My question involves insurance law for the state of: Colorado. My wife began working at a large company (1500 employees) about 7.5 years ago. During the health screening prior to employment she noticed a large sign in the room stating, "No pre-existing conditions allowed". She was not required to complete a pre-existing conditions questionnaire or asked about whether she had these issues. Prior to applying for her position she was diagnosed with Glaucoma. At the time of the screening her Glaucoma was under control and she had not had any procedures for many years. She was seen by her Ophthalmologist twice a year to monitor her pressure. Is there a possibility either the insurance company or her employer can take legal action against her for claims she filed during her employment for Glaucoma-related claims? What is the statute of limitations for a situation like this?
