Chapter 8: How to Enroll and Get the Most Benefits

Enrollment is not one-size-fits-all for veterans. Start by identifying which coverage you have, mark your Medicare deadlines, and confirm whether current-employment coverage gives you a Special Enrollment Period. VA health care does not require Medicare, but VA encourages eligible veterans to sign up; Medicare and VA remain separate programs with their own rules.^[1][2]

Chapter 7: The Costliest Mistakes Veterans Make · Field guide contents · Chapter 9: Maximizing Your Medicare Investment

1. Prepare before you enroll

Before you apply, gather the information that will help you answer enrollment questions and compare coverage. Keep your Social Security account information, Medicare or enrollment letters, VA or TRICARE identification, prescription list, preferred doctors, and details about any current employer coverage in one place. If your income may affect Medicare premiums, keep recent tax and income records for questions about higher-income adjustments.^[10]

• Social Security account information or a plan for contacting Social Security
• Current VA, TRICARE, or CHAMPVA information, as applicable
• Details about current-employment group health coverage, including the employer and coverage end date
• A current prescription list and preferred doctors or facilities
• Recent tax and income records if you may have an income-related Medicare premium adjustment^[10]

The Part B coverage question

The key question is not simply whether you have insurance. Ask whether you are covered by a group health plan through your or your spouse's current employment. That is the type of coverage that can support the usual Part B Special Enrollment Period. VA health care, COBRA, and retiree coverage are not the same as current-employment coverage for this purpose.^[2][1]

Part D is a separate decision

VA and TRICARE prescription coverage are generally considered creditable for Part D. You can usually delay Part D while that creditable drug coverage continues, but keep the coverage notice and revisit the decision when coverage ends. Part D may still be useful if you want prescriptions from local pharmacies or non-VA providers; compare drugs, pharmacies, premiums, and cost sharing.^[4][1]

2. Mark your Medicare enrollment windows

Initial Enrollment Period: your first window

The Initial Enrollment Period is a seven-month window: the three months before the month you turn 65, your birthday month, and the three months after. If you enroll before your birthday month, Part B can generally begin in your birthday month; later enrollment can mean a later start date.^[2]

• Three months before your 65th-birthday month
• The month you turn 65
• Three months after your 65th-birthday month
• Check your actual start date with Medicare because timing differs depending on when you apply and whether you are automatically enrolled^[2]

Special Enrollment Period: current-employment coverage

A qualifying SEP may be available while you or your spouse are actively working and covered by a current-employment group health plan. After the employment or coverage ends, the usual SEP window is eight months. COBRA and retiree coverage do not create the usual job-based SEP, so check with Social Security before you rely on one.^[2][3]

Annual Election Period: October 15 through December 7

Each year from October 15 through December 7, people with Medicare can make permitted changes to Medicare Advantage or Part D coverage, or move between Original Medicare and Medicare Advantage. Changes generally take effect January 1. Compare the new plan's network, drugs, premiums, deductibles, copayments, and authorization rules before making a change.^[11][9]

Medicare Advantage Open Enrollment: January 1 through March 31

The Medicare Advantage Open Enrollment Period is for people already enrolled in Medicare Advantage. During this period, you can generally switch to another Medicare Advantage plan or return to Original Medicare and join a Part D plan. The change generally begins the first day of the following month.^[11]

General Enrollment Period: January 1 through March 31

If you missed your Initial Enrollment Period and do not qualify for an SEP, the General Enrollment Period is the annual opportunity to sign up for Part A and Part B. A late-enrollment penalty may apply, and coverage does not begin immediately, so use this as a reminder to verify your status rather than waiting for the deadline.^[2][3]

3. Enroll in Medicare Parts A and B

First, check whether enrollment is automatic

If you started Social Security or Railroad Retirement benefits at least four months before turning 65, Medicare says you will generally be enrolled automatically in Parts A and B. Review the card and premium information when it arrives. If you are not automatically enrolled, contact Social Security to apply.^[12]

1. Confirm your timing Write down your Initial Enrollment Period and determine whether a current-employment SEP applies. Do not treat VA, COBRA, or retiree coverage as a job-based SEP without confirmation.^[2][1]
2. Apply through Social Security Use the Medicare-only enrollment route at Social Security, or call 1-800-772-1213 if you need help. Keep the confirmation and review the effective dates.^[12]
3. Keep paying attention to Part B billing The standard Part B premium is $202.90 per month for 2026, although some people pay more because of income or penalties. Most beneficiaries have the premium deducted from Social Security; others receive a Medicare bill.^[9][13]
4. Recheck your military coverage Once Medicare is active, confirm how your VA, TRICARE, or other coverage is used. Medicare and VA do not pay for the same item or service, and you generally choose which program to use for each visit.^[14][1]

For TRICARE For Life beneficiaries

TRICARE For Life requires both Medicare Part A and Part B. Part C and Part D are not required for TFL. When Medicare and TRICARE both cover a service, Medicare generally pays first and TFL pays last. TFL beneficiaries must keep paying the Part B premium to keep this coverage.^[5][6]

For veterans using VA health care

Having Medicare does not by itself cancel VA health care eligibility. At each visit, understand which program you are using: VA pays for VA-authorized care, while Medicare pays for Medicare-covered care under its own rules. Non-VA community care generally must be authorized by VA before you receive it.^[1][15][14]

4. Compare Medicare options after Parts A and B

After Parts A and B are in place, you can compare Original Medicare, Medicare Advantage, and—when appropriate—Part D or supplemental coverage. Medicare Advantage plans have their own networks, referrals, prior authorization, deductibles, copayments, and yearly out-of-pocket limits. Those plan rules apply to the Medicare-covered care the plan handles; they do not replace VA authorization rules.^[11][9][1]

KFF reported that 32% of individual Medicare Advantage plans offered some Part B premium reduction in 2026; many plans did not, and availability varies by plan and location. A $0 plan premium is not the same as $0 health care: you still generally pay Part B, and plan cost sharing and rules apply.^[8][7][9]

• Confirm that your doctors, hospitals, and pharmacies participate in the plan's network
• Check covered drugs, formularies, pharmacy rules, and any Part D premium
• Review deductibles, copayments, prior authorization, referrals, and the annual out-of-pocket limit
• Ask how the plan works with your VA or TRICARE use and travel pattern
• Read the plan materials and Evidence of Coverage; VAF does not offer every plan available in your area

A special review for TRICARE For Life

If a TFL beneficiary chooses Medicare Advantage, nonemergency care generally must come through the plan's network. Copayments may be due at the time of service, and paper claims to TRICARE may be needed for reimbursement. Review the plan and TRICARE rules before changing from Original Medicare.^[5]

A special review for VA care and emergencies

For non-VA emergency care, call 911. VA guidance includes using an emergency department and notifying VA within 72 hours, along with other eligibility and authorization requirements. Urgent care is not automatically treated as emergency-department care under those rules.^[17]

5. A veteran-focused enrollment review

A useful review starts with your actual benefits picture rather than a generic recommendation. It should identify your VA enrollment and care patterns, TRICARE or CHAMPVA status, current-employment coverage, preferred providers, prescriptions, travel, and any income-related premium questions. It should then compare the total plan rules and costs for your county.

1. Map your coverage Separate VA health care, TRICARE For Life, CHAMPVA, employer coverage, retiree coverage, and COBRA. These programs have different enrollment and coordination rules.^[5][1][2]
2. Check the network and drugs Verify the providers you use, the pharmacies you prefer, and the prescriptions you take. A plan that looks attractive on one feature may not fit your care pattern.^[11][9]
3. Review the full cost picture Include Part B, plan premiums, deductibles, copayments, drug costs, and the yearly out-of-pocket limit. Treat any Part B premium reduction as one plan feature, not the whole comparison.^[9][7]
4. Confirm before changing Ask Medicare, VA, TRICARE, or the plan how the proposed choice affects your specific coverage. Keep written confirmation of enrollment dates and any authorization or claims instructions.
