There's not a simple answer to this question as there are dozens of reasons that claims are rejected.
Reimbursify ensures that a claim is accurately submitted and received for adjudication against the patient's individual health insurance plan.
We do not have any influence or control over how an insurance company ultimately finalizes a claim. That said, rejection rates are significantly reduced by submission with Reimbursify because our system prevents users from making common errors related to diagnosis and treatment codes.
