Okla. Stat. tit. 63, § 63-3090.3: Nondiscrimination in treatment

A. A health care provider shall not deny to a patient a life-

preserving health care service the provider provides to other

patients, and the provision of which is directed by the patient or a

person legally authorized to make health care decisions for the

patient:

1. On the basis of a view that treats extending the life of an

elderly, disabled, or terminally ill individual as of lower value

than extending the life of an individual who is younger,

nondisabled, or not terminally ill; or

2. On the basis of disagreement with how the patient or person

legally authorized to make health care decisions for the patient

values the trade-off between extending the length of the patient's

life and the risk of disability.

B. In an action pursuant to this act, if the plaintiff pleads a

prima facie case, the health care provider may defend his or her or

its actions by pleading a legitimate, nondiscriminatory reason or

reasons that provided a basis for the denial of treatment, subject

to an opportunity for the plaintiff to plead that the reason or

reasons for the denial of treatment are discriminatory in their

application.
