N.D. Cent. Code § 23-06.5-10

A health care provider, long-term care services provider, health care service plan, insurer issuing disability insurance, self-insured employee welfare benefit plan, or nonprofit hospital service plan may not charge a person a different rate or require any person to execute a health care directive as a condition of admission to a hospital or long-term care facility nor as a condition of being insured for, or receiving, health care or long-term care services. Health care or long-term care services may not be refused because a person has executed a health care directive.
