Provider Enrollment

The process by which a healthcare provider applies to participate in an insurance payer's network, allowing the provider to bill and receive reimbursement for services rendered to the payer's members.

Provider enrollment is the administrative process of getting set up as a participating provider with a specific insurance payer. People often confuse this with credentialing, but they are two different steps. Credentialing verifies your qualifications. Enrollment is what actually gets you into the payer's system so you can submit claims and get paid. The enrollment process varies by payer. For Medicare, you enroll through PECOS (the Provider Enrollment, Chain, and Ownership System). You submit your application online, and CMS processes it through a Medicare Administrative Contractor. For Medicaid, each state has its own enrollment portal and requirements. Commercial payers like UnitedHealthcare, Aetna, and Blue Cross Blue Shield each have their own provider enrollment departments and forms. Many payers now use CAQH ProView as the central data source for enrollment. Instead of filling out separate applications for each payer, you maintain one profile on CAQH and authorize payers to pull your information from there. This saves a significant amount of time, but you still need to complete each payer's specific enrollment process. A common mistake providers make is assuming that once they are credentialed, they are automatically enrolled. That is not always the case. Some payers separate the credentialing decision from the network participation agreement. You might get credentialed (verified) but still need to sign a contract and get loaded into their claims system before you can bill. Effective dates matter enormously. Most payers will not backdate your effective date to when you submitted the application. Some will, some will not. Medicare allows retroactive billing up to 30 days before the effective date in certain situations. Knowing each payer's policy on retroactive billing can save you tens of thousands of dollars in lost revenue during the enrollment period.
