In short

  1. You can appeal a work plan denial yourself, with the tools the rules give you.
  2. You get at least 180 days, and a reviewer who did not make the first call [1].
  3. Before the plan rules again, it must hand you any new evidence [2].

What this means

This answer is about a disability plan you get through work. Those plans follow a federal claims rule. That rule hands you four things before you hire anyone.

First, time and a fresh set of eyes. The plan must give you at least 180 days after you get the denial notice to appeal it [1]. The review may not afford deference to the first decision. It must be done by a named fiduciary of the plan who is neither the person who made that decision nor that person's subordinate [1]. A disability plan has to meet those rules too. Its procedures must comply with paragraphs (h)(2)(ii) through (iv) and (h)(3)(i) through (v) [2].

Second, new evidence before the decision. For a disability claim the plan must give you, free of charge, any new or additional evidence it considered, relied on, or generated. And it must do that before it issues an adverse determination on review [2]. So you get to answer the plan's file, not read it afterwards.

Third and fourth, fair deciders and the expert names. Claims and appeals for disability benefits must be handled in a way designed to ensure the independence and impartiality of the people deciding [3]. Pay, hiring, promotion or firing of a claims adjudicator or a medical or vocational expert must not turn on the chance that the person will support a denial [3]. And the plan must identify the medical or vocational experts whose advice it got about your denial, whether or not it relied on that advice [4]. That line is worth quoting in your letter. These sources do not say whether a lawyer will help your case, and they set no fee rule. If you do price one, ask for the fee deal in writing. Social Security disability is a separate system, and this answer does not cover it.

Your next step

Write to the plan and ask for three things. The claim file. The names of the medical or vocational experts it consulted [4]. And the date your 180 days started [1]. Say in the same letter that you want any new or additional evidence before the plan decides [2]. Then collect your own treating records.

Check it yourself

Open your denial letter and find the appeal deadline it states. Compare it with the 180-day floor [1]. Then read your plan booklet appeal section. Whether a lawyer helps your particular case: "Don't know yet" here — these sources do not say.
