This guide is for clinics and billing teams. It explains which Transamerica policies have provider-side eligibility checks, how the portal works, the provider contact details Transamerica lists, how Medicare crossover claims work, and includes a calculator for what a patient owes after Medicare and a supplement plan.
Which Transamerica policy does the patient have?
Transamerica sells several kinds of products, and only some have provider eligibility checks. A traditional life insurance policy pays a death benefit and has no medical benefits to verify. For therapy and other medical visits, the policies you are likely to see are health-related ones. Confirm the product from the member's ID card before you pick a route.
| Product | What it is | How a provider checks it |
|---|---|---|
| Life insurance | Pays a death benefit to a beneficiary | No medical eligibility check. Nothing to bill for a visit |
| Medicare Supplement (Medigap) | Pays some or all of the costs Original Medicare leaves, such as coinsurance. Underwritten by Transamerica Life Insurance Company (Cedar Rapids, IA) or Transamerica Financial Life Insurance (Harrison, NY) | MyMedSuppInfo.com provider portal or Customer Service at 1-800-752-9797 |
| Long-term care | Pays for long-term care services | The Stedi payer directory lists Transamerica Financial Life Insurance Company, Long Term Care (payer ID TFLIC) as supporting 270/271 eligibility checks. Confirm with your clearinghouse |
| Other health or supplemental plans | Employer or individual products | Use the phone number and instructions printed on the member's ID card |

How to verify Transamerica Medicare Supplement eligibility
- Copy the Medicare card and the Transamerica card. You need both, because Medicare is billed first and the supplement picks up after it.
- Confirm the patient has Medicare Part B and is active, using your usual Medicare eligibility check.
- Log in to the provider portal (or register if your practice has no account) and open Eligibility.
- Search the member and record the policy status, effective dates and the plan.
- Check pre-certification requirements in the portal before the first visit.
- Save the result with the date and time. If the portal does not answer your question, call Customer Service at 1-800-752-9797 and write down the representative and reference number.

How a Medicare Supplement plan pays after Medicare
Original Medicare pays first. A Medicare Supplement (Medigap) plan then pays some or all of the costs Medicare leaves to the patient. In 2026, the Medicare Part B annual deductible is $283, per the CMS 2026 Medicare Parts A and B fact sheet, and Medicare Part B typically leaves a 20% coinsurance.
| Plan | Part B coinsurance | Part B deductible | Note |
|---|---|---|---|
| Plan F | Covered | Covered ($283 in 2026) | Only available to people who became eligible for Medicare before 2020 |
| Plan G | Covered | Not covered | Patient pays the Part B deductible |
| Plan N | Covered | Not covered | Copay of up to $20 for some office visits and up to $50 for emergency room visits |
The plan details above are from the Medicare.gov Medigap plan comparison and NerdWallet's Plan F and Plan G comparison. Read the member's plan letter from the policy, since a plan not listed here may pay differently.
Crossover: Most Medigap plans receive Medicare-approved claims automatically through an eligibility-file-based crossover. According to First Coast Service Options crossover guidance, participating providers using claim-based crossover report the group policy number (CMS-1500 Item 9a) and Medigap insurer ID code (Item 9d). Claims for Part A institutional services, claims from non-participating providers and claim-based crossover plans must go directly to the Medigap insurer. On your remittance, look in the TRANSFER TO (COB) field to see whether the claim crossed over, and contact the supplement insurer if it did not.

Common Transamerica eligibility problems
- The patient has a life insurance policy, not health coverage: There is no medical eligibility to verify, so ask for the patient's medical insurance.
- Portal access expired: Registrations inactive for more than 12 months are terminated, so register again as an Administrative User.
- Claim did not cross over: Check the TRANSFER TO (COB) field on the remittance. If it is blank, contact Transamerica at 1-800-854-0186 or send the claim to the Claims Administration address.
- Wrong plan assumed: Read the plan letter from the policy. Plan F, G and N pay the Part B deductible and copays differently.
- Unsure which number to call: Use 1-800-752-9797 for eligibility and general provider questions, per Transamerica's contact page.
