What if your appeal is denied again?
Your options depend on your plan's process, the record you built, and the date your right to sue expires, which your denial notice has to give you.
If your internal appeal is denied, what happens next depends on your specific plan, and there are three possibilities, not two. Some plans offer only one level of internal appeal, after which you have generally exhausted your administrative remedies and can consider a federal lawsuit under ERISA. Some require a second internal appeal, which you generally must complete before you can sue at all. And some offer a second level that is genuinely voluntary, in which case your denial notice should describe those voluntary appeal procedures, alongside the statement of your right to bring an action under ERISA that every appeal denial has to carry.
Do not assume which of the three describes your plan, and in particular do not assume the second level is optional because it is offered. Filing suit before finishing an appeal your plan actually requires can get the case dismissed for failure to exhaust: see one appeal or two.
Whichever path applies, remember that a lawsuit at this stage is often limited to the administrative record you already built (see the administrative record explained), and the standard the court applies depends on whether your plan document contains a discretionary clause (see standard of review). Both of those facts should shape the decision about whether, and how, to proceed, not just whether you feel the denial was wrong.
Find the date your right to sue expires, before you weigh the options
Whichever route you are weighing, a clock may already be running on the litigation option. A plan or policy can set its own deadline for starting a lawsuit, called a contractual limitations period, and for a disability claim the regulation requires the notice denying your appeal to "describe any applicable contractual limitations period that applies to the claimant's right to bring such an action, including the calendar date on which the contractual limitations period expires for the claim."
Read your second denial notice for that date before you decide anything. It matters most here, because a voluntary second appeal takes time, and time is the thing the limitations period is measuring. If the notice does not give the date, ask the plan administrator in writing and keep the request, and raise it with an attorney rather than estimating it yourself. See can you sue after an ERISA appeal denial.
This is the point to talk to an attorney if you have not already
Deciding whether to pursue a voluntary second appeal or go directly to litigation, and understanding what your specific record supports, are exactly the judgment calls an ERISA LTD attorney is positioned to make.

Check your denial letter for what comes next
A second denial letter should tell you directly whether your administrative remedies are now exhausted, or whether a further voluntary appeal is available and, if so, its deadline. Do not assume either answer: read the letter carefully, and if it is unclear whether you have any further internal appeal available, ask the plan administrator in writing rather than guessing and risking a missed step.
If you believe the plan mishandled this second decision too
A second denial that repeats the same procedural problems as the first, such as an unclear basis for the decision or a reviewer who should have been recused, strengthens the record for deemed exhaustion and for any later court challenge. Document what happened at each stage while it is fresh, rather than relying on memory if the case proceeds further.
