Coordination of Benefits

The rules that determine the payment order when a patient has more than one insurance plan, deciding which payer is primary and which is secondary to prevent overpayment. Accurate coordination of benefits at registration is essential for clean ambulatory surgery center claims and avoiding denials.

What is Coordination of Benefits?

Coordination of Benefits is the set of rules that determines the order in which insurance plans pay when a patient is covered by more than one. It establishes which plan is primary and pays first, and which is secondary and may cover remaining amounts, so that the combined payments do not exceed the actual cost of care.

These rules exist to prevent duplicate payment and to clarify each payer's responsibility. Getting the order right depends on accurate information about all of a patient's coverage.

What role does Coordination of Benefits play in the revenue cycle?

For an ambulatory surgery center, capturing complete and accurate insurance details at registration is essential to billing the correct payer first. When Coordination of Benefits is wrong or incomplete, claims are commonly denied or delayed, forcing rework and slowing payment.

Resolving coordination issues up front, before the patient's procedure when possible, leads to cleaner claims and faster, more predictable reimbursement. It is one of the front-end registration tasks that has an outsized effect on downstream collections.
