How to appeal an Optum Behavioral Health denial
Behavioral health under a UnitedHealthcare plan is often administered by Optum — a separate operation with its own submission route, and sending the appeal to the wrong one wastes the window.
Deadlines
These are the windows Optum Behavioral Health publishes. They vary by contract, product line and state — so treat the date on your remittance advice as the one that governs.
- First-level appeal
- commonly 90–180 days for commercial contracts
- Medicaid and federal contracts run on different clocks — some as long as a year, set by state rule. The denial letter carries the controlling deadline.

The appeal path
- 01
Confirm who actually administers the benefit
The remittance and denial letter name the entity. Behavioral health carved out to Optum does not go through the medical plan's appeals unit.
- 02
First-level appeal
Follow the submission method and deadline printed on the Explanation of Payment or denial letter — those control.
- 03
Second-level or external review
Availability depends on the underlying plan, the state, and whether the benefit is commercial, Medicaid, or federal.
Where to submit
- The method named on the Explanation of Payment or denial letter — this is the authoritative instruction
- The Optum provider portal for the applicable plan
- The appeals address printed on the denial, which may differ from the claims address
What to include
- The Explanation of Payment showing the denial
- Clinical documentation supporting medical necessity and level of care
- The treatment plan and progress notes for the period in dispute
- The specific coverage criteria the denial cites, where it names one
What catches practices out
- Carve-out routing is the recurring failure. An appeal sent to the health plan instead of the behavioral health administrator can sit unrouted until the window closes.
- Level-of-care denials turn on documented criteria, not clinical conviction. Argue against the criteria the denial actually cites.
- Deadlines differ across commercial, Medicaid, and federal contracts on the same administrator — never reuse a deadline from a different line of business.

Common questions
- Why did my behavioral health claim go to Optum instead of UnitedHealthcare?
- Because many plans carve the behavioral health benefit out to a separate administrator. The medical plan and the behavioral health administrator have different claims and appeals operations, and an appeal filed with the wrong one does not get forwarded reliably.
- How long do I have to appeal?
- It depends on the contract behind the member's benefit — commercial windows commonly fall in the 90-to-180-day range, while Medicaid and federal contracts follow their own rules. The deadline printed on the denial letter is the one that governs.
- What wins a level-of-care appeal?
- Documentation mapped to the specific criteria the denial cites. Progress notes and a treatment plan that address each criterion do far more than a clinician's assertion that the level of care was appropriate.
