If an employee's health insurance claim is rejected, the first step is to understand exactly why, because many rejections come down to fixable issues: missing information, a coding error, a treatment that needed pre-approval, or a genuine question over what the plan covers.
A rejection isn't always final, and many are successfully overturned once the case is reviewed and challenged properly. The difficulty is that this work, reading the policy, liaising with the insurer, and escalating the case, usually lands on HR, who have neither the time nor the leverage to fight it.
With AES, that becomes the consultancy's job. A dedicated in-house team reviews the situation, clarifies what is and isn't covered in writing, and takes the issue up directly with the insurer, so your employee gets a proper answer rather than a dead end.
