Allow the disabled worker to deduct health insurance premiums paid from income earned except Medicare. If the worker pays for further coverage allow that premium to be deductible, since it is required that everyone carry insurance.
Also allow disabled workers to deduct all dental expenses from earned income if those are reasonable and necessary, such as 2 exams per year and needed care to maintain healthy teeth, especially if they do not have dental coverage. Otherwise poor dental care leads to other health issues, or worsening of current health issues. It does not help in job interviews or appearance on a current job if you have poor dental hygiene
Allow all trips to doctors if related to disabling condition(s) to use mileage as a deductible.
