Get the denial and medical-necessity criteria in writing, meet every deadline, use clinician letters and function/safety evidence, request peer review, and escalate to external/state review when available.
What this means in real life
An insurance denial is not the end of the process. Obtain the complete denial notice and identify the exact reason: not covered, not medically necessary, experimental, wrong coding, missing prior authorization, out-of-network or insufficient documentation. The response must match the reason and meet every deadline.
Build evidence around function and risk. A clinician or therapist should explain the diagnosis, current limitation, expected benefit, why alternatives are inadequate and consequences of delay. For equipment, include trials, measurements and feature-by-feature justification. For medicine, cite the current label, mutation/age criteria, prior treatments and monitoring plan. Request peer-to-peer review when useful, but do not let it replace a formal written appeal if deadlines continue.
Escalation may include internal appeal, expedited review, external independent review, state insurance regulator, Medicaid fair hearing or employer-plan process. Rules differ by plan, especially self-funded employer plans.

Questions to bring with you
Use these at the clinic, school meeting, equipment evaluation, program interview or benefits call. Write down the answers and who owns the next step.
- What exact plan provision supports the denial?
- Was required information missing or judged insufficient?
- Is expedited review available because delay risks harm?
- Who conducts external review?
- Can temporary/continued coverage apply during appeal?
Important context
