What CHAMPVA covers for internal medicine

Internal medicine visits are covered outpatient care: the $50 yearly deductible, then 25 percent of the allowable amount, with the family's yearly costs capped at $3,000. Diagnostic tests an internist orders are covered without prior approval when medically necessary. If you also have Medicare, CHAMPVA pays second and you will normally have no cost share at all.

Before you call a Illinois office: Internists who see Medicare patients are the strongest CHAMPVA candidates in the directory. Confirm with billing, not the front desk.

The rules above are federal, so they read the same in Illinois as anywhere else. Our internal medicine doctors page has the full detail including anything that needs advance approval.
