52 Pa. Code § 56.111
A public utility may not terminate service, or refuse to restore service, to a premises when a licensed physician, physician assistant, or nurse practitioner has certified that the customer or an applicant seeking restoration of service under § 56.191 (relating to payment and timing) or a member of the customer's or applicant's household is seriously ill or afflicted with a medical condition that will be aggravated by cessation of service. The customer shall obtain a letter from a licensed physician, physician assistant or nurse practitioner verifying the condition and promptly forward it to the public utility. The determination of whether a medical condition qualifies for the purposes of this section resides entirely with the physician, nurse practitioner, or physician assistant and not with the public utility. A public utility may not impose any qualification standards for medical certificates other than those specified in this section.
