowledge not obtained for purposes of litigation, the treating doctor is a fact witness and need not be compensated as an expert. However, where expert testimony is solicited, whether the source of the expert’s underlying information is from personal observation or the observations of others, but the testimony is developed for purposes of litigation, the doctors must be compensated accordingly. Often it will depend on the questions being presented to the treating physician. We lean on the discretionary powers of the trial court to determine when expert testimony is being solicited. We acknowledge that it is impossible to anticipate all scenarios and we are not attempting to do so. Our holding in no way entitles parties to abuse physicians by compelling them to give uncompensated expert testimony. The Guidelines for Inter-professional Relationships in Legal Proceedings was an excellent attempt at compromise, and we encourage similar efforts of cooperation and good faith in the future. See Joint Committee on Interprofessional Relationships et al., Guidelines on Interprofessional Relationships in Legal Proceedings 1992/1993 (1993).
CONCLUSION
¶ 20 Based on the foregoing, we accept special action jurisdiction, grant Sanchez relief and vacate the order compelling expert witness payment to Dr. Hobbs for his testimony relating to the care and treatment of the patient. To the extent Dr. Hobbs’s deposition testimony is expert testimony, he must be compensated accordingly.

. The arbitrator in this matter made a similar ruling on October 19, 2012. It is unclear from the record why both Judge Gama and the arbitrator made rulings.
