WPS (TFL Claims Contractor)
Wisconsin Physicians Service — the Defense Health Agency contractor that processes TRICARE For Life secondary claims.
Also known as: Wisconsin Physicians Service, TFL contractor, WPS-TFL
Quick answer
Wisconsin Physicians Service (WPS) is the DHA contractor that administers TFL claims under the TRICARE Dual Eligible Fiscal Intermediary Contract. After Medicare processes a claim, it electronically crosses over to WPS, which calculates the TFL secondary payment under TRICARE rules and sends an Explanation of Benefits.
Why it matters
If you ever need to ask about a TFL payment, dispute a denial, file an overseas claim, or check claim status, WPS is who you call: 1-866-773-0404 (stateside).
Why this matters at age 65
Once you transition from a TRICARE regional contractor (e.g. Humana Military, Health Net) to TFL, WPS becomes your single TRICARE claims point of contact. Save 1-866-773-0404 in your phone before your 65th birthday so you're not searching for it during a billing question.
When you'll encounter it
On TFL Explanation of Benefits (EOBs), provider billing questions, claim disputes, overseas claims, and appeals.
Impact on Medicare
None — WPS handles only the TRICARE secondary side.
Impact on TRICARE For Life
WPS is the operational engine of TFL claim processing for stateside care.
Military-specific context
WPS-TFL is separate from the prior TRICARE regional contractors that handle Prime/Select for under-65 retirees. Their authority extends only to TFL secondary claims.
Common misconceptions
- "I have to file TFL claims myself." — No. Claims auto-crossover from Medicare to WPS in most cases. Only file manually for overseas care or non-crossover providers.
- "WPS can change my Medicare payment." — WPS can only adjust the TFL secondary portion. Medicare adjustments must be requested through Medicare.
Common mistakes to avoid
- Calling WPS for a Medicare-side billing problem — call 1-800-MEDICARE for that.
- Not waiting the full crossover window (typically 30 days) before assuming a claim was lost.
- Paying a provider before checking the TFL EOB to see what TFL actually paid.
Real-world scenario: A retired Navy chief receives a hospital bill for a $1,250 deductible that he believes TFL should have covered.
He calls WPS at 1-866-773-0404. The rep confirms Medicare paid 80% but the crossover failed because the hospital's TRICARE ID number was missing. WPS reprocesses the claim, TFL pays the deductible, and the hospital reverses the patient balance.
Questions people commonly ask

- Provider AcceptanceWhether a specific provider agrees to bill Medicare and/or TFL — and under what terms.
- Who pays first, Medicare or TRICARE For Life?Medicare pays first for any service it covers. TFL pays second. The claim usually crosses over automatically — you should never pay out of pocket up front.
- Is there an enrollment fee for TRICARE For Life?No. TFL has no enrollment fee and no monthly premium. The only premium you pay is for Medicare Part B.
- What does TRICARE For Life actually cover?TFL is a wraparound. For services Medicare and TFL both cover, TFL pays nearly all remaining cost-shares. For Medicare-only services, TFL still acts as secondary. For TFL-only services (very few), TFL pays as primary.
- Do I have to file claims myself?Almost never. Medicare and TFL claims cross over automatically. The exceptions are non-network pharmacy, overseas care, and providers who opt out of Medicare.
- Does TFL cover long-term care or a nursing home?No. Medicare and TFL only cover short-term skilled care after a qualifying hospital stay. Custodial long-term care (assisted living, nursing home for daily living help) isn't covered by either.
