UnitedHealthcare (UHC): Timely Filing, Appeals, and Billing Guide
UnitedHealthcare (UHC) is the largest US commercial and Medicare Advantage payer, part of UnitedHealth Group, insuring roughly 50 million members across commercial, Medicare Advantage, and Medicaid lines. Contracted providers generally have 12 months to file claims, and its standard commercial appeal window is short — 65 days from the denial date — so confirm both in your executed agreement.

What is UnitedHealthcare?
UnitedHealthcare is the insurance arm of UnitedHealth Group and the largest health payer in the country, covering roughly 50 million members. For billers it is really several payers wearing one name: commercial employer and individual plans, UnitedHealthcare Medicare Advantage, UnitedHealthcare Community Plan (Medicaid managed care, contracted state by state), and administrative-services-only (ASO) plans where UHC processes claims but an employer holds the risk.
Optum, also under UnitedHealth Group, handles much of the back-end — behavioral health, claims editing, and the provider portal infrastructure. That is why you will bounce between UHC and Optum logins for a single account.
What are UHC\'s timely filing and appeal deadlines?
Contracted providers generally get 12 months from the date of service to file, but the controlling number is in your agreement — do not assume. The appeal side is where UHC bites: its standard commercial window is commonly 65 calendar days from the denial date, much shorter than most competitors.
| Line | Typical filing | Typical appeal window |
|---|---|---|
| Commercial | 12 months (per contract) | ~65 days from denial |
| Medicare Advantage | 12-month CMS floor | 60 days (CMS) |
| Community Plan (Medicaid) | State-contract specific | State-contract specific |
How do you submit to UnitedHealthcare?
Send electronic claims through your clearinghouse to UHC payer ID 87726 for most commercial plans (verify the ID on the member card — MA and Community Plan use different IDs). Reconsiderations, corrected claims, and appeals go through the UHC Provider Portal, which returns a case number you can track.
Check prior authorization requirements on the portal before scheduling; UHC's advance-notification list changes quarterly, and services that needed no auth last year may need one now.
What billing quirks should you watch?
- The 65-day trap. The single most common way to lose money on UHC is missing the short appeal window while it sat in a work queue.
- Optum hand-offs. Behavioral health and lab claims may adjudicate through Optum with separate policies and IDs, even for a commercial member.
- ASO plans. A UHC card can be a self-funded employer plan; the summary plan description, not UHC policy, governs coverage — read it before appealing a benefit denial.
- Designated Diagnostic Provider. Certain lab and imaging services only pay in-network at DDP-designated facilities, an easy silent denial.
Compare deadlines against Aetna and Cigna, which give far longer appeal windows for the same commercial work.
Frequently asked questions
For contracted providers UHC generally allows 12 months from the date of service, but the exact window lives in your participation agreement and varies by plan and state — commercial, Medicare Advantage, and Medicaid lines each differ. Out-of-network and secondary-payer situations follow separate rules. Always confirm the number in your executed contract before relying on it.
UHC's standard commercial reconsideration and appeal window is unusually short — commonly 65 calendar days from the denial date, far tighter than the 180 days Aetna, BCBS, and Cigna typically allow. Medicare Advantage appeals follow the CMS 60-day floor. Because it is so short, file UHC appeals first when you are working a mixed denial queue.
Electronic claims route through your clearinghouse to UHC payer IDs (commonly 87726 for commercial). Reconsiderations and appeals are submitted through the UHC Provider Portal on UHCprovider.com (the Link/Optum platform), which is the fastest path and gives you a tracking number. Paper appeals go to the address on the remittance advice, which varies by plan.
