Anthem Blue Cross Medigap: Plan Options, Coverage, and Comparison
Medigap, also called Medicare Supplement insurance, fills gaps in Original Medicare by paying some out-of-pocket costs like copays and deductibles. Many insurers sell standardized Medigap plans under letters—each letter stands for a consistent set of benefits. This article explains how plans from a large regional carrier are organized, what common benefits look like, how enrollment and pricing work, and how to compare those options with other companies.
What Medigap covers
Medigap policies pick up expenses that Part A and Part B don’t fully cover. Typical items include hospital coinsurance, skilled nursing facility coinsurance, Part A deductible, Part B excess charges, and some foreign travel emergency care. Coverage is sold in lettered plans standardized by federal rules so a Plan G from one insurer should match Plan G from another in basic benefits. Prescription drugs are not covered by these policies; those are handled through Part D or separate drug plans.
Anthem plan types and benefits by plan letter
The carrier offers several Medigap letters in states where it operates. Not every letter is available everywhere, and federal rules changed which letters new enrollees can buy after 2020. Below is a simplified view of typical letters and the benefits they commonly include. Use this as a starting point, remembering each state filing and the insurer’s policy defines final details.
| Plan letter | Typical benefits covered | Common member trade-off |
|---|---|---|
| A | Basic hospital and medical coinsurance, first three pints of blood | Lower premium, fewer extras |
| G | All Part A and B costs except Part B deductible | Higher premium, broader coverage |
| N | Most Part A and B costs with some copays and no Part B excess charge | Moderate premium, small copays for office and ER visits |
| F (closed to new enrollees) | Comprehensive; covers Part B deductible for eligible enrollees | Highest premium historically; limited availability for new Medicare enrollees |
Eligibility and enrollment periods
Eligibility depends on having Medicare Part A and Part B. The most favorable time to enroll is during the six-month Medigap open enrollment period that starts the month a person is both 65 or older and enrolled in Part B. During that window, insurers generally can’t charge more for preexisting health conditions. Outside that period, underwriting—asking about health history—may apply and rates can be higher. Special enrollment situations can occur when someone moves or loses other coverage, but those vary by state and circumstance.
Premiums, out-of-pocket costs, and pricing factors
Premiums are monthly and differ by plan letter, age, location, tobacco use, and the insurer’s pricing method. Some companies use issue-age pricing that charges based on age at purchase, others use attained-age that rises with age, and some use community-rated pricing that does not vary by age. Besides premiums, members may face copays for specific services depending on the plan letter. Medical underwriting can increase cost for applicants outside guaranteed-issue windows.
State-specific availability and variations
Medigap is federally standardized but state rules and company offerings vary. A plan letter sold in one state might be priced differently or adjusted for state regulations in another. Some states offer additional protections, such as open enrollment extensions for certain life events. Regional insurers sometimes tailor their product mix to local markets; that affects which letters appear on a carrier’s rate filings for a state.
How to compare Anthem plans with other carriers
Start by matching plan letters so you compare like with like. Look at premiums over time, the insurer’s pricing method, and how they handle rate increases. Consider customer service measures like average call wait times and complaint ratios reported to state insurance departments. Also review whether a company offers bundling or discounts that may matter for your household. Remember standardized benefits mean the core coverage is the same, but price and service differ.
Claims handling, customer service, and provider networks
Medigap policies generally allow you to see any doctor who accepts Medicare; there is no separate provider network in most cases. Service quality varies by company. Important practical details include how claims are submitted, how quickly reimbursements are processed, and where to file appeals. State insurance department reports and Medicare’s consumer tools can show complaint histories and customer-service metrics for each carrier.
Documentation and steps to verify coverage
To confirm specifics, review the insurer’s policy brochure, the plan’s certificate of coverage, and the state rate filings for that policy. Compare those documents to official Medicare resources that explain standardized benefits. Ask for written confirmation of premium, covered services by plan letter, and any riders or state-specific adjustments. Keep copies of enrollment forms and policy ID numbers for claims and future verification.

Key takeaways and next steps
Medigap policies fill gaps in Original Medicare with lettered plans that standardize core benefits. For a regional carrier, differences show up in which letters are offered, how premiums are set, and how service is handled. When comparing options, match plan letters, review recent rate history, and confirm state-specific filings and policy language. Keep copies of all documents and consult official Medicare resources and state insurance department information for verification. These steps help clarify coverage trade-offs without relying on sales materials alone.
