Appeal a Health Insurance Denial in Illinois

Illinois law your appeal letter can cite

Where Illinois law applies to your plan, AppealArmor can cite the provision in your letter, quoting it or summarising it, with its citation. Code picks the provision from the list below, not a model, and only from the official source linked on each one. A provision is used only when your plan is one it covers: state insurance law generally does not reach self-funded employer plans, Medicare or Medicaid. If you are not sure whether your employer plan is self-funded, the provision goes on your Next Steps sheet instead of into the letter. The Next Steps sheet also explains each law used, in plain words.

• Request for external review

  215 Ill. Comp. Stat. 180/25

  A covered person or the covered person's authorized representative may make a request for a standard external or expedited external review of an adverse determination or final adverse determination.

  When your letter uses it: Your plan is an individual plan, or an employer plan you confirm is fully insured (not self-funded). It does not depend on the reason for the denial.
