Why We Need Supporting Documentation

Most of the claims we get don't need documentation, but for some procedures, supporting documentation such as x-rays or charts help us determine if treatment is covered under the patient's benefit plan. For example, a consultant reviews a preoperative x-ray when a claim is received for a cast restoration to see if the contractual criterion has been met for coverage: that so much tooth structure has been lost from caries or fracture that a direct amalgam or resin restoration would not be an adequate restoration.
