All policies contain limitations and exclusions. Otherwise premiums would become unaffordable. But the specific limitations and exclusions are likely to differ from policy to policy. Preexisting conditions Insurance companies may require that a period of time pass before the policy pays for care related to a health problem you had when you became insured. Such health problems are called preexisting conditions.
Some companies exclude coverage of preexisting conditions for six months.
If you need long-term care within six months of the policy's issue date for a condition for which treatment was either underway or had been recommended before you took the policy, you may be denied benefits. Specific exclusions Before you buy, be sure you understand exactly what is and is not covered under a particular policy. Some mental and nervous disorders are often not covered. Alcoholism and drug abuse are usually not covered, along with care necessitated by an act of war or an intentionally self-inflicted injury.
