OptumRx denied your claim: how to appeal
OptumRx is UnitedHealth Group's pharmacy benefit manager and administers drug coverage for UHC commercial and Medicare Part D plans, plus many third-party employer groups. The appeal track mirrors UHC procedurally but is filed and decided separately from the medical benefit.
If OptumRx denied a claim or service, you can appeal, and the plan must give you its file and the criteria it used. Filing windows by plan type: at least 180 days (employer self-funded plans); at least 180 days (insured and Marketplace plans); 65 days from the notice (Part D); 60 days from the notice (Medicaid managed care). The date printed on your denial notice controls; it can only be later than these floors, never earlier.
OptumRx appeals: the rule, the deadline and the next level, by plan type
OptumRx adjudicates the pharmacy benefit for a plan sponsor, so the sponsor's rules govern the appeal: an employer plan (ERISA), an insured or Marketplace plan, Medicare Part D or Medicaid. The denial letter names the plan whose rules apply.
| Plan type | Rule that governs | File your appeal within | The plan must answer | If the plan says no again |
|---|---|---|---|---|
| Employer self-funded plan (ERISA) Most large employers. The employer pays the claims and hires the carrier to administer them; the Summary Plan Description says self-funded or self-insured. | ERISA § 503 (29 U.S.C. § 1133) and the claims-procedure rule, 29 CFR 2560.503-1. Federal external review under 45 CFR 147.136(d) for non-grandfathered plans. | At least 180 days from the adverse benefit determination (29 CFR 2560.503-1(h)(3)(i)). | Urgent care: 72 hours. Pre-service: 30 days. Post-service: 60 days (29 CFR 2560.503-1(i)(2)). | Federal external review by an accredited independent review organization, requested within 4 months of the final internal denial (45 CFR 147.136(d)); then a civil action under ERISA § 502(a). State insurance departments do not regulate self-funded plans; the U.S. Department of Labor does. |
| Fully insured employer, individual or Marketplace plan The carrier holds the risk and is licensed in your state. Small employers and almost all individual and HealthCare.gov plans. | 45 CFR 147.136 (Public Health Service Act § 2719), which applies the 29 CFR 2560.503-1 procedures and adds state external review; state insurance law on top. | At least 180 days from the denial (45 CFR 147.136(b); 29 CFR 2560.503-1(h)(3)(i)). | Urgent care: 72 hours. Pre-service: 30 days. Post-service: 60 days. Prior-authorization decisions by Marketplace issuers from 2026: 72 hours expedited, 7 calendar days standard (CMS-0057-F). | External review through your state's process, or the federal process where the state has none, generally within 4 months of the final internal denial (45 CFR 147.136(c), (d)). The state insurance department and its Consumer Assistance Program take complaints. |
| Medicare Part D (drug plan or MA-PD) A stand-alone drug plan or the drug benefit inside a Medicare Advantage plan. | 42 CFR Part 423, Subpart M; exceptions under 42 CFR 423.578. | 65 calendar days from the date on the notice to request a redetermination (42 CFR 423.582, as amended effective 1 January 2025). Formulary, tiering and step-therapy exceptions need the prescriber's supporting statement (§ 423.578). | Redetermination: 7 calendar days standard, 72 hours expedited (42 CFR 423.590). Coverage determinations: 72 hours standard, 24 hours expedited, once the prescriber's statement is received (§§ 423.568, 423.572). | Independent Review Entity reconsideration on your request within 65 days of the redetermination notice (§ 423.600); then ALJ, Council and court. |
| Medicaid managed care plan A Medicaid plan run by the carrier under a state contract. The card says Medicaid, Medi-Cal, STAR, HealthChoice or your state's programme name. | 42 CFR Part 438, Subpart F (plan appeals) and 42 CFR Part 431, Subpart E (state fair hearings). | 60 calendar days from the date on the notice of adverse benefit determination to request the plan's appeal (42 CFR 438.402(c)(2)(ii)). State fair hearing: within 120 calendar days of the plan's appeal decision (§ 438.408(f)(2)). | Standard appeal: 30 calendar days. Expedited: 72 hours (42 CFR 438.408(b)). | A state fair hearing after the plan's single level of appeal (§ 438.402(b)); some states add an external medical review. Benefits continue during the appeal if you ask within 10 calendar days of the notice (§ 438.420). |
What you can demand. The plan must give you the claim file, the internal rule or criterion it relied on, and the identity of the reviewer, free of charge, on request (29 CFR 2560.503-1(h)(2)(iii), (m)(8)).
How to open the appeal. Cite ERISA § 503 and 29 CFR 2560.503-1 in the opening paragraph: request the claim file and the specific criteria relied on, and note the 30-day (pre-service), 60-day (post-service) and 72-hour (urgent) decision clocks.
What you can demand. The plan must give you the claim file, the criteria it applied and any new evidence or rationale before the final decision, free of charge (45 CFR 147.136(b)(2)(ii)(C); 29 CFR 2560.503-1(h)(2)(iii)).
How to open the appeal. Cite 45 CFR 147.136 and 29 CFR 2560.503-1: request the claim file and the criteria, note the decision clocks, and name the state external-review right.
What you can demand. The exception turns on the prescriber's statement that the formulary alternative would be less effective or would harm you (42 CFR 423.578(b)(5)).
How to open the appeal. Cite 42 CFR 423.578 and 423.582 and attach the prescriber's supporting statement written to the exception standard.
What you can demand. Free copies of the case file, medical records and the criteria used, before and during the appeal (42 CFR 438.406(b)(5)). Children under 21 have EPSDT rights to medically necessary care (42 U.S.C. 1396d(r)(5)).
How to open the appeal. Cite 42 CFR 438.402 and 438.406(b)(5): request the case file and the criteria, ask for continued benefits within 10 days, and reserve the state fair hearing.

Patterns we see on OptumRx denials
Separate appeal track from UHC medical
An OptumRx denial is not a UHC medical denial, and vice versa. Filing the wrong appeal track is one of the most common preventable errors. We confirm whether the denial originated at the pharmacy benefit or the medical benefit before filing.
Specialty drug routing through BriovaRx / Optum Specialty
Specialty injectables and infused biologics often route through Optum's specialty pharmacy. Denials at this layer require formulary-exception documentation with clinical rationale, prior-trial data, and (where applicable) FDA-label citation.
Part D coverage determinations
OptumRx-administered Part D plans follow the federal 5-level Part D appeal ladder. The IRE for Part D escalation is MAXIMUS Federal Services. Tiering and formulary exceptions are filed before a coverage-determination challenge.
Coverage determination / exception request, then plan-level redetermination, then external review (IRO commercial; IRE / MAXIMUS for Part D).
Standard exception: 72 hours. Expedited: 24 hours. Redetermination filing window: 65 days from the notice for Part D (42 CFR 423.582), at least 180 days for commercial.
How we file OptumRx appeals
Where the medical and pharmacy benefits both touch the same therapy (e.g. provider-administered biologics), we file parallel appeals in both lanes to avoid a procedural gap.
OptumRx denials: the questions people ask
How long do I have to appeal a OptumRx denial?
Standard exception: 72 hours. Expedited: 24 hours. Redetermination filing window: 65 days from the notice for Part D (42 CFR 423.582), at least 180 days for commercial. Count from the date on the denial letter, not the date you opened it.
Where do I send a OptumRx appeal?
The appeal address, fax number or portal for your specific plan is printed on your denial letter, usually under a heading like "Your right to appeal" or "How to request a review". We deliberately do not publish one address per carrier: OptumRx routes appeals differently by employer group, region, product line and appeal level, and sending it to the wrong place can cost you the deadline. If the letter does not state where to send it, that omission is itself worth raising in the appeal, and the member number on your card reaches someone who must tell you.
What should a OptumRx appeal letter include?
The member and claim numbers, the exact denial reason quoted from the letter, the clinical records that answer that specific reason, and a request in writing for the criteria the decision was based on and a copy of the claim file. Appeals succeed on what you attach more than on how strongly you argue, because the first reviewer often never saw the full chart.
What happens if OptumRx denies the appeal again?
Coverage determination / exception request, then plan-level redetermination, then external review (IRO commercial; IRE / MAXIMUS for Part D). After a final internal denial, external review by an independent organisation is a separate lane, it is free to you, and the decision binds the plan. Which external review applies depends on whether your plan is employer self-funded, state-regulated, Medicare or Medicaid.
