This is nоt a typical workers’ compensation case. In a reversal of usual roles, the petitioning employer seeks a holding that its employee’s injury was compensable, while the employee asks that we uphold the decision that she was not entitled to compensation.
This role reversal is due to the exclusivity provision of the Workers’ Compensation Act. 1 The employee would prefer to go forward with her pending Superior Court tort suit against the employer, while the employer prefers to pay compensation, and have its employee’s tort action dismissed.
I.
Petitioner Georgetown University (hospital) seeks review of the decision of the Department of Employment Services (“DOES”) that the injured claimant, Lavern Bentt, M.D., is not entitled to compensation under the District of Columbia Workers’ Compensation Act of 1979(Act), D.C.Code §§ 36-301 et. seq. (1981, as amended) (since recodified at § 32-1501) (2001). The hospital contends that DOES erred in, (1) failing to address the issue of whether the injections administered to Dr. Bentt by her supervising physician at the workplace while she was on the job to reheve her tendinitis brought about what constituted an accidental injury under the Act, (2) in failing to conclude that Dr. Bentt’s initial tendinitis itself was an accidental injury under the Act, and (3) in affirming the hearing examiner’s compensation order even though it failed to find that, even if the tendinitis was not initially caused by an injury at work, it was aggravated by the physical requirements of the job or by the injections administered to her by her supervisor to alleviate it. We agree that the decision of the Director is inadequate as to the first and third issues raised by petitioner, and we therefore reverse аnd remand for further proceedings.
II.
In 1994, claimant Lavern Bentt, M.D., was employed as a fellow at the Georgetown University Hospital. She worked from 8:00 a.m. to 3:00 p.m. or 5:00 p.m. five days a week in the chronic pain clinic. On October 2, 1994, Dr. Bentt experienced some “difficulty” in her left lower ankle when she attended on her own time a banquet while wearing tight shoes. At the beginning of the following work week she “noticed [she] was having a nеw discomfort in her left ankle.... ”
During the ensuing work days, Dr. Bentt’s colleagues and her supervisor, *869 Charles A. Buzzanell, M.D., noticed that she was limping throughout the day and he offered to treat her condition. She declined but, on or about October 6, 1994, when Dr. Buzzanell offered again to administer a nerve block to Dr. Bentt’s left ankle area, she accepted. They went to a treatment room at a time they had agreed upon and, in the presence of the senior resident, Dr. Buzzanell administered the injection. The ankle then, “felt a lot better.” She “thanked him very much, and ... continued on with [her] day.” Although the injection provided temporary relief, the next day the pain returned. At Dr. Bentt’s request, Dr. Buzzanell administered a second nerve block on October 7, 1994, which contained a lower level of steroids. The second nerve block did not reduce the level of pain for long, and after several days Dr. Bentt sought other medical attention. Over a period of time, Dr. Bentt’s pain lessened. However, the skin in the area in which the nerve block injections were administered became ulcerous. Dr. Bentt had to have surgery to cover the ulcerated region.
III.
The administrative agency ruling being reviewed here was precipitated by a medical malpractice lawsuit that was filed by Dr. Bentt against petitioner Georgetown University in the Superior Court of the District of Columbia. Before the matter was tried, the hospital moved for summary judgment on jurisdictional grounds, citing the exclusivity provision of the District of Columbia Workers’ Compensation Act. Mindful of the holding of this court in
Harrington v. Moss,
A claim for workers’ compensаtion was filed in which Dr. Bentt was the claimant. An evidentiary hearing was held before a hearing and appeals examiner. The hearing focused on whether Dr. Bentt sustained an injury which arose out of and in the course of her employment. The hearing examiner issued a compensation order concluding that Dr. Bentt did not sustain “an accidental injury arising out of and in the course of her employment on or about Oсtober 2,1994.”
The hospital filed an application for review with the Office of the Director of the Department of Employment Services seeking a reversal of the hearing examiner’s decision. Dr. Bentt filed a response. The Director issued a decision affirming the hearing examiner’s order denying compensation.
The Director concluded that the hospital’s argument for the application оf this jurisdiction’s aggravation rule was not persuasive. The Director further found that a later fall at work did not aggravate Dr. Bentt’s condition as it injured her knees (rather than her ankle). He also found that substantial evidence supported the hearing examiner’s finding that claimant’s original ankle injury was not work-related and that, therefore, the so-called “dual capacity” doctrine was not triggered and the exclusivity provision of the Act did not apply. The hospital asks that we reverse and remand for further hearing.
IV.
This court’s review of decisions of administrative agencies is limited to de
*870
termining whether the order “is in accordance with law and supported by substantial evidence in the record.”
Joyner v. District of Columbia Dep’t of Employment Servs.,
With respect to whether a claimant sustained an accidental injury arising out of and in the course of her employment, the Act mаndates that it be presumed, in the absence of evidence to the contrary, that a claim comes within the purview of the Act. D.C.Code § 32-1521(1) (2001) (formerly § 36-321(1) (as amended));
Ferreira v. District of Columbia Dep’t of Employment Servs.,
V.
The first stage of the analysis is whether an “initial demоnstration” was made that was sufficient to invoke the Act’s presumption of compensability of the claim. The hearing examiner found that there was sufficient evidence of record to invoke the presumption of compensability, noting that Dr. Bentt’s job required extensive walking and standing and that her condition worsened over the course of her working for employer. The hearing examiner also cited the March 8, 2000, medical report of John B. Cohen, M.D., an orthopedic surgeon, who observed that “claimant’s work activities could easily have caused or aggravated her Achilles tendinitis .... ”
Dr. Bentt (rather than the employer who typically would do so) attempted to overcome the threshold showing of the compensability of her injury, i.e., that it arose out of and in the course of her employment, and to sevеr the presumed causal relationship between her work and her subsequent physical condition. She testified that she had experienced no left foot or ankle pain prior to the October 2, 1994, banquet and that the tight shoes she had worn at the banquet had triggered that “difficulty.” She also presented evidence in the form of two independent medical evaluation reports that indicated not only that her shoes caused her left ankle condition but also that her work played no role in bringing about her original ankle problem. Dr. Bentt cited the report of Richard H. Conant, M.D., an orthopedic surgeon, who stated, “[i]n my opinion, within a reasonable medical probability, her condition did not arise from her normal work activities.” She also relied upon the report of another orthopedist, Major P. Gladden, M.D., whо stated, “I feel that her primary problem initially was the retrocal-caneal bursitis, which was non-work related, most likely related to the wearing of the shoes and the tendinitis was a subsequent complication and the complication resulted from the injection.”
The hospital’s first argument on appeal is that DOES erred in failing to address the issue of whether the injections administered to Dr. Bentt at her work placе while she was on the job caused what constitutes an accidental injury under the Act. There was evidence that she was limping around on the job as she did her rounds and did the other walking that was required in her work in the pain management section. The record offers strong support for the hospital’s position that Dr. Bentt’s supervisor, Dr. Buzzanell, administered the injections to her in order to lessen her discomfort at work and to enable her to be pain free, both as she performed her work and otherwise, and that the administration of the injections arose out of Dr. Bentt’s employment and in the course of her work.
The hearing examiner concluded that “the conditions of claimant’s employment did not play a role in her original left foot
*872
and ankle conditions, which first manifested itself on or about October 2, 1994.” Subsequently, after оbserving that the bulk of the medical evidence focused on the treatment Dr. Bentt received after administration of the nerve block injections by her supervisor the hearing examiner stated: “Having determined that the initial condition was not compensable, this evidence becomes irrelevant.” As we will explain, this view of the relevance of the injections and their results is not sustainable. The hearing examiner also found irrelevant the “dual capacity” doctrine, a conclusion with which we agree.
See Ray v. District of Columbia,
A case from another jurisdiction,
McDaniel v. Sage,
In evaluating whether an injury “arises out of’ employment, this court has adopted the positional-risk standard discussed in
Grayson v. District of Columbia Dep’t of Employment Servs.,
VI.
The hearing examiner’s and Director’s rulings also fail to address adequately the issue of aggravation. It is well established in the District of Columbia that a disability resulting from the aggravation of a pre-existing condition is compensable under the Workers’ Compensation Act.
See
D.C.Code § 32-1508(6)(A) (2001) (formerly § 86-308(6)(A));
Washington Hosp. Ctr. v. District of Cоlumbia Dep’t of Employment Servs.,
In
Clark,
supra,
In this case, the aggravation issue was not discussed by the hearing examiner and mentioned only briefly by the Director. The Director states that the “self-insured Emplоyer’s argument to apply this jurisdiction’s ‘aggravation rule’ is not persuasive.” The Director found that there was no medical evidence in the record showing that Dr. Bentt’s work activities aggravated or contributed to a worsening of her left ankle condition. 2 The Director failed, however to consider whether Dr. Buzzanell’s injections aggravated or complicated an existing injury.
As noted above, Dr. Bentt’s witness, Dr. Gladden, stated that the injections brought about a complication of the tendinitis. *874 This issue of aggravation or complication overlaps the issue of whether Dr. Buzza-nell’s injections brought about an accidental injury under the Act. In addressing the related issues on remand of this case, DOES may, of course, reopen the record.
VII.
Finally we have considered petitioner’s remaining point — that DOES erred in con-' eluding that Dr. Bentt’s initial ankle injury was not itself an accidental injury under the Act — and are not persuaded. The relevant findings are supported by the record. The hearing examiner resolved the controlling issue of credibility in Dr. Bentt’s favor.
Reversed and remanded for further proceedings consistent with this opinion.
Notes
. D.C.Code § 36-304 (1981, as amended) (since recodified at § 32-1504) (2001). A leading treatise explains the reason for the exclusivity provision as follows:
Once a workers' compensation act has become applicable either through compulsion or election, it affords the exclusive remedy for the injury by the employee or the employee’s dependents against the employer and insurance carrier. This is part of the quid pro quo in which the sacrifices and gains of employees and employers are to some extent put in balance, for while the employer assumes a new liability without fault, it is relieved of the prospect of large damage verdicts.
Arthur Larson, et al., Larson’s Workers’ Compensation Law § 100.01 (May 2000) (citations omitted).
. The Director further states that the record contains evidence that the claimant fell at work and hurt her knees, but not her ankle. The Director fails to address the record evidence that Dr. Bentt’s fall tore the "z-plasty” at the site of the ulceration.
