WINFertility Fertility Billing Guide
WINFertility is one of the oldest specialty fertility benefits management companies in the US, operating since the late 1990s. WIN partners with major commercial insurers — including Cigna, UnitedHealthcare, Aetna, and Anthem — to administer the fertility benefit for employer groups that add it as a carve-out. For billing purposes, WIN acts as a separate payer with its own authorization portal, medical policies, and claim adjudication rules. Patients covered through WIN will have their primary commercial insurance card but fertility benefits must be authorized and billed through WIN. WIN maintains its own contracted network of fertility specialists and embryology laboratories.
Key billing fact: WINFertility (WIN Health Partners) is a fertility benefits manager that works as a carve-out from major commercial insurers. When a patient's Cigna or UHC plan uses WIN, all fertility auth requests and claims route through WIN's system — not the primary payer. Submitting to the wrong entity is the #1 source of avoidable denials.
What WIN Covers for Fertility Treatment
| Service | Coverage | Notes |
|---|---|---|
| IVF (fresh cycle) | ✓ Covered | Covered on most WIN employer plans. Lifetime cycle limits vary by employer (typically 3 fresh cycles). Confirm exact cycle allowance at benefits verification. |
| Frozen embryo transfer (FET) | ✓ Covered | Covered. Some plans count FETs against the cycle limit; others do not. Verify the patient's specific plan rules before billing. |
| IUI (Intrauterine Insemination) | ✓ Covered | Covered with prior auth. Most plans require 3–6 failed IUI cycles before IVF is authorized. Track IUI attempts per patient across all clinics, not just yours. |
| PGT-A / PGT-M | ✗ Not Covered | Generally not covered unless the employer specifically added PGT coverage to the WIN benefit design. PGT-M may be covered with documented genetic indication. Verify before counseling patients. |
| Egg freezing (elective) | ✗ Not Covered | Elective egg freezing is excluded on most WIN employer plans. Medical egg freezing for oncology patients may be covered — document medical necessity explicitly. |
| Donor egg cycle | ✗ Not Covered | Excluded on most standard WIN plans. Some large employers have custom WIN plans that include donor services. Confirm with WIN benefits verification. |
| Diagnostic infertility workup | ✓ Covered | Covered under the fertility benefit. Initial workup including semen analysis, HSG, hormone panels, and ultrasound is included. Bill with specific infertility ICD-10 codes. |
| Ovulation induction medications | ✓ Covered | Covered under pharmacy benefit through the employer's pharmacy manager — not through WIN. Verify which pharmacy benefit applies for injectable fertility medications. |
Prior Authorization Requirements
Submit through WIN's provider portal or by phone to WIN provider services. Include diagnosis codes, AMH/AFC, prior treatment history, and treatment plan. WIN requires documentation of failed conservative treatment (typically 3+ IUI cycles unless contraindicated).
Separate auth required per FET. Include current cycle day, embryo quantity/quality, and transfer date. Auth must be active before the transfer date.
Auth required for each IUI cycle. Submit through WIN portal with infertility diagnosis and semen analysis results for male factor cases.
Included within the IVF authorization. Do not submit separate auth for monitoring ultrasounds — they are covered under the IVF cycle auth.
Requires surgical prior auth separate from the IVF auth. Include azoospermia diagnosis and urologist notes.
Top WIN Fertility Billing Denial Reasons
These are the most common reasons WINFertility denies fertility claims — and how to prevent each one.
How to avoid: When a patient's plan uses WIN as the fertility benefit manager, all fertility claims must go to WIN. Always ask at benefits verification whether fertility is carved out to WIN. Note the WIN payer ID and routing information in the patient's billing record.
How to avoid: Prior auth from Cigna or UHC is not valid for services that WIN administers. Auth must be submitted to and approved by WIN before services are rendered. Calling the member services number on the back of the card will usually reveal whether WIN administers fertility.
How to avoid: WIN requires documentation of prior treatment attempts before approving IVF. Include dates and outcomes of prior IUI cycles, clomiphene/letrozole attempts, and time-to-pregnancy history in the auth package.
How to avoid: Track the patient's running cycle count against their WIN benefit maximum. WIN's portal shows benefit utilization — check before every new cycle start.
How to avoid: WIN requires specific ICD-10 coding: N97.x for female infertility, N46.x for male factor. Secondary codes (PCOS E28.2, diminished ovarian reserve N97.8) strengthen medical necessity. Avoid using Z31.x as the primary diagnosis.
WIN Fertility Billing Tips
Always ask "Is fertility carved out to WIN?"
The single most important question in WIN billing. When a Cigna, UHC, or Aetna patient presents with fertility benefits, call member services and specifically ask whether the fertility benefit is administered by WINFertility. The answer determines where every auth request and claim goes.
Use WIN's provider portal for eligibility verification
WIN has its own provider portal separate from the primary insurer's portal. Register on the WIN provider portal (winfertility.com) to access real-time eligibility, cycle balances, and claim status for all WIN-managed patients.
Get the WIN payer ID for your clearinghouse
Claims to WIN must route through the correct payer ID in your clearinghouse. The WIN payer ID is different from Cigna's or UHC's. Confirm the current payer ID with WIN provider services when you first enroll.
Document conservative treatment thoroughly
WIN medical reviewers look for evidence of prior treatment attempts before approving IVF. A strong auth packet includes dates of IUI cycles, medication trial history, HSG results, and the treating physician's clinical rationale for proceeding to IVF.
Appeal denials with peer-to-peer calls
WIN allows peer-to-peer reviews with their medical directors. This is the fastest path to overturning denials. Request within 14 days of the denial notice for best results.
WINFertility Fertility Billing — Frequently Asked Questions
What is WINFertility and how is it different from my patient's Cigna or UHC plan?
WINFertility (WIN Health Partners) is a fertility benefits management company that administers fertility coverage on behalf of employers. When an employer adds a WIN fertility benefit to their Cigna or UHC plan, WIN takes over all fertility-related functions: eligibility verification, prior authorization, claim adjudication, and appeals. The patient's commercial insurance card (Cigna, UHC) still handles all non-fertility medical claims, but fertility services must go through WIN.
How do I know if my patient has a WIN benefit?
Some patients receive a separate WIN member card; many do not. The most reliable approach: call the primary insurer's member services number and ask specifically whether "fertility benefits are administered by a third-party fertility benefit manager." If yes, ask for the administrator name, phone number, and payer ID. WIN is also identifiable by the WIN Health Partners EOBs patients sometimes bring to appointments.
Can I bill WIN the same way I bill regular insurance?
The billing process is similar — you submit claims via EDI through your clearinghouse — but you must use WIN's specific payer ID and submit to WIN's claim routing address, not the primary insurer. The authorization process also differs: you submit auth requests to WIN directly through their portal or by phone, not through Cigna's or UHC's standard authorization channels.
What happens if I mistakenly bill Cigna instead of WIN for a WIN patient?
Cigna will deny the claim, typically citing "benefits are not covered under this plan for this service" or routing it back to WIN. You will then need to resubmit to WIN. If the timely filing window has passed (WIN typically allows 90 days), the claim may be denied without recourse. This is why identifying WIN carve-out plans during initial benefits verification is critical.
Does WINFertility require prior authorization for every IVF cycle?
Yes. WIN requires prior authorization for all ART services: IVF (fresh and FET), IUI beyond the first attempt, sperm retrieval procedures, and certain add-on services. Auth must be approved before services are rendered — retroactive authorization is not available. Submit auth requests at least 5 business days before the anticipated cycle start date.
Other Payer Guides
UHC requires prior authorization for virtually all ART procedures. Uses Optum as its fertility benefit manager on many employer plans.
Anthem operates as the BCBS licensee in 14 states. Uses AIM Specialty Health (an Anthem subsidiary) for prior authorization in many markets.
Cigna uses LifeSource (a Cigna subsidiary) as its specialty fertility benefit manager on many plans. Fertility coverage is highly variable by employer plan.
Aetna has one of the clearest published fertility medical policies in the industry. Aetna owns CVS Caremark, which manages pharmacy benefits including fertility medications.
BCBS has 36 independent state licensees — each with its own fertility coverage policies and prior auth processes. The BlueCard program adds complexity when patients are treated out of their home state.
Progyny uses a Smart Cycle model that bundles all IVF services into pre-authorized treatment units. Claims must map exactly to the approved Smart Cycle components or they will be denied — this is fundamentally different from fee-for-service billing.
Humana provides limited fertility coverage on most commercial plans. Fertility benefits are primarily available on fully-insured employer plans in mandate states. Medicare Advantage plans (Humana's largest business) do not cover fertility treatments.
