What happens if I rely only on VA coverage and skip Part B?

The VA and Medicare are completely separate systems. The VA covers care it provides at its own facilities for conditions it determines are related to your service. It does not coordinate with Medicare, and Medicare does not pay for care you receive at a VA facility.If something happens outside the VA system, like an emergency at a non-VA hospital or a specialist referral to a community provider, you could be left without coverage unless you have Medicare. Some veterans assume the VA will cover everything. In practice, there are gaps, access issues, and situations where you simply need care outside the VA.The penalty risk is real. If you delay enrolling in Part B past your Initial Enrollment Period and later decide you want it, you'll likely pay a 10 percent premium surcharge for every 12-month period you were eligible but didn't enroll. That penalty is permanent and adds up over time.There are situations where veterans have other qualifying coverage, like employer insurance, that allows them to delay Part B without penalty. But VA coverage alone does not count as creditable coverage for Part B purposes under Medicare rules.This is a decision worth talking through carefully, ideally with a VA benefits counselor and a Medicare counselor, before you miss your enrollment window.
