N.M. Stat. § 59A-23A-7
Preexisting condition; definition; coverage.
A. No long-term care insurance policy, certificate or rider, including a group long-
term care policy or certificate shall use a definition of preexisting condition that is more
restrictive than the following: "preexisting condition" means a condition for which
medical advice or treatment was recommended by or received from a provider of health
care services within six months preceding the effective date of coverage of an insured
person.
B. No long-term care insurance policy, certificate or rider, including a group long-
term care policy, certificate or rider, shall exclude coverage for a loss or confinement
which is the result of a preexisting condition unless such loss or confinement begins
within six months following the effective date of coverage of an insured person.
C. The definition of preexisting condition as provided in Subsection A of this section
does not prohibit an insurer from using an application form designed to elicit the
complete health history of an applicant, and, on the basis of the answers on that
application, from underwriting in accordance with that insurer's established underwriting
standards.
D. In the policy, certificate or rider, a preexisting condition, regardless of whether it
is disclosed on the application, need not be covered within six months following the
effective date of coverage of the insured person. No long-term care insurance policy,
certificate or rider may exclude or use waivers or riders of any kind to exclude, limit or
reduce coverage or benefits for specifically named or described preexisting diseases or
physical conditions beyond six months following the effective date of coverage of the
insured person.
