(a) Neither the execution of a DMOST form under this chapter nor the fact that health care is withheld or withdrawn from a patient in accordance therewith shall, for any purpose, constitute a suicide.
(b) The completion of a DMOST form pursuant to this chapter shall not be deemed or presumed to modify the terms of an existing insurance policy. No policy of insurance shall be legally impaired or invalidated in any manner by the withholding or withdrawal of health care from an insured patient, notwithstanding any term of the policy to the contrary.
(c) No health-care institution, health-care provider, health-care service plan, insurer issuing disability insurance, self-insured employee welfare benefit plan, nonprofit hospital service plan, or any other type of direct or indirect provider of health-care benefits or services, shall require any individual to execute a DMOST form as a condition to being insured, to receiving care, or to being admitted to a health-care institution in order to receiving health-care services.
