Final answer:
Medicare refusing to cover a claim (option 4) is not a good reason to purchase a long term care policy, as that refusal may be related to Medicare's known coverage gaps, such as prescription drugs, rather than a need for long term care.
Step-by-step explanation:
The question concerns the decision-making process behind purchasing a long term care policy. An example of a reason that is not good for purchasing such a policy is because Medicare refused to cover a claim. Medicare's refusal to cover a single claim doesn't necessarily justify the purchase of a long term care policy, particularly if the refusal is due to the claim falling into one of Medicare's coverage gaps, such as prescription drugs, which is a well-known limitation of the program.
On the other hand, Medicaid covers certain groups mandated by federal law, such as the blind, disabled, and children under the Children's Health Insurance Program whose family income is below the poverty level. However, since states have significant latitude in setting their eligibility standards for Medicaid, what might make one eligible in one state, may not in another. This variability does not inherently justify the purchase of a long term care policy either.
It is also not a good reason to purchase a long term care policy simply because deafness runs in a family or because one does not qualify for Medicaid; these scenarios do not directly correlate with the need for long term care insurance, which is typically designed to cover the costs of long term care services, such as nursing home care, not necessarily inherited conditions or general medical coverage.
