Before doctors can receive insurance payments, they must be approved by insurance companies. This approval checks education, licensing, and work history to confirm the doctor meets every requirement. Without completing this process, insurers won’t process or pay claims. The step known as physician credentialing acts as a gateway to reimbursement. When done right, it speeds up payment cycles and ensures legal compliance. If skipped or delayed, it can lead to unpaid claims and financial setbacks. For doctors, proper credentialing means fewer headaches and smoother, on-time payments.
