Section 2005
Section 2005.30 The Minimum
Definition of Pre-existing Illness or Pre-existing Condition
a) A "pre-existing illness" or "pre-existing
condition" as constructed by the definition of sickness and the provisions
for Time Limit on Certain Defenses in an accident and health insurance policy
issued after the effective date of this Part shall mean any disease, illness,
sickness, malady or condition which was:
1) diagnosed or treated by a legally qualified physician prior to
the effective date of coverage for the insured with consultation, advice or
treatment by a legally qualified physician occurring within 24 months prior to
the effective date of coverage for the insured; or
2) diagnosed or treated by a legally qualified physician prior to
the effective date of coverage for the insured, but a legally qualified
physician demonstrates that there is a reasonable medical question that the
disease, illness, sickness, malady or condition involved did continue within 24
months prior to the effective date of coverage for the insured without the
necessity of consultation, advice or treatment by a legally qualified
physician; or
3) evident because there was a clear, distinct symptom or
symptoms of the disease, illness, sickness, malady or condition demonstrable
prior to the effective date of coverage for the insured with the occurrence of
such symptoms being evident within 12 months prior to the effective date of
coverage for the insured and in which, in the opinion of a legally qualified
physician, would;
A) indicate that the diseases, illness, sickness, malady or
condition probably began and manifested itself before the effective date of the
coverage for the insured, and
B) would cause an ordinarily prudent person to seek diagnosis,
care or treatment.
b) The above definition is the minimum required. Any definition
more favorable to the insured may be used. The time limitations in this
Section do not apply to the company's underwriting standards such as the
investigation of an applicant's health history.
