UnitedHealthcare denied prior authorization? Here’s what to do
Summary: UnitedHealthcare prior-auth status is visible in myuhc.com; the peer-to-peer is arranged through the provider line, and many denials are overturned there. A UnitedHealthcare prior-authorization denial can usually be appealed with a letter of medical necessity from your doctor — and an expedited appeal if your health is at risk.
Why UnitedHealthcare denied prior authorization
- The request lacked a letter of medical necessity or clinical notes.
- UnitedHealthcare considers the service experimental or not medically necessary.
- A formulary or step-therapy rule required trying another option first.
- The request used the wrong code or was missing supporting records.
Calling UnitedHealthcare: what to expect
UnitedHealthcare’s line is 1-866-414-1959; member services is typically Mon–Fri, roughly 8am–8pm in your time zone; the number on your ID card may be staffed longer.
To reach a person: enter the member ID from your UnitedHealthcare card, then say "claims" for a denial or "prior authorization" for a pending request, then say "representative" if the automated assistant does not offer a person. Menus change — if yours does not match, say "representative" at any prompt.
Self-service runs through myuhc.com / UnitedHealthcare app (https://www.myuhc.com); the written route is the UnitedHealthcare member appeal (a written request to the appeals address on your EOB; myuhc.com also has an online appeal option for many plans); and you may see these names on your paperwork: myuhc.com, Optum Rx (pharmacy), Optum Behavioral Health.
Step by step: what to do
- Call UnitedHealthcare at 1-866-414-1959 (enter the member ID from your UnitedHealthcare card, then say "claims" for a denial or "prior authorization" for a pending request, then say "representative" if the automated assistant does not offer a person) and get the precise reason for the prior-auth denial.
- Ask your prescriber to submit a letter of medical necessity with clinical notes.
- Request a peer-to-peer review between your doctor and the UnitedHealthcare medical director.
- File a written appeal through the appeal address on your denial letter or the myuhc.com member portal before the 180 days from the date of the denial deadline.
- If your health is at risk, request an expedited (urgent) appeal.
Common mistakes to avoid
- Waiting on the doctor’s office instead of driving the appeal yourself.
- Skipping the peer-to-peer review, which often resolves the denial fastest.
- Not requesting an expedited appeal when the delay could harm your health.
What to say when you call UnitedHealthcare

UnitedHealthcare-specific things to know
- UnitedHealthcare prior-auth status is visible in myuhc.com; the peer-to-peer is arranged through the provider line, and many denials are overturned there.
- Pharmacy prior auths go through Optum Rx, which has its own appeal timeline.
- Pharmacy and behavioral-health decisions come from Optum, which has separate phone lines and appeal addresses — the letterhead tells you which one to call.
- myuhc.com shows claim status and the EOB, and many plans can submit an appeal there directly.
- UnitedHealthcare has a very large Medicare Advantage business; those members follow Medicare appeal rules and use the number on their Medicare plan card.
- Employer plans administered by UnitedHealthcare may be self-funded; the plan document (SPD) then controls what is covered.
Know your rights
You have the right to a written explanation of any denial, to a full copy of your plan documents, and to appeal — first internally, then through an independent external review.
Regulator: your state Department of Insurance (and the federal No Surprises Act). If the internal appeal fails, request an external review and file a complaint with your state Department of Insurance.
If UnitedHealthcare will not move, the escalation paths that carry weight:
- Ask for a second-level review; UnitedHealthcare offers one on most commercial plans.
- Request independent external review through your state or the federal external-review process.
- File with your state Department of Insurance, or the Department of Labor for employer plans.

Frequently asked questions
What is a peer-to-peer review?
It is a call between your treating doctor and a UnitedHealthcare medical director to reconsider the prior-authorization denial. It often resolves denials faster than a written appeal alone.
How fast is an expedited appeal?
When a delay could seriously jeopardize your health, plans must decide an expedited appeal much faster than a standard one — often within 72 hours.
Which UnitedHealthcare number should I call?
The one on the back of your ID card. The general member line, 1-866-414-1959, also works but may transfer you.
Why did my letter come from Optum?
Optum is the UnitedHealth company that handles pharmacy and behavioral-health decisions. Its appeals go to the address on that letter, not the medical appeals address.
Can I appeal on myuhc.com?
Many plans allow an online appeal under the claim detail on myuhc.com. Otherwise, mail a written appeal to the address on your denial letter and keep proof of the date sent.
