For purposes of this article:

(1) "Abortion" means abortion as that term is defined in section two, article two-f of this chapter.

(2) "Attempt to perform or induce an abortion" means an act or an omission of a statutorily required act that, under the circumstances as the person believes them to be, constitutes a substantial step in a course of conduct planned to culminate in the performance or induction of an abortion in this state in violation of the applicable provisions of this code.

(3) "Fertilization" means the fusion of a human spermatozoon with a human ovum.

(4) "Fetus" means the developing young in the uterus, specifically the unborn offspring in the postembryonic period from nine weeks after fertilization until birth.

(5) "Medical emergency" means a condition that, on the basis of a reasonably prudent physician's reasonable medical judgment, so complicates the medical condition of a pregnant female that it necessitates the immediate abortion of her pregnancy without first determining gestational age to avert her death or for which the delay necessary to determine gestational age will create serious risk of substantial and irreversible physical impairment of a major bodily function, not including psychological or emotional conditions. No condition may be deemed a medical emergency if based on a claim or diagnosis that the woman will engage in conduct which she intends to result in her death or in substantial and irreversible physical impairment of a major bodily function.

(6) "Nonmedically viable fetus" means a fetus that contains sufficient lethal fetal anomalies so as to render the fetus medically futile or incompatible with life outside the womb in the reasonable medical judgment of a reasonably prudent physician.

(7) "Pain capable gestational age" means twenty-two weeks since the first day of the woman's last menstrual period. The pain capable gestational age defined herein is generally consistent with the time that is twenty weeks after fertilization.

(8) "Physician" means a person with an unrestricted license to practice allopathic medicine pursuant to article three of chapter thirty of this code or osteopathic medicine pursuant to article fourteen, chapter thirty of this code.

(9) "Probable gestational age of the fetus" means, in reasonable medical judgment and with reasonable probability, the gestational age of the fetus at the time an abortion is planned to be performed.

(10) "Reasonable medical judgment" means a medical judgment that would be made by a reasonably prudent physician, knowledgeable about the case and the treatment possibilities with respect to the medical conditions involved.
