Credentialing in Medical Billing: Everything You Need to Know Credentialing in medical billing is mandatory, and insurers require health practitioners. It is so that health providers can serve insurers’ customers after verifying themselves. Credentialing in medical billing is the process that all healthcare service providers perform to become enlisted with insurance companies. Only trusted, vetted, and verified insurance companies include healthcare providers to serve their customers. Upon successful credentialing in medical billing, the healthcare provider is part of an insurer’s network of hospitals, care providers, health centres, clinics, or medical centres. After successfully applying and receiving the credential as a listed service provider, a healthcare operator can receive reimbursements. The reimbursements are received from the insurer. The insurer pays the healthcare operator for the services rendered to their customers by the healthcare operator. The agreement terms between the insurer and healthcare service provider are a contracting or credentialing agreement.
