876 F.2d 857
10th Cir.
1989
McKAY, Circuit Judge.

In this mаlpractice diversity case, plaintiff appeals the district court’s order allowing substitution of the parties of the United States for defendant Dr. Paul Fieldstone. The United States is the proper party defendant in “any civil action or proceeding brought in any court against any employee of the government or his estate for ... damage or injury.” 28 U.S.C. § 2679(c) (1982), Tort Claims Procedure, Exclusiveness of Remedy. The propriety of the trial court’s substitution turns on whether Dr. Fieldstone was a government employee or an independent contractor when hе performed Private Lilly’s surgery. After substitution, the trial court dismissed the complaint based upon Feres v. United States, 340 U.S. 135, 71 S.Ct. 153, 95 L.Ed. 152 (1950). 1 We reverse the district court’s order allowing substitution of the parties and remand for trial on the рlaintiff’s malpractice claim.

While a patient at Irwin Army Hospital, Private Dean Lilly needed emergency urological surgery. Because the staff urologist was absent, the hospital called Dr. Fieldstone, a civilian consultant on call at the request of the regular Army urologist, to perform the plaintiff’s emergency surgery. Private Lilly sued Dr. Fieldstone for medical malрractice arising out of that surgery.

There is no factual dispute in this case. We review questions of law de novo. In re Ruti-Sweetwater, Inc., 836 F.2d 1263, 1266 (10th Cir.1988). The standard of review on appeal is the same ‍‌​​‌‌​‌​‌​​‌‌​‌‌‌‌‌‌​​​​​​​​‌​‌‌‌​‌​‌‌‌​‌‌‌​​‌‌‌‍standard applied by the trial court in making its initial ruling. Boise City Farmers Coop. v. Palmer, 780 F.2d 860, 866 (10th Cir.1985).

The critical determination in distinguishing a federal employee from an independent contractor is the power of the federal government “to contrоl the detailed physical performance of the contractor.” Logue v. United States, 412 U.S. 521, 528, 93 S.Ct. 2215, 2219, 37 L.Ed.2d 121 (1973). In our circuit “the key inquiry under this control test is whether the Government supervises the day-to-day operations of the individual.” Lurch v. United States, 719 F.2d 333, 337 (10th Cir.1983).

In Lurch, a case similar to the one before us, the plaintiff sued the Veterans Administration hospital under the Federal Tort Claims Act alleging that a surgeon’s negligence caused his hearing loss. In dicta, we noted that

Because a physician must exercise his own professional judgment, no one controls the detailed physical performance of his duties. Givеn this, by strictly following the traditional control test it is doubtful whether a physician could ever be found to be a federal employee under the FTCA.

719 F.2d at 337. Although the application of a “modifiеd control” test “seems ‍‌​​‌‌​‌​‌​​‌‌​‌‌‌‌‌‌​​​​​​​​‌​‌‌‌​‌​‌‌‌​‌‌‌​​‌‌‌‍logical” in this situation, we did not adopt such a test in Lurch because the issue was not before us. Id. at 337-38. But see Quilico v. Kaplan, 749 F.2d 480, 484-85 (7th Cir.1984) (holding strict control test inapplicable in determining the scope of immunity for physicians under federal law because medical ethics require physicians to exercise independent judgment in the best interest of their patients).

While the defendant urges us to adopt Quilico’s “modified contrоl” test, we do not find that label helpful. It is uncontroverted that a physician must have discretion to care for a patient and may not surrender control over certain medicаl details. Therefore, the “control” test is subject to a doctor’s medical and ethical obligations. Whether we label the test “control” or “modified control” is not determinativе. What we must do in the case of professionals is determine whether other evidence manifests an intent to make the professional an employee subject to other fоrms of control which are permissible. A myriad of doctors become employees by agreement without surrendering their professional responsibilities. The United States is equally cаpable of making such an arrangement by express, unambiguous agreement. Our conclusion in this case is that it simply has failed on this record to demonstrate that that was the nature of its аgreement with Dr. Fieldstone.

We now address the facts and analysis which have led us to our judgment. The plaintiff contends that Dr. Fieldstone was an independent contractor when he performed this surgery because the hospital had hired Dr. Fieldstone as a consultant in urology. Although the defendant was a member of the Army Reserve, he was not fulfilling that obligation at Irwin Army Hospital at the time the events at issue occurred. Plaintiff argues that defendant was acting solely in his role as consultant (i.e., independent contractor) when he performed the surgery.

The trial court analyzed this case under Norton v. Murphy, 661 F.2d 882 (10th Cir.1981). The factors considered by the Norton court and applied by the trial court in this case are: (1) the intent of the parties; (2) whether the United States controls only the end result or may also control the manner and method of reaching the result; (3) whether the person uses her own equipment or that of the United States; (4) who provides liability insurance; (5) who pays social security tax; (6) whether federal regulations prohibit federal employees from performing such contracts; and (7) whether the individual has authority to subcontract to others. Id. at 884-85.

The trial court based its “control” determination ‍‌​​‌‌​‌​‌​​‌‌​‌‌‌‌‌‌​​​​​​​​‌​‌‌‌​‌​‌‌‌​‌‌‌​​‌‌‌‍on the first factor in Norton, the intent of the parties, gleaning the parties’ intent almost solely from a Provider and Pledge Agreement signed by Dr. Field-stone. 2 We are unpersuaded that this agreement adds anything which illuminates the intent of the parties on the issue of whether Dr. Fieldstone was an employee or a private contractor. The last eighteen words of the quoted portion are, at best, ambiguous. The by-laws are not an exhibit to the record and there is no testimony regarding them. In any event, it is not clear who is being released — the government or Dr. Fieldstone. Becаuse the language of the agreement is so ambiguous, we accord the agreement no weight in our “control” determination.

Under our review of all of the factors in this case, we find that Dr. Fieldstone is an independent contractor. Although Dr. Fieldstone argues that the Provider and Pledge Agreement explicitly guaranteed him immunity from civil liability and that he specifically rеlied on its language and his personal knowledge that military doctors are immune from civil liability when he agreed to substitute for a military specialist in an emergency, we believe that fаctors raised by the plaintiff and the defendant’s own admissions more clearly manifest the parties’ intent. Dr. Fieldstone did not have an arrangement with the hospital whereby he was always rеquired to see patients there. For instance, Dr. Fieldstone could refuse to treat a military patient if he wanted to, and in fact in this case he initially requested that the Army send Private Lilly to another hospital for treatment. Although the Army denied his request and Dr. Fieldstone performed Private Lilly’s surgery ‍‌​​‌‌​‌​‌​​‌‌​‌‌‌‌‌‌​​​​​​​​‌​‌‌‌​‌​‌‌‌​‌‌‌​​‌‌‌‍at Irwin Army Hospital, he certainly was not required to do so. In other instances he wаs free to see patients at his private office. (Plaintiff’s Brief, citing Col. Alexander’s Depo., at 45, lines 8-22.)

In addition, Dr. Fieldstone billed the Army separately at his standard specialty fee rates. He did not reduce his fees because he served as a National Guardsman or as a civilian consultant to the military. He maintained a private off-base office, and hаd exclusive control over his patients and records. The Army also did not furnish Dr. Fieldstone with permanent and private office space or secretarial help at the hosрital. He only occasionally used a temporary office when he dictated his operative reports. Dr. Fieldstone did not work under a written contract with the government, and wаs never regularly scheduled on the hospital duty roster. Nor did he maintain regular or prescribed office hours as a civilian consultant.

We find that the Army controlled little about the end result or the manner and method of reaching a result. Clearly, the end result (ie. the outcome of surgery) was beyond the Army’s control. Although Dr. Fieldstone contends he was subject to the same rules, rеgulations and hospital control as other military physicians, and that he had limited contact and no control over military patients he treated in emergencies after his work wаs completed, nothing in the record suggests that this relationship was any different than it would be for a doctor in a private hospital with staff privileges. From the record it appeаrs that he retained all the control over the choices he made, that he would have had in a private hospital. Surely, being subject to hospital’s rules as a condition of staff privileges does not remotely make a private physician an employee of that hospital.

We agree with the trial court that the “control” determination is difficult to make; but, on balance, viewing these factors as a whole, we cannot agree that the government “controlled” ‍‌​​‌‌​‌​‌​​‌‌​‌‌‌‌‌‌​​​​​​​​‌​‌‌‌​‌​‌‌‌​‌‌‌​​‌‌‌‍Dr. Fieldstone enough to render him a government employee. Wе cannot fairly say that the government “supervise[d] the day-to-day operations” of Dr. Fieldstone. Lurch, 719 F.2d at 337. Because we conclude on the record before us that Dr. Fieldstone is an indеpendent contractor, we reverse the trial court’s order substituting parties and remand for further proceedings consistent with this opinion.

REVERSED and REMANDED.
