Texas Individual Health First Diagnosis or Critical Illness and Specified Disease Checklist is a form used by insurance providers in the state of Texas to determine if a person is eligible for coverage for certain types of medical conditions. The checklist is used to assess the risk of the individual for critical illnesses and specified diseases, such as cancer, Alzheimer’s, heart attack, stroke, and diabetes. It is composed of questions regarding a person’s medical history, lifestyle, and family history. The Texas Individual Health First Diagnosis or Critical Illness and Specified Disease Checklist is divided into two parts. The first part consists of questions about the individual’s general health and lifestyle, including questions about their diet, exercise, alcohol and drug use, and smoking. The second part of the checklist is focused on specific illnesses and conditions, such as cancer, Alzheimer’s, heart attack, stroke, and diabetes. There are three types of Texas Individual Health First Diagnosis or Critical Illness and Specified Disease Checklist: the Standard Checklist, the Enhanced Checklist, and the Comprehensive Checklist. The Standard Checklist is the most basic and is appropriate for those who have a low risk of the conditions mentioned. The Enhanced Checklist is more detailed and is suitable for those with a higher risk of one or more of the specified illnesses and conditions. The Comprehensive Checklist is the most thorough and is recommended for those with a very high risk of the specified illnesses or conditions.
